Glaucoma


Glaucoma is a condition that causes damage to your eye's optic nerve and gets worse over time. It's often associated with a buildup of pressure inside the eye. Glaucoma tends to be inherited and may not show up until later in life.

The increased pressure, called intraocular pressure, can damage the optic nerve, which transmits images to the brain. If damage to the optic nerve from high eye pressure continues, glaucoma will cause permanent loss of vision. Without treatment, glaucoma can cause total permanent blindness within a few years.

Because most people with glaucoma have no early symptoms or pain from this increased pressure, it is important to see your eye doctor regularly so that glaucoma can be diagnosed and treated before long-term visual loss occurs.

Glaucoma affects the field of vision, preserving central vision till late stage of disease. Hence it goes undetected in many patient till late in life.

“If you are over age 40 and have a family history of glaucoma, you should have a complete eye exam with an eye doctor every one to two years. If you have health problems such as diabetes or a family history of glaucoma or are at risk for other eye diseases, you may need to visit your eye doctor more frequently” says Dr. Smita Gupta who has extensive experience in treating glaucoma and is well versed with the techniques and has extensive experience to treat Glaucoma problems.

Types of Glaucoma

There are two main types of glaucoma :

Open-angle glaucoma.

Also called wide-angle glaucoma, this is the most common type of glaucoma. The structures of the eye appear normal, but fluid in the eye does not flow properly through the drain of the eye, called the trabecular meshwork.

Angle-closure glaucoma.

Also called acute or chronic angle-closure or narrow-angle glaucoma, this type of glaucoma is less common in the West than in Asia. Poor drainage is caused because the angle between the iris and the cornea is too narrow and is physically blocked by the iris. This condition leads to a sudden buildup of pressure in the eye.

Symptoms :

If you have any of the following symptoms, seek immediate medical care:

1. Seeing halos around lights

2. Vision loss

3. Redness in the eye

4. Eye that looks hazy (particularly in infants)

5. Nausea or vomiting

6. Pain in the eye

7. Narrowing of vision (tunnel vision)

Glaucoma can be treated with prescribed eye drops, laser surgery or microsurgery Microsrgery for glaucoma is called a trabeculectomy where a new channel is created to drain the fluid thus reducing intraocular pressure that causes glaucoma. For some patients a glaucoma implant is the best option. The only way to prevent or control glaucoma is if it is diagnosed and treated early.
