A genome-wide association study has identified genetic loci related to primary angle-closure glaucoma, specifically those associated with ocular biometry and morphology. The study's findings are part of a broader effort to understand the genetic components of glaucoma, with other research identifying numerous risk loci for primary open-angle glaucoma and intraocular pressure. The cumulative research suggests a complex genetic landscape for glaucoma, with multiple loci contributing to the disease.
