我從下面(https://www.icaretonometer.com/wpcf-publications/accuracy-of-measurements-of-the-icare-home-rebound-tonometer/)
找到部分答案了 , 注意結論那一段 ,我眼壓偏低,每次使用ICARE HOME 與醫院噴氣設備對比都會差3~4 mmHG ,
文章提到這款ICARE HOME 對於眼壓太低,會低估 ,對於眼壓太高,會高估,以我本身左眼經過小樑手術 4個多月期間,使用 ICARE HOME
24HR 測落在2~7之間(半夜到7 ,僅有少數1~2次會到8) ,白天對比醫院測的值,都要再加3~4才會等於噴氣,但文章中並沒有說眼壓低到
多少會低估,高到多少會高估,不知有沒有青友有這方面的答案或相關的資料
Accuracy of measurements of the iCare HOME rebound tonometer Purpose: To evaluate the accuracy of intraocular pressure (IOP)
measurements of the newly available iCare HOME (RT-HOME)
rebound tonometer compared to the iCare ONE (RT-ONE) rebound
tonometer and Goldmann applanation tonometry (GAT). Methods: In case of sixty-four patients (mean age 57.66 ± 19.48
years) IOP measurements were obtained with each of the abovementioned
tonometers by an ophthalmologist (o). In addition, patients
(p) measured their own IOP with the RT-HOME and the RT-ONE.
The means and standard deviation for all tonometers were compared.
Agreement between the tonometers was calculated using Bland-
Altman plots. Results: Mean IOP’s obtained were 15.23 ± 6.42 mmHg (RTONE(
o)), 15.07 ± 6.68 mmHg (RT-ONE(p)), 14.36 ± 6.24 mmHg
(RT-HOME(o)), 14.48 ± 6.08 mmHg (RT-HOME(p)) and 15.31
± 4.40 mmHg (GAT). Bland-Altman analysis revealed a mean
difference (bias) between RT-HOME(o) and RT-ONE(o), between
RT-HOME(o) and RT-HOME(p), and between RT-HOME(o) and
GAT of -0.87, -0.21, and -0.95 mmHg, respectively, with 95%-limits
of agreement of -5.01 to 3.26, -5.39 to 4.97, and -7.58 to 5.68 mmHg,
respectively. Linear regression of the Bland Altmann Analysis at
RT-HOME(o) vs. GAT revealed a proportional error over the range of
pressures: slope = 0.37, p < 0.001. Conclusions: The measurement of both RT-HOME and RT-ONE
revealed in general a high congruency with the GAT. The highest
consistency of IOP measurements between (o) and (p) refers to
RT-HOME. Both rebound tomometers, in particular the RT-HOME,
indicated in average lower IOP values than those taken with the
applanation tonometry. RT-HOME seems to overestimate IOP in
higher IOP values and underestimate IOP in lower IOP range.作者: glaucoma2014 時間: 2020-6-16 17:13
