Optical Coherence Tomography Angiography in a Patient With Diabetes and Preretinal Neovascularization
A 39-year-old patient with type 2 diabetes (diagnosed in 1996) presented for an evaluation of bilateral proliferative diabetic retinopathy that had been treated previously with panretinal photocoagulation. His visual acuity was 20/25 OD. Examination by ophthalmoscopy showed scattered dot-blot intraretinal hemorrhages and an inferotemporal preretinal neovascular frond ( Figure , A). Optical coherence tomography angiography was also performed ( Figure , B).
