Now that summer is in full blast here in Arizona, it is easy to forget that just because we are used to the heat, we can't take shortcuts when it comes to our health. The sun can be very dangerous, so of course it’s important to wear lots of sunscreen to protect your skin, but it’s also just as if not more important to protect your eyes!
Everyone experiences some form of anxiety throughout daily life. For some, it may be moments of fear due to exposure to some sort of threat. For others, it can be a disorder that affects their daily lives, and it may not have any apparent cause. When a person experiences anxiety, they may have a wide range of symptoms, some of which could include changes in vision. None of these symptoms will cause lasting damage or blindness, but they can be frightening to experience.
Researchers were able to use semi automated software to look at pictures of the retina in peoples eyes, and associate the state of the retina with things like cardiovascular disease, stroke, chronic kidney disease, and mortality.
This was done by using a deep learning algorithm- which is a machine learning method for data extraction and transformation. Deep learning has been used in cases where the software was able to detect diabetic retinopathy and related retina diseases, along with tuberculosis, and melanoma.
For years researchers have known that the bacteria, fungus, and other microbes that live in and on our body are often beneficial for our health, but until now there has been no proof that there are any that lived in the eye. Scientists with the National Institutes of Health's National Eye Institute published a paper, in Immunity, on Corynebacterium mastididis (C. mast) which has been found to be a resident commensal bacteria in mice eyes.
Wet Age related macular degeneration (AMD) is an issue in which new blood vessels grow in the choroid layer (right outside of the retina). These blood vessels are weak and leak fluid which gets into the layers of the retina and macula. The macula is a pigmented area near the center of the retina. The macula is responsible for central vision.
A few questions may come to mind when you see this picture and we’re here to answer them!
What’s on Sam’s face?
Sam has electrodes on her face that are used to detect electrical signals.
Why is Sam measuring electrical signals on her face?
Vision therapy is eye focusing exercises that help eyes’ convergence ability, which is your eye’s ability to take the two images your eyes are sending to the brain and put them together and make a whole image. It is a treatment for children for a condition called convergence insufficiency. If you are wondering what an eye focusing exercise one example would be pencil push-ups. Pencil push-ups are when a person focuses on a small letter on the side of pencil. Then slowly move the pencil closer to your face until you see a double vision. At that point stop and start again.
Obstructive Sleep Apnea (OSA), is a condition that is highly prevalent in today's society. It is a chronic disorder associated with shallow or paused breathing, and snoring during sleep, and sleepiness dring the day.
