Patients' Acceptance of Glaucoma Therapy in Sub-Saharan Africa.

ABSTRACT

PURPOSE: To determine the frequency at which patients newly diagnosed with glaucoma in sub-Saharan Africa (SSA) decline recommended therapy and to characterize the reasons for declining therapy. METHODS: This was a multicenter, cross-sectional study conducted on adult patients at the time of glaucoma diagnosis at 27 centers in 10 countries in SSA. Data collected from the diagnostic encounter included demographics, clinical glaucoma characteristics, treatment recommendations, patient acceptance of therapy, and reasons for declining therapy. RESULTS: Among 2,282 eyes of 1,198 patients offered treatment for glaucoma, initially recommended treatment was accepted in 2,126 eyes (93.2%). Acceptance of therapy varied with the nature of treatment offered, with medical therapy accepted in 99.2% of eyes, laser therapy in 88.3%, and surgical therapy in 69.3%. The most common reasons cited for declining therapy were fear (42.9%) and cost (41.7%); cost was the primary reason for declining medical and laser therapy, while fear was the most common reason for declining surgical therapy. Most patients declining laser or surgical therapy accepted medical therapy as an alternate therapy (98.1%). CONCLUSIONS: Patients' acceptance of glaucoma therapy was high overall, but lower for surgery than for laser or medical therapy. Most patients who declined laser or surgical therapy accepted medical therapy as an alternate therapy when offered. Educational interventions, sustainable incentives, and other approaches are needed to enhance patient acceptance of glaucoma therapy in this setting, particularly surgery when needed.
