visualFields Easy is designed to use the iPad screen to perform a fast screening test of the visual fields (peripheral vision).
Visual field loss can be found in diseases such as glaucoma, stroke, multiple sclerosis and diseases of the retina.
This App uses the supra-threshold method of visual fields testing to detect gross abnormalities in the visual field.

*** This App is designed to be used by clinicians for a fast screening test of visual field in clinic or bed-side. ***
*** Now you can connect your iPad to a BlueTooth keyboard and use the keyboard keys to respond***
