What is Glaucoma

Glaucoma is often referred to as the "silent thief of sight," as in a vast number of cases, no noticeable symptoms or pain is experienced until vision loss occurs. Glaucoma is a group of diseases that damage the eye’s optic nerve and can result in vision loss and blindness. Early detection and treatment is crucial in protecting your eyes from serious vision loss. Studies conducted show that eye pressure is a major risk factor leading to optic nerve damage. Glaucoma can also develop without increased eye pressure and is called low-tension or normal-tension glaucoma. At first, open-angle glaucoma has no symptoms and causes no pain or impairment in vision. Glaucoma can develop in one or both eyes and vision loss is permanent and irreversible. There are several types of glaucoma such as normal tension glaucoma, closed angle glaucoma, open angle glaucoma, pupillary block etc.

Symptoms of Glaucoma Eye

No initial symptoms, but usually associated with pain, distorted vision and vision loss in later stages

Treatment for Glaucoma

Glaucoma eye drops often are the first choice over glaucoma surgery and can be very effective at controlling IOP. If your eye doctor feels you are a good candidate for glaucoma eye drops, you may be prescribed more than one type to achieve the best IOP control. Doctors use a number of different categories of eye drops to treat glaucoma. They either decrease the amount of fluid (aqueous humor) in the eye or improve its outward flow, and some do both. Sometimes doctors will prescribe a combination


  • This procedure is often used to treat open-angle glaucoma. In argon laser trabeculoplasty (ALT), a high-energy laser is aimed at the trabecular meshwork to open areas in these clogged canals. These openings allow fluid to bypass drainage canals and flow out of the eye.
  • In selective laser trabeculoplasty (SLT) a low-energy laser treats specific cells in the trabecular meshwork. Since it affects only certain cells without causing collateral tissue damage, SLT can potentially be repeated.
Laser Peripheral Iridotomy
  • Laser peripheral iridotomy is frequently used to treat angle-closure glaucoma, in which the angle between the iris and the cornea is too small and blocks fluid flow out of the eye. A laser creates a small hole in the iris to allow fluid drainage
  • Cyclophotocoagulation : This procedure is usually used to treat more aggressive or advanced open-angle glaucoma that has not responded to other therapies. A laser is directed through the sclera or endoscopically at the eye fluid-producing ciliary body. The procedure helps decrease the production of fluid and lower eye pressure. Patients often need multiple treatments.
  • Scatter Panretinal Photocoagulation: This laser procedure destroys abnormal blood vessels in the retina that are associated with neovascular glaucoma.
  • Trabeculectomy: During a trabeculectomy, a flap is cut in the white part of the eye (sclera), and a piece of trabecular meshwork is removed (eye tissue located around the base of the cornea), and a flap is sutured. This creates a new opening (a fluid bubble or bleb will form on the eye's exterior) through which the fluid (aqueous humour) flows and enters the bloodstream. The surgery is normally an outpatient procedure but may require a one-night stay in a hospital. It is performed one eye at a time, usually four to six weeks apart.
  • Peripheral Iridectomy: Eye doctors use this procedure for angle-closure glaucoma. A small section of peripheral iris is removed by incision, which allows fluid to drain more easily from the eye.
