OT tx for visual filed use color strip on side to cue field limit; worksheet to practice scanning; cues to scan visual field; reduce clutter; awareness of light & safety concerns
OT ideas for oculomotor control practice tracking, provide vestibular movement such as swinging
restorative ideas for ideational/ideomotor apraxia provide lots of sensory input - tactile, proprioception, auditory, guide, be consistent, educate family, offer cognitive cues like color
