Letter contrast sensitivity changes in early diabetic retinopathy

Stavrou, Eftyhia P. & Wood, Joanne M. (2003) Letter contrast sensitivity changes in early diabetic retinopathy. Clinical and Experimental Optometry, 86(3), pp. 152-156.

Abstract

PURPOSE: To investigate the discriminative ability of letter contrast sensitivity (CS) and visual acuity (VA) in detecting functional losses in participants with type 2 diabetes. METHODS: LogMAR VA and letter CS were measured on 20 type 2 diabetic and 24 age-matched control participants. The diabetic participants were sub-grouped according to the level of retinopathy present. RESULTS: Letter CS was able to distinguish those participants with and without macular oedema and those with no or minimal diabetic retinopathy from the control group, whereas VA was not. CONCLUSION: Letter CS may be used as an effective screening tool to assess damage to the visual pathway of diabetic participants both with and without clinically detectable signs.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
