LOCATING AND CHARACTERIZING ANGIOID STREAKS WITH EN FACE OPTICAL COHERENCE TOMOGRAPHY

Retin Cases Brief Rep. 2017;11(3):203-206. doi: 10.1097/ICB.0000000000000329.

Abstract

Purpose: To characterize angioid streaks (AS) with en face optical coherence tomography (OCT).

Methods: Case report of a patient with myopia presenting with choroidal neovascularization secondary to AS. Swept-source en face OCT ability to image the streaks was compared with spectral-domain and swept-source B-scans as well as color and red-free pictures. A 48-year-old man with myopia presented with sudden central visual loss. Choroidal neovascularization secondary to AS was diagnosed and intraocular anti-vascular endothelial growth factor given with clinical and OCT features improvement.

Results: Angioid streaks were visualized as less dark than the overlying retinal and the underlying choroidal vasculature. En face OCT located the changes at the level of Bruch membrane. An AS was found to be interrupted by the choroidal neovascularization, what was not captured by other modalities.

Conclusion: En face OCT allows to assess the extent of changes in Bruch membrane and their spatial relationship to choroidal neovascularization.
