Background: The prevalence and causes of corneal blindness vary from one region of the world to another. There is even variation within the developing countries of Africa.
Method: A retrospective review of 675 patients with corneal scarring out of the 3,753 new patients corneal scarring in patients attending the eye clinic of the University College Hospital (UCH) Ibadan over a 5year period.
Results: Subjects in age groups 0 to 10years and 21 to 30years were mostly affected. Males were more affected with a ratio of 3:1. Most presentations were in the months of January to March and July to September. Almost half (48.99%) of the patients had uniocular blindness and no case of bilateral blindness from corneal opacity was found. The main causes of corneal opacity were trauma (51.1%) and microbial keratitis (26.70%) both of which are avoidable causes of blindness. No case of trachomatous corneal scarring was found in the group studied.
