Some thought technology would make braille redundant – but the real threat is a lack of education and resources.
This is what it's like going to the cinema when you can’t see the screen.
A successful gene therapy for the leading cause of sight loss in children is being reviewed by the FDA.
Including different populations in genetic research studies can provide more varied results.
There is value in including different populations in genetic research studies as has been shown in a study on exfoliation syndrome, which leads to glaucoma.
Accurate diagnosis of glaucoma requires trained specialists and advanced equipment.
Glaucoma is a slow and silent progressive disease and the second leading cause of blindness, that requires early diagnosis.
The way someone with glaucoma sees.
Glaucoma is the sneak thief of sight, affecting the eyesight of more than 50 million people worldwide. It remains the biggest preventable cause of blindness today.
The pathway from eye to brain begins in the retina, where light is converted into neuronal signals.
Light arriving from the right visual field is processed in the brain's left hemisphere. So damage to the left part of the primary visual cortex will result in blindness in the right visual field.
Cataracts are one of the leading causes of visual impairment globally.

More than a million Australians have an untreated cataract and hundreds of cataract surgeries are performed daily, but what are they?
Trachoma disappeared from most of Australia 100 years ago as individual and community hygiene improved.
Trachoma easily spreads from one child to another through infected eye and nose secretions. A person may have up to 40 episodes of reinfection during childhood.
In some people AMD progresses so slowly that people do not notice the change in their vision.
Macular degeneration affects the part of the eye that allows you to see fine detail. Age-related macular degeneration is the main cause of blindness in Australia.
The next generation of neuroprosthetics could communicate directly with the brain to tackle diseases such as epilepsy and blindness.
Children with albinism often have poor eyesight, so classroom seating plans are important.
In Tanzania, where albinism is common, there's plenty that ordinary teachers can do to support students with albinism – much of it quite simple.
Cataract blindness continues to affects tens of millions of people because they cannot access proper care.
There aren't enough eye surgeons to perform all the cataract ops that are needed. Luckily, a solution might be at hand.

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, which may help pave the way for new glaucoma drugs.

We live in a visual world and build environments that rely heavily on visual perception. Want to find somewhere? You look on a map or read a road sign. Perhaps the GPS on your touch screen smartphone can…
Checking for glaucoma.
Scientists have proposed a way to monitor glaucoma using a tiny device implanted in the eye. Readings from the device could be monitored by a smartphone. The technology could help prevent some people from…

In sub-Saharan Africa and parts of Latin America, there is a parasitic worm that infects about 25m people, causing serious skin diseases, epilepsy and blindness. Known as Onchocerca volvulus, it can live…
