Medical treatment of glaucoma in West Africa is often unsuccessful because of the cost of medications, disease severity and poor compliance. Surgical treatment is likely to be a more practical solution.

The purpose of this study is to compare the safety and efficacy of the Aurolab glaucoma drainage device against trabeculectomy with mitomycin-c in a prospective randomised surgical study.
