The optic nerve is made of more than a million tiny nerve fibers - like an electric cable made up of many small wires. As these nerve fibers die, you will develop loss in peripheral vision. You won't notice blind spots until most of your optic nerve fibers have died. If all of the fibers die, you will become blind.
Often, open angle glaucoma is hereditary, and the patient is asymptomatic until late in the disease process when poor peripheral vision becomes apparent. This is the most common type of glaucoma. It happens gradually, where the eye does not drain fluid (like a clogged drain). As a result, eye pressure builds and starts to damage the optic nerve. This type of glaucoma is painless and causes no vision changes at first.
Some people can have optic nerves that are sensitive to normal eye pressure. This means their risk of getting glaucoma is higher than normal. Regular eye exams are important to find early signs of damage to their optic nerve.
The disease is most commonly found among the elderly and those who have small eyes. Known as angle-closure glaucoma or narrow-angle glaucoma, this type occurs when an individual's iris is very close to the drainage angle in their eye. The iris can end up blocking the drainage angle. You can think of it like a piece of paper over a sink drain. When the drainage angle gets completely blocked, eye pressure rises very quickly. This is called an acute attack. It is a true eye emergency, and you should call your ophthalmologist right away or you might go blind.
Many people with angle-closure glaucoma develop it slowly. This is called chronic angle-closure glaucoma. There are no symptoms at first, so they don’t know they have it until the damage is severe or they have an attack. However, 1 out of 3 people (30%) with angle-closure will have a sudden blockage, causing an attack.
The only way to diagnose glaucoma is with a complete eye exam. A glaucoma screening that only checks eye pressure is not enough to check for glaucoma. During Glaucoma evaluation, your ophthalmologist will:
Due to long term use of these eye drops, they can cause minor side effects which can be noticed after a long time. They are:
Surgery can alleviate severe drainage issues by manually creating a new path or placing an implant. Surgical treatment is advised when pressure is not controlled medically. Glaucoma can be safely treated at Shiv Jyoti Eye Hospital using advanced surgical treatment options below:
