All about trabulectomy

Trabeculectomy is a surgical procedure commonly performed to treat glaucoma, a condition characterised by increased intraocular pressure (IOP) that can lead to optic nerve damage and vision loss. The primary goal of trabeculectomy is to reduce IOP by creating a new drainage pathway for aqueous humour, the fluid produced within the eye.

This procedure is typically recommended for patients whose glaucoma cannot be adequately controlled with medication or laser treatments. During the surgery, the ophthalmologist makes a small incision in the sclera, the white outer layer of the eye, to create a flap. This flap allows aqueous humor to flow from the anterior chamber of the eye into a small reservoir, or bleb, created beneath the conjunctiva (the thin membrane covering the eye).

By facilitating this drainage, trabeculectomy helps lower IOP and protect the optic nerve from damage. The procedure is usually performed on an outpatient basis and can take about 30 to 60 minutes. Patients may experience some discomfort and blurred vision post-surgery, but these symptoms typically improve over time.

Recovery involves regular follow-up visits to monitor IOP and assess the healing process. While trabeculectomy can be highly effective, it is not without risks. Potential complications include infection, bleeding, and over-drainage, which can lead to hypotony (low IOP) and vision problems. Despite these risks, trabeculectomy remains a valuable option for managing glaucoma, particularly in cases where other treatments have failed.

With proper postoperative care and monitoring, many patients experience significant improvements in their IOP levels and overall eye health. Ultimately, trabeculectomy can play a crucial role in preserving vision and enhancing the quality of life for individuals living with glaucoma.
