Improved sensory status and quality-of-life measures in adult patients after strabismus surgery

PURPOSE To evaluate the change in sensory status and quality-of-life measures in adults with long-standing childhood-onset constant strabismus. METHODS Consecutive patients with childhood-onset, long-term constant strabismus were enrolled. Sensory status was examined with Bagolini striated glasses test and Worth 4-dot test. Stereopsis was tested with the Lang and TNO stereopsis tests. Quality of life was studied with 2 different questionnaires (Short Form Health Survey [SF-36] and the Amblyopia and Strabismus Questionnaire [A&SQ]), which patients completed before and 3 months after strabismus surgery. RESULTS A total of 20 patients (age range, 18-63 years) were included, 10 of whom were esotropic and 10 of whom were exotropic. Of these, 13 obtained a satisfactory postoperative alignment and demonstrated an increase of sensory status with Bagolini striated glasses. Six patients who demonstrated suppression preoperatively achieved fusion and stereopsis post-operatively. The mean score in all domains of the A&SQ improved significantly, particularly with regard to social contact and cosmesis (P = 0.00067), distance estimation (P = 0.000312), and visual disorientation (P = 0.004777). Similarly, the mean score in 7 of 8 areas in the SF-36 improved significantly, particularly with regard to physical function (P = 0.000564), general health (P = 0.002296), vitality (P = 0.002891), social function (P = 0.004234), and mental health (P = 0.000334). The overall mean score of both questionnaires improved in all patients with a satisfactory postoperative alignment and increase of sensory status. CONCLUSIONS Surgical treatment of strabismus in adults with long-standing childhood-onset constant strabismus can result in patients feeling that their quality of life has improved and can restore binocular sensory function.
