||PURPOSE / AIM. The purpose of this study was to describe
the central corneal thickness (CCT) distribution in Beninese
population and determine its correlations with age, gender,
intraocular pressure (IOP) and refraction.
METHODS. A prospective study was conducted at military
teaching hospital of Cotonou on glaucomatous and non
glaucomatous patients after the informed consent. We
collected epidemiological and demographic data, status of
glaucomatous under treatment or not, refraction, IOP and
CCT measurements. Data were analyzed using SPSS 17 with
statistical threshold of 5%.
RESULTS. A total of 530 patients were recruited. They
consisted of 235 men and 295 women. The average age was
41.86±16 years old. The mean IOP was 16.01± 4.65 mm Hg,
CCT average was 533±38 microns. There are afterbivariate
analysis of the CCT with sex, a significant difference
between men and women (530±37µm for men against
537±39 µm for women p = 0.01). The CCT decreases with
age ranging from 560 ±50.85 µm between 10 and 19 years to
514.52 ±31 µm for 70 years and over, and a strong
correlation was observed between IOP and CCT.
CONCLUSION. The CCT is thinner in Beninese patients
especially in men. CCT decreases with age and is
significantly correlated with IOP.
