Practical approach to medical management of glaucoma.

Primary open angle glaucoma (POAG) is usually a chronic, slowly progressive disease. At present, all resources are directed towards reduction of intraocular pressure (IOP), the only known causal and treatable risk factor for glaucoma, and medical management is frequently the first choice in most cases. With the introduction of innovative tools for early diagnosis and newer medications for treatment, decision-making in diagnosis and treatment of glaucoma has become more complex. The philosophy of glaucoma management is to preserve the visual function and quality of life (QOL) of the individual with minimum effects on QOL in terms of cost, side effects, treatment regime, follow-up schedules as well as socioeconomic burden. Our aim should be not to treat just the IOP, optic disc or visual field, but to treat the patient as a whole so as to provide maximum benefit with minimal side effects. In this article, we describe the scientific approach to medical management, mainly of POAG.
