What is Glaucoma?
Glaucoma is a disease in which your optic nerve (nerve that transmits visual information to the brain) is damaged because of changes in the pressure inside your eyes. It may be of 2 kinds: Open Angle (chronic) and Angle Closure (Acute).
Glaucoma is the second leading cause of vision loss in the world. Increased pressure inside the eye (IOP) leading to damage of the optic nerve responsible for carrying image to the brain is the main cause of glaucoma.
Don’t let Glaucoma Darken Your Life
Glaucoma can take you sight before you know it.
What causes it?
The passages in your eye that normally drain the fluid out of your eyes become clogged. This pent-up fluid now raises the pressure in your eye and on the optic nerve causing damage and hence loss of vision. An injury, infection or tumor in or around your eye can also cause the pressure to rise. The following factors put you at risk:
- Having a family history of glaucoma.
- High blood pressure or other diseases of the blood vessels.
- Long term Steroid use.
- Above the age of 40 years.
What are the symptoms?
- Heaviness or a headache.
- Gradual darkening at cuter edge of vision.
- Appearance of colored rings around lights.
- Pain and redness in eyes.
GLAUCOMA TREATMENT STRATEGIES
The primary strategy for treatment is reducing IOP Data show the importance of reducing IOP Preservation of visual fields with aggressive treatment to reach target IOP
Preservation of optic nerve health addressing pressure-independent pathophysiologic mechanism involved in neuronal death
What are the treatment options?
Treatment varies depending upon your type of glaucoma. You will be prescribed eye drops or oral medications to reduce your eye pressure. You may also be advised to undergo a surgery or a surgery called trabeculectomy where changes are made in your eyes that help the fluid to escape out.
Family of ocular diseases characterized by progressive optic neuropathy and visual field loss
- Progressive retinal ganglion cell loss
- Gradual optic disk cupping
- Associated visual field deficits
Elevated intraocular pressure (IOP) is no longer included in the definition.
Risk Factors for the Development and Progression of Glaucoma
- Elevated IOP
- Family history
- Advanced age
- Genetic factors
- Extreme Nearsightedness
Diagnosis and special testing
- Intraocular pressure measurement
- Optic nerve assessment
- Gonioscopy evaluation
- Visual fields
- Nerve fibre analysis
- Lower eye pressure with eye drops
- Argon or selective laser treatment
Remember: with glaucoma, time is the enemy. So don’t wait. Talk to your doctor today and schedule a comprehensive eye examination

What are my chances of recovery?
If you have open angle glaucoma, proper treatment greatly decreases your risk of vision loss.
If you have angle closure glaucoma and it is neglected, you can become blind in that eye in 2 days or less. Timely treatment can return your vision to almost the previous level.
How will I know that my glaucoma treatment is working as I don’t have any symptoms?
Your eye doctor will examine your eyes to keep a check on your glaucoma and prevent any further damage. That is why routine checks are so important.
Does any particular diet help?
No, there is no evidence to prove that following a particular diet will treat or prevent glaucoma.
If I have a high eye pressure, does it mean that I have glaucoma?
No, a high eye pressure without any optic nerve damage only means that you are at a greater risk for glaucoma and that you should undergo routine examinations.
On the other hand, you can also develop glaucoma without having high eye pressure.
Can glaucoma be cured?
No, there is no cure for glaucoma and the vision loss due to the disease cannot be restored. Treatments available can stop further damage. Low vision aids can help you make the most of your remaining vision.
