SURGICAL PROCEDURES

GLAUCOMA SURGERY

Glaucoma is a spectrum of diseases, that damage the optic nerve. There are numerous reasons for the optic nerve damage, the best understood is with regards to eye pressure.

A significant amount of eye pressure presses on to the optic nerve, thereby slowly damaging the one million tiny fibres that make up the optic nerve.

Where does this pressure come from?

  • Fluid is regularly produced in the Ciliary Body of the eye
  • Fluid regularly drains out through the pupil, into the ANGLE of the eye
  • In Glaucoma, more commonly, the angle structures for drainage are OPEN, but dysfunctional. But sometimes, the angle is physically CLOSED, therefore no drainage occurs
  • Congenital
  • Steroid eye drops

GLAUCOMA SURGERY

HOW DO WE TREAT IT?

Treatment depends primarily on determining if the angle is OPEN or CLOSED.

Open-Angle Glaucoma

Treatment is either medical, surgical, or often a combination of the two to reduce the number of topical medications required to control the disease.

Medical Treatment

There are numerous topical and oral medications on the market. Long-term medical treatment involves topical eye drops which have a number of side effects. It is therefore advisable to only be treated by an ophthalmologist, after a long-detailed understanding of the best type of treatment for you.

Surgical Treatment

Surgery varies from novel approaches that improve the current anatomical drainage system of the eye (called MIGS Minimally Invasive Glaucoma Surgery), to creating a new drainage pathway for the fluid to drain out of your eye.

Most glaucoma surgery has a high success rate for at least two years after treatment, thereafter, depending on your disease, further surgical or medical management may be required.

Closed-Angle Glaucoma

Treatment also involves medical and surgical management; however, surgery has the higher long-term success rate. Surgery involves mechanisms to open the angle of the eye for drainage for recommence naturally. Failing this, the creation of new drainage pathways may be explored.
