Rapid Campimetry (RC): 
RC is a novel, kinetically based (with moving stimuli as opposed to stimuli at fixed test locations) perimetric technique that tests the central 30 degrees of the VF for areas of absolute functional l
SPP focuses on functional assessment in end-stage glaucoma by incorporating test points in the peripheral field, an area overlooked by SAP, which only probes the central 30 degrees of the VF. These pe
FST uses flashes of light to estimate the visual threshold of the entire retina simultaneously. Although it does not provide location-specific VF information, FST is particularly useful for patients w
Goldmann perimetry is the predecessor of the currently widespread SAP, where suprathreshold kinetic stimuli are moved gradually from outside the visual field towards the centre and the boundaries of t

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| For each test, the test score will be normalised on a 0 (blind) to 100% (normal vision) scale and a response curve (mean test score as a function of disease stage) will be made. The main endpoint of the study is the X50 point (the point along the response curve with a mean test score of 50%) and the slope of the response curves (defined as as the rate of change in test score per unit increase in disease severity at the X50 point) of the five alternative techniques. | — |
