PURPOSE: To evaluate vitrectomy with subretinal tissue plasminogen activator (t-PA) injection, and air tamponade, followed by intravitreal anti-vascular endothelial growth factor (VEGF) therapy for submacular hemorrhage in polypoidal choroidal vasculopathy (PCV). DESIGN: Prospective, interventional case series. METHODS: setting: Two clinics. PATIENTS: Fifteen eyes of 15 consecutive patients (mean age 72 ± 7 years) with submacular hemorrhage attributable to PCV. INCLUSION CRITERIA: PCV diagnosis with unorganized submacular hemorrhage greater than 500 μm thick. EXCLUSION CRITERIA: Submacular hemorrhage attributable to macular diseases (eg, high myopia, typical age-related macular degeneration, retinal angiomatous proliferation, and angioid streaks). INTERVENTION: Vitrectomy with 4000 IU t-PA injected subretinally and fluid/air exchange. Patients remained facedown for 3 days after surgery. Anti-VEGF drugs were administered as exudative changes required. MAIN OUTCOME MEASURES: Submacular hemorrhage displacement from the macula and changes in best-corrected visual acuities (BCVAs). RESULTS: Mean time from onset to surgery was 9.5 ± 4.5 (range, 5-21) days. Mean follow-up period was 9.4 ± 3.1 (range, 6-17) months. Surgery successfully displaced submacular hemorrhages from the macula in all eyes. Mean BCVA at baseline (0.98 ± 0.44) had improved significantly both 1 month after surgery (0.41 ± 0.25, P < .01) and at final visits (0.23 ± 0.25, P < .001). In all eyes, exudative retinal changes relapsed after surgery but were completely resolved by anti-VEGF injections. No complications occurred in any patients. CONCLUSION: Treating submacular hemorrhage with vitrectomy and subretinal t-PA injection, followed by intravitreal anti-VEGF therapy, is a promising strategy for improving visual acuity in PCV patients warranting further investigation.
