Diabetic retinopathy (DR) is a severe microvascular complication of diabetes mellitus that affects the retina and can lead to visual impairment. Visual Evoked Potential (VEP) is a non-invasive technique used to evaluate the functional integrity of the visual pathway, particularly in individuals with diabetic retinopathy. This study aims to evaluate and compare VEP responses between diabetic retinopathy patients and healthy controls. Fifty diabetic retinopathy patients and fifty age- and gender-matched controls were included. VEP results showed significantly prolonged P100 and N135 latencies in diabetic retinopathy patients compared to controls, indicating delayed conduction in the visual pathway. These findings support the utility of VEP in the early detection of visual impairment in diabetic retinopathy patients, even before clinical symptoms manifest.
