Sudden elevation of venous pressure may cause a decompensation in the retinal capillary bed, with subinternal limiting membrane haemorrhages (Hg) that rarely may break through and become subhyloid or intravitreal 1. We report the histological findings of internal limiting membrane (ILM) peel in a case of Valsalva retinopathy.
