Trabeculectomy

Definition

Trabeculectomy is a surgical procedure used to treat glaucoma by creating an opening in the eye's trabecular meshwork to allow fluid to drain, reducing intraocular pressure. This helps prevent damage to the optic nerve and vision loss.

5 Must Know Facts For Your Next Test

1. Trabeculectomy is often considered when medications and laser treatments fail to control glaucoma.
2. The procedure involves creating a small flap in the sclera, the white part of the eye, and removing a piece of trabecular meshwork.
3. Postoperative care includes using antibiotic and anti-inflammatory ophthalmic drugs to prevent infection and control inflammation.
4. One of the common complications after trabeculectomy is bleb failure, where the drainage site becomes less effective over time.
5. Proper patient monitoring post-surgery is crucial for detecting any signs of infection or increased intraocular pressure.
