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. The U.S. Food and Drug Administration has approved use of the MyVisionTrack iPhone app from Vital Art and Science (VAS), an ophthalmic medical device company, to allow patients to monitor their vision in between visits to the doctor. MyVisionTrack 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, Mike Bartlett, president of VAS, told eWEEK in an email.
