Importance: Primary open-angle glaucoma (POAG) polygenic risk scores (PRSs) continue to be evaluated in primarily European-ancestry populations despite higher prevalence and worse outcomes in African-ancestry populations.
Objective: To evaluate how established POAG PRSs perform in African-ancestry samples from the Genetics in Glaucoma Patients of African Descent (GIGA), Genetics of Glaucoma in Individuals of African Descent (GGLAD), and Million Veteran Program (MVP) datasets and compare these with European-ancestry samples.
Design, Setting, And Participants: This was a multicenter, cross-sectional study of POAG cases and controls from Tanzania, South Africa, Nigeria, Ghana, and the US.
Prcis: Patients' acceptance of glaucoma therapy was high overall in this study, but lower for surgery than for laser or medical therapy. Fear and cost were the leading reasons why patients declined recommended therapy and they were treatment-specific. Cost was the primary reason for declining medical and laser therapy, while fear was the most common reason for declining surgical therapy.

We conducted a genome-wide association study (GWAS) for POAG in 11,275 individuals of African ancestry (6,003 cases; 5,272 controls). We detected 46 risk loci associated with POAG at genome-wide significance.

This study evaluated the burden and manifestations of genetic eye diseases in children in Ibadan, Nigeria.
Methods: this was a hospital-based cross-sectional study in which new and follow-up paediatric eye clinic patients were recruited consecutively at the University College Hospital, Ibadan.
