According to several studies patients have visual complaints from 2 to 10 years before some types of optic nerve diseases were diagnosed.
If optic nerve diseases are detected early, visual loss may be reversible.
Red Desaturation is known to be a good indicator of neurological visual field defects.
This test may be taken even if retention of acuity and/or form perception are affected.

Patients with non-specific visual/vision loss should be checked for visual field defects by means of red desaturation test and central vision test.

The Red Desaturation Test is made with the best of intentions. The intuitive and flawless design allows you to navigate easily through the application. The voice guidance is provided during the test so that you don't need to move your mobile device near or far to read the instructions but instead you can hear the nice voice guiding you through different steps and actions. The voice can easily be muted and unmuted.

In the test one should identify if the given red areas have the same rich red color or the colors appear more desatured pink or orange. At the end of the test results will show whether the person may have neurological visual field defects or not for each eye separately.
