Dr. Mark Baron, director of the Southeast Veterans Affairs Parkinson's Disease Research, says the disease starts a one to three decades, before patients start having motor symptoms. He believes his eye test is the key to early diagnosis.
According to Dr. Baron, everyone with Parkinson's disease has a tremor behind the eyes. While wearing his device, patients follow a dot on the screen that tells the eye tracker where he is looking. Doctors then analyze the data looking for the tremors.
Dr. Baron says in a matter of minutes the test shows whether a patient has Parkinson's. It can also help reverse a misdiagnose.
He'd like to see the eye test become a screening tool used during regular doctor visits. He says it could also help detect movement disorders, other than Parkinson's disease.
