  • Title: Repair of a late-onset filtering bleb leak using a corneal graft shaped with an excimer laser.
    Author: Mistlberger A, Biowski R, Grabner G.
    Journal: Ophthalmic Surg Lasers; 2001; 32(5):428-31. PubMed ID: 11563789.
    Abstract:
    A new method for repairing an area of late scleral necrosis and bleb leak after glaucoma-filtering surgery using mitomycin C (MMC) is described. In a 33-year-old female patient diagnosed with bilateral juvenile glaucoma, a bleb leak occurred 41 months after trabeculectomy with MMC in the left eye. A corneal stromal patch-graft shaped to the desired size using an excimer laser (Excimer-Laser-Corneal-Shaping-System, ELCS-S) was used to cover the scleral defect. This step was followed by water-tight closure of the conjunctiva. During the follow-up period of 12 months the leak remained successfully repaired and the intraocular pressure stayed between 8 and 14 mm Hg without medication. This technique that uses lamellar grafts of very large size should be considered when a surgical repair of a large leaking bleb is required, especially in cases with scleral tissue necrosis.
