The RightEye Vision System: A Tool to Diagnose Parkinson’s Early?

On December 3, 2019, the FDA granted a Breakthrough Device Designation for the RightEye Vision System to help with early diagnosis of Parkinson’s disease (PD).1 Depending on how well the device works when it is tested and used at larger scale, this could be good news for the Parkinson’s disease community.

PD is a chronic, neurodegenerative disease that affects your movement. It tends to be very difficult to diagnose, particularly during early stages, when people experience fewer symptoms. That means the disease is generally far along by the time most people develop noticeable movement and coordination problems.

If healthcare providers had tools for earlier diagnosis, we might better understand how the disease develops, what treatments might be useful, and possibly how to prevent permanent neurological damage and movement disruption.”2

What is the RightEye Vision System?

A medical device designed to detect tiny eye movements, the RightEye Vision System was approved for use by the FDA in October 2018.3 The device is approved to record, view, and analyze eye movements as a way to identify certain visual problems in people with Parkinson’s.

The data collected by this system has helped doctors identify eye movement abnormalities that can be a sign of neurological or eye movement disorders. These include brain injuries and concussions, but they have to potential to identify Parkinson’s, as well.”3

What is the Breakthrough Device Program?

The Breakthrough Device Program is offered by the FDA as a way to speed up the development and review of certain medical devices that might offer more effective treatment or early diagnosis of irreversible or deadly diseases.4 The program allows people with Parkinson’s early access to these devices while they are still being tested. If the new devices are approved by the FDA as being safe and effective, the devices can be sold to the public.5

How do eye movements connect to Parkinson’s disease?

Data shows that people with PD often experience tiny tremors in their eyes. RightEye may be able to detect these tremors, which might help doctors diagnose Parkinson’s disease. Eye tremors are detectable way before other more obvious movement problems develop. So being able to test for them might provide a reliable technique for early diagnosis of Parkinson’s.”3

Benefits of early diagnosis of Parkinson’s disease

There is no single test to diagnose Parkinson’s disease. The disease is generally diagnosed once motor symptoms appear. But by then it has already progressed substantially. Research shows that 60 percent of people with Parkinson’s are misdiagnosed at least once. One-third are misdiagnosed twice.1

“With this FDA Breakthrough Device Designation, RightEye has an opportunity to address a critical unmet need in the fight against Parkinson’s disease,” said to Adam Gross, co-founder and CEO of RightEye. “The annual cost of Parkinson’s disease in America is estimated at approximately $52 billion. Earlier assessment, intervention, and more accurate diagnoses, is anticipated to reduce these costs, while also improving patient outcomes and quality of life.”3

    While I’ve had serious tremors in my hands for 3 or 4 years (about 3 years ago our younger cat (my feline nurse who’s on my lap comforting me as I write this) was put on a medicine that has to be squirted in her mouth each day. The two times I tried doing it, about half the medicine squirted on to the floor due to my hand shaking, so Patti’s been giving her the medicine ever since. But our newspaper just had an article on PD symptoms, and I have several. (The one about moving around a lot in our sleep is something Patti’s talked to me about for 2 or 3 years.) But what scares me the most is I have been diagnosed mild cognitive impairment, a precursor to all dementias. I have an appointment with my neurologist next month, but to say I’m concerned is a vast understatement.) But I am going to ask for a right eye test, even if I have to go to California. (We live in NJ.) All the best to everyone who has PD. (BTW, I’m a moderator for, my first BIG health battle, but to me child’s play compared to PD.) Len Smith

    Hi, Len – Great to hear from you. I can certainly see your concern regarding the symptoms and MCI you’re experiencing. I hope it doesn’t take going across the country to get some answers! Please keep us updated with what you find out. Appreciate all you do for the Prostate community. Take care. – Chris, Team

    Who has access to the right eye tests as of right now, and where can we go to have this test done.
