The objective was to describe the occupational performance in basic and
instrumental daily activities of persons living in the community who have
received comprehensive interdisciplinary low vision rehabilitation
services.
Method
The Mesure de l'impact de la déficience visuelle dans les activités
quotidiennes (a measure of the impact of visual impairment in daily
activities) was administered at home to 102 individuals who participated in
a comprehensive low vision rehabilitation program. Performance in 16
near-vision activities was measured with the person's aids and strategies;
nine more global tasks were questionnaire-based. Handicap scores were
obtained by multiplying performance × importance ratings.
Results
Average performance was satisfactory or very satisfactory for 21/25 items,
even if 92% of the participants had a moderate or severe visual impairment.
A severe or total handicap was present in at least one activity for 79% of
the subjects. The most handicapping activities required visual searches of
finely printed information on a complex or visually crowded document, or
shopping and mobility.
Conclusion
People with low vision who took part in a comprehensive rehabilitation
program generally face no or slight handicap situations in their basic and
instrumental daily activities. However, major handicap situations may remain
in some important activities.
