    Author: Lim JI, Drews-Botsch C, Sternberg P, Capone A, Aaberg TM.
    Journal: Ophthalmology; 1995 Sep; 102(9):1393-9. PubMed ID: 9097779.
    Abstract:
    PURPOSE: To determine whether pars plana vitrectomy combined with tissue plasminogen activator for evacuation of submacular hemorrhage results in improved visual acuity. METHODS: Retrospective review of 18 patients who received a subretinal injection of tissue plasminogen activator during a pars plana vitrectomy to evacuate dense submacular hemorrhages. RESULTS: Diagnoses included age-related macular degeneration (16 patients), ruptured macroaneurysm (1 patient), and penetrating ocular trauma (1 patient). Preoperative visual acuity ranged from 20/200 to counting fingers (median visual acuity, counting fingers). Follow-up ranged from 10 to 104 weeks (median, 33 weeks). Best postoperative visual acuity ranged from 20/30 to counting fingers (median, 20/300). Best postoperative visual acuity improved two or more lines in 11 (61%) of 18 eyes, remained unchanged in 4 (22%) of 18 eyes, and decreased two or more lines in 3 (17%) of 18 eyes (P = 0.10, Wilcoxon sign-rank test). Final visual acuity ranged from 20/40 to light perception (median, counting fingers). Final visual acuity improved two or more lines in 5 (28%) of 18 eyes, remained unchanged in 6 (33%) of 18 eyes, and decreased two or more lines in 7 (39%) of 18 eyes (P = 0.53, Wilcoxon sign-rank test). CONCLUSIONS: Pars plana vitrectomy to evacuate massive subretinal hemorrhage can improve visual acuity, but final visual acuity is limited by the underlying disease.
