Traumatic macular retinoschisis in infants and children.

PURPOSE

To provide detailed description of pediatric traumatic retinoschisis.

METHODS

The medical records of children with either abusive head trauma and traumatic macular retinoschisis seen at a single center from 1993 to 2006 were reviewed retrospectively. Clinical details were extracted from the record and photographic documentation. Evaluation regarding abuse excluded ophthalmology findings to avoid circular reasoning.

RESULTS

Of 134 patients with suspected abusive head trauma, 31 had retinoschisis. Mean age was 9 months. Of the 31, 22 (71%) offered a history of injury, and 9 (29%) were found unresponsive without history of injury; 6 were reportedly shaken. All patients had seizures, vomiting, and/or altered responsiveness. All had subdural hemorrhage, with cerebral edema in 17 (55%). In 10 (32%), there were findings of blunt force head injuries; in 4 of these there was no impact history. Retinal hemorrhages were present in all cases. Agreement between sidedness of retinoschisis and subdural hemorrhage was poor. Eleven patients had retinal folds, 3 of which had a hemorrhagic edge to the schisis. Nine patients had extracranial manifestations of abuse. Multidisciplinary team adjudications were as follows: of the 31 cases, 18 were suspicious for abuse, 11 were indeterminate, and 2 were possibly accounted for by accidental severe crush injury. Three children died, and 11 suffered neurological sequelae.

CONCLUSIONS

Traumatic retinoschisis in children is highly associated with subdural hemorrhage, neurologic symptoms, and poor outcomes. Even with a conservative approach to opinion formulation, traumatic retinoschisis was associated with likely abuse.
