Healthcare access is one of the determinants of visual impairment (VI), as a public health problem. The objective of this study was to estimate VI prevalence, related causes, and its correlation with access to physicians in Iran.
: This systematic review and meta-analysis include observational studies published in Iran. PubMed, Web of Science, Scopus, Google Scholar, and local databases were systematically searched by using the MeSH headings. Data on the provincial distribution of physicians, as an index of access to healthcare, was retrieved. A random-effect meta-analysis was performed to assess.
Eight articles were included. The pooled prevalence of blindness, low vision, and VI was 0.80% (95% CI: 0.61-0.99%), 2.92% (95% CI: 2.40-3.44%), and 5.57% (95% CI: 4.71-6.43%). Refractive errors were the most common causes of VI based on PVA with the pooled prevalence of 54.6% (95% CI: 43.4-65.8%). Based on BCVA, we found that the pooled prevalence of cataracts was 37.4% (95% CI: 29.5-45.3%) as the most common cause of VI. The results of metaregression showed that the greater number of general practitioners (GPs) ( value = 0.01) and pharmacists ( value = 0.024) per population were associated with a lower prevalence of blindness.
Some of the main causes of visual impairment in Iran are preventable. Access to healthcare services may lead to early diagnosis of preventable causes of VI. Further well-designed studies and national surveys should be conducted to provide accurate data from different regions of Iran.
作为一个公共卫生问题，医疗服务可及性是视力损害（VI）的决定因素之一。本研究的目的是估计伊朗的视力损害患病率、相关病因及其与医生可及性的相关性。
本系统评价和荟萃分析纳入了在伊朗发表的观察性研究。使用医学主题词对PubMed、科学网、Scopus、谷歌学术和本地数据库进行系统检索。检索了作为医疗服务可及性指标的各省医生分布数据。进行随机效应荟萃分析以进行评估。
纳入8篇文章。失明、视力低下和视力损害的合并患病率分别为0.80%（95%CI：0.61 - 0.99%）、2.92%（95%CI：2.40 - 3.44%）和5.57%（95%CI：4.71 - 6.43%）。基于最佳矫正视力（PVA），屈光不正为视力损害最常见病因，合并患病率为54.6%（95%CI：43.4 - 65.8%）。基于最佳矫正视力（BCVA），我们发现白内障的合并患病率为37.4%（95%CI：29.5 - 45.3%），是视力损害最常见病因。元回归结果显示，每人口中全科医生（GPs）数量越多（值 = 0.01）以及药剂师数量越多（值 = 0.0
