Conclusion: Our study found that tonometry with iCare® Home has similar or less inter-user variation compared with GAT. The inter-user agreement was excellent for iCare® Home users (95% CI 0.93, ranging from 0.880 to 0.959) and moderate for GAT users (95% CI 0.741, ranging from 0.558 to 0.849). The correlation between different users with GAT was lower (0.769). The strongest correlation was between iCare® Home participants’ and trainers’ measurements (0.934). There was a statistically significant difference between the trainers’ measurements made with iCare® Home and those made with GAT ( p < 0.001), as well as between the GAT measurements made by trainers and those made by extra personnel ( p = 0.017). Results: Seventy-two per cent of iCare® measurements were within 3 mmHg of the GAT measurements. For each participant, intraocular pressure (IOP) was measured on the same occasion by two different healthcare staff using GAT as well as by a healthcare staff and the participant using the iCare® Home tonometer. Methods: Sixty-one participants were recruited to the study, including 24 glaucoma patients. Purpose: To investigate whether the inter-observer variation is similar between the Goldmann applanation tonometer used by healthcare staff and the iCare® Home tonometer used by glaucoma patients, volunteers and healthcare staff. VF should be further evaluated to ensure validity. Home monitoring may also improve upon glaucoma care by enhancing patient empowerment and fostering community bonds. ![]() Patients were able to perform these tests proficiently at home, and they were generally enthused to obtain more data about their intraocular health, as it allowed them a heightened sense of security and insight about their chronic disease, as well as a reduction in foreseeable barriers to care. HT and VF were acceptable and feasible in a small cohort of motivated subjects. Key themes include 1) Advantages of home monitoring 2) Difficulties with home monitoring 3) Future considerations in home monitoring and 4) The glaucoma patient experience. We identified 4 key themes with 33 subthemes. 100% of patients obtained an acceptable IOP and completed a VF test at home. 100% felt that VF was easy to use, and 94.4% found the VF useful. Feasibility was assessed by device usage and quality of tests.ħ3.7% felt that the HT was easy to use, and 100% found the HT useful. Patients were trained and instructed to bring two devices home for 1 week and use the HT 4 times/day for 4 days and the VF 3 times total.įor acceptability, we conducted satisfaction surveys and semi-structured qualitative interviews with thematic analysis. Prospective feasibility and acceptability studyĢ0 patients (39 eyes) with primary open angle glaucoma, open-angle glaucoma, ocular hypertension, or suspected glaucoma Our aim is to assess acceptability and feasibility of iCare HOME (HT) and Virtual Field (VF) in the home monitoring of glaucoma. Most participants were receptive to using video calling as a platform for teaching home tonometry. Most patients were able to perform home tonometry successfully when taught remotely, with a success rate similar to previously reported rates for face-to-face teaching using the same device. All participants were interested in continuing home IOP monitoring. All participants were happy with remote teaching, and none would have preferred training to be conducted face-to-face. 83% (10 of 12) obtained successful diurnal measurements at home. Participants had an average age of 60.1 ± 15.5 years. Questionnaires were used to evaluate perceptions on home tonometry and remote training. Successful participants were asked to take a series of home IOP measurements over 48 h. Following training, participants were asked to measure their own IOP, observed remotely by the optometrist. An optometrist conducted a 30 min live video training session via NearMe with each patient. Participants were provided with a rebound tonometer (Icare HOME) and instructions to attend remote teaching from home. This prospective study involved 12 patients with glaucoma attending an outpatient ophthalmology clinic. ![]() This project aims to determine the feasibility of teaching patients to perform self-tonometry remotely using a remote video link. The ICare HOME is a self-tonometer which empowers patients to measure their own IOP and allows a more complete picture of diurnal IOP. Intraocular pressure (IOP) is the primary modifiable risk factor in the progression of glaucoma.
