Glaucoma -A Eye Disorder Its Causes, Risk Factor, Prevention and Medication
Journal Title: The Pharma Innovation - Year 2012, Vol 1, Issue 1
Abstract
Glaucoma refers to a group of eye conditions that lead to damage to the optic nerve, the nerve that carries visual information from the eye to the brain. In many cases, damage to the optic nerve is due to increased pressure in the eye, also known as intraocular pressure. Glaucoma is a disease of the optic nerve that affects approximately 60 million people globally. It is the second most common cause of blindness, leaving an estimated 7.5 million people blind. In India it affects 11 million people, of which 1.5 million are blind. Glaucoma is a disease that is often associated with elevated intraocular pressure, in which damage to the eye (optic) nerve can lead to loss of vision and even blindness. Glaucoma is the leading cause of irreversible blindness in the world. Glaucoma usually causes no symptoms early in its course, at which time it can only be diagnosed by regular eye examinations and screenings with the frequency of examination based on age and the presence of other risk factors. Intraocular pressure increases when either too much fluid is produced in the eye or the drainage or outflow channels of the eye become blocked. While anyone can get glaucoma, some people are at greater risk.
