Glaucoma is one of the leading causes of blindness worldwide. The main characteristic features include optic disc cupping, visual field
loss, and in most instances a raised intraocular pressure. Primary open angle glaucoma accounts for nearly two thirds of all cases, while
angle closure glaucoma contributes the majority of the remainder. Screening for glaucoma is not cost-effective, and diagnosis of the
primary open angle type is usually an incidental finding during ophthalmological examination. Various treatment options, including
medical and surgical interventions are accessible in the management of glaucoma. This article contains a brief description on the
pathophysiology and focuses on the pharmacological options available in the treatment of glaucoma.
