Diagnosed prevalent cases of age-related macular degeneration (AMD) in the seven major markets—U.S., France, Germany, Italy, Spain, U.K., and Japan—combined is expected to increase from 33.66 million cases in 2021 to 40.32 million in 2031, at an annual growth rate (AGR) of 1.98 percent, according to GlobalData
, a leading data and analytics company. AMD is a progressive eye condition that is characterized by the gradual deterioration of the macula, which is the area of the retina responsible for central vision.

A retinal exam may be able to predict a person’s risk of heart attack, when combined with other information, according to a recent study. Researchers found that the pattern of blood vessels in the retina could help identify those who are likely to experience heart problems, according to The Guardian.
In a recent article posted on WebMD
, writer Carolyn Crist reported that the researchers used data from UK Biobank
, which contains medical and lifestyle records for 500,000 people, to calculate a measure known as fractal dimension. The research team then studied people in the database who had experienced a heart attack, or myocardial infarction, after retinal images had been collected, Crist said.

Along with receding hairlines, crow’s feet and sagging skin, presbyopia is one of the least welcome physical changes we experience as we age. The gradual loss of our eyes’ ability to focus on nearby objects, a result of the stiffening of the crystalline lens, is an inevitable condition for most of us who are middle aged and older. In fact, you could even add presbyopia to the familiar litany of death and taxes. And it only gets worse with time.

While researching and writing a feature article on presbyopia for the June issue of Vision Monday,
I remembered a novel device called the Grolman Fitting System that was once used for fitting patients with progressive lenses. It was, excuse the pun, progressive for its time, though it has since been replaced with modern, digital technologies. Here’s a brief history of the device, drawn from an article I wrote about 25 years ago.

I’m always on the lookout for new research that help us better understand human vision as well as how to preserve and protect it. One study that caught my attention recently concerns a team of researchers at Purdue University
who discovered that the circadian clock plays a significant role in protecting eyes from retinal degeneration. The team studied fruit flies, which serve as a good model for the human retina. In a recent interview with Purdue writer Elizabeth K. Gardner, team leader Vikki Weake, associate professor of biochemistry in Purdue's College of Agriculture, discussed how it might be possible to slow or prevent vision loss from retinal degeneration.

Most ophthalmologists and optometrists are probably familiar with optical coherence tomography (OCT), the non-invasive imaging test that uses light waves to take cross-section images of a patient’s retina. However, OCT is being applied in new ways that might surprise even the eyecare professionals who use it in their everyday practice. Duke University recently announced that researchers there are now applying lessons learned from decades of perfecting the eye imaging technology to autonomous systems sensor technologies used in robots and vehicles.

Biomedical engineers at Duke University
have demonstrated a method for increasing the depth at which optical coherence tomography (OCT) can image structures beneath skin. The gold standard for imaging and diagnosing diseases within the retina, OCT has yet to find widespread use as an imaging technique for other parts of the body due to its inability to return clear images from more than a millimeter beneath the skin’s surface. Duke researchers found that tilting the light source and detector used in the technique increases OCT’s imaging depth by almost 50 percent, putting skin diagnoses within reach. The “dual-axis” approach opens new possibilities for OCT to be used in applications such as spotting skin cancer, assessing burn damage and healing progress, and guiding surgical procedures.

NEW YORK—If the term “smart glasses” still conjures up images of Google Glass for you, it’s time you took another look at them. Smart glasses have come a long way in the eight years since Glass’s brief but controversial run as a consumer product, which ended due to its unconventional styling, high price and privacy concerns related to its onboard video camera.

Calling the James Webb Space Telescope
an "eye in the sky" barely hints at its power, precision and vast capabilities. Launched by NASA in December, 2021 following years of research and development, and an investment of $10 billion, the Webb Telescope is by far the most sensitive and sophisticated instrument of its type ever developed, a pinnacle of scientific achievement. Its ambitious mission, to peer into space and provide clear images of distant planets, stars and whole galaxies that are light years away from Earth, is unprecedented in scope and complexity.

Starting with the launch of Google Glass in 2013, tech giants such as Google, Meta and Amazon have been exploring ways to make eyeglasses a vehicle for their consumer technologies. A prominent example is Ray-Ban Stories, which features a Ray-Ban frame with camera and audio capabilities and is the result of Meta’s collaboration with EssilorLuxottica.
