Preretinal hemorrhage preventing subretinal involvement in multilayer macular hemorrhages: coincidence or plausible relationship?

Abstract

Abstract Background To report four cases with interesting anatomical presentations of multilayer macular hemorrhages with preretinal hemorrhage possibly preventing subretinal involvement of the macular area. Cases presentation Observational study of four patients presenting with macular hemorrhages. Results Four patients with multilayer macular hemorrhage due to different causes, presented with a halo-shaped submacular hemorrhage coincident with the preretinal hemorrhage borders. After resolution, in all cases, the macular area underneath the preretinal hemorrhage was found to be spared. Conclusion We hypothesized that an extensive preretinal hemorrhage can exert a mechanical force pushing the subretinal hemorrhage towards the periphery, consequently protecting the macular area.
