Establishing whether Glaucoma patients are stable or are experiencing progressive damage in the Visual Field has long been one of the most challenging problems faced by eye specialists, now you can do it by yourself at home. VisionField is used by to check if the eyes Visual Field is stable or it is worsening. As the nerve fibers in the optic nerve 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. In order for the results to be meaningful, we must be able to reproduce the circumstances of the test. In other words, the procedure must be standardized.
VisionField offers you an easy way to check by yourself your eyes Visual Field condition performing tests similar (although less complex ) to those run by the Humphrey® Field Analyzer. VisionField does not replace the methods that ophthalmologists use to check the Visual Field, but complements them.
