We have collected retinal image of 70 patients of different diabetic retinopathy stages including 30 normal data and 40 abnormal data in different stages.
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 [*].
