The AGLT is a prospective, multicenter, randomized study in which adult black Africans with
treatment-naive open-angle glaucoma are assigned to therapy with selective laser
trabeculoplasty (SLT), medications provided at no cost (MED), or medications provided by
prescription for subjects to obtain at their own expense as per usual care (RX). The overall
goal of the AGLT is to determine the best treatment strategy for newly-diagnosed open-angle
glaucoma in Africa.
