“…16 However, in a study by Kassem and Elhilali, early surgical alignment of strabismus in patients with acquired esotropia was advisable to achieve stereopsis. 17 Also, in the period of visual maturation, early surgery minimizes the duration of misalignment and is associated with better binocular vision outcomes. 18,19 Stereoacuity can be improved with treatment of amblyopia.…”

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.

“…Ohtsuki et al [18] reported that 15 (60%) of 25 acquired esotropia patients at mean age 12 years recovered stereopsis of more than 60 seconds and the duration of esotropia or age of onset did not significantly affect the recovery. In contrast, Kassem and Elhilali [19] reported that the possibility of binocular vision recovery was higher when the duration of esotropia was shorter and the age of surgery was younger in acquired esotropia cases of mean age 8.6 years. In particular, the duration of esotropia is the most influential factor on the stereopsis recovery in esotropia patients including accommodative esotropia [20].…”

Background: To analyze the surgical outcomes for adult patients diagnosed with acute acquired comitant esotropia (AACE). Methods:Medical records of 21 patients who had undergone surgery for AACE were retrospectively analyzed. The main outcome measures were the final motor and sensory success rate after surgery and factors affecting motor and sensory outcomes. Motor success was considered alignment within 8 prism diopter (PD) at both near and distance and sensory success was stereoacuity ≥60 sec/arc. Results:The preoperative mean esodeviation angles were 33.0 ± 11.6 PD at distance and 32.6 ± 10.8 PD at near. The mean period of postoperative follow up was 8.1 ± 4.5 months (range 3-8 months). The postoperative mean esodeviation angles at final follow-up time were 4.1 ± 5.7 PD at 2 distance and 3.9 ± 5.6 PD at near. The surgical motor success rate at final follow-up was 76.2% (16/21). The sensory success rate at final follow-up was 55.5% (11/21). The factor affecting the motor outcome was the type of surgery (p < 0.05). The factor affecting sensory outcome was postoperative follow-up time (p < 0.05). Conclusions: Surgery type appears to affect surgical motor outcomes in adults with AACE. Although the sensory outcome was favorable, it seems that regaining bifoveal fixation takes time.

“…[21–24] Previous studies of congenital or infantile esotropia have shown that it is possible to obtain sensory and motor fusion by surgical alignment and prism glasses,[20, 21] and other studies on esotropia of adults also showed improvement in binocular function when the motor alignment was adjusted through surgery.

PurposeIn partially accommodative esotropia (PAET), prism glasses can correct small angles of residual esotropia but the long-term effect of prismatic correction alone without surgery has not been reported. We aimed to investigate the long-term outcome of prism glasses after full hypermetropic correction for PAET.MethodsThis retrospective, case-control study was performed for children aged 10 years or younger with a residual esotropia of ≤ 20 prism diopters (PD) after full hypermetropic correction who were fitted with prism glasses and followed-up for 3 years or more. Clinical characteristics and the angle of esodeviation were obtained at each follow-up examination. Successful motor outcome after 3 years of prismatic correction was determined if the residual angle of esotropia after full hypermetropic correction was ≤ 10PD. Patients who eventually weaned off prism glasses were noted.ResultsAmong 124 patients, 30.6% achieved success and 7.3% weaned off prism glasses after 3 years of prism-wear. Smaller amount of latent esodeviation (P = 0.001) revealed by prism adaptation and good fusional response at near with the Worth 4-dot test were significant prognostic factors of success by multivariate analysis (P = 0.033). After 3 years of wearing prism glasses, the rate of improvement in stereoacuity was higher in the Success group (60.5% vs 27.9%) (P = 0.001), however, there was no significant difference between the prism-weaned group and prism-wearing group within the Success group (P>0.05).ConclusionPrism glasses for small angle PAET can be a treatment option in patients who have a small angle of latent esodeviation revealed by prism adaptation and good sensory fusion at near. Otherwise, early surgery may be advisable as the majority of patients showed suboptimal outcome even after long-term prism-wear.
