Scientists have discovered that the high pressure in the eye that occurs with most common forms of glaucoma can trigger two genes that work together to cause vision loss, a finding that may help pave the way for new glaucoma drugs.

There is currently no way to prevent onset or worsening of glaucoma and it is usually treated by managing fluid pressure inside the eye.

The researchers looked at the genes involved in primary open-angle glaucoma, the most common form of the disease, which usually affects people over 50 and can cause blindness.

Imagine yourself as a graphic designer for New Age musician Enya, tasked with creating her next album cover. Which two or three colors from the grid below do you think would “go best” with her music?

Would they be the same ones you’d pick for an album cover or music video for the heavy metal band Metallica?

Probably not.

The consistency of the whole appearance rather than the attractiveness of the parts is not just  saying, it's science, according to a study where participants were shown schematic point-light displays that depict a person using 15 moving dots.

The representation conveyed both the individual characteristics of a person's movements and their individual body shape. 

The team isolated these two areas and separately measured the attractiveness of individual movement styles as well as individual body shapes based on ratings obtained from his research participants. The researchers then combined the movement style of one person with the body shapes of another person and collected attractiveness ratings from these "hybrid walkers".

Researchers at the Medical and Surgical Center for Retina have developed software that detects eye diseases such as diabetic macular edema using a smartphone. 

The technology was designed for general physicians who support the health system in Mexico to detect certain abnormalities without  an ophthalmologist and send the patient to the specialist.

It's obviously better and cheaper to prevent blindness rather than try to cure it so an app on a cellphone that just needs to focus on the eye is better in all ways. This is especially important in rural communities, where expertise areas such as ophthalmology won't be commonly available.

I’m on the back seat of the lower deck of a number 37 bus, outside the red-brick and Portland stone clock tower of Lambeth Town Hall in Brixton, south London.  Although I know exactly where I am, I feel lost. I no longer know whether to trust what my eyes are telling me.

I’ve just been told by a leading vision scientist that I have no real depth perception. 

In other words, I have never seen in three dimensions the way most people do.

Lisa Marie Potter, Inside Science - Thank goodness for autostabilization, the digital camera feature that compensates for movement to achieve that crystal-clear, spontaneous selfie.

Myopia or short-sightedness is becoming more common across Europe, according to a new meta-analysis of findings from 15 studies by the European Eye Epidemiology Consortium which found that around a quarter of the European population is short-sighted but it is nearly twice as common in younger people, with almost half (47 per cent) of the group aged between 25 and 29 years affected.

Scientists have discovered that mutations in the gene DRAM2 cause a new type of late-onset inherited blindness. 

The article describes individuals from five families with a variety of DRAM2 mutations, all of which lead to loss of central vision beginning at age 30-40. Peripheral vision loss is also described in older individuals. The light-sensing rear surface of the eye (the retina) relays visual information to the brain. It's a complex layered structure, with each layer of cells carrying out clearly defined functions. 

A few months ago, a snapshot of a lace-decorated dress puzzled social networks worldwide. Some people saw a blue and black dress while others saw the same dress as white and gold

The reason behind the confusion, it is now known, is the photograph's overall bluish and yellowish coloring. A team of psychologists set out to experimentally test how it happened.
Most cameras have an auto-stabilization feature to compensate for movement during - and our eyes do also.

But in order for that imperceptible reflex that prevents our vision from blurring when we move to do its job, wirelike projections - axons - of specialized nerve cells must find their way from the retina to the correct part of the brain during embryonic development.

How those axons find their way through the brain's maze of neurons to make the right connection could lead to new ways to treat eye movement disorders.
