Introduction
Virtual Visual Field, even though a cornerstone of glaucoma diagnosis, has always been a cumbersome and difficult test to administer as well as undergo. It was the only standard test to assess the functional damage due to glaucoma for several decades and had not evolved much despite rapid advancements in technology. This is now the era of Virtual Reality, and several innovators started to develop head-mounted visual field testing devices derived from gaming headsets including the extremely low-cost Google Cardboard.
Virtual Reality is an upcoming field and Perimetry is only one of the aspects of Ophthalmology being advanced by it. The Periscreener[1] developed out of a collaboration between Aravind Eye Hospita[2]l and Vellore Institute of Technology, essentially consists of a low-cost Google Cardboard headset, two ordinary android smartphones, and a Bluetooth clicker. It was crude and did only suprathreshold testing, but worked as a prototype.
VirtualEye[3] is a head-mounted, eye-tracking perimeter, that does the equivalent of a full threshold 24-2 visual field. In addition to manual patient response with a click, it can also do an innovative technique called Visual Grasp, where the eye tracker detects change in gaze as detection of stimulus. This mode utilizes the natural tendency to look at a new, moving, or transient visual stimulus. The hypothesis is that the M-cell system inputs to a reflex that, unsuppressed, drives an eye movement to acquire the novel target to the fovea. This mode does not require a manual input from the patient and does not require the cortical processing and decision making required for manual mode.
