When the Rods & Cones Need Fixing

The rods and cones in the retina do a lot work when it comes to vision. Rods are sensitive to changes in light and dark, as well as shape in movement. Cones are sensitive to one of three colors, red, green and blue, and can detect fine details. If the rods and cones aren’t working […]

Two Additional Reasons to Get an Eye Exam

Everyone agrees on the importance of regular eye exams. After all they are good for vision correction, eye disease prevention and vision maintenance when a person has a condition like glaucoma. Now you can add improving gut health and preventing heart attacks by way of an eye exam. Gut Health via the Eyes Chronic noninfectious […]

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 […]

Advances in Bionic Vision

If you are of a certain age, you will remember a television show from the 1970s called “Six Million Dollar Man”. The show was about an Air Force Colonel Steve Austin who is seriously injured when a spaceship he is testing crashes. He then has surgery where he receives bionic legs, a bionic left arm […]

Usher Syndrome

Usher Syndrome is a rare, inherited condition that affects the three major senses, vision, hearing and balance. There are three types and they are: Type 1—This causes profound deafness at birth, balance dysfunction and progressive vision loss. Type 2—This causes moderate to severe hearing loss at birth and progressive vision loss. Type 3—This causes later […]

Optical Illusions

Optical illusions are intriguing and sometimes baffling. In the 1990s “Magic Eye” pictures were everywhere, from mall kiosks to the back of cereal boxes. The “Magic Eye” were pictures that were distorted in such a way that a 3D image would over time appear to the viewer. The image never appeared to me, no matter […]

I’ve Seen That Before—How the Brain Discerns What is Familiar vs What is Novel Part Two

The study at MIT looked into the brain’s visual recognition memory to learn how it focuses on what’s new and ignores what isn’t. A study at the University of Pennsylvania looked at the theory of repetition suppression, namely that less activity in the inferotemporal (IT) cortex meant that the image in question was familiar. The […]

I’ve Seen That Before—How the Brain Discerns What is Familiar vs What is Novel Part One

As we go about our day, our eyes are taking in a lot of images and our brain is processing them all. The images range from the familiar to the novel. Once these images come into the brain, how are they processed so that we know what familiar and what is novel. Two research projects, […]

The Genes Have It

Genetic research has revealed many things about eye diseases. Two studies in particular have revealed how gene variants in inherited retinal dystrophies (IRDs), such as retinitis pigmentosa, lead to these diseases and how gene therapy can help preserve vision. Whole-Genome Sequences Researchers at the University of California San Diego School of Medicine and at Shiley […]

Automation Comes to Eye Imaging

Aren’t optical coherence tomography (OCT) machines great? The machine uses light waves to take a cross-section of the retina and this allows the eye doctor to map and measure its thickness. These measurements help with the diagnosis and treatment of glaucoma, age-related macular degeneration (AMD) and diabetic eye disease. As great as an OCT machine […]
