This has not borne out with threshold perimetry, which showed no substantive change after VRT.7 Much concern exists that subclinical saccades into the blind hemifield may explain the improvements noted in suprathreshold perimetry. The site is secure. Not only do OTs address the loss of motor and neurological impairments through the provision of interventions, they can advise on environmental modifications, so that people with visual deficits can use their functional vision to live safely and independently. Occupational therapy interventions focus on child development and participation in functional tasks, through the participation in daily occupations, as a therapeutic activity. We closed with recognition by our interviewees that more studies are needed to determine its efficacy. With such instruction alone, individuals who are aware of their deficit tend to adapt disorganized scan paths, often scanning excessively into their blind field and putting themselves at risk for missing obstacles in their intact field, and those who are unaware of their deficit are not inclined to scan at all.
