Purpose: To describe the clinical, optical coherence tomographic, and angiographic findings in patients with acute toxoplasmic retinochoroiditis (RC) associated with serous retinal detachment (SRD). Methods: The study included 60 eyes with acute toxoplasmic RC. Results: Of 60 eyes, 14 (23.3%) were found to have SRD. The SRD was visible on fundus examination in 6 cases and detectable only by optical coherence tomography (OCT) in the 8 remaining cases. It involved the fovea in 9 eyes. There was evidence of associated choroidal ischemia on fluorescein angiography and indocyanine green angiography in 5 eyes. Findings seen at the acute stage gradually resolved over a period of 2-6 weeks in all patients. Conclusions: SRD, accurately detected by OCT, is a common complication of acute toxoplasmic RC that should be considered as a potential cause of visual loss. Choroidal ischemia might contribute to the development of such complication. [ABSTRACT FROM AUTHOR]

: PurposeTo characterize and analyze the posterior segment manifestations of Mediterranean spotted fever (MSF), an infectious disease caused by Rickettsia conorii.: DesignProspective, noncomparative case series.: ParticipantsThirty patients (60 eyes) with serologically proven MSF at the acute stage.: MethodsPatients underwent complete ophthalmic examination, including dilated biomicroscopic fundus examination, fundus photography, and fluorescein angiography. Sequential follow-up examinations were performed in patients with evidence of posterior segment involvement.: ResultsOf 30 patients, 25 (83.3%) had unilateral (n = 5) or bilateral (n = 20) posterior segment involvement related to MSF. Of those 25 patients, 16 (64%) had no ocular symptoms, and 9 (36%) had ocular complaints. Findings included mild vitreous inflammation (45 eyes [75%]), white retinal lesions (18 eyes [30%]), focal vascular sheathing (5 eyes [8.3%]), multiple arterial plaques (1 eye [1.7%]), intraretinal hemorrhages (14 eyes [23.3%]), white-centered retinal hemorrhages (2 eyes [3.3%]), subretinal hemorrhages (2 eyes [3.3%]), serous retinal detachment (3 eyes [5%]), macular star (2 eyes [3.3%]), cystoid macular edema (1 eye [1.7%]), optic disc edema (1 eye [1.7%]), branch retinal artery occlusion (1 eye [1.7%]), optic disc staining (30 eyes [50%]), retinal vascular leakage (27 eyes [45%]), delayed filling in a branch retinal vein (1 eye [1.7%]), and multiple hypofluorescent choroidal dots (10 eyes [16.7%]). One eye (1.7%) had retinal neovascularization at the 6-month follow-up examination. All posterior segment findings at the acute stage resolved in 3 to 10 weeks, and the final visual acuity was 20/20 in 42 of 45 affected eyes (93.3%). Retinal pigment epithelium changes developed in 9 eyes (15%), with resolved full-thickness white retinal lesions. No other abnormalities were noted in the eye with retinal neovascularization over a further follow-up of 6 months.: ConclusionPosterior segment involvement, frequently asymptomatic, is common in patients with acute MSF. Because the diagnosis can be easily overlooked, a careful dilated funduscopic examination, complemented by fluorescein angiography in selected cases, is recommended. Mild vitritis, retinal vasculitis, optic disc staining, white retinal lesions, retinal hemorrhages, and multiple hypofluorescent choroidal dots are the most common manifestations of MSF. Posterior segment changes in a patient with fever and/or skin rash living in or returning from a specific endemic area, especially during the spring or summer, strongly suggest R. conorii infection.

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.

The fundus photographs provided show deep yellowish lesions, multifocal exudative retinal detachments, and optic disc hyperemia in both eyes. Spectral domain optical coherence tomography scans shown demonstrate bilateral exudative retinal detachments involving the macula in the right eye. The exudative retinal detachment is characterized by the presence of subretinal fibrin and septa. The B-scan ultrasonography provided shows low- to medium-reflective choroidal thickening predominating around optic nerve head, in association with exudative retinal detachment in the right eye. All these findings are highly suggestive of acute Vogt-Koyanagi-Harada (VKH) disease rather than multifocal choroiditis. [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.

Purpose: To report a case of Vogt‐Koyanagi‐Harada (VKH) disease following a serology‐confirmed bartonella henselae retinitis. Methods: A single case report. Results: A 41‐year‐old female patient presented with a central scotoma in her right eye (RE). Fundoscopic examination showed a focal retinitis with a macular star in the RE. Work‐up revealed positive bartonellosis serology. The patient was treated with oral azithromycine and oral steroids during 4 weeks with subsequent healing of the retinitis lesion. Three months after initial presentation, the patient complained of loss of vision in both eyes. Ophthalmological examination showed a best‐corrected visual acuity (BCVA) of 20/200 on both eyes, with a bilateral granulomatous panuveitis with bilateral multifocal exudative retinal detachment. Results of multimodal imaging were consistent with the diagnosis of acute VKH disease. Given the history of positive bartonellosis serology, the patient was treated with doxycycline (200 mg/day) for 6 weeks in association with intravenous methylprednisolone for 5 days followed by oral steroids and progressive tapering. At three‐month follow‐up, BCVA improved to 20/20 in both eyes associated with resolution of clinical and structural OCT changes. Conclusions: Our case suggests that bartonella henselae infection might be a non‐previously reported infectious trigger of VKH disease in genetically predisposed patients. Alternatively, bartonella henselae infection might manifest with panuveitis mimicking VKH disease. [ABSTRACT FROM AUTHOR]

Purpose: To describe restoration of outer retinal layers on Swept‐Source OCT (SS OCT) in Vogt Koyanagi Harada (VKH) disease over a year after the disease onset. Methods: Prospective longitudinal study carried out at the department of Ophthalmology of Fattouma Bourguiba University Hospital of Monastir. Twenty‐one patients (42 eyes) were followed‐up for 12 months after the disease onset. The patients were included at the acute phase and subsequently treated. Sequential SS OCT changes were assessed. Results: Structural SS OCT changes occurred in 24 eyes (57.1%) on month 3 (M3), in 23 eyes (54.8%) on month 6 (M6), and in 19 eyes (45.2%) on month 12 (M12). They included external nuclear layer atrophy (14.3% on M3; 11.9% on M6; and 9.5% on M12); ellipsoid zone disruption (40.5% on M3; 38.1% on M6; and 33.3% on M12); interdigitation zone disruption (42.9% on M3; 40.5% on M6; and 33.3% on M12); and multifocal retinal pigment epithelium thickening (50% on M3; 45.2% on M6; and 31% on M12). No significant association between final visual acuity and external retinal layers alterations at any stage of the study was found. Stepwise analysis showed that the presence of serous retinal detachment at presentation was an independent factor for structural SS OCT changes on M3. Conclusions: After initial onset, SS OCT shows thinning of the outer nuclear layer, disruption of the ellipsoid and interdigitation zones, and multifocal retinal pigment epithelium thickening. Serous retinal detachment at presentation is an independent factor for structural SS OCT changes during the first year of the disease. [ABSTRACT FROM AUTHOR]

Purpose: To describe the pattern of acute retinal necrosis (ARN) syndrome in a referral center in Tunisia.Methods: Retrospective review of the charts of 12 patients (12 eyes).Results: Necrotizing retinitis involved >50% of the retina in 33.3% of eyes. Polymerase chain reaction on aqueous humor sample identified herpes simplex virus-1 in 4 eyes (33.3%) and varicella zoster virus in 3 eyes (25%), and was negative in 5 eyes (41.7%). All patients received intravenous acyclovir, followed by oral antivirals. Follow-up ranged from 6 to 16 months. Retinal detachment (RD) occurred in 3 eyes (25%), but no patient developed bilateral ARN. Final visual acuity was 20/200 or worse in 7 eyes (58.3%). Delay in diagnosis (p = 0.015), macular involvement (p = 0.045), development of RD (p = 0.018), and 25-50% of retinal involvement (p = 0.045) were associated with a worse visual outcome.Conclusion: ARN carries poor visual prognosis in Tunisia.

Purpose: To determine the frequency of occurrence of limited clinical features which distinguish patients with Vogt-Koyanagi-Harada (VKH) disease from those with non-VKH uveitis. Design: Comparative case series. Participants: We included 1147 patients. Methods: All patients with bilateral ocular inflammatory disease presenting to any of 10 uveitis centers in the 3-month period between January 1 and March 31, 2006 (inclusive), were asked to participate. The clinical and historical features of disease were obtained from the participants via direct interview and chart review. Patients were stratified based on whether they were diagnosed with VKH disease or non-VKH uveitis for statistical analysis. Main Outcome Measures: Presence or absence of various clinical features in the 2 populations. Results: Of 1147 patients, 180 were diagnosed with VKH disease and 967 with non-VKH uveitis. Hispanics and Asians were more likely to be diagnosed with VKH than non-VKH disease compared with other ethnicities. In acute disease, the finding of exudative retinal detachment was most likely to be found in VKH disease with a positive predictive value (PPV) of 100 and negative predictive value (NPV) of 88.4, whereas in chronic disease, sunset glow fundus was most likely to be found, with a PPV of 94.5 and NPV of 89.2. Conclusions: Numerous clinical findings have been described in the past as important in the diagnosis of VKH. The current study reveals that of these, 2 are highly specific to this entity in an ethnically and geographically diverse group of patients with nontraumatic bilateral uveitis. These clinical findings are exudative retinal detachment during acute disease and sunset glow fundus during the chronic phase of the disease.
