Glaucoma there is a continuous balance between fresh production of liquid [aquous humor] and its drainage .When fluid is not drained out properly or fluid is produced too much then intra ocular pressure is raised .This harms the health of the eye. This causes ganglion cell and nerve fiber damage resulting into many signs of optic neuropathy.
It is a silent killer of sight. Without any pain, headache, difficulty in near and distance vision (contrary to common belief)
Type of glaucoma :
Treatment for glaucoma Unfortunately glaucoma can neither be prevented nor treated. But it can be controlled and further damage to the optic nerve can be slowed down or halted. This control can only be sustained through very disciplined and regular treatment as advised by the ophthalmologist. It is life long process. Even after surgery regular eye check up is necessary. In early stage one or two eye drops are sufficient. In later stages number, frequency and concentration of eye drops increases . Generally the surgery is done early if glaucoma is not controlled properly with few and less toxic medications or patient is not taking medications due to poverty or carelessness. An emergency operation called as laser iridotomy may be required for the treatment of acute glaucoma. This creates a drainage hole in the iris to relieve the pressure build up. This technique can be performed by laser surgery without making an incision in the eye. Sometimes a surgery called Trabeculectomy is performed to control intra ocular pressure in which a new drainage channel or passage is formed for the fluid to exit, thus lowering the pressure in the eye. facts about Glaucoma.
