Abstract Details
Purpose:
To assess the different check sizes of pattern visual evoked potential (PVEP) in
diabetic patients without retinopathy according to HbA1c levels and diabetes duration.
Setting:
Ankara Training and Research Hospital, Turkey.
Methods:
Fifty eight eligible patients with type 2 diabetes mellitus and 26 age and sex matched healthy controls were included in the study. Only the right eye of each patient was analyzed. All of the patients underwent a comprehensive ophthalmic examination, and the PVEPs were recorded.
Results:
There was a statistically significant difference in P100 latency in 1 degree check size, and in N135 latency in 2 degree check size between controls and patient groups which have different HbA1c levels. There were statistically significant, positive and weak correlations with diabetes duration and P100 latency in 7 minutes and 15 minutes checks sizes, and N135 latency in 15 minutes check size.
Conclusions:
It was showed that were prolongations in P100 latency only in 1 degree check size, and in N135 only in 2 degree check size in diabetic patients without retinopathy. There was statistically significant correlation between diabetes duration and P100 and N135 latencies in different check sizes.
