Contribution of "en face" SD‐OCT in retinal and choroidal vascular abnormalities

Abstract

AbstractPURPOSE : To evaluate the retinal and choroidal aspect in retinal or choroidal vascular abnormalities using « en face » OCT images. METHODS : All the study patients underwent a complete ophthalmologic examination including biomicroscopic fundus examination, color photography, fundus autofluorescence, fluorescein angiography, indocyanin green angiography , B‐scan and « en face » SD‐OCT. RESULTS : A total of 11 patients with choroidal or retinal vascular abnormalities, 4 cases diagnosed with submacular choroidal varix, 2 cases of central serous chorioretinopathy with choroidal cavitations, 2 cases of retinal vein occlusion (RVO) with perivenular whitening and retinal ischemia, 3 cases of retinal arterial macroaneurysm were analysed. The B scan findings were correlated with the angiography findings as well as with the « en face » OCT scans. In all the cases the « en face » OCT providing a layer‐by layer view of the involved retina and choroid (with EDI mode: enhanced‐depth imaging). CONCLUSIONS : « En face » OCT imaging enables an easy analyse of the structural retinal and choroidal vascular abnormalities which are correlated with B scan OCT and angiography findings.
