In advanced glaucoma when
medications and/or laser surgery are unable to lower the eye pressure
to a safe level it may become necessary to perform a surgical procedure
in the operating room call a trabeculectomy. This
procedure creates a new "trap door" passage for fluid
to be drain out of the eye [see image at right]. This alternate
route for drainage lowers the eye pressure. New surgical techniques
utilize a medication called Mitomycin C which is applied to the
surgical site during the operation. The Mitomycin helps improve
the success rate of the surgery in cases that carry a greater risk
for failure.
After the trabeculectomy surgery, a fluid bubble forms under the
conjunctival covering of the eye. Fluid is absorbed by the conjunctival
vessels, thus lowering the eye pressure.
