Study on Vep Changes in Patients With Type Ii Diabetes Without Retinopathy

Abstract

BACKGROUNDIn patients with diabetes neurofunctional changes occur much earlier than clinically detectable changes, detection of these changes will help us in early identification of diabetic retinopathy leading to a better management and prognosis. Aim-The aim and objectives of the study were to observe the pattern reversal VEP in a group of patients with Type 2 Diabetes Mellitus without Retinopathy and to correlate it with duration of Diabetes and HbA1c levels. MATERIALS AND METHODSThis prospective hospital based cross sectional study was undertaken in 40 patients with type 2 DM referred from the department of diabetology. 40 age and sex matched control subjects were taken from master health check-up attending our hospital. All patients underwent a comprehensive ophthalmic examination, and the pattern VEPs was recorded.
