This ergonomically designed handheld device features 4 peripheral porthole LEDs (Light-Emitting Diodes) and 4 central porthole LEDs with a constant brightness.
The peripheral porthole lights test for peripheral suppression; the central porthole lights test for foveal fusion/suppression.
A momentary rocker switch allows for peripheral or central testing.
The discs in the magnetic version are encapsulated in a sealed clear plastic box. The patient selects the discs using a magnetic pen to move them into a scoring area. When complete, scoring is easily accomplished by reading the scores through the bottom of the box. Tip the box and shake the discs into the selection area for the next patient!
Color testing becomes a game so that adults and children as young as 4 years old are much more engaged!
