Data description (abstract)

Perimetry is an important technique for managing a range of visual system disorders. In order for a perimetry test to be accurate, it is essential that patients keep their eyes fixed on a central target. This means that visual field testing in patients with highly unstable fixation (e.g., nystagmus) might be inaccurate. To investigate this, we have built our own visual field instrument that uses a high-speed eye tracker and gaze‑contingent examination to compensate for unstable eye movements. We compared the test-retest variability of our visual field instrument against conventional methods in normally-sighted observers and demonstrated that variability is unaffected by gaze-contingency, providing proof-of-concept for the instrument’s use.
