Advancing Vision Restoration with Genes & Proteins
When it comes to our health, an ounce of prevention is worth is a pound of cure. Yet, despite a person’s best efforts, he or she could develop age related macular degeneration or retinitis pigmentosa. Is there a way to fix the internal mechanisms that lead to vision loss or even repair what is damaged […]
Advanced Lenses, Clearer Vision
Eyeglasses have been used to improve vision for close to 300 years. In 1936, optometrist William Feinbloom developed contact lenses made from a combination of glass and plastic. While most corrective lenses are used to help those with nearsightedness and farsightedness, they can also address other vision conditions. Light Adjustable Lenses Lenses known as intraocular […]
Vision Innovations for Diabetic Eye Disease
In the U.S., 38.4 million people have diabetes. Sadly, some of them will develop vision issues related to the diseases, such as a corneal infection known as keratitis or, worse, diabetic retinopathy. It is bad enough to have diabetes and all the complications associated with it. Is there a way to reduce the likelihood of […]
The Brain’s Inner Workings When It Comes to Vision
Vision isn’t as easy as it looks, pardon the pun. Images are coming into to the eye and going to the brain where they are interpreted by the person. Seeing the image spurs the person to move away, if it is an obstacle in their path. Conversely, the image can spur the person tor move […]
Charting Paths to Precision Eye Care Part Two
Part one covered research done at the University of Pennsylvania involving genetic analysis of persons of African ancestry related to glaucoma. Of course, genes aren’t the only place that may provide clues about glaucoma development. The macula may also show early signs of the disease. The macula is a part of the retina that is […]
Charting Paths to Precision Eye Care: Part One
According to the Centers for Disease Control (CDC), over 3 million people in the U.S. currently have glaucoma, and the disease costs the economy over $2 billion in losses in productivity losses and direct costs. Scientists are studying this disease to understand its causes and progression, as well as ways to detect it before symptoms […]
Screen Time—What’s Good. What’s Bad.
Screens are everywhere—from desktop and laptop computers to smartphones and tablets. Of course, spending too much time in front of a screen can lead to eye strain for adults. What about children and teens? Technology is second nature to them, and they spend a lot of time playing games on a tablet or scrolling through […]
The Science of Facial Recognition
Recognizing faces is a skill that humans and primates both have. When it comes to human infants, they tend to focus their gaze on faces. They do this before their eyes develop the ability to discern the features of a face and before the face-specific area of temporal cortex of the brain is fully developed. […]
Genetics & Their Effects on Eye Disease Part Two
What if it’s a modifier gene that causes problems with vision? What’s so troublesome about a modifier gene? It has a variant, such as a single nucleotide change, that differs from the common sequence. The variant doesn’t cause disease by itself, but it can influence the observable characteristics of a genetic disease through mechanisms that […]
Genetics & Their Effects on Eye Disease Part One
When it comes to many diseases, particularly eye diseases, genetics plays a role in the how and when a specific disease develops. Of course, it isn’t as simple as having X gene and getting Y disease. Lifestyle factors can influence certain genes. Also, the presence of modifier genes—genes that are slightly different, such as a […]
