目的：研究导致澳大利亚成年人双眼视力障碍的眼部疾病的特定病因患病率。两个地点，以人群为基础的横断面研究。参与者：参与者在招募研究时年龄在40岁及以上，住在自己的家里。这项研究是在1992-1996年间进行的。方法：本研究采用整群分层随机抽样方法，从维多利亚州的城市和农村两个队列中抽取4744名参与者。参与者完成了标准化的访谈和眼部检查，包括呈现和最佳矫正视力、视野和扩大的眼部检查。所有被发现视力受损的参与者都被确定了导致视力丧失的主要原因。基于人群的患病率估计是加权的，以反映维多利亚州两个队列的年龄和性别分布。主要结果衡量标准：视力损害的定义是基于最佳矫正视力或视野的四个严重程度：
Purpose: To study the cause-specific prevalence of eye diseases causing bilateral visual impairment in Australian adults.Design. Two-site, population-based cross-sectional study.Participants: Participants were aged 40 years and older and resident in their homes at the time of recruitment for the study. The study was conducted during 1992 through 1996.Methods: The study uses a cluster stratified random sample of 4744 participants from two cohorts, urban, and rural Victoria. Participants completed a standardized interview and eye examination, including presenting and best-corrected visual acuity, visual fields, and dilated ocular examination. The major cause of vision loss was identified for all participants found to be visually impaired. Population-based prevalence estimates are weighted to reflect the age and gender distribution of the two cohorts in Victoria.Main Outcome Measures: Visual impairment was defined by four levels of severity on the basis of best-corrected visual acuity or visual field:
