Early Detection of Parkinson’s Disease Possible from an Eye Exam

 

Artificial Intelligence (AI) machine learning technology in addition to a simple eye exam could detect early signs of Parkinson’s disease, according to research presented by the Radiological Society of North America (RSNA).

A progressive disease of the central nervous system, Parkinson’s affects millions of people across the world. Tremors, muscle stiffness, and impaired balance are generally key markers of the disease. Once these symptoms are present, patients are already experiencing significant disease progression. Parkinson’s disease also affects the microscopic blood vessels in the retina. These markers provide an opportunity for AI to inspect images of the eyes for signs of the disease meticulously.

In a study by the University of Florida, researchers enabled an AI machine to analyze photographs of the back of the eye in two patients with Parkinson’s disease and two control participants. The AI was a type of Support Vector Machine (SVM) that has been around since 1989.

The SVM AI was able to classify Parkinson’s disease based on the blood vessels in the retina. Smaller blood vessels showed that changes in brain physiology can be detected in the eye. This novel discovery varies from the more traditional approach of diagnosing Parkinson’s disease.

With an overall goal to catch Parkinson’s disease cases sooner in its progression, researchers believe the new AI technology will help them better understand the disease on the path to finding a cure or slow its progression.

Moreover, other diseases that affect brain structure, such as Alzheimer’s disease and Multiple Sclerosis, could be identified in the future.

Eye Damage from Glaucoma Reversed in Mice

 

Scientists from Harvard Medical School have successfully restored vision in old mice by “reprogramming” cells to a younger state in which they can fix or replace damaged tissue. This accomplishment is the first to show it might be possible to safely reprogram complex tissues to a previous state. The researchers successfully reversed eye damage from glaucoma in mice; glaucoma is the leading cause of blindness worldwide. Notable retina benefits included nerve regeneration and reversal of vision loss in animals with and without glaucoma.

Further studies will undoubtedly pave the way for tissue reprogramming to be tested on other organs, thereby reversing age-related diseases in humans. Further studies remain to be replicated prior to human experimentation; however, this novel discovery paves the way for reversing age-related human ailments.

The researchers theorized aging results from cells within the body containing the same DNA molecules but drastically varied roles. These cells only read genes specific to their type. The theory suggests that changes can cause cells to read the “wrong” genes and malfunction, which in turn causes the aging process to decline/reverse.

Aging reduces the efficiency of all cells and organs in our bodies; our brains are no exception. Circuit-forming neurons can adapt to change, regenerating in response to injury. This process weakens over time, which has long been known, but how these shifts lead to deterioration is still unknown.

Eye conditions that damage the optic nerve can result in glaucoma. Without healthy optic nerves, blindness can result. Abnormally high eye pressure is usually the cause of significant impairment. One of the leading causes of blindness in people ages 60 and up is glaucoma. The absence of specific warning signs combined with a gradual effect is usually a perfect storm for glaucoma’s presence to be noticed at an advanced stage.

There are many risk factors to consider regarding glaucoma; additionally, preventative measures can be implemented to ensure vision loss is not taking place or worsening.
