Optical coherence tomography angiography in retinitis pigmentosa

Acta Ophthalmologica (2017)

A. Hassairi Yousra Falfoul Khaled El Matri O. Ben Lassoued A. Chebil

Purpose The aim of this study is to describe macular vascular abnormalities in patients affected by retinitis pigmentosa using Optical coherence tomography angiography (OCT-A). Methods Patients with a clinical diagnosis of retinitis pigmentosa underwent 3 × 3 Swept Source OCT-A scans using a Swept-Source DRI OCT Triton (Topcon Corporation, Japan). Scans with artifacts were excluded. Retinal vascular supply was estimated at the level of the superficial (SCP) and deep (DCP) capillary plexus, choriocapillaris and choroid. Results Six patients (12 eyes) were included in this study. Five were females (83.33%) and the mean age was 28.66 years. Mean best corrected visual acuity was 0.5 ± 0.3 LogMAR. Two patients presented bilateral macular edema on Swept Source-OCT and showed focal dislocations in the vascular network at the level of the DCP on the OCT-A, corresponding to the serous intraretinal cysts displacing the vascular plexus and the neural tissue. Qualitative analysis of OCT-A at the macular area revealed a reduction of vessel density in the SCP and DCP. The DCP and especially the temporal area are more affected. Three patients (50%) showed an enlarged foveal avascular zone at the DCP level. Conclusions Using OCT-A, we have demonstrated reduction of vessel densities especially located in the DCP. This vascular depletion could be an early event in the disease, which eventually causes ischemia, tissue loss and affects the macular function. Morphological vascular evaluation in patients affected by retinitis pigmentosa allows better understanding the pathogenesis of this disease and can have direct therapeutic implications for the future practical management of retinal dystrophies.

Contribution of wide field angiography to diabetic macular edema

Acta Ophthalmologica (2016)

Purpose To evaluate diabetic macular edema in non proliferative diabetic retinopathy (NPDR) using a wide field fluorescein angiography. Methods In a retrospective study, consecutive wide‐field angiographs using the Heidelberg Retina Angiograph 2 with a contact lens system Staurenghi and SD‐OCT were performed in diabetic patients with non proliferative diabetic retinopathy. Results A total of 71 eyes in 39 diabetic, average age was 58 years (SD 12). Most of the patients had type 2 diabetes mellitus (92%) and average duration since diabetes diagnosis was 10 years. Mean HA1c was 7.4%. Distribution of NPDR severity was: mild NPDR in 6% of eyes, moderate NPDR in 21% and severe NPDR in 73%. Macular edema was found in 53%. A thicker retina was observed in eyes with peripheral non perfusion (353 vs. 254 μ m p = 0.006). Retinal non perfusion was associated with macular edema (97 vs. 76%, p = 0.01) and poor visual acuity (p < 0.001). Conclusions Diabetic macular edema seems to be strongly associated with peripheral retinal non perfusion. So treatment and management of diabetic macular edema may be reconsidered using either a targeted laser treatment in the area of retinal non perfusion or anti‐VEGF intravitreal injection.

Case Report: Swept-source Optical Coherence Tomography and Angiography Findings in Lipemia Retinalis

Optometry and Vision Science (2021)

SIGNIFICANCE Lipemia retinalis is a very rare ocular manifestation of severe hypertriglyceridemia. It is usually symptomatic and regresses after normalization of triglycerides levels. Early recognition is important to prevent ocular and life-threatening complications. PURPOSE This study aimed to report a case of marked lipemia retinalis secondary to type V hypertriglyceridemia assessed with swept-source optical coherence tomography (OCT) and OCT angiography (OCT-A), with follow-up after dietary lipid restriction. METHODS Observational case report of lipemia retinal findings on color fundus photography, swept-source OCT and OCT-A, initially and after triglycerides lowering. CASE REPORT A 32-year-old pregnant patient with gestational diabetes and a history of hypertriglyceridemia was referred for diabetic retinopathy screening. Fundus examination revealed bilateral milky-white discoloration of retinal vessels with a “salmon-colored” retina. Swept-source OCT and OCT-A revealed extremely hyperreflective and dilated retinal vessels and multiple high-flow retinal hyperreflective dots, corresponding to dilated retinal capillaries. Choroidal vessels were enlarged and engorged, and choriocapillaris layer appeared thickened and hyperreflective with dilated and tortuous capillaries. Serum triglycerides were very high (70.02 mmol/L). After 21 days of very-low-fat diet, it was lowered to 15 mmol/L. We noted a normalization of the clinical, structural, and vascular findings. However, peripheral retinal vessels remained hyperreflective, despite their clinical normalization. CONCLUSIONS Swept-source OCT and OCT-A were beneficial in assessing lipemia retinalis noninvasively and monitoring choroidal and retinal vascular changes. Lipemia retinalis signs regressed initially in the posterior pole, choroidal anomalies were first to resolve, and clinical normalization preceded tomographic resolution.
