Outline of Final Research Achievements

Visual functions in persons with severe motor and intellectual disabilities (SMID) were assessed by interprofessional collaboration. Conventional visual assessment revealed that it was able to perform a quantitative evaluation as the severity of their motor and intelligence level, that is, the Yokochi’s classification for SMID, is going to reduce. Infrared pupillography, non-contact eye-tracker and functional near-infrared spectroscopy (fNIRS) are a minimally invasive, and are benefit for the objective assessment of visual functions in persons with SMID. Especially, using eye-tracker, grating acuity based on the eye movement, the effect of longitudinal habilitation intervention by care staff upon fixation duration and the response properties of optokinetic nystagmus were analyzed quantitatively. Automatic measurement for width of the palpebral fissure has been developed in the analysis of commercially available video images of face. Its effectiveness was verified in persons with SMID.
