Valsalva retinopathy associated with vigorous dancing in a discotheque.

Valsalva retinopathy develops in response to a Valsalva maneuver. Decreased visual acuity may be caused by preretinal hemorrhage, which is related to the fovea, or by vitreous hemorrhage. The hemorrhage usually clears spontaneously. A case of Valsalva maculopathy in a young, healthy boy caused by physical exertion while dancing at a club is described. Reduced visual acuity and premacular hemorrhage spontaneously resolved during the 5-month postoperative period.
