Relationship between corneal sensitivity and diabetic retinopathy among diabetics attending a Nigerian Teaching Hospital.

Cornea sensitivity was significantly lower among diabetics with retinopathy compared to those without retinopathy. Also, the degree of cornea sensation loss among diabetics reduced significantly with severity of diabetic retinopathy. Larger validity studies need to be conducted to further assess the use of corneal aesthesiometer as a screening tool for diabetic retinopathy among non-ophthalmologists and other cadres of health workers.
