Developing a visual perimetry test based on eye-tracking: proof of concept

Computerized Perimetry (CP) is one of the clinical tests commonly used to evaluate peripheral vision and monitor the progress of eye diseases such as glaucoma. The aim of CP is to determine retinal sensitivity using luminous stimuli of variable intensity at different positions of the visual field. In modern campimetry devices, patients must respond to each perceived stimulus by pressing a button; however, this characteristic makes the test more susceptible to spurious and erroneous interpretations due to tiredness, lack of concentration, or device design flaws. This work presents an alternative paradigm for automatically assessing stimulus perception through a low-cost eye tracker and a computer monitor. We tested the preliminary version of the paradigm among eight subjects and obtained favorable results. In conclusion, our eye-tracking paradigm tool could help design more reliable visual field tests using low-cost portable equipment.
