colon; Retinal dialysis is often associated with trauma; however, as this report discusses, observation of a nontraumatic idiopathic form of retinal dialysis has been described. Idiopathic retinal dialyses may be caused by developmental or hereditary anomalies of the peripheral retina and may lead to occult retinal detachments which are often asymptomatic. Despite clinical observations suggesting the existence of a nontraumatic form of retinal dialysis, conclusive evidence establishing idiopathic retinal dialysis as a distinct pathologic entity is lacking. Complications of retinal dialysis, either idiopathic or traumatic, include retinal detachment and permanent vision loss. Comprehensive fundus examinations, which include scleral depression, are therefore critical in detecting silent retinal dialyses particularly when a history of trauma is reported. This report describes a case of retinal dialysis in a patient whose history is negative for antecedent trauma.
