Scoring: Each item receives points as follows:
No difficulty: 4 points
A little difficulty: 3 points
A moderate amount: 2 points
A great deal: 1 point
Unable to do: 0 points.
Do not score items if patients don't participate in the activity for a non-vision-related reason. (For example, they had never taken part in sports.)
Total the scores and divide by the number of applicable questions for a resulting average between 0 and 4. Multiply the average by 25. The range now is from 0 (vision prevents patient from doing all activities) and 100 (patient can do all activities without difficulty).
