Eye lens from patients’ own stem cells, restoring vision

Eye lens from patients’ own stem cells, restoring vision

  Lens regeneration in monkeys after minimally invasive surgery. Slit-lamp microscopy showed regenerating lens tissue grew from the peripheral to the central lens in a circular symmetrical pattern 2–3 months after surgery, reaching the center at 5 months post-surgery; direct illumination showed that the visual axis remained translucent. (credit: Haotian Lin et al./Nature)   Researchers at University of California, San Diego School of Medicine and Shiley Eye Institute, with colleagues in China, have developed an eye lens restoration treatment that has been tested in monkeys and in a small ...

How your eyes work

Complex eyes can distinguish shapes and colours. The visual fields of many organisms, especially predators, involve large areas of binocular vision to improve depth perception. In other organisms, eyes are located so as to maximise the field of view, such as in rabbits and horses, which have monocular vision. The first proto-eyes evolved among animals 600 million years ago about the time of the Cambrian explosion. The last common ancestor of animals possessed the biochemical toolkit necessary for vision, and more advanced eyes have evolved in 96% of animal species. Here is a brief video that e...

Diabetic Retinopathy Treatment

Diabetic Retinopathy Treatment The retina is the layer of the eye that is directly in the back of the eye. The retina sends the images that are seen to the brain. As we review in our previous post Diabetic Retinopathy is a disease of the retina. Many people who have diabetes will eventually get Diabetic Retinopathy. Diabetic Retinopathy can cause vision failure and lead to blindness. It usually gets worse over time. It affects the blood vessels in the eye causing them to weaken, which can lead to blood and liquids leaking into the retina. This is the common type of Diabetic Retinopathy.   D...

How the eye evolved?

How the eye evolved?

John Doe 17/05/2016 0
Eyes are so complex that some say natural selection couldn’t possibly be how they formed. So, how did eyes evolve?   "The eye to this day gives me a cold shudder," Charles Darwin once wrote to a friend. If his theory of evolution was everything he thought it was, a complex organ such as the human eye could not lie beyond its reach. And no one appreciated the beautiful construction of the eye more than Darwin—from the way the lens was perfectly positioned to focus light onto the retina to the way the iris adjusted the amount of light that could enter the eye. In The Origin of Species, Darwin ...

An eye exam could help save your life

An eye exam could help save your life

A comprehensive eye exam can do more than test your vision – it could help save your life. Eye exams with a doctor of optometry can help detect eye diseases and serve as early indicators of a number of potentially serious health conditions, including brain tumours.   It’s important to remember that the eyes are connected to many other systems in the human body. That makes routine eye exams an important part of preventative healthcare—regardless of your age or physical health.   Comprehensive eye exams not only test your vision, but also give optometrists a close-up look at the inside of th...

If you have diabetes, your blood glucose, or blood sugar, levels are too high. Over time, this can damage your eyes. The most common problem is diabetic retinopathy. It is a leading cause of blindness in Canadian adults. At Grande Prairie Eye Care we take care to examine your eyes thoroughly. Your retina is the light-sensitive tissue at the back of your eye. You need a healthy retina to see clearly. Diabetic retinopathy damages the tiny blood vessels inside your retina. You may not notice it at first. Symptoms can include Blurry or double vision Rings, flashing lights, or blank spots ...
