AIM: The aim of the article is to summarize observations on cytomegalovirus (CMV) anterior uveitis, and in short case reports present cases of patients treated at our Department of Ophthalmology, First Faculty of Medicine, Charles University and General University Hospital in Prague. MATERIAL AND METHODS: Retrospective analysis of patients at the Centre for diagnosis and treatment of uveitis from 2003 to 2024. Presentation of our experiences with CMV anterior uveitis confirmed by polymerase chain reaction (PCR) in aqueous humor in case reports. RESULTS: From a cohort of 3844 patients with uveitis, 3 patients were diagnosed with CMV anterior uveitis, confirmed by PCR in the aqueous humor. The clinical presentation was as acute recurrent hypertensive anterior uveitis in all patients, with a switch to chronic form with elevated intraocular pressure (IOP). Despite local anti-inflammatory and antiglaucomatous therapy, there was high recurrence of uveitis with decompensation of IOP when the medication was reduced. Patients underwent antiglaucoma surgery because of persistent high IOP despite maximal local antiglaucomatous therapy. An anterior chamber tap was taken for PCR analysis, with a CMV-positive result. After the initiation of antiviral therapy with local ganciclovir, patients manifested compensated IOP and a pronounced reduction of recurrences of uveitis and progression of glaucoma. CONCLUSIONS: CMV anterior uveitis is a rare pathology in our geographic region, but it is important to consider this etiology in cases of recurrent anterior hypertensive uveitis with a low response to local anti-inflammatory medication. Timely verification of the etiological agent with prompt diagnosis and treatment is essential in order to achieve a favorable prognosis. Long-term, low maintenance doses of antiviral therapy with local ganciclovir for several months reduce relapses of uveitis and lead to compensation of IOP.

AIM: to investigate the dynamics of the T-cell immune response in rabbits with experimental autoimmune uveitis (EAU) of varying severity. MATERIALS AND METHODS: The experiment involved two groups of Chinchilla rabbits (15 rabbits in each group). The model of EAU was created. The clinical picture of intraocular inflammation of varying severity was assessed. The determination of the level of white blood cells (WBC), lymphocytes (Lymphs), CD3+, CD4+, CD8+, and CD16+ in the blood of rabbits was conducted. RESULTS: Group I - moderate and severe uveitis, Group II - uveitis of mild severity. WBC, Lymphs, CD3+, CD4+, CD16+ were elevated and statistically significant in both groups of animals compared to control parameters on all days of the experiment (3, 7, 10, 14, 21 days) (p.

PURPOSE: Evaluation of the effectiveness of pneumatic vitreolysis in disrupting vitreomacular traction in our own cohort of patients. METHODOLOGY: Prospective follow-up of 21 eyes of 18 patients with focal VMT (adhesion width < 1500 µm) who underwent intravitreal injection of 0.3 ml of 100% perfluoropropane between January 2015 and December 2020. The patients were observed for 90 days. RESULTS: Release of VMT was achieved on the 28th day of observation in 15 out of 21 eyes (71.4%), and by the 90th day in 19 out of 21 eyes (90.5%). The average width of adhesion in our patients was 382 µm (±212 µm). Average best corrected visual acuity in our cohort was initially 0.77 (±0.21), after 28 days 0.74 (±0.30), and after 3 months 0.82 (±0.21). At the end of the follow-up period, we did not observe a statistically significant improvement in vision. Macular holes developed in two eyes, but spontaneously closed within 1 month of observation, and no more complications were observed in the cohort. CONCLUSION: Pneumatic vitreolysis by intravitreal injection of C3F8 gas is an effective and inexpensive option for the management of symptomatic vitreomacular traction. The incidence of serious adverse events in our follow-up was significantly lower than in recently published series. The method of management should be selected individually according to the parameters of adhesion, macular hole and associated ocular pathologies.

AIM: The main aim of this study is to evaluate the anatomical and functional results of pars plana vitrectomy (PPV) with peeling of the internal limiting membrane (ILM), membrane blue staining and subsequent expansile gas tamponade (perfluoropropane) in the treatment of idiopathic macular hole (IMH). MATERIAL AND METHODS: The retrospective analysis consisted of 100 eyes of a total of 100 patients (61 women and 39 men) with IMH, operated on at the Department of Ophthalmology of the Slovak Medical University and University Hospital Bratislava from 1 January 2021 to 1 January 2024, using 25-gauge PPV with ILM peeling and perfluoropropane tamponade (C3F8) of 15% concentration. After surgery, the patients were required to remain in a face-down position for at least one week. Best corrected visual acuity (BCVA), minimal linear diameter (MLD) on optic coherence tomography, macular hole closure type and occurrence of complications were evaluated. The obtained results were expressed with the use of arithmetic averages and displayed in graphs. RESULTS: Primary closure of macular hole was achieved in 93 patients (93%). The most frequently occurring type of closure was 1A. After surgery, the BCVA of all patients improved, from an average value of 0.101 preoperatively to 0.300 one year after surgery. In all groups of patients (regardless of the size of the macular hole before surgery), during the one-year follow-up period there was a gradual increase in BCVA with its stabilization by 6 months. The main factors that influenced postoperative BCVA were the preoperative values of MLD and BCVA. CONCLUSION: PPV with ILM peeling and perfluoropropane tamponade is an effective treatment for idiopathic macular holes with a success rate of more than 90%. This surgical procedure, associated with a relatively low number of complications, brings patients a definite improvement of BCVA.

Adult-onset foveomacular vitelliform dystrophy (AOFVD) is a rare disease characterized by accumulation of yellowish deposits in the macula. Rarely, it may be complicated by choroidal neovascularization (CNV). Cases with CNV may be confused with occult CNV in age-related macular degeneration. In our case, we will present the visual and anatomical results of a patient with AOVF-related CNV, in which we administered 3 doses of intravitreal ranibizumab (IVR). A 59-year-old female patient, who attended our clinic with the complaint of decreased vision in both eyes, was diagnosed with AOVF-related CNV in both eyes and was treated with 3 doses of IVR for 3 months. Despite the improvement in visual and anatomical functions 1 month after the first dose, vision decreased, and anatomical functions regressed to the pre-injection state in continued injections. IVR therapy is not an appropriate treatment option in the treatment of AOVF-associated CNV.

AIM: This retrospective clinical study evaluates the results of surgical treatment of patients diagnosed with intermittent exotropia of the divergence excess type. The study compares the results of surgery delayed due to the Covid-19 pandemic (patients underwent the surgery after the age of eight), versus a group of younger children. MATERIALS AND METHODS: The objective angle of deviation and quality of binocular functions were examined. The follow-up period was six months after surgery. The patients were divided into two groups according to age: 4-7 years and 8-13 years. Each group included 20 patients. The second group comprised patients whose surgery was postponed due to restrictions on elective surgery during the ongoing pandemic. The surgery took place at the University Hospital in Pilsen. Angle of deviation and binocular functions were examined before surgery, postoperatively, and three and six months after surgery. Data were collected retrospectively and statistically processed. The main values were plotted in charts. RESULTS: Accordance between the angle of deviation before surgery in both groups was statistically demonstrated. During the six-month follow-up period, the median angle of deviation was statistically without proof of disparity between the groups. Six months after surgery, an objective angle of deviation within the limit ±5 degrees was achieved in 65% of patients from the first group and in 75% from the second group. Binocular vision before surgery was statistically without proof of difference between both groups. However the statistical processing demonstrated a difference between the two groups six months after the surgery. Better binocular functions were achieved by the younger children in the first group. CONCLUSION: The objective deviation angle was comparable in both study groups prior to surgery as well as six months after the surgery. The first group of younger patients attained a higher quality of binocular functions within the six-month follow-up period compared to children operated on after the age of eight. This claim was statistically verified.

AIM: To summarize the history and current trends in the use of scleral grafts in ophthalmology. MATERIALS AND METHODS: We conducted a review of the literature through the MEDLINE and Cochrane Library databases. The search terms were "sclera", "graft", and "surgery". The search resulted in 1596 articles, of which we evaluated 192 as relevant. The relevant articles were sorted chronologically and according to the method of using scleral grafts, which enabled the development of a review article. RESULTS: The sclera has been routinely used in ophthalmology since the 1950s in many different indications. Some of these indications have become practically obsolete over time (for example, use in the surgical management of retinal detachment), but a large number still find application today (especially use in glaucoma or oculoplastic surgery, or as a patch for a defect in the sclera or cornea). CONCLUSION: Even though allogeneic sclera is currently used less frequently in ophthalmology compared to other tissue banking products and the range of its indications has partially narrowed, it remains a useful material due to its availability and properties.

The authors present a case of a thirty-eight-year-old patient with Alport syndrome. The patient had several ocular symptoms of the disease and has been treated for systemic problems in connection with Alport syndrome since he was fifteen years old. At that age the patient also underwent a kidney transplant in order to deal with renal insufficiency. To date, he still uses immunosuppressants and antihypertensives. Furthermore, the patient suffers from perceptive deafness. The patient visited our clinic in 2021 with a request to solve his high refractive error, in which the diopters were so high that it was not possible to place them in spectacles. The patient's best corrected visual acuity was 0.6 with -8.0sph/-4.0cyl/ax15 in the right eye and 0.7partim with -8.0sph/-4.0cyl/ax155 in the left eye. The autorefractometer values were -6.25sph/-6.75cyl/ax17 in the right eye and -6.75sph/-6.5cyl/ax155 in the left eye. During the eye examination we found a number of ocular manifestations that are typical of Alport syndrome. On the cornea there were opacities as a residue of corneal erosions, and at one of the following check-ups we also found a newly developed corneal erosion. Subsequently, we found an anterior lenticonus and incipient cataract. Upon performing OCT, a typical temporal macular atrophy was evident. Fundus examination in artificial mydriasis showed just a minimal manifestation of fleck retinopathy. Due to the clinical manifestation we decided to perform cataract surgery and implant a monofocal toric intraocular lens in both eyes. There were no complications during the operations, however the surgeon registered a non-standard structure of the lens capsule. The capsule was more fragile, and performing capsulorhexis was much more complicated. A week after the surgery, higher cylinder diopters were still present. A decrease of the higher diopters was noticeable one month after surgery. The time interval between the first operation and the second operation was one month. The patient was highly satisfied with result, and uncorrected visual acuity improved by over four lines. After surgery the patient needed low diopters for near as well as far distance. In the case of this patient, the ocular manifestations were detected and treated in adulthood. Nevertheless, early detection of ocular symptoms of Alport syndrome in young patients before renal failure could lead to timely start of the treatment and delay a possible renal transplant. In case of any suspicion of Alport syndrome it is advised to send the patient to a pediatrician, and at an older age to an internal medicine specialist, for further examination.

This article presents an overview of treatment regimens of drugs containing antivascular endothelial growth factor for the treatment of neovascular form of age-related macular degeneration. Currently, drugs containing antivascular endothelial growth factor are the only effective treatment for this chronic and progressive disease. The treatment regimens for this disease in the last two decades have seen a shift from a simple endeavor to stabilize the disease to achieving maximum improvement of visual acuity and its maintenance, with improvement of the patient's quality of life and a minimal treatment burden on patients and their families. Other goals of the alternative dosing regimens that have replaced the original fixed regimens were greater individualization of the dosing regimen, better patient cooperation, saving financial costs and reducing the burden on application centers. Age-related macular degeneration, whether dry form or wet form, represents a serious health and socioeconomic problem, as the disease is one of the most common causes of severe and irreversible central visual acuity disorders up to the degree of practical blindness of one or both eyes in people over 50 years of age in developed industrialized countries. The most important issue is to ensure early diagnosis of this disease, followed by prompt and continuous treatment with an individualized proactive treatment regimen, with the aim of stabilizing and improving anatomical and functional results.

AIM: The primary aim of this study is to evaluate the repeatability of noninvasive break-up time (NIBUT) measurement by keratograph when it is determined from one, two or three partial measurements, and to recommend a suitable methodology for practice. Another goal is to verify that repeated measurements do not affect the measured value. MATERIAL AND METHODS: Thirty-eight healthy volunteers (30 women and 8 men) aged between 19 and 50 years old were included in the study, in which only one eye of each volunteer was measured. The study was designed as a prospective one. Each subject adapted to the local conditions of the laboratory for 15 minutes and subsequently underwent two series of NIBUT measurements (test, retest) on an OCULUS 3 Keratograph. The minimum time interval between the two series was 10 minutes, in which each series contained three partial measurements approximately 3 three measurements in the given series. Repeatability was assessed by a Bland-Altman analysis and expressed as a repeatability coefficient. In every case, only the time of the first break-up of the tear film was monitored. RESULTS: The statistical analysis did not show statistically significant differences both between partial measurements of NIBUT in the individual series (p = 0.92, p = 0.81) and when comparing all six measurements (p = 0.95). The mean values of the partial measurements ranged from 13.6 s to 14.4 s. The repeatability coefficients were found to be 15.0 s, 12.1 s and 10.0 s for methodologies A, B and C, respectively. A supplementary analysis for 12 eyes with low NIBUT (< 10 s) showed statistically significantly better repeatability in this group, with coefficients of 7.0 s (methodology A), 6.0 s (B) and 4.6 s (C). CONCLUSION: Determination of NIBUT from three consecutive measurements (with a sufficient interval of ideally a few minutes) significantly improves repeatability. Such repeated NIBUT measurements do not have a significant effect on the measured value. The mentioned methodology for measuring NIBUT on a keratograph can be recommended for use in practice.

AIM: To demonstrate a rare case of ciliary body leiomyoma in our patient Case report: A 72-year-old female reported to our clinic for a preventive examination, upon which we found a dome-shaped grey-brownish mass on the retinal periphery. After completing gonioscopic and ultrasound examinations, we referred the patient to a specialist facility. Due to a finding of suspicious malignant melanoma, we completed the MRI scan and recommended enucleation of the eyeball. A histopathological examination showed a leiomyoma of the ciliary body. CONCLUSION: The aim of this case report is to demonstrate the difficulty of intraocular leiomyoma diagnosis. Only immunohistochemical examination differentiated the tumor from malignant melanoma and determined the diagnosis of ciliary body leiomyoma. Perhaps because of the extreme rarity of this type of tumor, we often neglect to consider a diagnosis of leiomyoma.

AIM: Iridocorneal endothelial (ICE) syndrome is a rare disease characterized by abnormal proliferation and structural changes of the endothelium, obliteration of the iridocorneal angle, and anomalies of the iris. The consequence of these changes is secondary glaucoma and corneal decompensation. The etiology is unclear, and the syndrome more commonly affects middle-aged women. CASE REPORTS: In this article we present two different case studies of young patients diagnosed with ICE syndrome with complications. The first case report is about a young woman in whom surgical treatment of glaucoma and corneal edema was successful. On the other hand, the second report presents a complicated case of a 29-year-old patient whose treatment was not successful despite repeated interventions. CONCLUSION: This text highlights the complexity of ICE syndrome, the difficulty of its therapy and the importance of early diagnosis.

OBJECTIVE: The aim of this study was to evaluate the outcomes of Ozurdex® (DEX) implant in patients with diabetic macular edema (DME) in real-world clinical practice, and to determine the correlation between known OCT biomarkers and the effect of treatment. MATERIAL AND METHODS: This retrospective study included 42 eyes of 33 patients (16 women, 17 men) treated with DEX at the Department of Ophthalmology, Faculty of Medicine and Dentistry of Palacký University and University Hospital Olomouc for DME indication between 2020 and 2023. Follow-up examinations were conducted at 1, 3, and 6 months after the first DEX application. The main assessed parameters were: best-corrected visual acuity (BCVA), intraocular pressure (IOP), central retinal thickness (CRT), OCT biomarkers. The results were subsequently statistically evaluated. RESULTS: At the first follow-up after DEX application, there was an average decrease in CRT of 186 ±146µm and a gain of 3 ±7 letters. Positive morphological and functional responses were observed in 39 eyes (92.9%) and 23 eyes (54.8%) respectively. The disorganization of retinal inner layers (DRIL) biomarker was initially present in 41 eyes (97.6%), with reduction or disappearance observed in 13 eyes (31%) post-application. Eyes with ellipsoid zone disruption (EZ disruption) had an average initial BCVA of 49.6 letters, compared to 57.8 letters in the group without this biomarker. The mean gain in BCVA was +8.7 letters in treatment-naive eyes and +2.1 letters in previously treated eyes. Chronic DME was less frequent in treatment-naive (n = 1, 14.3%) compared to previously treated eyes (n = 28, 84.8%). All these results were statistically significant (p < 0.05). An increase in IOP post-DEX application occurred in 9 patients (21.4%). CONCLUSION: Our results confirm DEX as a safe and effective treatment option for DME. Treatment-naive patients achieved better functional outcomes. We confirmed ellipsoid zone disruption (EZ disruption) as a negative biomarker. Additionally, we demonstrated the capacity of DEX to reduce disorganization of the retinal inner layers (DRIL).

AIM: This research was conducted to determine the normal values of choroidal thickness in healthy individuals and to evaluate the relationship between this thickness and age, gender, refraction, axial length and average macular thickness using OCT. MATERIAL AND METHOD: In the study, the right eyes of 400 healthy individuals (234 women, 166 men) between the ages of 4 and 70 years, who applied to the Department of Ophthalmology outpatient clinic for examination, were evaluated. RESULTS: Macular thickness, macular volume, and foveal thickness were found to be 249.12 ±21.32 µm, 9.98 ±0.5 µm3 and 280 ±13.45 µm, respectively. According to linear regression analysis, a negative correlation was detected between age and subfoveal choroidal thickness (p < 0.05). It was determined that foveal thickness, retinal volume and average retinal thickness were higher in men, and foveal thickness increased with age (p < 0.05). CONCLUSION: As a result of the research, it was determined that age is an important factor affecting choroidal thickness. It is thought that, in future, improving in vivo imaging of the choroid and measuring choroidal thickness using OCT will facilitate understanding of the pathophysiological basis of many ophthalmological diseases.

AIM: To compare functional and anatomical outcomes between the inverted flap technique and conventional removal of the internal limiting membrane (ILM) in the surgical management of idiopathic macular hole (IMH). MATERIAL AND METHODS: We retrospectively evaluated the anatomical and functional results in 67 eyes of 65 patients operated on for IMH. The patients were operated on either using the conventional ILM peeling technique (first group) or with the inverted ILM flap technique (second group). 43 eyes of 41 patients were included in the first group, 24 eyes of 24 patients in the second group. We indicated for surgery only patients with IMH stage 2-4 according to the Gasse classification. Best corrected visual acuity (VA) was always determined before and two months after surgery. Furthermore, a comparison of both techniques was made according to the average letter gain after surgery, and the effect of surgery was evaluated using OCT with regard to whether IMH closure succeeded. For both techniques, 25G PPV with SF6 tamponade was performed. RESULTS: Hole closure took place in 41 eyes with conventional ILM removal. In one eye, the hole did not close even after reoperation with the same technique. Median ETDRS letter gain was 7.0. VA remained the same in 2 eyes (4.7%), worsened in 7 cases (16.2%), and improved in all other cases (79.0%). In 16 eyes (37.2%), VA improved by 2 or more lines of ETDRS charts. Using the inverted flap technique, the hole was closed in all 24 monitored eyes. Median ETDRS letter gain was 9.5. VA remained the same in 2 eyes (8.3%), worsened in 2 cases (8.3%), and improved in all other cases (83.3%). In 12 eyes (50.0%), VA improved by 2 or more lines of ETDRS charts. There were no serious complications intraoperatively or postoperatively. CONCLUSION: Our study demonstrated the safety and efficacy of both methods. Although the results were not statistically significant, the inverted flap technique recorded a greater ETDRS letter gain (9.5 vs. 7.0) and proportion of closed holes (100% vs. 95.3%) compared to the conventional ILM peeling technique in our set of eyes.

AIMS: To investigate the concordance between the corneal power determined by various approaches with two tomographers (MS-39® and Galilei G6®) and the clinical history method (CHM) in patients undergoing photorefractive surgery with excimer laser for myopic errors. MATERIAL AND METHODS: Prospective cohort study. Patients undergoing keratorefractive surgery, and having pre- and postoperative keratometries, and tomographies, were included. RESULTS: In 90 eyes, the differences in the power estimated by the CHM and the one determined by four approaches with the corneal tomographers, which included measurements of the posterior cornea, did not show statistically significant differences in their averages. However, the 95% limits of agreement were very wide. After obtaining regression formulas to adjust the values of these four variables, the results of the agreement analysis were similar. CONCLUSION: Although certain values either directly determined or derived from measurements with the Galilei® and MS-39®corneal tomographers, approximated the estimated value of postoperative corneal power according to the CHM, due to the amplitude of their limits of agreement, these calculations must be taken with care, because they may not be accurate in a given eye.

The aim of the thesis is to present the case of a patient in whom bilateral calcification of the hydrophilic intraocular lens (IOL) Lentis M+ LS-313 MF30 (Oculentis) has developed. Due to the negative effect on visual functions, explantation and replacement of the artificial lens was necessary in both eyes. Case Report: An overview of the available literature summarized the diagnostics, current examination methods and possibilities of the surgical solution of calcification of the bifocal hydrophilic lens Lentis M+ LS-313 MF30 (Oculentis). The specific solution is described in a case report of a patient in whom calcification of both lenses developed 6 years after implantation of the IOL. In 2015, the patient underwent uncomplicated cataract surgery of both eyes with the implantation of an artificial intraocular lens into the capsule. In September 2021, an 82-year-old man was examined at our outpatient clinic for deterioration of visual acuity and changes in the material of the artificial IOL which were perceptible during a clinical examination, on the recommendation of a local ophthalmologist. Blurred vision predominated. A diagnosis of intraocular lens opacification was confirmed and documented using a Scheimpflug camera (OCULUS Pentacam HR) and anterior OCT (Avanti RTVue XR Optovue,). The patient was indicated for explantation and replacement of the opacified intraocular lens in the left and subsequently in the right eye- The same type of IOL was used for reimplantation with good functional results. Conclusion: Since 2010, multifocal lens implantation has been on an upward trend worldwide. This type of MF IOL has also been used in thousands of implantations. A number of other explantations can be expected in the coming years. The optimal solution is the correct replacement of the calcified IOL with the same construction made of safer hydrophobic material.

AIM: To determine the effect of repeated intravitreal injections of aflibercept on the corneal endothelium in patients with diabetic macular edema (DME) and macular edema due to retinal vein occlusion (RVO). METHODS: In a prospective study conducted between January 2021 and November 2023, a total of 87 treatment-naive eyes with DME and RVO were evaluated. The exclusion criteria were surgery or laser intervention during the follow-up period, contact lens wear, cataract surgery in the last 6 months, dystrophy, or other corneal condition that may cause endothelial damage. In addition to routine examinations on the day of application, we also measured the corneal endothelium using specular microscopy on the 1st, 4th and 8th day of injection. We evaluated 4 parameters: endothelial cell density (CD), hexagonality (HEX), coefficient of variability (CV) and central corneal thickness (CCT). First of all, we evaluated the entire cohort of eyes, and then divided it according to 2 criteria; the diagnosis into DME/RVO and according to the lens status into phakic/pseudophakic eyes. RESULTS: A total of 87 eyes of 68 patients were evaluated. The average age of the patients at the time of diagnosis was 66.8 ±9.3 years. Within the cohort 51 (59%) eyes were phakic and 36 (41%) pseudophakic. A total of 61 (70%) eyes with a diagnosis of DME were treated, and 26 (30%) with RVO. During the follow-up, there were no significant changes in the average values of CD, HEX, CV, CCT due to aflibercept treatment, either in the whole group or in subgroups according to diagnosis or lens condition. CONCLUSIONS: The results of this study suggest that intravitreal administration of aflibercept in patients with DME and RVO did not have an impact on corneal endothelial parameters, including CCT, HEX, CD and CV. These parameters were measured using endothelial microscopy during an 8-injection observation period.

PURPOSE: To draw attention to the higher proportion of Fuchs heterochromic iridocyclitis (FHI) cases in patients with multiple sclerosis (MS). MATERIALS AND METHODS: Retrospective study of data collected at the Center for the Diagnosis and Treatment of Uveitis. RESULTS: An analysis of the medical records of 3016 patients with uveitis (in the years 2003-2020) was performed with a focus on MS. MS-associated uveitis was diagnosed in 90 patients (3%): anterior uveitis (n = 7), intermediate uveitis (n = 23), retinal vasculitis (n = 24), and panuveitis (n = 36). A clinical examination revealed signs of FHI in the anterior segment in 11 out of 90 cases (12%). Atypical manifestations of FHI included a higher incidence of bilateral involvement (45%), retinal vasculitis (27%), and vitreous snowballs (18%). The diagnosis of FHI preceded the diagnosis of MS in 4 cases. The median latency was 10.5 (range 8-15) years. In 4 patients, the diagnosis of demyelinating disease was established within one year of the diagnosis of FHI. We recommended a neurological examination for optic neuritis (n = 1), paresthesia (n = 3), relapse of motor deficit (n = 1), and screening of etiology in cases with involvement of the posterior segment (n = 3). In the other 3 cases, the diagnosis of MS preceded the diagnosis of FHI, with a median latency of 13 (range 8-19) years. CONCLUSION: We detected clinical symptoms of FHI in 12% of uveitis cases associated with MS, more often in bilateral manifestations of intraocular inflammation. Based on our experience, we recommend an investigation of the medical history of patients with FHI for manifestations of sensitive, sensory and motor deficits, especially in bilateral cases.

This article presents a summary of recent advances in the development and use of complex systems using artificial intelligence (AI) in neuro-ophthalmology. The aim of the following article is to present the principles of AI and algorithms that are currently being used or are still in the stage of evaluation or validation within the neuro-ophthalmology environment. For the purpose of this text, a literature search was conducted using specific keywords in available scientific databases, cumulatively up to April 2023. The AI systems developed across neuro-ophthalmology mostly achieve high sensitivity, specificity and accuracy. Individual AI systems and algorithms are subsequently selected, simply described and compared in the article. The results of the individual studies differ significantly, depending on the chosen methodology, the set goals, the size of the test, evaluated set, and the evaluated parameters. It has been demonstrated that the evaluation of various diseases will be greatly speeded up with the help of AI and make the diagnosis more efficient in the future, thus showing a high potential to be a useful tool in clinical practice even with a significant increase in the number of patients.
