OCT angiography demonstrates retinal angiomatous proliferation and chorioretinal anastomosis of type 3 neovascularization
To report the OCT angiography findings of type 3 neovascularization.
Two cases (one each with retinal angiomatous proliferation and chorioretinal anastomosis) are reported, in which the conventional fundus fluorescein angiography and spectral-domain optical coherence tomography findings were inconclusive.
OCT angiography demonstrated flow within the abnormal anastomotic network and delineated the extent of the lesion with respect to the retinal layers.
OCT angiography enables a quick diagnosis of type 3 neovascularization by demonstrating a supranormal flow within the lesion and delineates the lesion within different retinal layers.
