TRABECULECTOMIES Meaning and
Definition
-
Trabeculectomies are a surgical procedure commonly performed to treat glaucoma, a group of eye conditions that lead to damage of the optic nerve and potential loss of vision. This procedure aims to reduce the intraocular pressure (IOP) inside the eye by creating a new drainage channel for the aqueous humor, the fluid that nourishes the eye.
During a trabeculectomy, the surgeon creates a flap in the sclera (the white outer layer of the eye) and removes a small portion of tissue from the trabecular meshwork, the drainage area of the eye. This allows the aqueous humor to bypass the clogged or blocked natural drainage channels and flow freely into a space beneath the conjunctiva, the thin tissue covering the front of the eye. The conjunctiva then forms a filtering bleb, a small raised area through which the excess fluid can drain.
Trabeculectomies are commonly performed under local anesthesia and require precise surgical skills. The procedure aims to reduce the IOP and halt or slow down the progression of glaucoma, thereby preserving vision. Postoperative care includes the use of antibiotic and anti-inflammatory eye drops to prevent infection and control inflammation. Regular follow-up visits with an ophthalmologist are necessary to monitor the success of the surgery and adjust medications if needed.
Overall, trabeculectomies have proven to be an effective treatment option for individuals with glaucoma, providing a pathway for proper drainage of fluid within the eye and helping to manage the intraocular pressure.

Etymology of TRABECULECTOMIES
The word "trabeculectomies" is derived from two main components: "trabeculo-" and "-ectomy".
1. Trabeculo- comes from the Latin word "trabecula", meaning a small beam or bar. In anatomy, trabeculae refer to small supporting structures in various tissues. In the context of the eye, trabeculae are found in the drainage system responsible for regulating the outflow of aqueous humor, a fluid that nourishes and maintains eye pressure.
2. -ectomy is a suffix of Greek origin, derived from the word "ektomḗ", meaning excision or removal. It is commonly used in medical terminology to indicate the surgical removal of a particular body part or tissue.
