Glaucoma / Trabeculectomy

About Glaucoma / Trabeculectomy

Glaucoma is a group of eye conditions that affect the health of optic nerve, which is vital for good vision. The nerve damage is often caused due to the high pressure in the eye. The most common reason of this pressure is overproduction of a fluid called aqueous humor. If the drainage system does not work properly, the fluid can't flow out at its normal rate and the eye pressure increases resulting in Glaucoma.

Glaucoma is treated by lowering the eye pressure (intraocular pressure). Depending on the patient’s situation and type of the glaucoma he/she has, there are different options for treatment. One of the options is called Trabeculectomy.

 

Trabeculectomy is the common non-lasik procedure to lower the pressure in the eye. During trabeculectomy procedure, a small hole is made in the wall of the eye and a flap is created over this hole to allow fluid to escape the eye.

 

Trabeculectomy is recommended if medical treatments or laser trabeculoplasty have failed to bring the eye pressure low enough. Drainage tubes, such as Ahmed valve, are another option to treat glaucoma.

 

Please note that, none of the mentioned treatments can cure the damaged caused by glaucoma. Thus, it is recommended to visit an ophthalmologist regularly to be able to recognize this decease on the early stages.

Before Glaucoma / Trabeculectomy

The patient meets the doctor before the procedure. Several tests and examinations will be performed such as testing for optic nerve damage, checking the areas of vision loss, and inspecting the drainage angle.  The doctor then let the patient know which type of glaucoma treatment is recommended.

 

  • Use the prescribed eye drops before the surgery
  • Avoid using blood thinning medications such as Aspirin, Warfarin and Clopidogrel
  • Let the doctor know if you are allergic to any medication

How is Glaucoma / Trabeculectomy performed?

Trabeculectomy surgery is often performed under local anesthesia. In some rare cases, general anesthesia is recommended too.

The eye will be numbed with anesthetic drops. A half thickness flap is then made in the sclera and dissected all the way to the clear cornea. A hole will be made by removing a block of scleral tissue and part of the trabecular meshwork and Schlemm’s canal. As the iris may plug up this hole from the inside, a piece of the iris maybe removed at this time which is called iridectomy. Then the surgeon sutures the scleral flap loosely back in place. The sutures will be released gradually within a couple of weeks.

 

The surgeon will then put a patch on the operated eye. However, in some cases, if the unoperated eye does not see well, no patch will be used for the operated eye.As the result of this procedure, aqueous humor drains into a filtering area on top of the eye, which is called “bleb”. Normally, the bleb is concealed behind the upper eyelid.

 

Please note, all patients need to be examined one day after surgery so a further visit to the hospital is required the following day.

Glaucoma / Trabeculectomy

Glaucoma is a group of eye conditions that affect the health of optic nerve and damage it due to the high pressure in the eye. Trabeculectomy is the common non-lasik procedure to lower the pressure in the eye and treat glaucoma.

Recovery procedure

Possible discomfort

Pain, swelling and even partially droopy eyelid are common after Trabeculectomy procedure.

Contact your doctor if you notice abnormal tearing, pus-like discharge, or increasing redness.

Post procedure care

  • Ask a friend or relative to accompany you at home after the surgery
  • Wear a shield at night for the first two weeks
  • Don’t drive up to 2 weeks
  • Sleep with your head elevated
  • Use the prescribed eye drops regularly
  • Don’t stop taking the prescribed drugs without consulting the doctor
  • Avoid strenuous activity during the early post-operative period (including swimming, tennis, jogging and contact sports)
  • Activities such as yoga that require head-down posturing should be avoided
  • Don’t wear contact lenses at least up to 6 to 8 weeks
  • Eat a healthy diet
