Abstract

Rwanda is a small but densely populated country, situated at the watershed between East and West Africa, close to the equator. The mean elevation is around 1500 m.

We studied 114 males (mean age 28.42 years) and III females (mean age 29.84 years) at the ophthalmological outpatient department of the Centre Hospitalier in Kigali. Changes to the eye caused by the climate were fewer than expected. Only 10 patients (5 males, 5 females) with pterygium (mean age 33.0 years), and four males and two females with climatic droplet keratopathy (mean age 47.5 years) were observed. However, the size of the pinguecula was marked.

Corneal thickness, measured with Haag-Streit's device, averaged 0.524 mm in 38 males and 0.521 mm in 38 females.

The Rwandans showed a normal chamber depth, a mean of 2.98 mm being noted in 107 males and a mean of 2.80 mm in 106 females.
