March is Workplace Eye Wellness Month

March is Workplace Eye Wellness Month. Along with many other eye care providers across the nation, as well as the American Academy of Ophthalmology, PCVI in Eugene is promoting good eye health in the work place. Safety Eyewear: A Critical Component One of the most obvious and effective ways to reduce workplace eye injuries is… Read More


February is Age-related Macular Degeneration Awareness Month

Age-related Macular Degeneration (AMD) is the leading cause of blindness among older Americans, but new treatments have dramatically changed the course of this disease over the last 10 years, making AMD more manageable than ever before. During AMD Awareness Month in February, the American Academy of Ophthalmology is reminding people with AMD that they can… Read More


Researchers discover way to improve image sharpness for blind people with retinal implants

Retinal implants that deliver longer pulses of electrical current may noticeably improve image sharpness for individuals who have lost their sight due to retinitis pigmentosa, according to a new study by researchers from the USC Eye Institute and USC Viterbi School of Engineering. The research will be published in the peer-reviewed journal Science Translational Medicine… Read More


Retinal cells work with little reserve energy; may explain vulnerability to eye diseases

Our eyes are especially demanding when it comes to energy: Along with our brain, they require a substantial amount of power to keep them functioning and healthy. Now a new study by the National Eye Institute suggests that because of their high-energy demands, our eyes function at high efficiency and with little reserve capacity, which… Read More


Damage in retinal periphery closely matches loss of blood flow in people with diabetes

Research from the Joslin Diabetes Center’s Beetham Eye Institute demonstrated earlier this year that in people with diabetic retinopathy, the presence of lesions in the periphery of their retina substantially increases the risk that the disease will progress more rapidly. A follow-up study has shown that these peripheral lesions, which are not detected by traditional… Read More


Retinal nerve cells grown in the lab – Work could eventually lead to cell transplants for people blinded by glaucoma

Johns Hopkins researchers have developed a method to efficiently turn human stem cells into retinal ganglion cells, the type of nerve cells located within the retina that transmit visual signals from the eye to the brain. Death and dysfunction of these cells cause vision loss in conditions like glaucoma and multiple sclerosis. “Our work could… Read More


How the retina marches to the beat of its own drum

Researchers at Johns Hopkins and the University of Washington report new research that sheds light on how the retina sets its own biological rhythm using a novel light-sensitive pigment, called neuropsin, found in nerve cells at the back of the eye. “No one knew what neuropsin actually did,” says King-Wai Yau, Ph.D., a professor of… Read More


January is Glaucoma Awareness Month!

Glaucoma is a leading cause of irreversible blindness in the United States. Glaucoma has no noticeable symptoms in its early stages, and vision loss progresses at such a gradual rate that people affected by the condition are often unaware of it until their sight has already been compromised. During Glaucoma Awareness Month in January, the… Read More


Retina protein that may help conquer blindness discovered

Research led by Nicolas Bazan, MD, PhD, Boyd Professor and Director of the LSU Health New Orleans Neuroscience Center of Excellence, discovered a protein in the retina that is crucial for vision. The paper reports, for the first time, the key molecular mechanisms leading to visual degeneration and blindness. The research reveals events that may… Read More


Receptor that helps protect brain cells has important role in support cells for the retina

A receptor that is already a target for treating neurodegenerative disease also appears to play a key role in supporting the retina, scientists report. Without sigma 1 receptor, the Müller cells that support the retina can’t seem to control their own levels of destructive oxidative stress, and consequently can’t properly support the millions of specialized… Read More
