Quantifying Diplopia with a Questionnaire – Corrected Proof
Purpose:
To report a diplopia questionnaire (DQ) with a data-driven scoring algorithm.
Design:
Cross-sectional study.
Participants:
To optimize questionnaire scoring, 147 adults with diplopic strabismus completed both the DQ and the Adult Strabismus-20 (AS-20) health-related quality-of-life (HRQOL) questionnaire.
