A recent prospective multicenter data collection study has provided additional guidance on management.

It was concluded that either prism or surgery were reasonable initial treatment strategies. Although allocation bias precluded formal comparison of prism versus surgery (evident in baseline differences between groups), there were hints that surgery may yield superior outcomes. For surgery, the most common approach was bilateral medial rectus recession, which was highly successful when assessed 10 weeks and 12 months postoperatively. It was unclear whether adjustable sutures were helpful, but in the vast majority of adjustable cases, additional recession at the time of adjustment was performed, suggesting that larger than standard surgical doses are needed.</p>","PeriodicalId":37288,"journal":{"name":"Journal of Binocular Vision and Ocular Motility","volume":"72 4","pages":"230-233"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9608332/pdf/nihms-1821197.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41152337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
