A Comparative Study of Central Corneal Thickness and Intraocular Pressure in Diabetic and Non-Diabetic Patients Attended a Tertiary Health Care Centre

Background: Diabetes is a rapidly-growing global health problem with a significant effect on morbidity and mortality due to diabetes-related complications. Objective: The aim of this study is to determine the correlation between central corneal thickness (CCT), intraocular pressure (IOP) and diabetes in indian patients. Patients and Methods: This prospective case-control study was performed at the ophthalmic department of sree Balaji medical college and hospital. .100 subjects from different age groups were included in the study. An ultrasound pachymeter was used to measure CCT and GAT to measure IOP. The sample was divided into two groups, 50 of them were non-diabetic subjects, and 50 were diabetic patients. Results: Diabetics with PDR showed significantly higher IOP and CCT values compared to the non-diabetic group. IOP was significantly compared with CCT and with the duration of diabetes. Conclusion: The sample group with diabetics with PDR showed a significantly high IOP and thicker corneas when compared to the sample group with non-diabetics. These data highlight the importance of considering CCT measurements in diabetics for proper interpretation of IOP.
