About

A low endothelial count with endothelial pump dysfunction can contribute to corneal stromal hydration and loss of vision that can only be reversed by corneal transplantation,so this research proposed to detect any corneal endothelial changes related to DM , its duration and control of diabetes.

Full description

To establish any correlation between endothelial changes , and the duration of diabetes, hemoglobin A1c (HbA1c) by using specular microscope to do morphological examination of corneal endothelial cells, makes the measurement of mean cell density (MCD), measurement of coefficient of variation (CV) in the cell size as well as hexagonal appearance of the cell. These parameters provide the functional status index of the corneal endothelial layer .
