Abstract Details

Purpose:

To study the role of OCT-Angiography to detect retinal vascular and macular abnormalities in comparison to Fundus Fluorescein Angiography (FFA)

Setting:

Vitreoretinal department of a Tertiary eye Institute

Methods:

A prospective study was done in patients with AH. All patients underwent comprehensive eye examination, OCT-Angiography and FFA. AH is graded as grade 1 (optic disc and second order vessels are visible), grade 2 (optic disc and 1 order vessels are visible), grade 3 (optic disc is hazily seen) and grade 4 (no view of fundus).

Results:

: A total of 20 subjects (25 eyes) were included in the study. Mean age of the subjects was 61.8±5 years. Indications for investigations included ruling out Diabetic retinopathy in 20 eyes, macular abnormalities in 5 eyes (2 -Choroidal neovascular membrane (CNVM), 1- central retinal artery occlusion and one eye of IPCV). AH Grade 1 was seen in 8 eyes, grade 2 in 4 eyes, grade 3 in 11 eyes and grade 4 in 2 eyes. OCT-Angiography was able to detect and delineate neovascularization in DR cases in comparison to FFA in 2 eyes of grade 1 and grade 3 AH each. OCT-Angio was able to detect other DR changes like microaneuyrisms, capillary dropout and foveal avascular zone (FAZ) , CNVM complex in comparison to FFA. OCT-Angio could delineate more accurate FAZ morphology in a case of grade 4 dense asteroid hyalosis .

Conclusions:

OCT-Angiography as a noninvasive imaging tool could pickup various retinal vascular and macular abnormalities in subjects with all grades of AH in comparison to FFA.
