Glaucoma Treatement

Chronic Open Angle Glaucoma

The most common type of glaucoma, known as chronic open angle (COAG) or primary open angle, occurs when the canals draining the eye of aqueous humor become clogged. This blockage can gradually increase pressure within the eye to damaging levels. No pain occurs, so individuals are usually unaware that these changes are occurring. There are no early signs or symptoms but over the years vision will be lost starting in the periphery and moving towards the central vision.

Acute Angle Closure Glaucoma

When eye pressure builds up rapidly, it is called acute angle-closure glaucoma. This type of glaucoma commonly occurs in individuals who have narrow anterior chamber angles. In these cases, aqueous fluid behind the iris cannot pass through the pupil thus pushing the iris forward, preventing aqueous drainage through the angle. It is as though a sheet of paper floating near a drain suddenly drops over the opening and blocks the flow out of the sink. In cases of acute angle closure glaucoma, one may experience blurred vision, halos around lights, deep pain behind the eye, nausea, and vomiting. Nethradhama advises its patients to have periodic eye examinations for early detection of glaucoma.

High pressure alone does not mean that you have glaucoma. In  Nethradhama we put together many kinds of information to determine your risk for developing this disease. The most important  risk factors include:

• Age (Over 40 years)
• Near-sightedness (Myopia)
• A family history of glaucoma
• Past injuries to the eyes
• A history of severe anemia or shock
• Diabetes/ Hypertension

The glaucoma specialist will weigh all of these factors before deciding whether you need treatment for glaucoma, or whether you should be monitored closely as a  glaucoma suspect. Being glaucoma suspect means your risk of developing glaucoma is higher than normal, and you need to have a regular examination to detect the early signs of damage to the optic nerve.

There is no cure. However, Glaucoma can be controlled if detected early. Appropriate and timely treatment goes a long way in either slowing down or halting the progression of the disease.
