The U.S. Food and Drug Administration has authorized use of an iPhone app to allow retinal disease patients to monitor their vision between visits to the doctor.

visiontrackMyVisionTrack was developed for elderly patients with serious retinal diseases, such as age-related macular degeneration and diabetic retinopathy. It incorporates a proprietary shape discrimination hyperacuity (SDH) test by the Retina Foundation of the Southwest, which developed an eye exam that’s suitable for a PC or smartphone and is unaffected by factors such as user distance.

The test consists of three circles, one of which is distorted, Mike Bartlett of Vital Art and Science (VAS) said. The app instructs patients to “touch the circle that is different,” he explained. “As they get it right, the distortion gets smaller; when they miss, the distortion gets bigger,” he said.

Then the test moves to the user’s threshold until the distorted circle is no longer visible. An algorithm determines a patient’s vision threshold using statistics generated by the app.

    I was wondering if you ever considered changing the layout of your
    website? Its very well written; I love what youve got to say.
    But maybe you could a little more in the way of content so people could connect with
    it better. Youve got an awful lot of text for only having one
    or two images. Maybe you could space it out better?
