To determine agreement between diurnal variation testing (DVT) of intraocular pressure (IOP) with Goldmann applanation tonometer (GAT) and iCare HOME (IH) by an optometrist (OP) and home monitoring by participants (PT).
Patients (18-80 years) with glaucoma and suspects were enrolled. IH IOP and GAT were taken by an OP at 2 h intervals from 8 AM to 4 PM on Day 1 and PT between 6 AM and 9 PM, for the next 2 days. IOP, date, and time were viewed via iCare LINK software.
IN TOTAL,: 72.9.
(: 51/70) PT trained were able to take reliable readings. One hundred two eyes (51 patients, age 53 ± 16 yrs) were analyzed. Correlation between optometrist (OP) and participants (PT) was strong and positive {IH OP-IH PT- r = 0.90, p-0.0001;IH PT-GAT- r = 0.79, p-0.0001}. Agreement by Bland Altman plots was limited {IH OP-IH PT mean 0.1 mmHg (95% LOA -5.3 to 5.5), IH PT-GAT 2.2 mmHg (-5.7 to 10.1)}. Intraclass correlation coefficient for IH OP-IH PT was 1.18 (95% CI 1.37-1.09). Intradevice {0.95 (95% CI 0.94-0.97)} and interrater repeatability {0.91 (0.79-0.96)} were good. 37% of eyes had a synchronous peak on GAT and IH during the day DVT.
Home tonometry by iCare HOME is easy, feasible, but due to limited agreement cannot substitute GAT DVT.
通过验光师（OP）进行的眼压（IOP）昼夜变化测试（DVT）和参与者的家庭监测，来确定 Goldmann 压平眼压计（GAT）和 iCare HOME（IH）之间的一致性。
纳入青光眼和疑似患者。在第 1 天，OP 在上午 8 点至下午 4 点每隔 2 小时使用 IH 和 GAT 进行测量，在接下来的 2 天，参与者（PT）在上午 6 点至晚上 9 点之间进行测量。IOP、日期和时间通过 iCare LINK 软件查看。
总共：72.9。（70 例中有 51 例，年龄 53±16 岁）。102 只眼（51 例患者）进行了分析。OP 和 PT 之间的相关性较强且为正相关（IH OP-IH PT-r=0.90，p<0.0001；IH PT-GAT-r=0.79，p<0.0001）。Bland-Altman 图的一致性有限（IH OP-IH PT 平均 0.1mmHg（95% LOA-5.3 至 5.5），IH PT-GAT 2.2mmHg（-5.7 至 10.1））。IH OP-IH PT 的组内相关系数为 1.18（95%CI 1.37-1.09）。设备内（0.95（95%CI 0.94-0.97））和观察者间重复性（0.91（0.79-0.96））均良好。37%的眼在白天 DVT 期间，GAT 和 IH 有同步高峰。
iCare HOME 的家庭眼压测量简单可行，但由于一致性有限，不能替代 GAT DVT。
