Long-Term Favorable Visual Outcomes in Patients with Large Submacular Hemorrhage.

Submacular hemorrhage (SMH) has been reported to be toxic to the retina based on animal studies. However, observational studies of patients with neovascular-related SMH and those treated with intravitreal anti-vascular growth factor (anti-VEGF) therapy have shown many favorable visual acuity outcomes. We report two cases of neovascular-related SMH with ten or more years of follow-up. The first case was an 83-year old female with a history of nonexudative age-related macular degeneration in both eyes presenting with sudden decrease in vision (20/400) in her right eye due to a large SMH, treated with anti-VEGF therapy. Over the next following months, there was resolution of the hemorrhage and return of good visual acuity. At 10-year follow-up, visual acuity was 20/30 in the right eye. The second case was a 49-year old female with a history of presumed ocular histoplasmosis syndrome (POHS), presenting with sudden vision loss (20/400) in her right eye due to large, thick SMH. With observation and intermittent anti-VEGF therapy, there was resolution of the hemorrhage. At 30-year follow-up, visual acuity was 20/20 in the right eye.
