Abstract

Sudden visual loss after general anesthesia is a rare and serious complication. Unilateral visual loss can be caused by an increase in pressure in the preretinal veins with subsequent rupture and hematoma formation. Our patient most likely experienced an increase in venous pressure as a consequence of temporarily increased intrapulmonary pressures during a sustained Valsalva maneuver shortly after tracheal intubation. Although surgical correction is available, in almost all cases, no specific therapy is required because the problem completely regresses spontaneously.
