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 […]

Cataracts and the Zika Virus Affect Vision Development

When babies are born, they can see an object with their peripheral vision but their central vision is still developing. Over the first few weeks, as a baby’s retina develops, his or her pupils widen and the baby can see light and dark ranges and patterns. At one month, a baby may briefly focus on […]

Research

Thanks to biomedical research, our understanding of the human body is evolving and this has led to treatments that improve health outcomes. This includes vision research and as a result, more is being learned about what leads to amblyopia and a possible treatment for age-related macular degeneration (AMD). Amblyopia Amblyopia, also known as lazy eye, […]

On/Off Switches Part One

Isn’t electricity great? You flip a switch and an appliance turns on or off. Wouldn’t it be nice if there was a way to do something similar for our bodies, in particular our eyes. That way when an injury or disease comes along, something in the cellular level could be turned on or off and […]

Immune System & Eye Disease: More than Meets the Eye

Having an immune system is a good thing. It deals with bacteria and viruses, so that either we don’t get sick or if we do, our body fights them off and, for the most part, sickness isn’t fatal. Sometimes our immune system doesn’t work the way we want it to. That can range from an […]
