Glaucoma is one of the major causes of blindness throughout the world; mostly because patients come to consultation late. We performed a prospective study of the intraocular pressure, fundus and perimetry in 307 young Cameroonians (20 to 39 years old). Glaucoma was found in 5.8% of cases. This study shows that the disease appears early in black people and must be detected in patients under 40 years old.
