RESULTS: In both cases, OCT demonstrated two distinct membranes: a highly reflective band immediately above the premacular hemorrhage, corresponding to the internal limiting membrane, and an overlying patchy membrane with low optical reflectivity consistent with posterior hyaloid. CONCLUSION: OCT supported the clinical impression that the plane of premacular hemorrhage in Valsalva retinopathy is probably under ILM. Larger case studies are required to confirm this finding.展开更多
