PURPOSE：描述视力受损的老年人的特征的时间变化，他们的眼睛可以通过屈光矫正。设计：对一个社区相隔6年的两个横断面进行研究。方法：对1992~1994年(横断面1)的3654名49~97岁人群和1997~2000年(横断面2)的3509人(2335名幸存者加上1174名迁入该地区和年龄组的人)进行了蓝山眼科研究。分别于屈光前后测量最小分辨角视敏度的对数。可矫正的视力损害定义为屈光前较好的眼，屈光后改善至无损害(大于或等于20/40)的视力损害。结果：横断面1和横断面2具有相似的年龄性别分布。在横断面1中，7.5%的受试者有可矫正的视力损害，3.6%的受试者有不可矫正的视力损害，88.9%的受试者没有损害。2号交叉的符合率分别为5.6%、2.7%和91.7%。在这两个横断面中，相似比例(约68%)的视障患者有可矫正的视力损害，而相似的社会人口统计学指标预测了可矫正的视力损害。在控制了年龄和性别后，已婚、拥有自己的房子、有很高的工作声望、高中毕业后获得资格证书或目前是司机的参与者患上可纠正的视力障碍的可能性较小。在独居、使用社区支持服务、依赖他人、近视、戴远距离眼镜或自认为健康和心脏病较低的人中，正确、有能力的视力损害的调整后的几率增加。中风、癌症和糖尿病的病史在可矫正视力损害组和无视力损害组之间相似。结论：在老年人群中，社会经济参数、近视、戴远距眼镜、报告的健康问题和不良的自感健康与可矫正的视力损害相关。(C)2002年，爱思唯尔科学公司。保留所有权利。
.PURPOSE: To describe temporal changes in the characteristics of older persons with visual impairment in their better eye correctable by refraction.. DESIGN: Study of two cross sections of a community 6 years apart.. METHODS: The Blue Mountains Eye Study examined 3654 persons aged 49 to 97 during 1992 to 1994 (cross-section 1) and 3509 persons (2335 cohort survivors plus 1174 persons who moved to the area and age group) during 1997 to 2000 (cross-section 2). Logarithm of minimal angle of resolution visual acuity was measured before and after refraction. Correctable visual impairment was defined as visual impairment < 20/40 in the better eye before refraction that improved after refraction to no impairment (greater than or equal to 20/40). Factors associated with correctable visual impairment and persistent correctable impairment were determined..RESULTS: Cross-sections 1 and 2 had similar aged gender distributions. In cross-section 1, 7.5% of participants had correctable visual impairment, 3.6% had noncorrectable visual impairment, and 88.9% had no impairment. Corresponding rates in cross,section 2 were 5.6%, 2.7%, and 91.7%. In both cross sections, similar proportions (around 68%) of those visually impaired had correctable visual impairment and similar sociodemographic measures predicted correctable visual impairment. Cross-section 1 participants who were married, owned their home, had high job prestige, gained qualifications after high school, or were current drivers were less likely to have correctable visual impairment after controlling for age and gender. Adjusted odds for correct, able visual impairment increased in those living alone, using community support services, dependent on others, with myopia, wearing distance glasses, or with low perceived health and heart disease. Histories of stroke, cancer, and diabetes were similar between groups with correctable and no visual impairment.. CONCLUSION: Socioeconomic parameters, myopia, wearing distance glasses, reported health problems, and poor perceived health were associated with correctable visual impairment in this older population.
