Frequently Asked Questions
General Questions
It is a slowly progressive disease of the optic nerve (nerve of sight) caused most frequently by increased pressure inside the eye.
No, it is not.
Yes, it can. And that is why it should be detected earlier and treated earlier.
Normally the shape of the eye is maintained by a certain normal pressure inside the eye (10-21mm of Hg). This is maintained by a delicate balance of production of fluid inside the eye and it’s outflow. If by some reason there is obstruction to outflow of the fluid the pressure inside increases and over a period of time damages the optic nerve. Left untreated it can lead to blindness.
In the early stages of Glaucoma it may not be noticed (seen or felt) by you. It may be detected during the course of a routine check up. Some times the disease can be noticed by gradual reduction in vision especially in the peripheral field of vision. Acute glaucoma wherein the pressure inside the eye increases suddenly you may have sudden drop in vision, pain, redness, watering, and dislike for light. In such an event see your doctor immediately.
General Questions
Are there different types of Glaucoma?
Yes, there are, depending on the structural abnormalities of the eye.
Who is at risk of developing Glaucoma?
- Age more than 50 years.
- Positive family history of Glaucoma.
- Myopic (Minus no. glasses).
- Diabetes.
- Persons having sustained eye injuries in past.
What tests are performed to diagnose Glaucoma?
Tonometry (Checking intraocular pressure), Gonioscopy, Optic disc evaluation, Perimetry – (Visual field testing).
Is there a cure?
It is important to understand that once diagnosed Glaucoma can be effectively controlled by medication, Surgery. This only slows down the progression of the disease. One should not take it for granted that once the Intraocular pressure is controlled, the disease is cured. It is not so. Periodic eye examination at least once every 6 to 12 months is a must to keep a watch on progression.
