Abstract

Objective

Our aim is to assess acceptability and feasibility of iCare HOME (HT) and Virtual Field (VF) in the home monitoring of glaucoma.

Design

Prospective feasibility and acceptability study

Subjects

20 patients (39 eyes) with primary open angle glaucoma, open-angle glaucoma, ocular hypertension, or suspected glaucoma

Methods

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.

Main outcome measures

For acceptability, we conducted satisfaction surveys and semi-structured qualitative interviews with thematic analysis. Feasibility was assessed by device usage and quality of tests.

Results

73.7% felt that the HT was easy to use, and 100% found the HT useful. 100% felt that VF was easy to use, and 94.4% found the VF useful. 100% of patients obtained an acceptable IOP and completed a VF test at home. We identified 4 key themes with 33 subthemes. 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.

Conclusion

HT and VF were acceptable and feasible in a small cohort of motivated subjects. 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. Home monitoring may also improve upon glaucoma care by enhancing patient empowerment and fostering community bonds. VF should be further evaluated to ensure validity.
