Purpose: To determine patient compliance and perfor- mance of in-home visual field testing using a tablet device over a 12-month period.

Methods: We recruited participants with stable glau- coma in at least one eye. All cases had 3-5 reliable Humphrey Field Analyser (HFA 24-2) outcomes that encompassed the follow up period of home testing. Test subjects were trained on the use of the Melbourne Rapid Fields-glaucoma (MRF-g) iPad application, guided by audio instructions. Volunteers were tasked with weekly testing for 12-months. At study completion, retention and compliance to weekly testing (7±1 days) was determined. The concordance of In-home MRF-g and In-clinic HFA trend was considered against clinical diagnosis

Results: Forty-seven participants (n = 85 eyes) with a mean age of 64 ± 17.1 years were enrolled. Compliance to weekly testing in this group was 73%. In-home results showed high degree of correlation with HFA results (R = 0.85 for mean deviation). There is fair (76%) agreement between trend analysis using In-home results and HFA result (Kappa = 0.21). Two cases had glaucoma progression during the 12-month period, both of which was detected by in-home testing (89% agreement, Kappa = 0.40).

Conclusions: Glaucoma participants showed good level of adherence to home monitoring of their visual field over 12-months. The larger number of visual field tests available using in-home MRF-g allowed detection of glaucoma progression in a relatively short period of time.
