Suggested criteria for vision classification on the AAMD adaptive behavior scale

The AAMD Adaptive Behavior Scale for Children and Adults is an instrument designed to assess the degree to which an individual has adapted to his environment. While one item of the scale refers to vision, no criteria have been established to indicate degree of vision impairment on such a scale. Such criteria are suggested including a supplement which describes other visual functions. A method of assessing visual acuity in non-verbal or uncooperative patients is given.
