Bilateral Prefoveal Sub-Internal Limiting Membrane Hemorrhage in Autoimmune Hemolytic Anemia

摘要

Severe anemia can cause multilayered retinal hemorrhages. A 65-year-old woman noted "red spheres" in the central vision of both eyes during a hospital admission for autoimmune hemolytic anemia. Examination revealed extensive multilayered retinal hemorrhages, including bilateral foveal preretinal hemorrhage. Spectral-domain optical coherence tomography localized the preretinal blood to the sub-internal limiting membrane (ILM) space. Various options are available for management of such hemorrhage, including observation for spontaneous resolution, YAG laser membranotomy, or pars plana vitrectomy with ILM peeling. In the authors' patient, the size of the sub-ILM hemorrhage spontaneously improved during the course of 1 month, with both subjective and objective visual improvement.
