Bilateral Choroidal Neovascularization and Angioid Streaks in β Thalassemia

To Report a case of bilateral choroidal neovascularization (CNV) and angioid streaks in a patient with b thalassemia.

A 41-year-old male, a known case of b-thalassemia, presented with the gradual decrease of vision from 3 months ago. The best corrected visual acuity was 8/10 in right and 3/10 in the left eye and Marcus Gunn was negative. In slit lamp examination, the anterior segment of both eyes was normal and in the posterior segment of both eyes, dark brown to red irregular bands radiating a few millimeters from a peripapillary ring was visible. There was an active CNV in the right eye and a CNV scar in the left eye. Intravitreal injection of bevacizumab was performed for the right eye.

Angioid Streaks can occur in patients with β thalassemia and one of the complications of angioid streaks is choroidal neovascularization, which can decrease vision.
