Purpose: Subretinal hemorrhage is one of the most serious complications of exudative age-related macular degeneration (AMD). Treatment with vitreous surgery with or without plasminogen activator, fluid-gas exchange, or perfluorocarbon yields only a small improvement in visual acuity. Patients and Methods: The files of 24 patients with submacular hemorrhage secondary to AMD who were treated by injection of perfluoropropane gas (C3F 8) (11 patients) or sulfur hexafluoride (SF6) (13 patients) were reviewed for visual acuity before and after the procedure and time of treatment from onset of symptoms. Results: For the whole sample, pneumatic displacement led to a statistically significant improvement in mean visual acuity (p = 0.015). A significant difference between pre- and postoperative visual acuity was found for the patients treated with SF 6 (p = 0.034), but not for the patients treated with C 3F8 (p = 0.245). Conclusion: The use of gas injection to displace submacular hemorrhage can significantly improve visual acuity.
