Night Vision Tests and AI Part One
The two forms of age-related macular degeneration progress at different rates. The wet form of the disease progresses faster than the dry form. Still regardless of the type, once someone is diagnosed with age-related macular degeneration, that person can expect a decline in vision to take place gradually over the course of five years. In […]
Light and Dark
While it is difficult to do near work like reading, writing or certain crafts like needlepoint, in low light, for the most part our eyes adjust and we can maneuver in the space or at least find the light switch. How does our eyes and brain work so that we can see both in low […]
Newts and Zebrafishes—Oh My!
A little over 100 years ago, scientist were studying fruit flies to learn more about genetics. Since they were easy to capture and breed, scientists were able to study multiple generations in a short period of time. The information that they found lead to the mapping of regions that correspond to the fly’s physical traits. […]
Peripheral Vision & Crowds
Peripheral vision and navigating through crowds, what do they have in common? For the most part nothing. Yet they are two examples of how information from the eye is coming into the brain and is being processed so that we can act accordingly. Two studies, one at the National Eye Institute (NEI) and the other […]
Detecting & Fixing Eye Diseases
In eye diseases like retinitis pigmentosa, age-related macular degeneration and Leber congenital amaurosis, things are going on in the cellular level that occur before anything is detected by way of a test or observation. It would be great if these changes could be detected sooner and if there was a way to stop the deterioration […]
Changes in Technology Lead to More Info about Vision Diseases
If you are of a certain age, you will remember that in the 1980s first mobile phone were car phones. In fact, they were something of a status symbol, since they weren’t cheap. So, executives and high-end real estate agents were the ones who most likely had a car phone. Well, thanks to advances in […]
Geographic Atrophy in AMD
Geographic atrophy (GA) is an advanced form of age-related macular degeneration (AMD) that affects the retina. Those with GA can have good vision if the macula, the center part of the retina responsible for sharp, central vision, isn’t damaged. While there are ways to assess the how well different therapies are working, visual acuity tests […]
AMD Research News
Age Related Macular Degeneration (AMD) is a vision condition that no one wants. As the name suggests, this affects persons over the age of 50. It comes about when the macula, the part of the retina that controls sharp, straight-ahead vision, becomes damaged over time. While it doesn’t lead to total blindness, losing central vision […]
Visual Development
It is well known in the medical and scientific fields that newborn babies can’t see very well. Initially, all they can make out are faces. Everything else is a blur. As their eyes grow and brains develop, their vision improves. How does that process take place? Do changes in the process lead to visual impairment? […]
Visual Processing Part Two
Since it was identified which cells do what for vision, the next question is what part of the brain is in charge of processing visual information? Vision is more complicated than it seems. For the longest time, it was thought that vision was a matter of an image that is cast on the retina and […]
