We report a patient with postkeratoplasty glaucoma that developed a large, filtering bleb following trabeculectomy with intraoperative antimetabolite treatment. The hypotony and the bleb were managed using argon laser photocoagulation. A 26-year-old female patient underwent penetrating keratoplasty in the left eye for keratoconus. Postoperatively, her elevated intraocular pressure could not be controlled medically, and the patient underwent a trabeculectomy with intraoperative antimetabolite application. Two months later, hypotony maculopathy, optic disc edema, and choroidal folds developed, and her vision dropped. Steroid treatment and soft contact lenses did not help. Photocoagulation was applied twice to the surface of the bleb and the surrounding area. After the photocoagulation therapy, the patient's vision improved, intraocular pressure increased, and the optic disc edema and macular folds had resolved. Argon laser photocoagulation applied to a large filtering bleb associated with hypotony maculopathy is a useful treatment for bleb remodeling and elevating intraocular pressure.
