The participation in the study lasts for up to six months for each patient. This is made up of a baseline visit, and visits at one, three, and six months.
At each visit participants have their usual

Eligibility

All
Inclusion criteria
Inclusion criteria: 1. Patients with glaucoma of varying severity (mild, moderate and severe). The eligibility criteria are a diagnosis of glaucoma in one or both eyes (based on characteristic optic disc changes or glaucomatous visual field loss) 2. Visual acuity =6/12 vision 3. Aged =18 or above
Exclusion criteria
Exclusion criteria: 1. Patients with any significant non-glaucomatous conditions affecting visual function such as cataract, macular degeneration, retinal detachment, diabetic retinopathy, non-glaucomatous optic neuropathy 2. Eye surgery less than 3 months prior to recruitment, because testing of visual field shortly after eye surgery can affect test results. 3. Non-English speaking due to the voice prompt on the software is only available in English. 4. Non-elective hospitalization within the past 60 days that could be of concern in the investigator's judgment. 5. Significant non-visual impairment (eg mobility, verbal communication) preventing the completion of the objective. 6. Patients who are not able to provide informed consent.
Design outcomes
Secondary
| Measure | Time frame |
|---|---|
| 1. Reliability indices on visual field testing is measured using proportions of Fixation loss, False postive and False negative at all time points (baseine, 1 month, 3 month and 6 month visit) 2. Compliance with test-retest regimen is measured using proportion of visits attended at all time points | — |
Primary
| Measure | Time frame |
|---|---|
| 1. Accuracy is measured by comparison of visual field Mean Deviation (MD) and Pattern Deviation (PD) produced by Humphrey Visual field and Melbourne Rapid fields app using Pearson correlation statistics at all time points (baseline, 1 month, 3 month and 6 month visit) 2. Inter-sesssion reliability is measured using Blandt-Altman analysis comparing the test outcomes at all time points (baseline, 1 month, 3 month and 6 month visit) | — |
