Background: Precise evaluation of Central Corneal Thickness (CCT) is crucial for both tracking the activity of corneal endothelial cells and detecting corneal disorders including keratoconus and Fuchs Endothelial Corneal Dystrophy. The aim of this work was to use pentacam to measure CCT and generate CCT maps in diabetic patients with and without retinopathy and contrast those with normal subjects.
Patients and methods: This comparative cross-sectional study was executed on 75 subjects. They were split into three equal groups: (Group A): diabetic patients without diabetic retinopathy; (Group B): diabetic patients with diabetic retinopathy while (Group C): non-diabetic individuals. All groups were subjected to pentacam to measure CCT and generate corneal thickness maps to compare CCT concerning different groups.
Results: A statistically significant difference was detected in CCT across the groups. Patients with diabetes who did not have retinopathy had CCT that was not significantly different from those who did. It has been demonstrated that patients with diabetes mellitus who have had the condition for more than ten years have a significantly higher mean CCT than those who have had it for less than ten years. CCT showed a positive correlation with age, RBS, haemoglobin A1c (HBA1c) and DM duration. A significant correlation was existed between CCT and period of DM.
Conclusion: A statistically significant variation was detected in CCT between diabetic patients and normal controls. Age, RBS, HBA1c, and the length of DM can all have positive correlations with CCT. |
