ABSTRACT

Glaucoma is neurodegenerative condition that affects the eye and is associated with increased intraocular pressure (IOP) & left untreated patients may gradually experiences visual field loss, their sight completely. It is cause of blindness around the globe. Glaucoma as a condition that causes progressive neuropathy in the optic field and is characterised by structural changes to optic nerve head or optic disk. It is caused by a number of different eye diseases that most cases produce increased pressure within the eye. The pathophysiology of glaucoma is not completely understood, but relates to retinal ganglion cell death. It can be classified as open angle glaucoma, which are usually conditions of long duration(chronic), or angle-closure(closed angle)glaucoma, which include conditions occurring both suddenly(acute)and over a long period of time (chronic). The glaucoma usually affects both eyes, but the disease can progress more rapidly in one eye than in the other. Glaucoma cannot be cured, but can be controlled, medications can lower the pressure enough to protect the optic nerve from future damage and possible loss of vision. Glaucomatous visual loss cannot be restored. If the intraocular pressure is reduced substantially, progressive visual loss may be prevented in a major cases.
