Dark adaptation in diabetes mellitus

Br J Ophthalmol. 1979 Aug;63(8):539-41. doi: 10.1136/bjo.63.8.539.


The effect of diabetes mellitus on the normal dark adaptation curve is investigated. It has been found that diabetic patients take longer to adapt and that their absolute thresholds are raised. The degree of elevation in the final threshold correlates with the duration of diabetes.
