Abstract

Purpose

To report the OCT angiography findings of type 3 neovascularization.

Methods

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.

Results

OCT angiography demonstrated flow within the abnormal anastomotic network and delineated the extent of the lesion with respect to the retinal layers.

Conclusion

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.

Keywords
