Background. We aimed to evaluate the association between maternal smoking and the occurrence of childhood refractive error and amblyopia. Methods. Relevant articles were identified from PubMed and EMBASE up to May 2015. Combined odds ratio (OR) corresponding with its 95% confidence interval (CI) was calculated to evaluate the influence of maternal smoking on childhood refractive error and amblyopia. The heterogeneity was evaluated with the Chi-square-based Q statistic and the I (2) test. Potential publication bias was finally examined by Egger's test. Results. A total of 9 articles were included in this meta-analysis. The pooled OR showed that there was no significant association between maternal smoking and childhood refractive error. However, children whose mother smoked during pregnancy were 1.47 (95% CI: 1.12-1.93) times and 1.43 (95% CI: 1.23-1.66) times more likely to suffer from amblyopia and hyperopia, respectively, compared with children whose mother did not smoke, and the difference was significant. Significant heterogeneity was only found among studies involving the influence of maternal smoking on children's refractive error (P < 0.05; I (2) = 69.9%). No potential publication bias was detected by Egger's test. Conclusion. The meta-analysis suggests that maternal smoking is a risk factor for childhood hyperopia and amblyopia.

Search Forms Search is at the core of Embase and all search forms are designed to allow you to look for biomedical and pharmaceutical clinical and research information easily and quickly, whether you are a new or experienced searcher. The Embase search engine allows Boolean searching with wildcard and truncation features, as well as many predefined search limits. Search is divided into five options: Quick, Advanced, Drug, Disease and Article. Quick lets you perform easy yet powerful searches without having to learn a complex search language. It is perfect if you are starting your research and looking for an overview of the literature or good terms to include in your search strategy. Autocomplete will help you to search using the bext terminology. Advanced incorporates options from Emtree term mapping including explosion searching for maximum precision in subject searching (see Emtree) and Drug and Disease provide access to specialized features useful to search these topics, such as ''Adverse Drug Reaction''''Drug Combination''. Generally speaking, drug searches are best carried out in the Drug form, diseases in the Disease form and non-drug and disease searches in the Advanced form. Article allows you to pinpoint individual articles. Embase is owned and operated by Elsevier B.V., Radarweg 29, 1043 NX Amsterdam, The Netherlands, Reg. No. 33156677, BTW No. 002967455B65 (Elsevier).
