    Abstract:
    PURPOSE: To evaluate the efficacy of recombinant tissue plasminogen activator (rTPA) and sulfur hexafluoride (SF6) in displacing submacular hemorrhage in patients who had scleral buckling procedures complicated by the development of submacular hemorrhage. Final visual acuity and complications of the procedures were evaluated. METHODS: Sequential intravitreal injections of 50 microg rTPA in 0.1 mL and 0.4 cc SF6 were performed in eight patients who showed submacular hemorrhage 1 day after a scleral buckling procedure. The fundus was checked daily for 3 days after the injection of TPA and gas, and then was followed every week for 1 month and then every 2 months. Patients were observed for at least 6 months. Visual acuity and the status of complications were evaluated. RESULTS: Submacular hemorrhage was totally or partially displaced extramacularly in all patients on the day after rTPA and SF6 injection. Vitreous hemorrhage was present in all patients. The retina was attached in all patients and no recurrent retinal detachment was noted. Visual acuity was improved at 6 months after treatment in all seven of the patients with macula-off retinal detachments compared to the preoperative visual acuity. The last patient who had a macula-sparing retinal detachment had decreased vision (20/25) at 6 months compared to preoperatively. CONCLUSIONS: Recombinant tissue plasminogen activator and SF6 injection is an easy procedure that is less complicated than and as effective as internal drainage in patients with submacular hemorrhage developing as a complication of scleral buckling procedures.
