Characteristics of choroidal neovascularization in wet age- related macular degeneration by optical coherence tomography angiography
Abstract
Description the characteristics of choroidal neovascularization in wet age-related macular degeneration by optical coherence tomography angiography. Method: Prospective descriptive study on 28 eyes of 27 patients with exudative age-related macular degeneration from 10/2021 to 8/2022 at the Department of Ophthalmology - National Geriatric Hospital. Results : 28 eyes of 27 patients were included in the study, with 3 types of neovascularization: type 1, type 2 and type 3, in which choroidal neovascularization type 1 accounts for the highest rate (75%), followed by type 2 (21.4%) and type 3 (3.6%). Qualitatively, the neovascular shape has obvious shapes such as medusa (32,1%), seafan (28,6%), followedby the prune vascular tree (25%) andthe lowest was the disappearance of the surrounding capillary system (14,3). Quantitatively, the average neovascular area measured was 1.54±0.89 mm2, vascular density and perfusion density in the central area is lower than the inner area and in the total. Conclusions: OCTA provides detailed images of the qualitative and quantitative characteristics of the neovascularization with high reliability and safety allowing us to repeat the survey many times during the treatment follow-up.
