Trabeculectomy: Creating a New Pathway for Vision Health
When glaucoma begins to damage the optic nerve due to increased eye pressure, one of the most effective surgical interventions is a procedure called trabeculectomy. This surgery is often recommended when medications or laser treatments aren’t enough to lower intraocular pressure.
What is Trabeculectomy?
Trabeculectomy is a surgical procedure that creates a new drainage pathway for fluid (aqueous humor) to leave the eye. By making a small flap in the white part of the eye (sclera) and a reservoir under the upper eyelid, excess fluid bypasses the blocked natural drainage system and reduces pressure inside the eye.
Why It’s Done
Glaucoma can lead to permanent vision loss if pressure within the eye isn’t controlled. Trabeculectomy is performed to:
- Prevent further optic nerve damage
- Lower intraocular pressure
- Preserve remaining vision
What to Expect
The procedure is typically done under local anesthesia. Most patients return home the same day, but post-operative care is crucial. Follow-up appointments are needed to monitor healing and ensure the new drainage path remains open.
How Effective Is It?
Trabeculectomy has been a gold standard in glaucoma treatment for decades and can significantly delay or prevent vision loss in advanced cases.
