Objective: To develop a culturally adapted Italian version of the Amblyopia and Strabismus Questionnaire (A&SQ) Health Survey and to test its acceptability, reliability, and validity in patients with strabismus.
Study Design And Setting: The English A&SQ was translated into Italian after established cross-cultural adaptation procedures. The questionnaire was administered to 99 consecutive outpatients with strabismus and 39 normal adults and readministered after 2 weeks to 15 randomly selected patients and 26 adults with normal vision.
Purpose: To evaluate the dose-effect relationship for medial rectus muscle advancement in patients with consecutive exotropia.
Methods: Pre- and postoperative deviations 1 day and 6 months after surgery were measured by linear strabismometric method. The change in deviation (difference between preoperative and postoperative deviation at 6 months) was correlated to the surgical dose (dose-effect relationship) and the preoperative distance deviation by multiple regression analysis.
