Acuity Testing for the central 20º field
The Omnifield, available through Visoptics, is the first ever acuity field, the Omnifield measures visual acuity at fixation and at 24 intercepts across the central 20° diameter visual field. The device consists of proprietary software, a computer with wifi, an LCD monitor, a video camera to track eye fixation, a printer, and a specially designed, interactive response pad with a joystick and buttons. The patient is instructed to focus on a cross that is moved about the monitor turning on pursuit tracking that encourages fixation. The fixation is monitored by an infrared corneal reflex and pupil centrum eye tracker.
