Abstract
 
Purpose:
 

To develop a performance-based measure that is a practical, clinically-useful way of evaluating the ability to perform visually related activities of daily living.

 
Methods:
 

118 Patients with glaucoma, but without other ocular morbidity, completed a nine-item performance-based test (Assessment of Ability related to Vision -AARV) of visually related activities of daily living (modified from the validated ADREV[1-3]). All patients also completed clinical tests, including visual acuity, monocular and binocular visual fields, contrast sensitivity, stereopsis and the National Eye Institute’s Visual Functioning Questionnaire (NEI VFQ-25). AARV test includes: 1, Matching socks; 2, Recognizing facial expression; 3, Placing a stick into different sized holes; 4, Reading in reduced illumination; 5, Finding boxes; 6, Walking an obstacle course; 7, Detecting motion; 8, Telephoning; and 9, Recognizing street signs. Various combinations of 2, 3 or 4 of the separate items were analyzed to determine if the value of the full 9-item test would be adequately preserved in the compressed forms. Pearson correlation coefficients were employed to determine the correlation between the compressed data and the full data.

 
Results:
 

Several different combinations of two, three or four-item scores were significantly related to the total nine-item AARV score. (Table.1) The time required to perform these tests ranged from 4 to 13 minutes.

 
Conclusions:
 

Compressed forms of a comprehensive performance-based measure have sufficiently high correlations with the full 9-item test. The time required to complete these tests should allow them to be clinically useful.
