Establishing whether Glaucoma patients are stable or are experiencing progressive damage has long been one of the most challenging problems faced by eye specialists, now you can do it by yourself at home.

The VisionField application was developed to be a small tool that can be used by people with already diagnosed Glaucoma to check if the eyes Visual Field is stable or it is worsening.

As the nerve fibers in the optic nerve (The cable that transmits the visual messages from the eye to the brain.) are damaged in Glaucoma, there is a gradual and painless loss of vision. Initially, glaucoma affects peripheral (side) vision.

The loss often goes unnoticed. However, if untreated, glaucoma may eventually affect central vision, as well. Usually it is only with this more advanced stage of Glaucoma that one can recognize loss of vision without special tests.

VisionField offers a simple way to measure the extent and light sensitivity of our visual field at any given moment. This is accomplished by increasing the intensity of a stimulus to a known area of the retina until the stimulus is seen.
