Perimetry, – the measurement of retinal sensitivity at different visual field locations–is an essential and often used procedure in ophthalmology. The most common technique for this is Standard Automated Perimetry. For various reasons, this technique is less suitable for use in various clinical populations. Therefore, there is a need for much simpler methods. In a recent paper in the journal Frontiers in Neuroscience, Alessandro Grillini and colleagues describe and validate the principles behind a very promising new approach for perimetry based on continuous gaze tracking. It requires the patient to do nothing more than to follow a moving dot with their eyes. Want to know more? You can find the paper here.
