DESCRIPTION (provided by applicant): This proposal is for the University of Alabama at Birmingham Clinical Center to continue to annually examine the 127 currently enrolled COSMICC participants (only 5 subjects are lost to follow-up since enrollment in 1997-98) for an additional 5 yrs (total follow-up, 14 yrs) following the COSMICC2 protocol. The data collected from this center will be used to address the specific aims described in more detail in the Chair application and summarized briefly here: 1) to use mathematical functions (the Gompertz function and others) to model myopia progression in the 58% of COSMICC subjects with progressing myopia and to develop predictive models and test hypotheses based on previously identified risk factors (age, ethnicity, parental myopia); 2) to test 4 hypotheses related to environmental risk factors for myopia progression and stabilization and axial elongation in this well-characterized cohort of myopes; and 3) to test three hypotheses related to risk factors for the development of myopia-related changes in IOP, CCT and macular thickness in COSMICC subjects. The high prevalence of myopia (25% of the US adult population) and its prominence as a public health problem (risk factor for conditions that can cause vision loss and blindness) emphasize the importance of gaining increased understanding of mechanisms underlying progression and eventual stabilization, so that in the future myopia might be limited to low levels. Better understanding of the factors predictive of myopia progression and stabilization also will help guide selection and timing of interventions as well as target those groups that may benefit the most from treatment.

描述（由申请人提供）：该提案是针对伯明翰临床中心的阿拉巴马大学继续检查目前注册的COSMICC参与者的127名（自1997 - 98年入学以来，只有5名受试者丢失了5名受试者）遵循COSMICC2协议的5年（总随访，14年）。从该中心收集的数据将用于解决椅子应用程序中更详细描述的具体目的，并在此处简要概述：1）使用数学功能（Gompertz功能和其他功能）来建模Cosmicc 58％的近视进展。基于先前确定的风险因素（年龄，种族，父母近视）的受试者，并开发了预测模型和检验假设； 2）测试4个与环境风险因素有关的假设，用于近视的进展，稳定和轴向伸长率，在这种良好的近视群体中； 3）测试与COSMICC受试者IOP，CCT和黄斑厚度与近视相关的变化发展的三个假设。近视的高患病率（占美国成年人口的25％）及其作为公共卫生问题（可能导致视力丧失和失明的危险因素）的突出率强调了对基本进展和最终稳定机制的理解的重要性，因此，将来近视可能仅限于低水平。更好地了解近视进展和稳定的因素也将有助于指导干预措施的选择和时机，并针对那些可能受益于治疗最大的群体。
