The Growing Technology of Retinal Implants

Submitted by spertsovsky on Sun, 05/13/2018 - 16:22

Retinal prostheses, or retinal implants, are a type of technology meant to help restore vision in patients with blindness or partial vision loss caused by retinal degeneration. This method is constantly being clinically tried and developed, and still has a long ways to go before it is a perfect solution to blindness. The surgical procedure involves microelectronics and microchip electrodes implanted into the back of the eye to restore the function of damaged photoreceptors, the light activated cells in the retina.

The Visual Effects of Fear and Anxiety

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. 

Eyeing Cardiovascular Risk Factors

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. 

Mission Accomplished- Interactive Retina Model

Submitted by laurenplozano on Wed, 04/25/2018 - 13:25

What a year it has been for the Arizona Retina Project! I am so grateful to have had the opportunity to work on Dr. Erika Eggers’ eye education and outreach project. Not only did I gain a newfound knowledge on the eye, but I learned how to communicate that information to the public, as well as how to show them through demonstration.  

 

Bacteria that Live on Our Eye Helps Protect Against Infection

Submitted by pazm1 on Thu, 04/19/2018 - 17:51

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.

Phase 1 Clinical Study for Stem Cell Derived Treatment for wet AMD

Submitted by keerthikurian on Mon, 04/09/2018 - 13:34

 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.

Ebola's Lasting Legacy- Blindness in Survivors

Submitted by pazm1 on Thu, 03/15/2018 - 17:10

 You would think that if a person managed to survive Ebola that it would be the end of the disease. Unfortunately, that is not the case. There are some persistent medical effects on their bodies including joint pain, headaches, and uveitis. The 2014-2016 outbreak of Ebola in Africa was the largest number of cases we had ever seen before since Ebola was recognized. The improved techniques with dealing with Ebola meant we also now have the largest number of survivors ever recorded.
