Impact of early non-proliferative diabetic retinopathy on contrast sensitivity.
Al-Shifa J Ophthalmol Jul ;15(1):22-30.

This study was conducted to find out the impact of early Non-proliferative Diabetic Retinopathy (NPDR) on contrast sensitivity. All the cases and controls were checked for their contrast sensitivity with Pelli-Robson contrast sensitivity test chart, followed by mydriatic fundus examination. Contrast sensitivity in cases was well below that of controls, reason being DR. So, contrast sensitivity testing can be used as a potential screening tool in optometric practice for early Non-proliferative diabetic retinopathy.
