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.

The Most Beneficial Foods for Eye Health

 

Drinking plenty of water, eating nutrient-rich foods, and exercising can improve our lives and increase health benefits. Eye health is also supported through these same activities. Regularly consuming specific vitamins and nutrients can prevent or delay sight-threatening eye conditions and diseases which include macular degeneration, cataracts, and glaucoma.

Fish: omega-3 fatty acids are present in oily fish such as tuna, salmon, trout, mackerel, sardines, anchovies, and herring. Studies have shown that dry eye can be reversed by fish oil consumption.

Nuts, seeds, and legumes: beyond omega-3 fatty acids, nuts also contain a high Vitamin E level, which can protect the eye from age-related damage. Examples include: Brazil nuts, hemp seeds, walnuts, lentils, flax seeds, cashews, chia seeds, and peanuts.

Citrus fruits: boasting high amounts of Vitamin C, an antioxidant that fights age-related eye damage, citrus fruits such as lemons, oranges, and grapefruits can improve eye health.

Leafy green vegetables: kale, spinach, and collard greens are highly beneficial for eye health since they contain lutein, Vitamin C, and zeaxanthin.

Carrots: beta carotene and Vitamin A are both highly present in this vegetable, and both play an essential role in eye and vision wellbeing.

Sweet Potatoes: getting their orange color from beta carotene just like carrots, sweet potatoes also contain Vitamin E, which is an antioxidant helpful to increase eye health.

Beef: high levels of zinc are linked to beef consumption, which can delay age-related sight loss and macular degeneration. The eye itself contains high levels of zinc, especially in the retina.

Eggs: lutein, zeaxanthin, Vitamin C, Vitamin E, and zinc are present in eggs. These are all vital nutrients to combat age-related vision loss.

Water: to reduce dry eyes and dehydration, drink plenty of water daily.

Try consuming these foods to increase your overall eye health. For more information or to ask a professional for advice regarding ocular issues, contact the specialists at Rohr Eye & Laser Center today.

Computer Vision Syndrome Signs and Remedies

 

The COVID-19 pandemic forced many people to work from home or remotely. As a direct result, the use of computers, tablets, phones, and other electronic devices has risen dramatically. A condition called Computer Vision Syndrome (CVS) can be caused by excessive screen time. Also known as digital/computer eye strain, this phenomenon occurs when the eyes aim towards a screen for lengthy periods. Even without the pandemic, monitors, screens, smartphones, and the like can contribute to computer eye strain.

The American Optometric Association (AOA) suggests following the 20-20-20 rule: take a 20-second break every 20 minutes to look at something 20 feet away. This strategy will help curb CVS symptoms, which include eyestrain, headaches, blurred vision, dry eyes, and neck and shoulder pain. Factors contributing to CVS are poor lighting, screen glare, improper viewing distances, poor seated posture, uncorrected vision issues, or a combination of these.

A comprehensive ocular exam will diagnose CVS. Treatment options vary; glasses, for example, are a good option for those suffering from CVS. Some lenses now come equipped with unique technology that blocks out blue light, which is thought to be emitted from digital screens. Glasses might need to be prescribed to meet the unique digital demands of computer viewing for individuals who do not otherwise have them. Eye focusing or coordination issues cannot be corrected with glasses or contact lenses. Vision therapy, a structured program of visual activities, is prescribed in those cases. The eye exercises train the eyes and brain to work together more effectively by strengthening rapid eye movement, focusing, eye teaming, and reinforcing the eye-brain connection.

Other factors, such as proper body positioning, come in to play when trying to correct CVS. Screens should be lower than eye level and be without glare (reduce lighting in the area to accomplish this or purchase an anti-glare screen.) Chairs should be comfortably padded, and feet are recommended to stay on the floor. Take frequent eye rest breaks (20-20-20 rule) and remember to blink frequently, which keeps the front surface of the eye moist.

To prevent CVS, ensure your glasses or contacts are the proper prescriptions. Minimize your exposure to blue light by purchasing blue-light blocking lenses. Adjust your work area for ultimate comfort, and take multiple breaks throughout the day. Anything that needs to be referenced from the computer screen should be placed as near as possible and at the same height.

Macular Degeneration Effects Reduced by Brain Stimulation

 

The University of Waterloo’s School of Optometry found that brain stimulation can assist in recovery of vision in people with macular degeneration. A single 20-minute session of non-invasive visual cortex stimulation resulted in improved effects in macular degeneration patients.

Peripheral vision is relied on heavily by people who suffer from macular degeneration, as they often lose central vision. When attempting to crowd or segregate an object from others in close proximity, further difficulties arise.

Transcranial direct current stimulation (tDCS) interventions reduce mechanisms in the visual cortex that contribute to crowding. This can improve vision in patients with central vision loss, especially when combined with perceptual learning techniques.

Ben Thompson, professor at the School of Optometry and Vision Science, said, “Perceptual learning can reduce letter crowding for patients with macular degeneration. However, perceptual learning typically requires intensive training, which may be a barrier for patients. Additionally, the learning does not always transfer to non-trained stimuli, that’s why this discovery is so promising, it addresses all of these concerns. Results of this study lay the foundation for future work investigating whether a-tDCS may be useful as a visual rehabilitation tool for individuals with central vision loss who are reliant on peripheral vision.”

Macular Degeneration is the leading cause of vision loss (more than cataracts and glaucoma combined), affecting more than 10 million Americans. It is considered an incurable eye disease caused by the deterioration of the central portion of the retina. The retina is the inside back layer of the eye that records the images we see and sends them to the brain via an optic nerve. The macula, the retina’s central portion, is responsible for focusing central vision in the eye. It also controls our ability to read, drive a car, recognize faces, colors, and see objects in fine detail.

There are three stages of macular degeneration, with vision loss as the last. Despite there being no cure for macular degeneration, activities such as dieting, exercising, avoiding smoking, and protecting your eyes from ultraviolet light are all ways to decrease the overall risk.

For more information regarding the correlation between macular degeneration and brain stimulation, read the original article. Contact the professionals at Rohr Eye & Laser Center to experience personalized ocular care.
