Purtscher retinopathy in the battered child syndrome.

Purtscher retinopathy is a hemorrhagic angiopathy that occurs after sudden compression of the thorax. Virtually all reported cases have been in adults who have decreased visual acuity, retinal hemorrhages and exudates, and no other neurological signs. By contrast, in infants, hemorrhagic retinopathy is rarely benign, and generally is considered to indicate intracranial hemorrhage, usually an acute subdural hematoma. Two battered infants had seizures and associated chest injury. There were retinal hemorrhages and exudates, unaccompanied by clinically important intracranial hemorrhage. At follow-up, the hemorrhagic retinopathy had resolved without sequelae; development was normal, and seizures had not recurred. Purtscher retinopathy thus should be added both to the differential diagnosis of hemorrhagic retinopathy in infancy and to the list of physical signs suggesting child abuse.
