Purpose: This study aimed to determine predictive factors for low final visual acuity in patients with inactive Vogt-Koyanagi-Harada (VKH) disease using Swept-source OCT and OCT-angiography (OCT-A). Methods: We conducted a prospective longitudinal study, including 21 patients (42 eyes), who were followed up for the first 24 months after disease onset. Patients were included at the acute phase and subsequently treated. Sequential qualitative and quantitative changes in OCT and OCT-A were assessed. Analytical statistical methods were employed to determine predictive factors for final visual acuity. Results: Structural alterations including focal parafoveal outer nuclear layer atrophy, ellipsoid zone disruption, interdigitation zone disruption, and irregular and thickened retinal pigment epithelium line were observed in 57.1% of eyes at month 3, with no significant improvement over time. The presence of flow voids at months 6, 12, and 24 was significantly associated with low final visual acuity. Serous retnal detachment at presentation emerged as an independent risk factor for structural changes detected by SS-OCT during the first 2 years of the disease. Optic disc edema was predictive factor for both structural SS-OCT and OCT-A changes. Conclusion: This study underscores the importance of monitoring flow voids to predict final visual acuity and highlights the impact of serous retinal detachment at presentation on structural changes in patients with inactive VKH disease.

- Abstract
PurposeMethodsResultsConclusionTo provide an overview of pre-selected emerging arboviruses (arthropod-borne viruses) that cause ocular inflammation in humans.A comprehensive review of the literature published between 1997 and 2023 was conducted in PubMed database. We describe current insights into epidemiology, systemic and ocular manifestations, diagnosis, treatment, and prognosis of arboviral diseases including West Nile fever, Dengue fever, Chikungunya, Rift Valley fever, Zika, and Yellow fever.Arboviruses refer to a group of ribonucleic acid viruses transmitted to humans by the bite of hematophagous arthropods, mainly mosquitoes. They mostly circulate in tropical and subtropical zones and pose important public health challenges worldwide because of rising incidence, expanding geographic range, and occurrence of prominent outbreaks as a result of climate change, travel, and globalization. The clinical signs associated with infection from these arboviruses are often inapparent, mild, or non-specific, but they may include serious, potentially disabling or life-threatening complications. A wide spectrum of ophthalmic manifestations has been described including conjunctival involvement, anterior uveitis, intermediate uveitis, various forms of posterior uveitis, maculopathy, optic neuropathy, and other neuro-ophthalmic manifestations. Diagnosis of arboviral diseases is confirmed with either real time polymerase chain reaction or serology. Management involves supportive care as there are currently no specific antiviral drug options. Corticosteroids are often used for the treatment of associated ocular inflammation. Most patients have a good visual prognosis, but there may be permanent visual impairment due to ocular structural complications in some. Community-based integrated mosquito management programs and personal protection measures against mosquito bites are the best ways to prevent human infection and disease.Emerging arboviral diseases should be considered in the differential diagnosis of ocular inflammatory conditions in patients living in or returning from endemic regions. Early clinical consideration followed by confirmatory testing can limit or prevent unnecessary treatments for non-arboviral causes of ocular inflammation. Prevention of these infections is crucial.

This document is a letter to the editor commenting on a study that evaluated the impact of initial management on the disease evolution of Vogt-Koyanagi-Harada (VKH) syndrome. The study classified patients into three groups based on the 2001 revised diagnostic criteria for VKH disease. However, the letter raises concerns about the limitations of the study, including its retrospective design, small sample size, and the mixing of early-stage and late-stage VKH patients in the same cohort. The authors argue that new diagnostic/classification criteria should be used to properly differentiate between early-stage and late-stage VKH disease for improved management and prognosis.

Aims/Purpose: To describe the pattern of acute retinal necrosis (ARN) in a referral centre in Tunisia, North Africa. Methods: The charts of 22 patients diagnosed with ARN from January 2006 to January 2023 were retrospectively reviewed. Results: The mean age at presentation was 39.2 (range, 12–70) years, sex ratio was 1.75. The mean diagnostic delay was 17.9 days (range 1–60). The mean visual acuity at presentation was 20/400. All patients presented with a mild to moderate anterior uveitis (100%) with granulomatous keratic precipitates in 18 eyes (81%) and ocular hypertension in 4 eyes (18%). Necrotizing retinitis involved >50% of the retina in 36.5%of eyes. Polymerase chain reaction on aqueous humour sample identified varicella zoster virus in 10 eyes (45%), herpes simplex virus‐1 in 4 eyes (18%) and was negative in 8 eyes (22%). All patients received intravenous acyclovir, followed by oral antivirals. Intravitreal injections of ganciclovir were administered in 12 eyes (54.5%). Follow‐up ranged from 1 month to 48 months. The mean final visual acuity was 20/200. Complications included retinal detachment (RD) (31.8%), macular oedema (18%), macular atrophy (22%), epimacular membrane (22%), cataract (27%), optic nerve atrophy (18%) and central retinal artery occlusion (4%). No patient developed bilateral ARN. Prophylactic laser was performed in 7 eyes (32%). RD was treated with pars plana vitrectomy and silicone oil injection in 7 eyes. Conclusions: ARN syndrome in Tunisia is most commonly caused by VZV. [ABSTRACT FROM AUTHOR]

Aims/Purpose: To investigate the size and shape of the foveal avascular zone (FAZ) after successful macula‐off rhegmatogenous retinal detachment (RRD) repair using swept source OCT angiography (SS OCTA). Methods: A prospective comparative cross‐sectional study including 21 eyes of 21 patients with macula‐off RRD that were successfully repaired. The size of the superficial FAZ was assessed by its area, length of perimeter, and Feret's diameter, and the shape by the circularity, axial ratio, roundness and solidity. The correlations between each parameter and the clinical and OCT findings were statistically determined. The unaffected fellow eyes were used as controls. Results: The mean initial BCVA was 1.92 ± 0.41 Log MAR (20/2000 Snellen's equivalent). The mean BCVA at OCTA acquisition (3 months) was 0.78 ± 0.39 Log MAR (20/100 Snellen's equivalent) (p < 0.001). FAZ was significantly larger (323.09 ± 129.03 μm2 vs. 245.27 ± 93.15 μm2; p = 0.038), with longer perimeter (2.31 ± 0.35 mm vs. 2.07 ± 0.31 mm; p = 0.048), and irregular shaped (mean circularity: 0.73 ± 0.72 vs. 0.78 ± 0.5; p = 0.019 and mean solidity: 0.90 ± 0.02 vs. 0.93 ± 0.02; p = 0.002) in operated eyes than in the control group. The average Feret's diameter was 0.77 ± 0.10 mm versus 0.71 ± 0.88 mm (p = 0.076). The average axial ratio was 1.25 ± 0.20 versus 1.22 ± 0.22 (p = 0.531), and the average roundness was 0.81 ± 0.11 versus 0.83 ± 0.11 (p = 0.531). Mean central foveal thickness (CFT) was significantly lower in operated eyes than in control eyes (178.23 ± 40.59 μm vs. 247.44 ± 38.2 μm (p < 0.001)). There was a significant inverse correlation between FAZ area and post‐operative outer nuclear layer thickness (r = −0.520, p = 0.016) and CFT (r = −0.571, p = 0.007) in operated eyes. There was no significant correlation between the post‐operative visual acuity and FAZ parameters. Conclusions: Enlargement and irregularities of FAZ after successful macula‐off RRD repair, as demonstrated by SS OCTA, might suggest an ischaemic macular damage caused by RRD that may affect post‐operative functional outcome.

PurposeMethodsResultsConclusionsTo analyze the clinical spectrum of patients with presumed tubercular uveitis in a referral eye clinic in Qatar.We retrospectively reviewed the clinical records of 50 patients (80 eyes) diagnosed with presumed ocular tuberculosis who presented to the uveitis clinic, department of Ophthalmology Hamad Medical Corporation, Qatar, from January 2014 till December 2019.Mean age at presentation was 34.5 ± 9.3 years. Forty one patients were males (82%) and 30 patients had bilateral involvement (60%). Forty eyes (50%) had posterior uveitis, 21 eyes (26.3%) intermediate uveitis, 11 eyes (13.7%) panuveitis, and 8 eyes (10%) anterior uveitis. Ocular findings included vitritis in 82.5% of eyes, retinal vasculitis in 46.3% (92% of which were occlusive in nature), multifocal choroiditis in 18.8%, serpiginous-like choroiditis in 11.3%, Most common complications at presentation or during follow-up included macular edema in 32 eyes (40%), preretinal or optic disc neovascularization in 29 eyes (36.3%) and vitreous hemorrhage in 17 eyes (21.3%). Anti-tubercular treatment was provided to 46 patients (92%). Systemic corticosteroids and corticosteroid sparing agents were associated, respectively, in 39 patients (78%) and 14 patients (28%). After 1 year of follow up, inflammation was controlled, with a significant improvement in visual acuity (
p < 0.0001).In Qatar, tubercular uveitis has a broad spectrum of ocular features, with posterior and intermediate uveitis being the most common anatomic forms. Vitritis, multifocal choroiditis without or with a serpiginous-like pattern, and occlusive retinal vasculitis are the most common ocular findings. Main sight-threatening ocular complications are macular edema, posterior segment neovascularization, and vitreous hemorrhage. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Infectious uveitis is a major global cause of vision impairment. Despite the eye’s immune privilege, afforded by the blood-ocular barrier that restricts microbial entry, several pathogens such as bacteria, viruses, fungi, and parasites can still infiltrate and cause ocular infections and complications. Clinicians often encounter significant challenges in treating infectious uveitis due to limited or ineffective treatment options. Modern molecular techniques and imaging can aid in diagnosing and assessing intraocular infections. Various antimicrobial therapies exist, spanning topical and systemic treatments, but these are constrained by issues like drug concentration, penetration, effective duration, toxicity, and side effects. Treatment approaches also differ based on the infection’s etiology. This review provides recent updates on antimicrobial therapies from a clinical perspective, covering topical, systemic, and regional treatments for infectious uveitis. [ABSTRACT FROM AUTHOR]
