Optical coherence tomography angiography of extraretinal flat neovascularization in an eye with aggressive retinopathy of prematurity (ROP), and regressed extraretinal neovascularization following intraretinal bevacizumab treatment. (A) In an eye with aggressive ROP at 36 weeks PMA, OCT B-scans with flow overlay near the posterior pole superior to the optic disc along the superotemporal arcade showed vascular flow in the extraretinal neovascular tissue appeared flatter and over a wider retinal surface area compared to the extraretinal neovascular plaques. (B) The same eye was imaged at 47 weeks PMA following bevacizumab treatment at 36 weeks PMA. The preretinal neovascular tissue was regressed and marked reduction of vascular flow within the preretinal tissue. However, one larger retinal vessel was seen (arrowheads) retained in the preretinal tissue elevated from its original intraretinal location.
