Discovery Of New Functions Of Brain Regions That Are Responsible For Seeing Movement
When observing a fly buzzing around the room, we should have the impression that it is not the fly, but rather the space that lies behind it that is moving. After all, the fly is always fixed in our central point of view…
Glaucoma Prevented By Targeted X-Ray Treatment In Mice
Jackson Laboratory researchers have demonstrated that a single, targeted x-ray treatment of an individual eye in young, glaucoma-prone mice provided that eye with apparently life-long and typically complete protection from glaucoma. In research publish…
News From The Journal Of Clinical Investigation: March 19, 2012
A clearer understanding of glaucoma Glaucoma is one of the leading causes of vision loss and blindness worldwide. In glaucoma patients, the optic nerve, which relays information from the eye to the brain, is damaged, though the molecular cause of nerv…
Blood Vessel Disease Of Retina May Be Marker Of Cognitive Decline
Women 65 or older who have even mild retinopathy, a disease of blood vessels in the retina, are more likely to have cognitive decline and related vascular changes in the brain, according to a multi-institutional study led by scientists at the Universit…
Eye Disease As Marker Of Brain Health
A new US study suggests that screening for retinopathy, a disease of blood vessels in the retina at the back of the eye, could serve as a marker for brain health, after researchers found that women aged 65 and over with even a mild form of the diseas…
Brain And Eye Abnormalities In Astronauts Caused By Prolonged Space Travel
Magnetic resonance imaging (MRI) of the eyes and brains of 27 astronauts who have spent prolonged periods of time in space revealed optical abnormalities similar to those that can occur in intracranial hypertension of unknown cause, a potentially serio…
Glaucoma Screening Program Likely Benefit Middle Aged African-Americans
According to a computer-based mathematical model in the March issue of the JAMA journal Archives of Ophthalmology, middle-aged African-American patients may benefit from a routine national glaucoma screening program. However, the test’s potential effec…
Hope Of Treatment For Debilitating Eye Disease Using New Pig Model
A newly developed, genetically modified pig may hold the keys to the development of improved treatments and possibly even a cure for retinitis pigmentosa (RP), the most common inherited retinal disease in the United States…
Diagnosing Eye Disorder Using Nintendo Wii Game Controllers
Wii remotes are not all about fun and games. Scientists can use them to assess and diagnose children with an abnormal head position caused by eye diseases. As described in a recent Investigative Ophthalmology & Visual Science article, researchers devel…
Managing Glaucoma – Home Measurements Of Eye Pressure In Children Effective
Large changes in intraocular pressure (IOP), also known as the pressure within the eye, in patients with glaucoma, tends to be associated with a progression of the disease that can result in permanent damage to a person’s optic nerve and their vision…
How A Bacterial Pathogen Breaks Down Barriers To Enter And Infect Cells
Scientists from the Schepens Eye Research Institute, a subsidiary of Mass. Eye and Ear and affiliate of Harvard Medical School, have found for the first time that a bacterial pathogen can literally mow down protective molecules, known as mucins, on muc…
Glaucoma Management In Children May Be Improved By Home Measurement Of Eye Pressure
Measurement of pressure within the eye, or intraocular pressure (IOP), is known to fluctuate throughout the day, and wide swings in patients with glaucoma are believed to be related to the progression of the disease, which can cause permanent damage to…
Glaucoma Characterized In New Research As A Neurologic Disorder Rather Than Eye Disease
A new paradigm to explain glaucoma is rapidly emerging, and it is generating brain-based treatment advances that may ultimately vanquish the disease known as the “sneak thief of sight.” A review now available in Ophthalmology, the journal of the Americ…
App Turns Tablet Into Math Aid For Visually Impaired Students
Without looking down, Kira runs her index finger across the screen of an Android tablet that she is holding in her lap. For the occasion, she has painted her fingernails bright pink. When her finger touches a line drawn on the screen, the tablet vibrat…

Using Stem Cells To Repair A Damaged Cornea
A new cornea may be the only way to prevent a patient going blind – but there is a shortage of donated corneas and the queue for transplantation is long. Scientists at the Sahlgrenska Academy at the University of Gothenburg, Sweden, have for the first …

Hungry People See Food-Related Words More Clearly
Our senses aren’t just delivering a strict view of what’s going on in the world; they’re affected by what’s going on in our heads. A new study finds that hungry people see food-related words more clearly than people who’ve just eaten…
Optogenetic Tool Elucidated
RUB researchers explain channelrhodopsin Controlling nerve cells with the aid of light: this is made possible by optogenetics. It enables, for example, the investigation of neurobiological processes with unprecedented spatial and temporal precision….
