Glaucoma is a multifactorial optic neuropathy in which there is an acquired loss of retinal ganglion cells at levels beyond normal age-related loss and corresponding atrophy of the optic nerve. Although there are many existing treatments, glaucoma is a chronic condition. The objective of this review was to assess the effectiveness and safety of dosage form and cost effective analysis with glaucoma. Development of new drug candidates and novel delivery techniques for treatment of ocular diseases has recently accelerated. Treatment of anterior-segment diseases has witnessed advances in prodrug formulations and permeability enhancers. Intravitreal, subconjunctival, and periocular routes of administration and sustained-release formulations of nanoparticles and microparticles, as well as nonbiodegradable and biodegradable implants to deliver drugs to the posterior segment of the eye, are becoming popular therapeutic approaches.
