Objective: To evaluate the characteristics of central corneal thickness (CCT) in glaucoma patients followed a military hospital in Rabat. Patients and methods: This is a retrospective study of glaucoma patients followed in the military hospital ophthalmology flap service between January and December 2018. All subjects underwent a complete ophthalmic examination that included measures of CCT with an ultrasonic pachymeter. Results: A total of 205 patients (123 men and 82 women) were included in this study corresponding to 410 eyes. The age of patients ranged between 19 and 79 years. The average central corneal thickness was 519.54 ± 27.52µm in the right eye and 520.71 ± 27.99 µm in the left eye. Comparing the CCT between men and women and between the right eye and the left eye the other hand finds no statistically significant difference. Thus, the average age of the patients was 50.74 ± 12.7 years, with a mean central corneal thickness of 520.12 ± 27.75 microns. Discussion and conclusion: Compared to the Caucasian patient, our glaucoma patients differ in the early glaucoma and the thinness of the cornea, and are close to black African patients. This may induce a potential error in the measurement of intraocular pressure in glaucoma patients where our interests of Forever correlate intraocular pressure with pachymetry.
