title: Pediatric periodic alternating gaze deviation with midline cerebellar disease.
abstract: Periodic alternating gaze deviation is a rare eye movement disorder characterized by a horizontal eccentric gaze that lasts for a few minutes in one direction before reversing to the opposite direction with the cycle repeating itself. This report details the findings of an affected infant with cerebellar hypoplasia in the context of previously reported cases and supports the idea that the phenomenon typically is caused by cerebellar midline disease.
