RESUMEN
PURPOSE: Glaucoma encompasses a particular set of degenerative diseases of the optic nerve which may have predisposing genetic factors. The objective of this study was to determine the prevalence and phenotypes of primary glaucoma encountered in the population. METHODS: This was a cross-sectional study carried out on retrospective data from three healthcare centers in the city of Ouagadougou between 2012 and 2020. Data collection was carried out using patient records. RESULTS: The population receiving diagnostic glaucoma examinations in the 3 healthcare centers during the study period consisted of 13,378 patients, of which 50.55% were female. The general prevalence of patients with primary glaucoma was 4.04% (or 540 patients). Primary open-angle glaucoma (80.37%), congenital glaucoma (15.74%) and primary angle-closure glaucoma (3.89%) were identified in the study population. CONCLUSION: Glaucoma is a public health problem in Burkina Faso. It is often diagnosed in the late stages because of its insidious progression. In a developing country, effort must be also made to equip and increase the number of healthcare centers. In addition, efforts must be made to raise awareness, and to develop and popularize molecular biologic techniques for early detection in order to provide patients with appropriate care.

INTRODUCTION: Central corneal thickness measurement permits an evaluation of physiological and pathological corneal changes. It allows for an intra-ocular pressure correction factor. Our purpose was to determine the mean central corneal thickness in children aged 0 to 72 months and to examine factors that might affect it. PATIENTS AND METHODS: This was a cross-sectional hospital study which took place from February to December 2019 in the ophthalmology service of YO University Medical Center. It included healthy eyes of children 0-72 months of age examined under general anesthesia. Ultrasonic pachymetry was used to measure the central corneal thickness. The studied variables were age, sex, CCT, corneal diameter, intraocular pressure, and cup/disc ratio. RESULTS: One hundred and twenty-seven healthy eyes of 78 children 0-72 months of age were included. The mean age was 22 months. The overall mean CCT was 554.01±34.21µm. It was 556.58µm for children from 0 to 36 months of age and 536.12µm for subjects over 36 months. The mean CCT was 555.96±32.96µm in boys and 551.80±36.16µm in girls. In patients who underwent bilateral CCT measurement, the mean CCT was 554.74±35.67µm in the right eye and 549.76±24.08µm in the left eye. Lower IOP's were found in patients with thicker corneas (p=0.00). CONCLUSION: The CCT values for black children over 36 months of age was similar to the CCT in black adults.
