AIM: To analyze dry eye conditions of type 2 diabetes and its related factors.

METHODS: Totally 45 patients(90 eyes)with type 2 diabetes and 40 patients(80 eyes)non-diabetic patients were chosen for this study. Tear film break-up time, Schirmer test, and corneal fluorescein staining differences between indicators and its related factors were analyzed.

RESULTS:In diabetes group, the mean tear film break-up time was 6.23±2.36s, significantly shorter than that of the control group; Schirmer infiltration experiments average length of filter strips was 8.65±3.82mm, significantly lower than that of the control group; corneal fluorescein staining score was 1.89±1.31points, significantly higher. The incidence rate of dry eye was 58%, was significantly higher, the difference had statistically significant(P<0.05). The results of Logistic Multivariate analysis showed that basal secretion of tear volume and tear film break-up time were risk factors for type 2 diabetic patients with dry eye.

CONCLUSION: In type 2 diabetes patients, the tear film breakup time is shortened, and the basal tear secretion is decreased corneal fluorescein staining score increased.Basal secretion of tear volume and tear film break-up time was risk factors for type 2 diabetic patients with dry eye.
