    Abstract:
    PURPOSE: To evaluate the efficacy of intravitreal ranibizumab with and without pneumatic displacement for the treatment of submacular hemorrhage secondary to neovascular age-related macular degeneration. METHODS: We retrospectively reviewed the medical records of 93 treatment-naive patients (93 eyes) with submacular hemorrhage secondary to neovascular age-related macular degeneration. All patients were treated with an initial series of 3 monthly intravitreal ranibizumab injections, followed by as-needed injections. For the patients treated with pneumatic displacement, expansive gas was injected at the time of the first ranibizumab injection. RESULTS: Mean submacular hemorrhage area was 8.2 ± 5.8 disk areas, and mean symptom duration was 8.2 ± 5.2 days at baseline. Twelve months into treatment, the mean logarithm of the minimum angle of resolution of best-corrected visual acuity of all subjects significantly improved from 1.19 ± 0.55 (20/309) at baseline to 0.96 ± 0.39 (20/182, P = 0.007) at 12 months. The mean central foveal thickness also significantly improved from 473 ± 223 μm at baseline to 279 ± 134 μm (P < 0.001) at 12 months. However, no significant difference in best-corrected visual acuity and mean central foveal thickness between ranibizumab monotherapy (58 eyes) and combination therapy groups (35 eyes) was observed at 12 months. CONCLUSION: Intravitreal ranibizumab injections with and without pneumatic displacement are viable treatment options for submacular hemorrhage secondary to neovascular age-related macular degeneration.
