Evaluation of Capillary Network Abnormalities in Branch Retinal Vein Occlusion by Optical Coherence Tomography Angiography
Journal Title: The Egyptian Journal of Hospital Medicine - Year 2018, Vol 72, Issue 2
Abstract
<span>Objectives: </span><span>Is to detect the vascular morphological changes in the two intra retinal; layers superficial network layer and deep network layer by optical coherence tomography angiography (OCT-A) in cases with acute onset branch retinal vein occlusion (BRVO).<br /> </span><span>Study Design: </span><span>An observational cross-sectional study in new Kafer El-Sheikh Ophthalmology Hospital. </span><span>Population: </span><span>This study included ten patients with (BRVO) of recent onset within the last three months. </span><span>Methods: </span><span>Demographic data such as age, gender, sex and hypertensive history were obtained. A detailed evaluation of cases including complete anterior segment evaluation and posterior segment evaluation was done. OCT-A and fluorescein angiography (FA) were used to study the vascular morphological changes in the (BRVO) area.<br /> </span><span>Results: </span><span>As regarding 5 disc area of retinal ischemia FA detected ischemia in 2 cases (20%), detected no ischemia in one case (10%) and was not able to evaluate ischemia in 7 cases (70%) compared to OCT-A, that detected the ischemia in the superficial capillary plexus (SCP)in 4 cases (40%), and detected no ischemia in 6 cases (60%), but it detected the ischemia in the deep capillary plexus (DCP) in 6 cases (60%) and detected no ischemia in 4 cases (40%).<br /> </span><span>Conclusion: </span><span>Our study demonstrated that OCT-A was superior to FA in detection of macular ischemia in cases with acute onset branch retinal vein occlusion (BRVO), macular ischemia detected in the DCP by OCT- A had stronger negative relation with V.A. than that of SCP. By OCT-A macular edema (ME) was present mainly in the DCP compared to SCP.<br /> </span>
