We report the first description of temporalis fascia autograft to repair a late leakage bleb with scleral defect that occurred long time after trabeculectomy with mitomycin C.A 65-year-old woman was referred to our hospital with chronic late bleb leakage on her right eye. She had previously undergone a trabeculectomy with mitomycin C 3 years ago for a pigmentary glaucoma. Bleb leakage occurred 1½ year after the initial surgery. She underwent 2 surgical revisions consisting of a conjunctival advancement then an autologous conjunctival with partial scleral grafts without success. The initial best-corrected visual acuity of the right eye was 20/50 (Snellen scale). Slit-lamp examination revealed an avascular filtering bleb with leakage (massive positive Seidel test) and a scleral defect. The anterior chamber was deep and intraocular pressure (IOP) was 9 mm Hg.Faced with the risk of blebitis, endophthalmitis, and with the failure of the previous surgeries announced earlier, a surgical revision with autologous superficial temporalis fascia graft was decided to repair the leaking bleb. After local anesthesia, a sample of superficial temporalis fascia was harvested. The necrotic avascular conjunctiva around the bleb was dissected to separate and excise it from the sclera. The autologous fascia graft was sutured on the scleral defect with 10-0 nylon. Subsequently healthy conjunctiva was sutured above the graft.No bleb leakage occurred postoperatively, best-corrected visual acuity improved to 20/25, and IOP remained within normal levels 6 months after surgery without IOP-lowering medication.Superficial temporalis fascia autograft seems to be an effective, safe, and easy technique for ophthalmologists. It is a new procedure in the management of late-onset bleb leakage.
