PRCIS: Physicians were most likely to recommend primary medical therapy upon diagnosis of glaucoma. Laser therapy was underutilized where they were available. Physicians were more likely to recommend surgery in severe glaucoma, laser therapy in mild glaucoma, while recommendation of medical therapy did not depend on glaucoma severity. PURPOSE: To characterize treatment patterns for newly diagnosed glaucoma in sub-Saharan Africa (SSA). METHODS: This was a multicenter cross-sectional study of adults newly diagnosed with glaucoma at 27 eye care centers in 10 African countries. In addition to demographic and clinical data, physician treatment recommendations (medication, laser, surgery, or no treatment) were recorded. Statistical analyses were performed using STATA version 14.0. RESULTS: Data from 1201 patients were analyzed. Physicians were most likely to recommend primary medical therapy upon diagnosis of glaucoma (69.4%), with laser (13.2%), surgery (14.9%), and no treatment (2.5%) recommended to the remaining patients. All sites had medical therapy available and most (25/27, 92.6%) could provide surgical treatment; only 16/27 (59.3%) sites offered laser, and at these sites, 30.8% of eyes were recommended to undergo primary laser procedures. As glaucoma severity increased, the laser was recommended less, surgery more, and medications unchanged. Patient acceptance of medical therapy was 99.1%, laser 88.3%, and surgery 69.3%. CONCLUSIONS: Medical therapy for first-line glaucoma management is preferred by most physicians in SSA (69%). Laser therapy may be underutilized at centers where it is available. These findings underscore the need for comparative studies of glaucoma treatments in SSA to inform the development of evidence-based treatment guidelines and of programs to reduce glaucoma blindness in SSA. Strategic approaches to glaucoma therapy in SSA must address the question of whether medical therapy is the most optimal first-line approach in this setting.
