With the release of the new HOME2 tonometer, we are providing a deep discount on these pre-owned devices for patients that would like to own an original iCareHOME tonometer. Patients trained to use the iCare HOME device can do so with fair accuracy compared with trainers with accuracy improving within 1 week of usage. All of the MyEyes pre-owned iCare HOME tonometers are gently used by patients in our rental program. 65% of patients agreed the device was easy to use and 89% would recommend the device to other glaucoma patients. No distinct trend in test-retest variability was identified over the 7-day period. At the postloan visit, inter-rater reliability was good for right eye readings and excellent for left eye readings. Good inter-rater reliability was observed between iCare HOME measurements by the glaucoma nurse clinician and patients. Up to 32 patients (80%) were able to obtain IOP readings within 3 mm Hg of the glaucoma nurse clinician’s readings at the preloan visit, and up to 36 patients (90%) at the postloan visit. A 5-point Likert scale questionnaire was used to assess the patient’s experience with the device. Intraclass correlation coefficient compared inter-rater reliability of iCare HOME measurements, and test-retest variability for the patient’s readings over the 7-day period were analyzed. Bland-Altman analysis was used to assess agreement between Goldmann applanation tonometer and iCare HOME readings. Patients were trained to use the iCare HOME and measured their IOP twice daily over a loan period of 7 days. Materials and Methods:Ī total of 40 glaucoma patients had IOPs measured using the Goldmann applanation tonometer and the iCare HOME. The aim was to compare the accuracy of IOP measurements of trained glaucoma patients using the iCare HOME tonometer before and after a week of self-monitoring at home and study the repeatability of patient measurements done at home. This is an abstract that was submitted for the 2018 ARVO Annual Meeting, held in Honolulu, Hawaii, April 29 - May 3, 2018.The iCare HOME tonometer is a useful tool which can be used by patients for fairly accurate and reliable self-measurement of intraocular pressure (IOP). It also provides early evidence of the importance of monitoring diurnal IOP in tailoring management to the individual. These results showed a possible link between elevated IOP outside office hours and rapid RNFL progression. The unit documented higher IOP spikes in certain patients than those recorded within office hours. Icare® HOME tonometry was feasible for most of our participants with suitable single session training (average 15 to 20 min). iCare HOME2 Self-Tonometer Intraocular pressure measurement taken by this device at home is not a substitute for measurements obtained within an eye care. Examples of these patients will be presented to elucidate the role of Icare HOME tonometry in modifying their treatment plan. The mean RNFL GPA of patients with no recorded elevated IOP was significantly lower -1.5 ± 1.8 µm/year (p-value of 0.0001). These twelve participants showed significant progression on retinal nerve fibre layer (mean RNFL GPA -3.9 ± 2.9 µm/year). 12 (7.8%) out of 153 patients had elevated IOP outside office hours not previously recorded before in the clinical setting (mean spike IOP of 35.6 ± 8.2 mmHg), which is higher than the mean IOP for these patients recorded in the clinic (21.4 ± 5.0 mmHg, p-value 0.0001). 153 (84.1%) patients successfully completed the required measurements. 182 (90.1%) were recruited and provided with education in the use of the Icare tonometer, of which 29 (15.9%) did not complete the measurements. 20 patients declined to participate for logistic reasons. Patients were asked to measure their eye pressure four times per day for 2 to 4 consecutive days including early morning and late evening timepoints.Ģ02 patients were invited to the study. Patients were selected for IOP self-measurement, and were instructed on the use of the Icare HOME tonometer. Glaucoma progression was detected using optical coherence tomography of the retinal nerve fibre layer (RNFL). Glaucoma participants were invited to perform home tonometry from a prospective study of glaucoma progression (PROGRESSA). To investigate the value of the clinical results of Icare HOME tonometry, and to elucidate possible roles in modifying glaucoma management plans.
