“…9 Furthermore, in a study in which a group of 17 adults and older children of at least 8 years of age received surgery for untreated infantile esotropia, none demonstrated stereo fusion or stereopsis. 10 Maturation of binocular sensory function is nearly complete by 18 months of age but continues to be susceptible to change until at least 4 years of age. 11 Furthermore, Fawcett et al found that the adult binocular visual system is not hardwired and susceptibile to change throughout life.…”

Purpose: To evaluate the factors affecting improvement of stereopsis following successful surgical correction of childhood strabismus in adults. Methods: In a prospective study, consecutive patients with childhood-onset, comitant, horizontal, constant strabismus; stereoacuity of more than 480 seconds of arc in TNO stereo test (absent stereopsis in TNO); and who had successful postoperative alignment (within 10 prism diopters [PD] of orthotropia) were enrolled. Postoperative stereopsis testing was performed using the TNO stereo test at 3 months after surgery.Results: A total of 34 patients (20 exotropes and 14 esotropes) were included. The mean age at the time of surgery was 26.08 ± 10.53 years (range, 14-53 years). Stereopsis was improved in 8 of 34 patients (23.5%). Postoperative alignment had influence on improvement of stereopsis; 38.1% of patients who had orthotropia gained stereopsis, whereas none of patients who had horizontal heterotropia (esotropia or exotropia) of 10 PD or less gained stereopsis (p = 0.01). Misalignment of 10 years' duration or longer did not preclude the development of postoperative stereoacuity (p = 0.31). There was a statistically insignificant increase in improvement of stereopsis in nonamblyopic group (30.4%) compared with amblyopic group (9.1%) (p = 0.22). Also, there was a statistically insignificant increase in improvement of stereopsis in exotropes (35%) compared with esotropes (7.1%) (p = 0.1). The angle of preoperative deviation had no influence on improvement of stereopsis (p = 0.44). Conclusion: A postoperative correction of orthotropia was the only predictive factor for improvement of stereopsis in adults with childhood strabismus.

“…The mean age of 4.8 years in the converters is considerably older than the presumed critical period for the development of motor fusion. 4,5 Once it developed, motor fusion persisted in all patients for the duration of the study, even after the Bangerter foil was discontinued. The development of motor fusion in the converters was associated with a statistically significant decrease in their deviation, which was not seen in the nonconverters.…”

“…[1][2][3] It is generally believed that motor fusion develops during an early formative period and that, if this opportunity is missed, patients are unlikely to develop it when they are older. 4,5 This study began when the authors observed the development of motor fusion in patients treated part-time with the Bangerter foil for strabismic amblyopia who were thought to be outside that formative period. Bangerter foils are diffusing filters that can be used for the penalization treatment of amblyopia.…”

Background We have previously reported improvement in psychosocial scores after strabismus surgery on the patient-derived health-related quality of life (HRQOL) Adult Strabismus 20 (AS-20) questionnaire in adults with nondiplopic strabismus. Unexpectedly, we also found improvement in the function domain. The aim of the present study was to identify which specific aspects of function-related quality of life improved postoperatively. Methods We retrospectively identified non-diplopic adult patients with a history of childhood onset strabismus who underwent surgery and who had preoperative and 1-year postoperative AS-20 questionnaires (scored from 0 [worst] to 100 [best]). Change in scores for each item was evaluated using signed-rank tests. Results A total of 20 patients were included. Of the 10 function-related AS-20 items, 9 showed significant mean improvement postoperatively (improvement ranged from 12.5 to 32.5 points, all P < 0.05). Rasch-derived mean scores improved in both reading function and general function domains (71.0 to 86.5 and 66.4 to 87.5, respectively; both P < 0.0001). Specific areas of function-related benefit were concentration, depth perception, hobbies, strain, reading, stress, and worry. Conclusions We found specific function-related quality of life benefits after strabismus surgery in nondiplopic adult patients, particularly those with childhood onset strabismus.
