Abstract

Purpose : Early detection of neovascular complications of age-related macular degeneration (AMD) is key to preserving vision. We consider compliance to weekly home monitoring of central vision with the Melbourne Rapid Fields (MRF) iPad app over a 12-month period and compared at-home results to in-clinic results.

Methods : We recruited participants with bilateral intermediate AMD, with access to an iPad (gen 2 or newer), for acuity and macular visual field monitoring in the home, on the tablet device. Visual acuity was measured to high contrast, low luminance and low luminance low contrast targets using Landolt C optotypes. Macular visual fields were measured out to 9.5°. Inclusion criteria were: BCVA better than 20/40 (6/12) in the test eye and the ability to understand English instructions as provided by the application. An in-office training session preceded the acuity and perimetry exams with the supervision of a clinical assistant. Participants were instructed to perform the exam unsupervised from home on a daily basis for the first 5 days (baseline) moving to weekly testing for the following 12-months. Email reminders were sent if participants had not performed a test after 2 weeks. If no further tests were performed after 3 weeks the participant was considered to have discontinued. Visual acuity was expressed as logMAR and visual fields were analysed by their mean deviation (MD). We compared in-clinic and at-home baseline performance with paired t-tests.

Results : Forty patients (70 years ± 7.6) were recruited. At 12-months, 22.5% complied with weekly testing, 52.5% returned a result at 2 weeks, 7.5% gave a result every 3 weeks (after email reminder), and 17.5% discontinued. At the end of the trial, 82.5% of patients were actively undertaking home-monitoring. On average, participants returned a test once every 13.0 ± 9.3 days. Common reasons for drop out were technical difficulties in downloading or operating the app, as well as finding time to perform the test. Home-monitoring returned baseline acuity and MD that did not differ from the in-office outcomes (p>0.05). However, variability at home was greater (x1.61) across all data sets (p<0.05).

Conclusions : Home-monitoring with a tablet perimeter is a viable option for patients with AMD. The greater variability will require increased test number to detect early change.
