Visual Outcomes After Pneumatic Displacement for Submacular Hemorrhage Secondary to Neovascular Age-Related Macular Degeneration and Polypoidal Choroidal Vasculopathy
Abstract: This retrospective study evaluated the visual outcomes following pneumatic displacement for submacular hemorrhage secondary to neovascular age-related macular degeneration and polypoidal choroidal vasculopathy. Twenty-four patients presenting within 15 days of symptom onset with submacular hemorrhage measuring 2 to ≥ 6 disc diameters underwent intravitreal injection of 100% perfluoropropane gas (0.2 to 0.4 mL). Anti-VEGF therapy was administered after confirmation of the underlying etiology using angiographic imaging. Successful displacement of hemorrhage from the fovea was achieved in 85% of evaluable cases. At 6 months, visual acuity improved in 78.3% of patients, and 43.5% gained at least two lines of vision. Mild vitreous hemorrhage was the most common complication. Visual prognosis appeared to be associated with hemorrhage size, displacement success, macular scarring, and response to anti-VEGF therapy. Pneumatic displacement may be a useful treatment option for selected patients with recent submacular hemorrhage.
