Visual disorders after traumatic brain injury in developmental age.

Visual disorders secondary to TBI are common, often multiple, associated with complex clinical pictures; in developmental age they may particularly interfere with the development process, and compromise the rehabilitation and outcome processes. The aim of this study is to identify visual disorders in 56 post-traumatic children admitted to the Traumatic Brain Injury Unit. All patients underwent a complete clinical, neurological and neuroophthalmological assessment. Correlations were studied between visual disorders and clinical parameters of acute phase, age at trauma, neuroimaging data and outcome, in order to identify possible risk factors for their occurrence. A high incidence was found of complex visual disorders following head trauma: decreased visual acuity, together with a convergence oculo-motor deficit, is the most frequently detected deficit. Trauma severity, indicated by duration of coma, is associated with most of the visual disorders and appears to be the main risk factor conducive to their appearance.
