About

The study aims to compare the differences of ocular surface features in controls and patients with diabetes and dry eye syndrome, to thoroughly evaluate the ocular surface health of diabetics, and to find out the relationship between dry eye syndrome and diabetes

Full description

In this study, we perform a completely comparison of ocular surface characteristic including the Ocular Surface Disease Index (OSDI) questionnaire,tearfilm break up time(BUT),corneal fluorescein scores(CFS),Shirmer test,corneal sensitivity)among diabetic patients with DE, diabetic patients without DE, non-diabetic patients with DE and normal subjects and analysis of EGF, IL-17A, IL-1β, IL-8 and TNF-α in tears and their clinical correlations are also performed to investigate potential biomarkers for diagnosis of diabetic with DE.
