| Glaucoma is one of the leading causes of blindness in the world, especially for older people. However visual loss is preventable or stabilized with early diagnosis and treatment. |
| |
| Glaucoma is a condition of the eye where the optic nerve is damaged due to increased intraoccular pressure. Glaucoma results when the pressure within the eye is high enough to be detrimental to the normal functioning of the optic nerve fibres, some of which stop functioning. Non-functional nerve fibres result in a loss of retinal function in the area from where they originate, leading to defects in the field of vision. |
| |
| The disease is called the `sneak thief of sight´ because it is painless, symptom less and irreversible. Therefore, the person with glaucoma is usually unaware of it until much loss of vision has occurred. In fact, half of those suffering damage from glaucoma do not know it. Currently, damage from glaucoma cannot be reversed and if the entire nerve is damaged, blindness results. Early detection and regular treatment are the keys to preventing optic nerve damage and blindness from glaucoma. |

| Laser Surgery Treatment |
| |
| Lasers are usually used in one of three ways: |
- In open-angle glaucoma the draining angle itself is enlarged to control eye pressure.
- In angle-closure glaucoma the laser creates a hole in the iris to open up and improve the flow of aqueous fluid to the drain.
- In painful late-stage glaucoma medication or surgery do not control the pressure. The laser closes some aqueous fluid-producing areas in the eye and lowers the eye pressure.
