Treatment
Depending on the location and extent of the bleeding, valsalva retinopathy usually resolves within weeks to months, without any complications. Patients are instructed to avoid anticoagulant drugs and physical activities which cause increase in intrathoracic or intra-abdominal pressure. For a speedy recovery, sometimes Nd:YAG laser or argon laser membranotomy may be advised. History
Valsalva retinopathy was first described in 1972 by American ophthalmologist Thomas D. Duane. == References ==
