Valsalva Maneuver - Valsalva Retinopathy

Valsalva Retinopathy

A pathologic syndrome associated with the Valsalva maneuver is Valsalva retinopathy. It presents as preretinal hemorrhage (bleeding in front of the retina) in people with a history of transient increase in the intrathoracic pressure. The bleeding may be associated with a history of heavy lifting, a forceful coughing, straining on the toilet, or vomiting. The bleeding may cause a reduction of vision if it obstructs the visual axis. Patients may also note floaters in their vision. Usually a full recovery of vision is made.
