This study aims to quantify the diagnostic test-accuracy of three visual function self-monitoring tests for detection of active disease in patients with neovascular age-related macular degeneration (nAMD) when compared with usual care. An integrated qualitative study will investigate the acceptability of these home-based testing strategies.
All consenting participants are provided with an equipment pack containing an iPod touch with two vision test applications installed and a paper journal of reading tests. Participants self-monitor their vision at home each week with all three tests for 12-18 months. Usual care continues over this period. Key eligibility criteria are: age ≥50 years; at least one eye with AMD with ≥6-≤42 months since first AMD treatment; and vision not worse than Snellen 6/60, LogMAR 1.04 or 33 letters. The primary outcome, and reference standard, is diagnosis of active disease during usual care monitoring in the Hospital Eye Service. Secondary outcomes include duration of study participation, ability of participants to do the tests, adherence to weekly testing and acceptability of the tests to participants.
Recruitment is in progress at five NHS centres. Challenges in procuring equipment, setting up the devices and transporting devices containing lithium batteries to participating sites delayed the start of recruitment. The study will describe the performance of the tests self-administered at home in detecting active disease compared to usual care monitoring. It will also describe the feasibility of the NHS implementing patient-administered electronic tests or similar applications at home for monitoring health.
本研究旨在定量比较三种视觉功能自我监测测试在检测新生血管性年龄相关性黄斑变性(nAMD)患者活动性疾病方面的诊断测试准确性,与常规护理相比。一项综合定性研究将调查这些基于家庭的测试策略的可接受性。
所有同意的参与者都将获得一个设备包,其中包含一个安装了两个视觉测试应用程序的 iPod touch 和一本阅读测试的纸质日记。参与者在家中每周使用所有三种测试进行 12-18 个月的自我监测视力。在此期间继续进行常规护理。主要入选标准为:年龄≥50 岁;至少一只眼患有 AMD,且自首次 AMD 治疗以来≥6-≤42 个月;视力不低于 Snellen 6/60、LogMAR 1.04 或 33 个字母。主要结局和参考标准是在医院眼科服务的常规护理监测期间诊断为活动性疾病。次要结局包括研究参与时间、参与者进行测试的能力、每周测试的依从性以及参与者对测试的接受程度。
该研究正在五个 NHS 中心进行招募。在采购设备、设置设备以及向参与地点运输含有锂电池的设备方面存在挑战,这延迟了招募工作的开始。该研究将描述在家中自我管理测试在检测活动性疾病方面的表现,与常规护理监测相比。它还将描述 NHS 在家中实施患者管理的电子测试或类似应用程序来监测健康的可行性。
