The methods available for acuity assessment of multi-handicapped persons are limited by lack of verbal, manual and locomotor response indicators. However, eye activity itself, can provide a clue to what is seen. The results in the present study suggest that the preferential looking technique, using gratings as stimuli and eye movements as response indicators, is a useful tool for assessing the acuity of multi-handicapped people. However, acuity testing of multi-handicapped people was very time consuming, and called for many individual adaptations.
