Fundus Fluorescein Angiogram Photographs of Diabetic Patients
This pages includes fundus fluorescein angiogram photographs of diabetic patients who were enrolled in a study in Isfahan University of Medical Sciences Persian Eye Clinic (Feiz Hospital). The size of the fundus images is 576 × 720 pixels (in jpeg format with 8-bit depth). We have collected retinal image of 70 patients of different diabetic retinopathy stages including 30 normal stage and 40 abnormal stages (including mild non-proliferative diabetic retinopathy (NPDR), moderate NPDR, severe NPDR and proliferative diabetic retinopathy (PDR)). At the screening visit, a comprehensive ophthalmic evaluation was performed and included a medical history, applanation tonometry, slit-lamp examination, dilated fundus biomicroscopy, and ophthalmoscopy. The severity of diabetic retinopathy was diagnosed at the preoperative visit using slit-lamp funduscopic biomicroscopy and classified as either no retinopathy, mild NPDR, moderate NPDR, severe NPDR and PDR based on the International Clinical Diabetic Retinopathy Disease Severity Scale [*].
