Abstract
Objective The aim of this study is to investigate the risk factors of diabetic retinopathy (DR) to examine the relationship between VEP and the onset of early DR.Methods In this study,patients with early DR are classified into four groups according to sub-stages of early DR,i.e,DR-0 stage,mild,moderate and severe non-proliferative diabetic retinopathy (NPDR).P-VEP examinations were performed in each group (n =20) and in 30 normal subjects for control.Results Compared with controlled group,the level of LP100 in DR-0,mildNPDR,moderate NPDR and severe NPDR is 109.2±28.7,104.8±32.9,112.4±38.7,and 106.5 ±39.6,respectively.It was not correlated with the severity of NPDR (r =0.147).AP100 was 11.6 ±4.51,12.1 ±3.79,11.3 ±5.26,and 10.9 ±6.21,respectively,and was not correlated with the severity of NPDR (r =0.214) either.Conclusion The LP100 and AP100 are both higher in NPDR patients,which is helpful to the early diagnosis.However,LP100 or AP100 is not correlated with the severity of NPDR.关键词
