Improved Vision For An Improved Life

Understanding Glaucoma:

Glaucoma is a condition that results in slow progressive damage to the optic nerve, which sends information from the eye to the brain. Damage to the optic nerve leads to a slow loss of vision. Rick factors for glaucoma include elevated eye pressure, increased age, and previous ocular injury. The most important and most treatable risk factor for glaucoma is elevated eye pressure. Inside the eye, there is a constant production of fluid that normally flows out of the eye through a very small drain. In certain individuals, this drain can become blocked for various reasons. The result is an increase in eye pressure, therefore increasing your risk of glaucoma. Glaucoma affects an estimated 1 million Indians and is the second-leading cause of blindness in India.

Types of Glaucoma:

  • Open-Angle Glaucoma

Open-angle glaucoma occurs slowly as the drainage area in the eye becomes clogged. Pressure builds up when the fluid inside the eye is unable to drain. Side (peripheral) vision is damaged gradually. Open-angle glaucoma is the most common kind of glaucoma.

  • Closed-Angle Glaucoma

With closed-angle glaucoma, eye pressure builds up rapidly when the drainage area of the eye suddenly becomes blocked. Blurry vision, rainbow halos around lights, headaches or severe pain may occur with closed-angle glaucoma. This type of glaucoma is less common than open-angle and may cause blindness if it is not treated immediately.

What are the types of Glaucoma Surgeries available?

YAG PI

How is surgery performed?

A YAG Laser Peripheral Iridotomy (YAG PI) is performed almost exclusively for patients with narrow angles, narrow-angle glaucoma, or acute angle-closure glaucoma. Aqueous fluid is made in the ciliary body of the eye, which is situated behind the iris. The aqueous fluid primarily escapes the eye by flowing between the lens and iris of the eye and then drains via the trabecular meshwork, which is located in the angle of the eye (where the front clear cornea meets the iris, essentially). If the flow of aqueous fluid to the drainage angle is obstructed by a forwardly bowed iris, the patient is said to have narrow angles.

YAG PI involves creating a tiny opening in the peripheral iris, allowing aqueous fluid to flow from behind the Iris directly to the anterior chamber of the eye. This typically allows an opening up of the angle of the eye. The narrow or closed-angle thus becomes an open-angle.

What is the post-operation procedure?

The procedure itself is completed with the patient seated at the laser and requires no sedation. Topical Anaesthesia eye drops are instilled, a lens is placed on the eye to better control the laser beam. In general, only a few very brief episodes of slight discomfort are associated with this procedure. However, generally, there is no pain involved post-operatively. The entire procedure takes only a few minutes.

Trabeculectomy

How is the surgery performed?

Trabeculectomy is a surgical operation which lowers the intraocular pressure inside the eye (IOP) in patients with glaucoma. This is achieved by making a small hole in the eyewall (sclera), covered by a thin trap-door in the sclera. The fluid inside the eye known as aqueous humour, drains through the trap-door to a small reservoir or bleb just under the eye surface, hidden by the eyelid. The trap-door is sutured (stitched) in a way that prevents aqueous humour from draining too quickly. By draining aqueous humour the trabeculectomy operation reduces the pressure on the optic nerve and prevents or slows further damage and further loss of vision in glaucoma.

How does the surgery improve the condition?

Control of the eye pressure with a trabeculectomy will not restore vision already lost from glaucoma. Glaucoma is often caused by high pressure inside the eye. Trabeculectomy reduces eye pressure by draining aqueous humor from the eye.
