WHAT IS GLAUCOMA?
Glaucoma is an eye disease where fluid pressure within the eye rises and if left untreated, the patient may lose vision and even become blind. The disease usually affects both eyes but one may be more severely affected than the other.
TYPES OF GLAUCOMA
There are two main kinds:
Open-angle glaucoma: One of the most common types of glaucoma, also known as wide-angle glaucoma. It is caused by the slow clogging of the drainage canals, leading to increased eye pressure.
Angle-closure glaucoma: It is a less common form of glaucoma. It is caused by blocked drainage canals, causing a sudden rise in intraocular pressure. It is also linked to farsightedness and cataracts.
WHAT CAUSES GLAUCOMA?
Glaucoma is the result of high fluid pressure inside your eyes that happens when the liquid in the front part of the eye doesn't circulate the way it ideally should.
Usually, the fluid, known as “aqueous humor”, flows out of your eye through a mesh-like channel. If this channel is blocked, the liquid builds up, causing glaucoma.
Some other causes include - an eye injury, old age, myopia, diabetes, severe eye infection and inflammatory conditions.
The most visible and common symptoms of glaucoma are:
- Seeing halos like glows around lights
- Vision loss
- Blurred vision
- Redness in the eye
- Nausea or vomiting
- Severe eye pain
- Tunnel vision
DIAGNOSIS & TREATMENT
A complete eye exam will be able to diagnose glaucoma. This includes measuring the eye pressure, inspect the drainage angle, and examine the optic nerve, cornea and peripheral vision.
The goal of treatment is to improve the flow of fluid from the eye and reduce its production. In most cases, initial treatment includes eye drops but in severe conditions where drugs don't work, surgery may be an option to bring down the pressure inside the eye.
