Glaucoma is a disease which leads to a damage to the optic nerve which causes progressive and irreversible vision loss. Glaucoma is the second leading cause of blindness all around the Globe and mostly affects people over the age of 60 Years.
1. OPEN-ANGLE GLAUCOMA
Also called as Primary Open-angle GlaucomaThis is the most common form of glaucoma, chronic open-angle glaucoma is an outcome of a pressure build-up in the eye which leads to severe vision loss without showing any noticeable symptoms of the same. Its exact cause is still a mystery.
2. ACUTE CLOSED-ANGLE GLAUCOMA
Acute Closed-angle Glaucoma also called as an acute attack is completely opposite of that of Chronic Open-angle Glaucoma as its occurrence is sudden and very painful. It can cause severe damage and lead to permanent loss of vision in a short span of time.
3. SECONDARY GLAUCOMA
Secondary Glaucoma occurs as a result of something else apart from internal pressure which including the following:
i. Previous medical conditions.
Glaucoma can be treated with eye drops, pills, laser surgery, traditional surgery and a combination of all of these methods depending on its severity.The loss of vision from glaucoma is irreversible and the ultimate goal of any treatment is to prevent the loss of vision. Glaucoma can be treated if diagnosed at an early stage.
A) Trabeculectomy :
it is a surgical procedure done to relieve and stabilize the Intraocular pressure by extracting out a part of the eye’s trabecular meshwork and adjacent meshwork.The surgery helps in controlling the leaking fluid from the eye, which percolates under the conjunctiva. The surgery produces a valve where the same conjunctival bubble appears at the junction of the cornea and the sclera.
B) Implants for Glaucoma : Shunts and Stents are small devices in a shape of a tube made of plastic, metal or fabric that are inserted into the eye surgically to increase the outflow of intraocular fluid and reduce the high eye pressure. The stent helps in reducing and stabilizing the pressure in the eye. The devices create an alternative passageway to relieve obstructions and keep the passage open for the aqueous to escape from the eye by creating a separate passage to bypass the damaged part of the eye where the drainage occurs which leads to reduce and stabilise the pressure on the eye.
