    Abstract:
    PURPOSE: To evaluate the surgical outcomes of small-gauge vitrectomy with subretinal injection of recombinant tissue plasminogen activator (rt-PA) for a submacular hemorrhage caused by a ruptured retinal arterial macroaneurysm (RAM). METHODS: Non-comparative, consecutive case-series performed at two ophthalmological institutions. We examined 22 eyes of 22 patients with a submacular hemorrhage associated with a RAM but without a preretinal or sub-internal limiting membrane hemorrhage at the fovea. During 25-gauge vitrectomy, approximately 4000-8000 IU of rt-PA was injected subretinally, followed by the injection of air or 10 % sulfur hexafluoride as a tamponade. The patients maintained an upright position for 1 hour, then turned to a facedown position for 1 to 3 days. The best-corrected visual acuity (BCVA) and postoperative complications were evaluated. RESULTS: The average interval from the onset of symptoms to surgery was 8.4 ± 7.6 days, and the average size of the subretinal hemorrhage was 3.4 ± 1.0 disc diameters. The submacular hemorrhage was displaced from the foveal area in all eyes after 1 week. The mean baseline BCVA was 1.41 ± 0.41 logMAR units, and it improved to 0.91 ± 0.43 at 1 month and to 0.64 ± 0.45 at the final visit (P = 0.0001, P < 0.0001 respectively). A macular hole was detected intraoperatively in two eyes and postoperatively in two eyes, and both were closed by internal limiting membrane peeling or a second vitrectomy. CONCLUSIONS: Small-gauge vitrectomy with subretinal rt-PA injection and gas tamponade were effective in displacing a submacular hemorrhage associated with a RAM.
