Description

ABSTRACT

Objective: To determine the average central corneal thickness (CCT) of healthy adults in Sudan.

Methods: This is a cross-sectional study conducted in the ophthalmology clinics of Khartoum state ophthalmic Hospitals. 340 normal subjects from different ethnic groups were studied. An ultrasound pachymeter was used to measure CCT.

Results: The mean (±SD) age of the study population was 44.29 ± 15.18 years with average of 47 years (range: 20-79). The mean (SD) CCT measurements were 517.1853 +/-32.026 micrometers. There was no statistically significant correlation between CCT and other independent variables like age, sex. There was statistically significant correlation between CCT and ethnic groups. Conclusions: The average CCT values obtained in this study closely match those of the Australians and Japanese and differ from African American and Indians. Further studies would be needed to provide more information about the cornea in Sudanese population.
