DESCRIPTION (provided by applicant): Over the past 20 years, major progress has been made in our understanding of the epidemiology and consequences of ocular disorders among older adults. A number of population-based studies in a variety of major ethnic groups in the United States have provided critical information for etiological research and planning for delivery of eye care services to this high risk population. The situation among children is much different. While extensive data exist on the visual status of the school age population through legislatively mandated vision testing programs in elementary schools, few such data exist in the United States regarding the frequency and severity of ocular disorders among preschool age children. We propose to address this lack of information by conducing a population-based prevalence survey of ocular disorders among children 6 months through 5 years in the communities of Northeast and Southeast Baltimore. Over 39,000 households in 31 census tracts will be screened in order to identify approximately 6800 eligible children. Assuming an 80% response to the examination, this will yield over 5,000 subjects for study. All families who agree to participate will receive an enrollment interview conducted by telephone or at their home. Children will then be transported to an examination facility set-up in their local community where a detailed eye examination will be conducted. The examination will include measurement of visual acuity, refraction, ocular motility and alignment. Subjects in whom abnormalities are discovered will be referred to their preferred source of pediatric eye care for clinical management. A subset of children diagnosed with ocular disorders will receive a confirming examination by a pediatric ophthalmologist at the Wilmer Institute of Johns Hopkins School of Medicine. The analysis will focus on estimating the age and race-specific prevalence of ocular disorders in this group and on assessing the association of selected risk factors with the prevalence of these disorders.

描述（由申请人提供）：在过去的20年中，我们对老年人眼部疾病的流行病学和后果的理解取得了重大进展。在美国各种主要种族中进行的许多基于人群的研究为病因研究和计划提供了关键信息，以向这一高风险人群提供眼保健服务。儿童的情况大不相同。 尽管通过在小学的立法视觉测试计划中存在有关学龄面年龄人口的视觉状况的广泛数据，但在美国，几乎没有此类数据涉及学龄前儿童中眼部疾病的频率和严重性。我们建议通过在巴尔的摩东北部和东南部的6个月至5年的儿童中对基于人群的患病率进行基于人群的患病率调查来解决这种缺乏信息。将筛选31个人口普查区中的39,000多家家庭，以确定大约6800名合格的儿童。假设对考试有80％的反应，这将产生超过5,000多名研究受试者。所有同意参加的家庭都将接受电话或家里进行的招生面试。然后，儿童将被运送到其当地社区的考试设施，并进行详细的眼睛检查。检查将包括视力，折射，眼运动性和比对的测量。发现异常的受试者将转介其首选的儿科护理来源用于临床管理。约翰·霍普金斯医学院威尔默研究所的小儿眼科医生的一部分被诊断出患有眼部疾病的儿童将接受确认检查。该分析将着重于估计该组中眼疾病的年龄和种族特异性患病率，并评估所选危险因素与这些疾病患病率的关联。
