What is Glaucoma?

Glaucoma is a disease that damages the eye’s optic nerve. It usually happens when fluid builds up in the front part of the eye. That extra fluid increases the pressure in eye, damaging the optic nerve. The condition is a leading cause of blindness for people over 60 years old. But blindness from glaucoma can often be prevented with early treatment.

Glaucoma describes a group of conditions in which there is characteristic cupping of the optic disc with corresponding visual field defects due to retinal ganglion cell loss. It is a progressive condition and the most common cause of irreversible blindness worldwide. The two major categories of glaucoma are open-angle glaucoma and narrow-angle glaucoma/angle-closure glaucoma. The “angle” in both cases refers to the drainage angle inside the eye that controls the outflow of the watery fluid (aqueous) which is being produced inside the eye.

Open-angle glaucoma (OAG) is the most common form of the disease. The drainage angle formed by the cornea and iris remains open, but the trabecular meshwork is partially blocked. This causes pressure in the eye to increase gradually and damages the optic nerve. It happens so slowly that the patient may lose vision before they are even aware of a problem, while in the case of narrow-angle glaucoma, the structure inside the eye that allows fluid to drain normally from the eye (called the drainage angle) becomes restricted. Narrow drainage angles in the eye increase the risk of the drainage angle that gets blocked, resulting in a significant increase in eye pressure and risk of vision loss. If this occurs, narrow-angle glaucoma is usually called angle-closure glaucoma.

What are the major types of Glaucoma?

There are two major types of glaucoma, i.e., Primary open-angle glaucoma (POAG), and Angle-closure /glaucoma closed-angle glaucoma/narrow-angle glaucoma. The “angle” in both cases refers to the drainage angle inside the eye that controls the outflow of the watery fluid (aqueous) which is being produced inside the eye.

Primary open-angle glaucoma is the most common type of glaucoma that happens gradually, where the eye does not drain fluid as well as it should (like a clogged drain). Whereas, angle-closure glaucoma happens when someone’s iris is very close to the drainage angle in their eye.

Glaucoma is treated by lowering the eye pressure (intraocular pressure), and depending on the situation, management include prescription eye drops, oral medications, laser treatment, surgery or a combination of any of these.

There are several risk factors like age >60 years, genetic predisposition, certain eye characteristics (such as a pupillary defect, thin cornea, myopia), low educational status, smoking, African descent, and visual problems are associated with this indication and treatment pattern varies accordingly.

What is Glaucoma Diagnosis?

Although glaucoma is not a curable disease, early diagnosis and adequate treatment are effective in reducing or preventing further optic nerve (ON) damage. The difficulty of distinguishing between eyes without glaucoma and eyes with early or subtle glaucoma is widely acknowledged. Furthermore, there is no unanimous opinion on what constitutes the first signs of damage in glaucoma.

What is Glaucoma Treatment?

Glaucoma is a group of eye diseases that can cause vision loss and blindness by damaging a nerve in the back of the eye called the optic nerve. There is no cure for glaucoma, but early treatment can often stop the damage and protect the vision. Doctors use a few different types of treatment for glaucoma, including medicines (usually eye drops), laser treatment, and surgery.
