Recent years have seen major strides in basic science and clinical research on age-related macular degeneration (AMD)—the leading cause of vision loss in older adults. The August issue of Optometry and Vision Science, official journal of the American Academy of Optometry, is a theme issue devoted to advances and challenges in AMD research. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
Sunscreen and sunglasses top the list of summertime must-haves for most people. But just as skin can burn on an overcast or chilly day, eyes can sustain damage anytime you’re outdoors without sunglasses.
Researchers at the National Institutes of Health have developed a technique that will speed up the production of stem-cell derived tissues. The technique will help the researchers in their efforts to use patients’ skin cells to regenerate retinal pigment epithelium (RPE)—a tissue in the back of the eye that is affected in several blinding eye diseases. It will also help the scientists search for drugs for personalized treatments.
Researchers at the University of California, San Diego School of Medicine and Sun Yat-sen University in China have shown that acute glaucoma in mice is largely an inflammatory disease and that high pressure in the eye causes vision loss by setting in motion an inflammatory response similar to that evoked by bacterial infections.
In a new study led by UC San Francisco (UCSF) scientists, a chemical compound designed to precisely target part of a crucial cellular quality-control network provided significant protection, in rats and mice, against degenerative forms of blindness and diabetes.
Depression is a common risk for people who have lost their vision from age-related macular degeneration (AMD), but a new study shows that a type of rehabilitation therapy can cut this risk in half.
The first clinical trial to examine integrated low vision and mental health treatment has shown that the approach can reduce the incidence of depression by half among people with low vision due to age-related macular degeneration (AMD). The results of the study were published online today in Ophthalmology, the journal of the American Academy of Ophthalmology.
Researchers at the National Eye Institute (NEI) have described the functions of a gene responsible for anchoring cilia – sensory hair-like extensions present on almost every cell of the body. They show in a mouse model that without the gene Cc2d2a, cilia throughout the body failed to grow, and the mice died during the embryonic stage. The finding adds to an expanding body of knowledge about ciliopathies, a class of genetic disorders that result from defects in the structure or function of cilia.
Uveitis occurs when immune cells invade the eye, causing inflammation, swelling and vision loss. Researchers at the National Eye Institute (NEI) have found a unique type of immune cell and a secreted protein that, in tests on mice, can protect against the disease.
The American Academy of Ophthalmology – the world’s largest association of eye physicians and surgeons – is reminding the public that it does not recommend marijuana or other cannabis products for the treatment of glaucoma.
Trained non-physician evaluators who studied retinal images transmitted to a remote central reading center successfully identified newborn babies likely to require a specialized medical evaluation for retinopathy of prematurity (ROP).
Telemedicine is an effective strategy to screen for the potentially blinding disease known as retinopathy of prematurity (ROP), according to a study funded by the National Eye Institute (NEI). The investigators say that the approach, if adopted broadly, could help ease the strain on hospitals with limited access to ophthalmologists and lead to better care for infants in underserved areas of the country. NEI is a part of the National Institutes of Health.
A multi-center study has found that telemedicine is effective in screening for the potentially blinding disease retinopathy of prematurity in newborns.
German researchers have found strong evidence that attaining a higher level of education and spending more years in school are two factors associated with a greater prevalence and severity of nearsightedness, or myopia. Published online this month in Ophthalmology, the journal of the American Academy of Ophthalmology, the research is the first population-based study to demonstrate that environmental factors may outweigh genetics in the development of myopia.
New approaches and tools are needed to improve visual accessibility for people with low vision in the "real world,” according to a special article in the July issue of Optometry and Vision Science, official journal of the American Academy of Optometry.

The sensor would be embedded with an artificial lens during cataract surgery and would detect pressure changes instantaneously, then transmit the data wirelessly using radio frequency waves.
The University of California, San Diego School of Medicine is the first ophthalmology department in the nation to feature a fully dedicated high-fidelity, highly realistic driving simulator for evaluating the effects of visual impairment on a person’s driving performance.
Using a type of human stem cell, Johns Hopkins researchers say they have created a three-dimensional complement of human retinal tissue in the laboratory, which notably includes functioning photoreceptor cells capable of responding to light, the first step in the process of converting it into visual images.

Findings from a new study published in Translational Vision Science & Technology (TVST) show the brain, not the eye, controls the cellular process that leads to glaucoma. The results may help develop treatments for one of the world’s leading causes of irreversible blindness, as well as contribute to the development of future therapies for preserving brain function in other age-related disorders like Alzheimer’s.
In laboratory tests, researchers have used electrical stimulation of retinal cells to produce the same patterns of activity that occur when the retina sees a moving object. Although more work remains, this is a step toward restoring natural, high-fidelity vision to blind people.
A new study offers an explanation for how years of chronic sunlight exposure can increase the risk of cataract, a clouding of the eye lens that typically occurs with aging. The study firms up a link between the sun’s damaging rays and a process called oxidative stress.
If all eye doctors prescribed the less expensive of two drugs to treat two common eye diseases of older adults, taxpayer-funded Medicare plans could save $18 billion over a 10-year period, say researchers at the University of Michigan.
Projects to provide low-cost eyeglasses for people in the developing world and to develop a cell-death detector will share $25,000 in cash to further develop their projects as winners of the 2014 Discovery Competition. Washington University in St. Louis’ School of Engineering & Applied Science created the competition in 2012.

Blurred vision contributes to the risk of falling in older adults—but getting new glasses with a big change in vision prescription may increase the risk rather than decreasing it, according to a special article, ‘2013 Fry Lecture: Blurred Vision, Spectacle Corr & Falls in Older Adults’ in the June issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

The research is being presented at the 2014 Annual Meeting of the Association for Research in Vision and Ophthalmology (ARVO) this week in Orlando, Fla.
The eye is an exquisitely sensitive system with many aspects that remain somewhat of a mystery—both in the laboratory and in the clinic. A U.S.-based team of mathematicians and optometrists is working to change this by gaining a better understanding of the inner workings of tear film distribution over the eye’s surface. This, in turn, may lead to better treatments or a cure for the tear film disease known as “dry eye.”
