Abstract

Recent advances in glaucoma genetics hold potential for dramatically changing the clinical care of glaucoma patients. To date, 5 primary open-angle glaucoma genes and 2 congenital glaucoma genes have been mapped. As more glaucoma genes are identified, earlier diagnosis for glaucoma should become more readily available. Progress in molecular genetics holds considerable promise for both current and future therapy of glaucoma. Glaucoma classification will be tailored to each individual based upon that person’s family history, i.e. family glaucoma genotype. In the future, the optimum treatment for a specific glaucoma patient might rely on the knowledge of the phenotype of that person’s causal gene, without having to resort to ‘trial and error’. At this time, glaucoma treatment is restricted to lowering intraocular pressure. In the near future, with the knowledge of the pathophysiology caused by the defective glaucoma gene, more traditional drug treatments may be used to bypass the gene defect. Ultimately, gene therapy would replace the mutant gene with a normal one before visual loss has occurred as has been done with a model for retinitis pigmentosa, the retinal degeneration mouse.
