Proliferative diabetic retinopathy (PDR) is one of the most severe complications of diabetes and, if left untreated, can lead to significant visual impairment. The disease typically presents with neovascularization and vision loss secondary to retinal ischemia. However, in rare cases, advanced-stage diabetic retinopathy may be detected by fundus fluorescein angiography (FFA) even in patients with normal visual acuity and no ophthalmic complaints. In this article, we present a case of proliferative diabetic retinopathy identified through advanced imaging in an asymptomatic patient with largely normal visual acuity and ophthalmological examination.
