Alzheimer's disease and eye exams

-

Happy Friday everyone! It is currently cold and freezing rain, so a far cry from the 60 degree temps we enjoyed on Thursday. Such is life in the mid-west.

I have been aware of this for the last couple of years but an article hit USA Today on January 6th so I thought it would be good to discuss it briefly. First, just a little basic anatomy.  The retina is a direct extension of your brain. It is not an exaggeration to say we are looking at your brain when we look into your eye at the back of the eye where the retina is. It is obviously much easier and less expensive to look into the eye than look at your brain via an MRI or PET scan which can cost thousands of dollars.

Research is being done with a retinal scanning device called an OCT that would be able to pick up early changes in the retina consistent with the plaques that form in the brain with Alzheimer's disease. Imagine being able to run a simple, inexpensive (a couple hundred dollars) scan and determine if there is disease.

My personal opinion on this is that we will see this technology available in the years to come. We have a state of the art OCT at the office already and I would imagine it would be a software upgrade to the unit to run these scans. Time will tell of course, but I continue to be amazed at what we are able to see by looking into our patients eyes.

My contacts are poisonous? Not so fast.

       Recent media coverage has brought attention to a report claiming that 18 soft contact lenses from three major companies in the industry were found to contain PFAS or toxic "forever chemicals".  Per- and polyfluoroalkyl substances (PFAS) are a class of synthetic chemicals used in a variety of consumer products for their ability to resist heat, stains, and water. They are referred to as "forever chemicals" because they break down very slowly and can accumulate in people, animals, and the environment over time.  This has prompted concern about potential long-term health effects - studies have shown that high levels of exposure to some PFAS may be linked to increased risk of cancer and other adverse health issues.      In contact lenses, PFAS are used to soften the material and enhance oxygen permeability.  So, you might be wondering, are my soft contact lenses safe to be wearing?     Currently, there is no scientific literature published to show harmful effects

Eat Your Way to Better Eye Health If you’re like most people starting the new year, you may have made a resolution to eat healthier in 2023.  Whether you’re starting to fall off the wagon or holding strong, it’s never too late to start eating well.  There are several vitamins and nutrients specific to the health of the eyes, and chances are, what is good for the eyes is also good for your overall health. 1. Vitamin A     - Required for the formation of rhodopsin, a pigment found in the retina that allows us to see in low-light        conditions.  Deficiency could cause "night blindness" due to impaired dark adaptation.     - Supports healthy functioning of surfaces in the eye like the cornea and conjunctiva.  Deficiency could lead to        dryness and corneal scarring.     - Good sources : orange-colored fruit and vegetables like carrots, sweet potatoes, cantaloupe, and apricots. Eggs        and yogurt. Green leafy vegetables and liver. 2. Vitamin C     - Neutralizes damage

  The Scary Truth About Costume Contact Lenses This Halloween you may have seen some spooky contact lenses. Costume contact lenses, also known as cosmetic or decorative contacts, are lenses that change how your eyes look by altering the eye’s color or pupil shape. Even though they may be advertised as cosmetic accessories, please keep in mind that  all  contact lenses are considered medical devices by the FDA – this means they require a prescription and proper fitting by an eye care professional, and proper care by the wearer. Purchasing contact lenses without a prescription is illegal in the United States. Only buy costume contacts from retailers who ask for a prescription and sell FDA-approved lenses – not from the gas station down the street, your nearest beauty salon or pop-up Halloween shop. Some cosmetic lenses have been found to be counterfeit or even re-packaged, which is not sterile and could contaminate your eye. Furthermore, one study found costume lenses that tested positiv
