Efficacy of horizontal muscle augmentation combined inferior oblique muscle shortening for pediatric strabismus: Study Protocol

BACKGROUND: This study will explore the efficacy and safety of horizontal muscle augmentation (HMA) combined inferior oblique muscle shortening (IOMS) for the treatment of pediatric strabismus (PS). METHODS: Literature search for studies will be carried out in the following databases: Cochrane Library, MEDILINE, EMBASE, CINAHL, Web of Science, PsycINFO, CBM, and CNKI. We will search all these databases without language and publication status restrictions. Two independent authors will perform selection of studies, data collection and management, risk of bias evaluation. A third author will be consulted with the help of discrepancies. RESULTS: This study will provide a synthesis of existed evidence for HMA combined IOMS for the treatment of PS. CONCLUSION: The results of this study will provide evidence to evaluate the efficacy and safety of HMA combined IOMS for the treatment of PS, which can help to guide clinical decision-making.
