Abstract
Purpose :
The primary aim is to determine long-term retention of glaucoma patients to the request for weekly home-monitoring (HM) of visual field. A secondary aim considers test reliability and concordance to in-clinic outcomes.
Methods :
Participants with stable glaucoma in one eye performed HM over a 12-month period using the Melbourne Rapid Fields-glaucoma iPad application (MRFg). Loan iPads with broadband connection were provided for a weekly test schedule with text message reminders. Participants attended 6-monthly clinical reviews. Monthly retention (28+1 days), test reliability (false positives and fixation loss <33%), and concordance to Humphrey Field Analyzer (HFA) outcomes were determined. Diagnoses based on linear trends (MRFg mean deviation vs HFA Guided Progression Analysis (GPA)) were compared to the clinical diagnosis of an ophthalmologist (chi-square analysis).
Results :
Eighty-five eyes of 47 participants with a mean age±SD of 64±17 years were enrolled. Forty subjects (85%) had successful uptake (≥1 test) with 58% active after 12-months. Retention to HM was 97% after weekly reminders with 77% of results reliable. Progression (≥1.25dB/yr) was identified by HFA-GPA in 3 eyes after 30 months and MRFg linear trend in 4 eyes by 3 months. Two of these eyes from both devices were classified as changed by the ophthalmologist (agreement =96%, χ2 (3,37)=13.5, p<0.01).
Conclusions :
HM over 12-months was sustained in 58% of volunteers with excellent monthly retention (97%). The high volume of tests returned by HM provides good concordance with in-clinic assays identifying 2 cases of progression early. HM should be considered for all high-risk cases of glaucoma.
