Tear glucose is associated with the presence and severity of diabetic retinopathy.

ABSTRACT:

Purpose

To examine the association between tear glucose (TG) and the presence and severity of diabetic retinopathy (DR) in patients with type 2 diabetes mellitus (T2DM).

Methods

A cross-sectional study. TG was examined by rapid qualitative test strip in 160 patients. The severity of DR was graded as mild DR and severe DR. The presence and severity of DR were compared between patients with positive and negative TG. The association of TG with the presence and the severity of DR was estimated by multivariable regression analysis and spearman's rank correlation test, respectively. The performance of TG to detect DR was evaluated by the receiver operating characteristic (ROC) curve.

Results

In this study, 160 patients were included, with a median age of 64.0 years, and 88
