FDA Approves Software For iPhone-Based Vision Test

anderzole writes "The FDA recently gave clearance to Vital Art and Science Inc. (VAS) to market software which enables people with degenerative eye conditions such as macular degeneration and diabetic retinopathy to monitor their vision at home with their iPhone. The software, which is called myVisionTrack, isn't a replacement for regular visits to the doctor, but rather allows patients to keep tabs on their vision in between visits with eye care professionals. VAS notes that retinal diseases affect approximately 40 million individuals worldwide and 13 million in the United States. While treatments have been developed to deal with degenerative eye conditions, early diagnosis is of paramount importance — which is why the software is so important."

Re:Why the large proportion of US citizens?

Because if you write a press release to try and talk up investors, you only talk about the SAM (serviceable available market), not the TAM (total available market) for your products. Here's the original source [myvisiontrack.com]...

Age-related macular degeneration (AMD), diabetic retinopathy (DR) and other retinal diseases afflict more than 40 million people in countries with advanced health care systems. Roughly 13 million people suffer from these diseases in the United States.

For example, the EU has roughtly 8 million people that suffer from wet-AMD and DR. If you have any of these diseases and you are in a country w/o advanced health care systems, you are simply classified as blind (which is the eventual outcome for these diseases). This software (even if it were available and worked), will not help folks that are unfortunate enough to live in a country where appropriate treatments are unavailable.

Sadly, with wet-AMD, there is no actual effective treatment today. There are some drugs known to slow the advance, of this disease, but not reverse it. With DR, there is some hope when reversing the diabetic aspect, but that is not really a great situation either.
