Background and aim: Diabetic retinopathy(DR) is one of the most common complications of long-standing diabetes mellitus(DM).Early detection of this complication in the preclinical stages by Visual Evoked Potential (VEP) may help formulate management strategies to preserve u motion bowling ball Vision.With this background in mind, we conducted a cross-sectional study to measure the VEP of patients with DM.

Materials and methods: The study was conducted on 30 patients with diabetes mellitus(1 & 11) having no neurological or ophthalmological complications attending the diabetic clinic of RG Kar Medical College, Kolkata.Their PR-VEP(Pattern Reversal VEP) was measured in both eyes.Different VEP parameters(P100 & N75 waves) were compared with 30 age and sex-matched healthy controls and were statistically co-related with nerve conduction velocity, duration of diabetes, and Hb1Ac.

Results: The P100 & N75 wave peaks medline remedy phytoplex protectant z-guard paste were significantly prolonged in diabetic patients compared to healthy non-diabetic control.Also, this prolongation was significant with the increasing duration of the disease.Conclusion: Our study demonstrates that VEP prolongation in ophthalmologically normal DM patients may serve as an important screening tool to pick up visual dysfunction in the early stages.
