Visual acuity outcome in patients with subretinal hemorrhage - office procedure vs. surgical treatment

Purpose To evaluate the effects of intravitreal injection of tissue plasminogen activator (tPA) and gas vs. pars plana vitrectomy (PPV) surgery as first-line treatment for subretinal hemorrhage. Methods Retrospective study of 107 adults treated for subretinal hemorrhage at a tertiary hospital during 2008–2019; 51 received injection of tPA and gas and 56 underwent PPV. Results No between-group differences were found in age and sex, medical history, use of anticoagulants or antiplatelets, history of ocular surgeries, and previous use of intravitreal anti-VEGF. Overall follow-up time was longer in the PPV group (median 4.9 vs 3.28 years, p = 0.005). The hemorrhage was displaced in a similar percentage of patients in the tPA-and-gas group (n = 40, 78.4%) and the PPV group (n = 45, 80.4%) (p = 0.816). Approximately 80% of patients in the tPA-and-gas group were able to forgo PPV surgery. Visual acuity (in LogMAR) was similar in the two groups prior to the diagnosis of subretinal hemorrhage but better in the tPA-and-gas group at the end of follow-up (p
