Trabeculectomy Surgery

Trabeculectomy is the most common eye surgery for glaucoma.

In this procedure the doctor will create a new hole or tunnel in the sclera near the cornea. This hole will connect the internal part of the eye( The Anterior Chamber ) to the external part of the eye ( The Subconjunctival space )

The outer part of the hole is covered by the conjunctiva. This hole will allow the aqueous humor to be directed outside the eye and decrease the volume of fluid inside the eye. This will help to lower the I.O.P.

This procedure is about 80 % effective in lowering I.O.P

As in all surgeries, this procedure has complications such as infections, inflammation, over drainage of aqueous humor, fibrosis or scar of the conjunctiva that surrounds the hole and decreasing in the amount of aqueous humor drained, cataract, retinal and Choroidal detachment.

With the application of antimetabolites drug intra-operatively, the risk of fibrosis or scar will decrease. The most common antimetabolites used are 5-fluorouracil and mitomycin C.

To decrease the risk of these complications, Patients should have regular follow up and should continue using the eye drops that the doctor prescribed.

If you notice any unusual symptoms like loss of vision or severe eye pain, you should visit your doctor or the emergency room as soon as you can.
