项目摘要
A pressing unmet need in the field of glaucoma diagnostics is to find methods for objective detection of
disease worsening or prediction of visual field (VF) progression in eyes with advanced disease. Eyes with
advanced glaucoma are at high risk of losing the remaining vision and blindness. Retinal nerve fiber layer
(RNFL) and optic nerve head measures reach their measurement floor as glaucoma progresses beyond the
early stages. Hence, functional assessment of the central VF is currently the main tool for monitoring advanced
glaucoma. Our central hypothesis is that assessment of the macular retinal ganglion cell (RGC)/axonal
complex can lead to improved detection or prediction of disease progression since the last RGCs to disappear
in glaucoma reside in the central retina (the macula). We will test this hypothesis in a cohort of glaucoma
subjects just reaching 5 years of follow-up and validate our methods in separate cohorts of glaucoma and
normal subjects. Aim 1. Are macular thickness measures able to detect change earlier and with a stronger
signal compared to RNFL measures in advanced glaucoma? We will measure progression rates for global and
local macular and RNFL measures within a Bayesian hierarchical framework. We will compare progression
rates and the proportion of progressing eyes/regions/sectors for macular and RNFL measures to normal eyes
and account for differing scales, age-related decay, and treatment. Aim 2A. Can macular OCT thickness
changes confirm and predict changes in central VFs for advanced glaucoma? We will estimate
longitudinal/temporal structure-function relationships with Bayesian joint hierarchical longitudinal modeling of
macular OCT and central 10° VF measures. These models will determine whether there is a contemporaneous
or lagged deterioration of OCT and VF. We will assess the influence of baseline disease severity, treatment
and other covariates on these joint longitudinal models. We will also compare the joint macular/central VF
models to joint models of RNFL and 24° VFs and develop functional prediction models from 1 to 4 years
ahead. Aim 2B. To validate the performance of prediction models, we will initiate a second prospectively
enrolled cohort of patients meeting similar inclusion criteria and matched to the original cohort by age, gender,
ethnicity and baseline glaucoma severity. We will compare VF point predictions (e.g., one- or two-visit step
ahead) to the observed VF data. Aim 3. Develop software for combining macular structural and functional data
in real time as a clinical tool for detection or prediction of progression. It will provide clinicians with
structural/functional rates of change and structural ‘step’ changes from baseline, and the probability and
distribution of predicted functional changes The information provided by the application can be used during a
clinical encounter to make decisions regarding ongoing management of glaucoma. Widespread real-time use
of our software will result in significant improvements in disease monitoring and timely treatment of progressive
glaucoma through advanced stages and will help reduce visual disability from glaucoma.
青光眼诊断领域的压迫未满足的需求是找到客观检测的方法
疾病令人担忧或预测患有晚期疾病的眼睛的视野(VF)进展。眼睛
晚期青光眼有失去剩余视力和失明的高风险。视网膜纤维层
随着青光眼的发展,(RNFL)和视神经头测量达到了测量地板
早期阶段。因此,中央VF的功能评估目前是监视高级的主要工具
青光眼。我们的中心假设是评估黄斑视网膜神经节细胞(RGC)/轴突
复合物可以改善疾病进展的检测或预测,因为最后一次RGC消失了
在青光眼中居住在中央视网膜(黄斑)中。我们将在青光眼组中检验该假设
受试者仅达到5年的随访,并在单独的青光眼群体中验证我们的方法
正常受试者。 AIM 1。是黄斑厚度测量值,可以更早检测变化,并且更强
与晚期青光眼中的RNFL度量相比,信号?我们将衡量全球和
贝叶斯分层框架内的本地黄斑和RNFL测量。我们将比较进步
速率和进步的眼睛/区域/部门的黄斑和RNFL措施的比率和正常眼睛
并说明量表,与年龄有关的衰减和治疗。目标2a。黄斑oct厚度可以吗
变化确认并预测晚期青光眼中央VF的变化?我们将估计
纵向/时间结构 - 功能与贝叶斯关节分层纵向建模的关系
黄斑OCT和中心10°VF测量。这些模型将决定是否有同时代
或OCT和VF的滞后恶化。我们将评估基线疾病严重程度,治疗的影响
以及这些关节纵向模型的其他协变量。我们还将比较关节黄斑/中央VF
RNFL和24°VF的联合模型的模型,并将功能预测模型从1年到4年开发
目标2B。为了验证预测模型的性能,我们将启动第二次可能
符合类似纳入标准的患者队列的招募队列,并按年龄,性别,与原始队列相匹配
种族和基线青光眼严重程度。我们将比较VF点的预测(例如,一个或两次访问的步骤
提前)到观察到的VF数据。目标3。开发用于结合黄斑结构和功能数据的软件
实时作为检测或预测进展的临床工具。它将为临床医生提供
变化的结构/功能速率和结构“步骤”的变化与基线以及概率和
预测功能更改的分布应用程序提供的信息可以在
临床遭遇以做出有关青光眼治疗的决定。广泛的实时使用
我们的软件将导致疾病监测仪的重大改善和及时治疗进行性治疗
青光眼通过晚期阶段,将有助于减少青光眼的视觉障碍。
