Intraocular pressure fluctuation before and after strabismus surgery: a systematic review

Abstract

<strong>Introduction:</strong> Intraocular pressure (IOP) can be influenced by several factors including corneal thickness, gender, refractive error, and the presence of diabetes mellitus. In the present study, we systematically reviewed published literature to find association between variations of IOP due to strabismus surgery.<br/><strong>Method:</strong> PubMed and Scopus were systematically searched with the following search terms: (intraocular pressure OR IOP) AND (strabismus) for the articles in which the fluctuation of IOP before and after strabismus surgery had been evaluated. All types of articles including case series, cross-sectional, clinical trials, and cohort studies with no time limitation were included in this study. Systematically searches, selection of articles, and the extraction of data were performed by two reviewers independently.<br/><strong>Result:</strong> 1617 out of 1674 articles were excluded due to duplication or irrelevancy. After step by step process of article selection, 57 relevant articles were included for further evaluation. However, only 8 articles met the inclusion criteria.<br/><strong>Conclusions:</strong> The results of this report showed that IOP may vary due to strabismus surgery, and it decreases after the surgery.
