PurposeTo study the longitudinal rehabilitation of binocular visual function in adolescent intermittent exotropia (IXT) after successful surgery and compare the results with those of a normal population. The role of binocular function in ocular alignment stability was also evaluated postoperatively.MethodsIn this prospective study, 30 adolescents with IXT successfully corrected after 1 month were followed for 12 months, and 30 children with normal vision were enrolled as controls. Stereopsis, the fusional vergence amplitude, sensory fusion, and accommodative flexibility were measured to assess binocular function at baseline and 6 and 12 months postoperatively. The controls were tested once when they were enrolled in the study.ResultsThe deviation was −32.00 ± 8.60 prism diopters (PD) at distance fixation and −36.0 ± 9.10 PD at near fixation preoperatively with an average correction of 28.53 ± 3.79 PD and 30.67 ± 1.34 PD at 1 month postoperatively. Distance stereoacuity and near stereoacuity improved from 1 to 12 months postoperatively (p = 0.025 and p = 0.041, respectively). Compared with the controls, the fusional convergence reserve at distance (p = 0.025) and near (p = 0.033) fixations and fusion reserve ratio at distance (p = 0.000) and near (p = 0.000) fixations remained subnormal, whereas sensory fusion (p = 0.237), distance stereopsis (p = 0.120), and the fusional divergence amplitude at a distance (p = 0.168) were normal. However, no significant correlations were found between binocular functions at 1 month postoperatively and the postoperative drift.ConclusionBinocular function significantly improved from before to after successful corrective surgery and continued to improve from 1 to 12 months postoperatively in adolescents with IXT. No significant correlations were found between binocular functions at 1 month postoperatively and ocular alignment stability.

Purpose. To evaluate whether clinical measures of postoperative binocular functions could predict the long-term stability of postoperative ocular alignment in children with intermittent exotropia. Methods. A retrospective study was performed in thirty-nine children (median: 7 years) who have been surgically treated from intermittent exotropia without overcorrection (less than 10 prism diopters [pd] of exodeviation at 1 month postoperatively). Angles of deviation and binocular functions were measured preoperatively and at 1 month, 6 months, and the final follow-up visit (≥24 months) postoperatively. We examined the relationships between postoperative drift (change of ocular alignment) and binocular functions (sensory fusion, fusional convergence amplitude, and stereoacuity). Results. The surgical success rate (esophoria/tropia ≤5 pd to exophoria/tropia ≤10 pd) dropped to 76.9% at 6 months after surgery and to 53.8% at individuals’ last visit (mean: 37 months). The mean exodrift was 7.7 ± 9.2 pd from the postoperative month 1 to the final visit (p<0.001) on distance fixation. Distance stereoacuity, central fusion, and fusional convergence amplitude significantly improved following surgery (p<0.05). However, no significant correlation was found between their binocular functions measured at the beginning of each follow-up period and the postoperative drift (all p>0.13). Conclusion. Our findings suggest that the clinical measures of sensory fusion, fusional convergence amplitude, and stereoacuity cannot serve as a robust predictor for the long-term stability of postoperative ocular alignment in patients who underwent successful surgery without overcorrection at 1 month postoperatively.

Posterior Ankle Impingement

Background: Posterior ankle impingement (PAI) is a known cause of posterior ankle pain in athletes performing repetitive plantarflexion motion. Even though empirically recommended in adult PAI, there is minimal literature related to the role of conservative physical therapy (PT) in pediatric patients. Purpose: To identify patient characteristics and determine if there is a difference in pediatric patients with PAI who were successful with conservative PT and those who were unsuccessful, requiring surgical intervention. Methods: Prospective study at a tertiary children’s hospital included patients <18 years diagnosed with PAI and underwent PT. Patients who received PT at an external facility were excluded. Collected data included demographics, initial presentation at PT evaluation, treatment throughout PT, patient presentation at PT discharge, time to return to sport (RTS) from initial PT evaluation (if successful), time to surgery from initial PT evaluation (if unsuccessful). Visual Analogue Scale (VAS) and American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores were collected. Group comparisons were conducted using independent t-tests or chi-square analyses (alpha level set at .05). Results: 31 (12 males, 19 females) patients diagnosed with PAI were enrolled with a mean age 12.61 years (range: 8-17). Gymnastics, football, and basketball were the most commonly implicated sports (42% patients). All patients underwent initial conservative PT for an average of 16.24 weeks (9.23 visits ±7.73). 20/31(64.5%) patients failed conservative management and underwent arthroscopic debridement. PAI pathology was predominantly bony in 61.3% and soft tissue 38.7%. Between the successful PT group and unsuccessful PT group, there was no difference in the proportion of athletes/non-athletes (p=.643). Average RTS time for successful group was 11.47 weeks and average time to surgery for unsuccessful group was 17.82 weeks. There were no significant differences in sex (p=.332), age (p=.674), number of PT visits (p=.945), initial weight-bearing status (p=.367), use of manual therapy (p=.074) including manipulation (p=.172) and mobilization (p=.507), sport (p=.272), initial evaluation ankle ROM (p>.05). Initial AOFAS scores for pain, function, alignment, or total were not significantly different (p=.551, .998, .555, .964 respectively). Conclusion: The first prospective study in pediatric patients with PAI demonstrates that even though success of PT is not dependent on age, sex, sport or PAI pathology, a notable proportion of patients who undergo PT do not need surgery. Conservative management including PT should be the initial line of management for PAI. PT treatment and surgery (if unsuccessful with PT) allowed patients to return to prior level of activity/sports.
