Detection of Nonexudative Choroidal Neovascularization Secondary to Angioid Streaks Using Optical Coherence Tomography Angiography

Abstract

Purpose To present a case of nonexudative choroidal neovascularization secondary to angioid streaks in a patient with pseudoxanthoma elasticum. The lesion was monitored over an 8-month period with the use of optical coherence tomography angiography. Methods Case report. Results The neovascular tissue area increased by 0.160 mm2 over a period of 8 months without any sign of exudation seen on optical coherence tomography or fluorescein angiography. Conclusions To our knowledge, this is the first report of a nonexudative choroidal neovascularization secondary to angioid streaks. Given that once a patient with angioid streaks develops choroidal neovascularization in one eye there is a high risk of bilateral involvement within a short amount of time, optical coherence tomography angiography can prove a useful tool for monitoring such lesions over time.
