Objective: To compare the central corneal thickness between patients with diabetic retinopathy and non diabetics. Study Design: A cross sectional study.
Place and Duration of Study: Lahore General Hospital Lahore, from 1st Dec 2015 to 31st May 2016.
Material and Methods: A cross-sectional study was conducted in the ophthalmology outpatient department of Lahore General Hospital. A total of one hundred and fifty subjects from different age groups were selected for the study. An ultrasound pachymeter was used to measure CCT. There were two groups for sample, 75 were patients with diabetic retinopathy and 75 of them were non-diabetic subjects.
Results: The diabetic patients had average central corneal thickness of value 554.93 ± 33.73 microns. The average central corneal thickness found in non-diabetic patients was 520.41 ± 26.06 microns. The diabetic patients showed an increased central corneal thickness as compared to non-diabetics. The result of this study was statistically significant (p=0.001).
Conclusion: The diabetic patients showed an increased central corneal thickness as compared to non-diabetic patients.
