Abstract BACKGROUND: Trabeculectomy is indicated when medical management and laser treatment of glaucoma is ineffective in treating the progression of optic nerve cupping, visual field loss and raised intraocular pressures. Trabeculectomy lowers intraocular pressure by the creation of an artificial channel which filters aqueous humor out of the anterior chamber and into sub-Tenon’s space. The most common cause for bleb failure is subconjunctival fibrosis; therefore, antimetabolites are utilized in the procedure to inhibit wound healing so that the filtering bleb can work properly. One of the problems with antimetabolites like mitomycin is that it leads to the formation of a relatively avascular, thin bleb which is more prone to leakage and endophthalmitis.

CASE REPORT(S): This case report demonstrates a patient with primary open angle glaucoma who reported to the eye clinic with the complaint that his eyes watered continuously and made his pillowcase wet at night. He had undergone the trabeculectomy procedure ten years earlier and had very large, thin blebs with a positive seidel sign in his left eye at his first visit.

CONCLUSIONS: This poster will review the trabeculectomy procedure, the essential use of antimetabolites in the procedure and the risks associated with them. Treatment of bleb leaks include the use of aqueous outflow inhibitors, bandage soft contact lenses, ocular glue and if necessary, bleb revision.
