Functional outcomes after exotropia surgery
Reviewed by Fiona Rowe

The authors used the Chinese version of the AS20 and A&SQ questionnaires to explore if successful postoperative alignment could significantly improve health related quality of life (HRQOL) in adults with childhood large angle exotropia. They further evaluated the relationship between stereoacuity and HRQOL. This was a prospective study of 34 consecutive adults with >90PD exotropia from childhood. Mean age at surgery was 29.38 ±8.78 years. Success rates were 94.75% in intermittent exotropia and 73.33% in constant exotropia. At one month postoperative, stereoacuity improved in all but 10 patients. Binocular measurements were better in intermittent than constant exotropia with more achieving normal stereoacuity in the former. Quality of life scores for both questionnaires were significantly improved. The results suggest strabismus surgery improves stereoacuity and quality of life in these patients and surgery for these patients is not purely ‘cosmetic’

Does successful surgical correction of childhood large angle exotropia in adults make any difference to binocularity and quality of life?
