Abstract：
OBJECTIVE: The recent pandemic has identified the need for telemedicine assessment of ophthalmology patients. A vital component of such assessment is visual acuity (VA) measurement. The aim of this study was to determine the feasibility and reliability of computerised \'at home\' VA measurements using COMPlog software.
METHODS: A Bland Altman method comparison study of worse eye \'in clinic\' and \'at home\' orthoptist-supervised COMPlog computerised VA measurements. Subjects underwent gold standard semi-automated computerised test and retest logMAR VA measurements on their habitually corrected worse eye both \'in clinic\' and \'at home.\' The orthoptist ran the test from the eye clinic with the patient viewing a secondary PC monitor either in the same clinic room or at home. A screen sharing voice and video conferencing application and standard consumer IT hardware were employed to present the test optotypes in the patient\'s home.
RESULTS: 23 paediatric and 13 adult patients with a range of ocular diseases and worse eye visual acuities were included (range -0.14 to 1.06 logMAR). No significant bias was found between \'in clinic\' and \'at home\' measurements (mean -0.01 logMAR and 95% confidence interval -0.03, 0.00 logMAR). Test-retest variability of \'in clinic,\' \'at home\' and \'in clinic\' versus \'at home\' measurements were within normal reported ranges at 0.12 logMAR (6 ETDRS letters) or less.
CONCLUSIONS: Remote home VA testing performed by an eye care professional using a semi-automated VA measurement program and video conferencing application provided unbiased measurements with acceptable test-retest reliability. Home testing was both feasible and acceptably reliable in appropriately equipped patients.

摘要：
■最近的大流行已确定需要对眼科患者进行远程医疗评估。这种评估的重要组成部分是视敏度(VA)测量。这项研究的目的是确定使用COMPlog软件在家中进行计算机化的VA测量的可行性和可靠性。
■BlandAltman方法比较研究了“在诊所”和“在家中”由骨科医师监督的COMPlog计算机进行的VA测量。受试者在诊所和家中对习惯性矫正的不良眼睛进行了金标准半自动计算机测试和重新测试logMARVA测量。\'骨科医生从眼科诊所进行测试，患者在同一诊所或家中查看辅助PC监视器。使用屏幕共享语音和视频会议应用程序以及标准的消费者IT硬件在患者家中展示测试视标。
■包括23名儿科和13名患有一系列眼部疾病和视力较差的成年患者（范围为-0.14至1.06logMAR）。在诊所和家庭测量之间没有发现明显的偏差（平均-0.01logMAR和95％置信区间-0.03，0.00logMAR）。临床中的重测变异性，\'\'在家中\'和\'在诊所\'与\'在家中\'测量值在0.12logMAR(6个ETDRS字母)或更小的正常报告范围内。
■由眼睛护理专业人员使用半自动VA测量程序和视频会议应用程序进行的远程家庭VA测试提供了具有可接受的测试-重测可靠性的无偏测量。在配备适当的患者中，家庭测试既可行又可靠。
