Abstract

To investigate the differentiating ability of psycho physical test which include contrast sensitivity function

(CSF), dark adaptation (DA) and best corrected visual acuity (BCVA) in detecting functional losses in diabetic

participants with and without retinopathy.In this cross-sectional study we examined 90 patients between June to December 2019 including 60 diabetic patients(30 with retinopathy and 30 without retinopathy in fundus photography) with 30 control non-diabetic subjects matched for age and sex. The diabetic participants were sub grouped according to the level of retinopathy (EDTRS classification).CSF was examined by means of pelli robson chart in each eye; DA was assessed with photostress test and BCVA by Snellen chart.Significant difference was observed in visual performance of diabetics with retinopathy compared to without. The findings suggested that appropriate combination of existing tests can be a useful method of improving screening accuracy in diabetic patients.
