ABSTRACT

Purpose

To determine the prevalence of cataract and its relationship with some determinants in individuals above 60 years.

Methods

Of 3792 subjects that were invited, 3310 participated in the study (response rate = 87.31%). All subjects underwent full optometric, slit lamp, and fundoscopic examinations. Then, their lenses were evaluated according to the World Health Organization cataract grading system after pupil dilation.

Results

Age- and sex-standardized prevalence with 95% confidence interval (CI) of nuclear, cortical, posterior subcapsular cataracts (PSC), any type cataract, and all lens change was 53.09% (49.80 to 56.35), 23.02% (20.87 to 25.32), 5.57% (4.62 to 6.70), 58.78% (55.65 to 61.83), and 72.49% (70.14 to 74.71), respectively. Any type, nuclear, cortical, and PSC cataracts, had a positive association with age and an inverse association with education. Moreover, the prevalence of cortical and PSC cataract had an inverse association with economic status. Among all variables, age was the strongest determinant for cataract and its subtype.

Conclusion

This study found a higher prevalence of cataract compared to some previous studies such that about two-thirds of the geriatric population had cataract in the past or at the time of the study. Considering the association of cataract with variables such as economic status and education level, it seems that training and increased awareness and knowledge of the elderly population regarding the importance of eye care by physicians plays an important role in reducing the burden of cataract.

年龄相关性白内障的年龄和性别标准化患病率及其决定因素;德黑兰老年眼科研究 (TGES)

摘要

目的

确定 60 岁以上个体的白内障患病率及其与某些决定因素的关系。

方法

在受邀的 3792 名受试者中,有 3310 名受试者参与了研究(回复率 = 87.31%)。所有受试者均接受了全面验光、裂隙灯和眼底镜检查。然后,他们的镜片在瞳孔扩张后根据世界卫生组织白内障分级系统进行评估。

结果

核性、皮质性、后囊下白内障 (PSC)、任何类型白内障和所有晶状体变化的年龄和性别标准化患病率为 53.09% (49.80 至 56.35)、23.02% (20.87 至 25.32) 的 95% 置信区间 (CI) )、5.57%(4.62 至 6.70)、58.78%(55.65 至 61.83)和 72.49%(70.14 至 74.71)。任何类型的,核白内障、皮质白内障和 PSC 白内障,都与年龄呈正相关,与教育呈负相关。此外,皮质和 PSC 白内障的患病率与经济状况呈负相关。在所有变量中,年龄是白内障及其亚型的最强决定因素。

结论

这项研究发现,与之前的一些研究相比,白内障的患病率更高,大约三分之二的老年人在过去或研究期间患有白内障。考虑到白内障与经济状况和教育水平等变量的关联,似乎对老年人口进行培训并提高他们对医生眼保健重要性的认识和知识在减轻白内障负担方面起着重要作用。
