[Diagnostic and treatment options for retinal arterial macroaneurysms in relation to our cases]. / Retinalis artéria macroaneurysmák diagnosztikai és kezelési lehetoségei eseteink kapcsán.

In our report, we present the history of four patients diagnosed with retinal arterial macroaneurysm associated with complications. Our aim is to present the varied appearance of the disease and to present the various therapeutic options. Retinal artery macroaneurysm is a rare, but potentially vision-threatening ophthalmic condition. Macroaneurysm develops from the arteriosclerotic transformation of the artery caused by high blood pressure. Macroaneurysms can be asymptomatic, or they can be associated with exudative or hemorrhagic complication which causes visual impairment. Depending on the symptoms, they can be treated with laser photocoagulation, intravitreal injections, or with vitrectomy. Our presented cases also illustrate that each case requires individual consideration because a uniform therapeutic recommendation is still yet to be developed. In addition to the ophthalmic treatment, it is extremely important to refer the patient to internal medicine. Orv Hetil. 2023; 164(42): 1673-1677.

Optical Coherence Tomography: Focus on the Pathology of Macula in Scleritis Patients.

Optical coherence tomography (OCT) is a non-invasive imaging technique for high-resolution, cross-sectional tissue imaging of the eye. During the past two and a half decades, OCT has become an essential tool in ophthalmology. It is a painless method for examining details of ocular structures in vivo with high resolution that has revolutionized patient care following and treating scleritis patients. METHODS: Twenty-four patients diagnosed with scleritis were selected for this study. All of the patients went through basic ophthalmological examinations, such as visual acuity testing (VA), intraocular pressure measurement (IOP), slit lamp examination, ophthalmoscopic examination, and OCT. OCT examinations were taken by SD-OCT Spectralis OCT system (Heidelberg Engineering, Heidelberg, Germany). RESULTS: Twenty-seven eyes of 24 patients (7 males and 17 females) were included in this study, who were diagnosed with scleritis. OCT examinations showed epiretinal membrane (ERM) in three patients (12%), cystoid macular edema (CME) (three cases, 12%), diffuse macular edema (DME) (one case, 4%), and serous retinal detachment (SRD) (one case, 4%). CONCLUSIONS: OCT proved to be a valuable, non-invasive method for detecting macular pathology in patients with scleritis. Despite the best treatment regimen applied, macular involvement resulting in reduced visual acuity (VA) can develop, which we could detect with OCT since macular edema (ME) is the leading cause of decreased vision due to the damaged outer blood-retina barrier (BRB) in inflammation. OCT investigation is a highly important method for early detection of ocular complications in scleritis in order to prevent blindness.

[Gene therapy treatment based on an ophthalmic indication in hereditary retinal dystrophy caused by RPE65 biallelic gene mutation.] / Szemészeti javallat alapján végzett génterápiás kezelés RPE65 biallelikus génmutáció okozta öröklodo ideghártya-dystrophiában.

INTRODUCTION: Leber's congenital amaurosis is a genetically determined disease belonging to the group of hereditary retinal dystrophies that leads to significant visual impairment in childhood. The disease initially causes a concentric narrowing of the visual field and, with time, loss of central vision. The RPE65 gene mutation-related retinal dystrophy is the first ophthalmic disease for which gene therapy is available using voretigene neparvovec (Luxturna®, Novartis Pharmaceuticals AG, Basel, Switzerland). OBJECTIVE: To present the treatment outcomes of Hungarian patients who were the first to receive voretigene neparvovec gene therapy for the RPE65 biallelic gene mutation. METHOD: Two patients with RPE65 biallelic gene mutations confirmed by genetic testing received voretigene neparvovec gene therapy in one eye each. Before treatment and during the follow-up period, we assessed the best corrected visual acuity, the central retinal thickness, the degree of visual field defects and performed electrophysiological studies. RESULTS: Both the best corrected visual acuity (+3 letters in the older sibling and +10 letters in the younger sibling) and the degree of visual field narrowing improved in both patients. The change in visual function resulted in a significant improvement in the quality of life of our patients. CONCLUSION: Postoperative outcomes of our patients correlate with the results of clinical trials. Orv Hetil. 2022; 163(48): 1923-1931.

Biological therapy of uveitis in children / A biológiai terápia helye a gyermekkori uveitis ellátásában

Introduction: Biological therapy can be used in uveitis in children since 2016. With ophthalmological indication only adalimumab therapy can be started. Adalimumab is a monoclonal antibody that inhibits tumor necrosis factor alpha.Objective: To summarize our experience with patients receiving adalimumab for pediatric non-infectious uveitis.Patients and methods: We investigated our juvenile patients of non-infectious uveitis treated with adalimumab be-tween 2017 and 2021 in a retrospective case series at the Department of Ophthalmology, Szeged University. Results: Between 01 January, 2017 and 31 May, 2021, we examined 46 children with uveitis. The mean age of these 23 girls and 23 boys was 11 years. 21 of them had juvenile idiopathic arthritis, 14 had infectious uveitis, 3 had hae-matological disorders, 8 had idiopathic uveitis. Adalimumab was given to 11 patients because of severe, chronic uveitis. There were 3 boys and 8 girls, their mean age was 10 years. Adalimumab was given according to the licence of the European Medicines Agency. Indication was anterior uveitis at 6 children, panuveitis at 5 children. Adali-mumab can be given to children over 2 years, who have chronic, non-infectious, anterior uveitis. Children with panuveitis received the therapy by the help of a pediatric rheumatologist.Conclusion: The significance of pediatric uveitis and its therapy is emergent. Our aim was to preserve vision and de-crease the possibilities of side effects and to provide a better life for these uveitic children. Early diagnosis, adequate therapy and regular ophthalmological check-ups are important. Children treated with adalimumab have good visual acuity due to the effectiveness of the therapy. No new ocular side effect was detected at the children treated with adalimumab.

White Dot Syndrome Report in a SARS-CoV-2 Patient.

Our purpose was to report clinical features in bilateral white dot syndrome in a 47-year-old female patient who was tested positive for the SARS-CoV-2. A 47-year-old female visited our department with complaints of bilateral photophobia and blurred vision in both her eyes. She visited our department during the pandemic period after her PCR-proven SARS-CoV-2 positivity. Her symptoms were chills and fever with a temperature of 40.0°C, associated with fatigue, sweat, and complete loss of taste. Besides basic ophthalmological examinations, ocular diagnostic testing were made to differentiate between specific white dot syndromes with suggestive features of fluorescein angiography, optical coherence tomography, and fundus autofluorescence. Laboratory tests were ordered, including immunserological and haematological ones. Eye examination revealed mild bilateral vitritis and white dots in the fundus of both eyes, including the macula explaining the blurred vision. Herpes simplex virus reactivation was proved, after the SARS-CoV-2 infection. Local corticosteroids were given according to the European Reference Network's recommendations for patients with uveitis during the COVID-19 pandemic. Our report demonstrates that white dot syndrome with blurred vision could be associated with SARS-CoV-2 infection, being potentially sight-threatening because of macular involvement. Ophthalmological examinations found posterior uveitis white dot syndrome, and this should call attention to the risk of acute 2019-CoV infection or occurred 2019-CoV infection. Immunodeficiency favours the occurrence of other viral infections, such as herpes virus infections. Everybody should be aware of the risk of 2019-CoV infection, especially professionals, social workers, and those who work or live with elder people and people with immunodeficiency.
