Purpose: Ataxia-telangiectasia (A-T) is an autosomal recessive disorder characterized by progressive neurological deficits, including prominent oculomotor dysfunction. We report 5 cases of eye movement assessment in children 9-15 years old with A-T.
Methods: Three different oculomotor tasks (gaze holding, visually guided saccades and visual search) were used, and video-oculography was performed.
