Abstract

Purpose : Whether strabismus surgery in adults is merely cosmetic is controversial. In this study, we evaluate the stereopsis and health-related quality of life (HRQOL) following successful surgical correction of childhood strabismus in adults.

Methods : In a prospective study, static and dynamic stereopsis was performed before surgery and one month after surgery. At the same time, Adult strabismus-20 (AS-20), and Amblyopia and Strabismus questionnaire (A&SQ) were investigated.

Results : A total of 16 patients (9 exotropes and 7 esotropes) were included. The mean age at the time of surgery was 25.75 years (range, 18-37years). 13 patients demonstrated nil stereopsis before surgery. One month after surgery, 4 patients (25.00%) gained improvement of stereopis and 4 patients (25.00%) achieved evident improvement of stereopsis. The latter were all exotropes (2 constant and 2 intermittent) with large angles (≥100 prism diopter (PD)). The bigger the angle of preoperative deviation, the better the postoperative stereopsis (F=5.666, P=0.017). The duration of misalignment(F=0.509, P=0.613), the beginning age of strabismus(F=1.021, P=0.388), and the postoperative alignment (F=0.776, P=0.480) had no influence on improvement of stereopsis. There was a statistically insignificant increase in improvement of stereopsis in exotropes compared with esotropes (x2=4.317,P=0.115). Also, there was a statistically insignificant increase in improvement of stereopsis in nonamblyopic group compared with amblyopic group (x2=5.333,P=0.069). Except functional score measured by A&SQ, all other HRQOL scores (composite, psychosocial and functional) measured by AS-20 and showed significant improvement after surgery (AS-20: t=4.294, P=0.001; t=2.346, P=0.033; t=5.871, P=0.000; AS&Q: t=3.840, P=0.002; t=6.804, P=0.000; t=1.559, P=0.140).

Conclusions : Nil stereopsis does not mean no hope for stereopsis in adults with childhood strabismus. They may also regain stereopsis after surgery, especially for those exotropes with large misalignment. Strabismus surgery can greatly increase their HRQOL.
