Office Based Vergence and Accommodative Therapy and Intermittent Exotropia

Intermittent Exotropia Clinical Trial

Official title:
Pilot Study of Office Based Vergence and Accommodative Therapy as Treatment of Intermittent Exotropia

Clinical Trial Summary

This pilot study is designed specifically to determine the short-term effect of OBVAT on intermittent exotropia in terms of 4 key areas (Standardizing reported outcomes of surgery for intermittent exotropia): control score, alignment, near stereoacuity and quality of life score. Result of this pilot study will be used to determine whether a full-scale RCT should be conducted to evaluate the short and long term effectiveness of OBVAT.

Clinical Trial Description

All enrolled px received 16-20 sessions of OBVAT, 60 minutes per visit, one time per week; Home reinforcement, 15 minutes each time, five times per week.

1. Primary outcome measureļ¼š A. Change in the office based intermittent exotropia control score

2. Secondary outcome measures A. Change in Look And Cover, then Ten seconds of Observation Scale for Exotropia (LACTOSE) B. Change in Newcastle Control Score (NCS) C. Change in Chinese intermittent exotropia questionnaire (CIXTQ) D. Change in near stereopsis by Preschool randot near stereoacuity E. Change in size of distant deviation angle by prism alternating cover test F. Change in size of near deviation angle by prism alternating cover test ;
