Advanced Glaucoma Surgery
What is Glaucoma?
Glaucoma is a complicated disease in which damage to the optic nerve leads to progressive, irreversible vision loss. Glaucoma is the second leading cause of blindness. Glaucoma damage may be caused by raised eye pressure or a weakness in the optic nerve. Your eye needs a certain amount of pressure to keep the eyeball in shape so that it works properly. The eye contains a clear watery fluid that circulates within the eye and gets drained away through drainage channels known as the ‘trabecular meshwork’. In the normal eye, the amount of fluid produced and the amount being drained is equally balanced. However, in glaucoma this balance is upset and causes the intraocular pressure to rise. It is this rise in pressure that damages the optic nerves. The amount of damage there is depends on how high the pressure is and how long it lasts, and whether there is a poor blood supply or other weakness of the optic nerve.

Risk factors for Glaucoma:
The goal of glaucoma treatment is to decrease the pressure in the eyes. This is achieved using special eye-drops or medications. Surgery is recommended if medications don’t yield the desired result, or with an aim to prevent further vision loss or blindness.
Depending on your particular situation, surgical options include:
