This research examines intraocular pressure (IOP) in patients at the EYE Center Ophthalmology Clinic in Conakry, Guinea. It is an observational, descriptive study of 148 patients, with IOP measured by Goldmann applanation tonometry. The study analyzes epidemiological data, IOP values, iridocorneal angle characteristics, and therapeutic strategies. Results indicate mean IOP is within normal range for most patients, with age but not sex associated with increased IOP. Pigmentation of the angle may be a risk factor for hypertonia, even when the angle is open.
