Trabeculectomy is a surgical procedure performed to treat glaucoma by reducing intraocular pressure (IOP). In this surgery, the surgeon creates a small drainage channel (or flap) in the sclera to allow excess aqueous humor to flow out of the eye into a filtering bleb under the conjunctiva. This bypasses the eye’s natural drainage system, lowering IOP and preventing further damage to the optic nerve. Trabeculectomy is usually recommended when medications and laser treatments fail to control eye pressure. With proper postoperative care, it can significantly slow or halt the progression of glaucoma.

• Purpose: To reduce intraocular pressure in glaucoma patients.
• Indication: When medicines and laser therapy are ineffective.
• Effect: Lowers IOP, reduces risk of optic nerve damage.
• Anesthesia: Usually local.
• Benefits: Effective long-term pressure control.
