The condition is induced by looking with the affected eye only, is further aggravated by applying red filters to the eye and is corrected by blue filters. Not to be confused with the disequilibrium syndrome. Major features are the postural abnormalities manifested by unilateral displacement and sensory disturbancess in the form of altered perception. A wide variety of congenital abnormalities, including mental retardation, cerebral palsy, retarded motor development, and muscle hypotonia may be observed in most cases.
