Bleb revision surgery is a procedure performed to correct complications from glaucoma surgery, specifically trabeculectomy, which involves creating a filtering bleb to help lower intraocular pressure (IOP). Over time, the bleb may become infected, obstructed, or fail to provide proper drainage, leading to increased IOP and potential damage to the optic nerve.

During bleb revision surgery, the surgeon may perform a series of techniques, including adjusting or repositioning the bleb, removing scar tissue, or replacing the bleb with a new one to restore normal fluid drainage from the eye. The goal of the procedure is to stabilize IOP and improve long-term glaucoma management.

Bleb revision surgery is often necessary for patients who experience complications from trabeculectomy or other glaucoma surgeries. It is a safe, effective option for improving IOP control and preventing further vision loss in glaucoma patients.
