Glaucoma is a group of disorders in which, fluid pressure within the eye increases to a level, causing irreversible damage to the vision (optic) nerve that connects the eye to the brain to transmit visual images. Damage to the optic nerve results in irreversible blindness if left untreated.
There are two major types of glaucoma:
I) Primary Open Angle Glaucoma (POAG) - This is the most common type of glaucoma and mostly asymptomatic. The damage occurs gradually.
II) Primary Angle Closure Glaucoma (PACG) - This type with hallow or closed angles of anterior chamber sometimes present with sudden onset of red and painful eyes and would lead to blindness if not treated immediately.
Congenital Glaucoma is known to occur in children born with malformations in the angle of the eye. It can be detected by symptoms such as large cloudy eyes, severe sensitivity to light and excessive tearing or watery eyes.

Glaucoma cannot be cured, but it can be controlled. Aim of treatment is to reduce eye pressure using eye drops and medicines. In few, laser treatment is given to open up the drainage area for the fluid. In much severe cases, conventional surgery is performed to create a new drainage path. For congenital glaucoma, surgery is recommended because the effects of eye drops in infants are unknown.
