Discovery of a new protein has been linked to vision loss

Glaucoma affects more than 60 million people throughout the world, and what with increasing longevity and ageing populations this number is set to increase.    However a new study documented in the Proceedings of the National Academy of Sciences has identified a build up of protein called gamma synuclein in a new biological pathway at a specific site in the optic nerve of mice.    Research shows patients with Parkinson’s disease appear to have a similar protein present, which is thought to be a result of neuronal breakdown.     These findings are a major step forward in the quest to discover a treatment that will cure glaucoma and remove the threat of blindness that hangs over so many millions of people.

Glaucoma – Don’t turn a blind eye to the disease!

Glaucoma is categorised as a disorder that affects the function of the eye. The characteristics of Glaucoma produce specific signs and symptoms, and ultimately share a single common feature, progressive optic neuropathy (Damage to the optic nerve).  All manifestations of Glaucoma can result in progressive loss of vision if untreated, or undetected, eventually this can be potentially blinding.

Incorporating the Glaucoma’s as a group of diseases, they are now the leading source of visual morbidity, affecting more than 60 million people throughout the world.  What’s more, around 8.4 million...   read more

Children’s Vision Neglected

Many parents will be familiar with the importance of immunisations, routine screenings such as hearing tests, weight, and growth charts for their new born not to mention dental health when the time arises, but what about their vision?

The Eye Care Trust has warned that one in five children before the age of 12 has an undiagnosed visual problem, which could interfere with their ability to learn.

It is recommended for children eight years or younger to have an annual eye examination. Children aged nine and upwards, generally would have an eye examination every two years unless your optician has...   read more

Eye Test may detect Alzheimer’s disease before symptoms develop.

Research currently underway by scientists from the University College London believe Alzheimer’s and other diseases could be detected by a simple and inexpensive eye test that could be available from high street practices within the next five years.

The non-invasive method uses fluorescent markers, which enable early indication of brain cell death by attaching to dying cells on the retina. The dying cells absorb the fluorescent dye which show up as green dots. (Image Below)

These experiments are currently being tested on mice, but the first human trials could begin this year. This fundamental...   read more

Eye Health Awareness Week 2010 – Day 7: Stress & Eye Strain

Eye strain is now a hazard of daily life with our ever-increasing use of screens. Strain occurs simply from focusing on one distance for too long and can be easily mitigated by taking regular screen breaks. Other contributing factors to eye strain are poor lighting, having your computer at the wrong height, a stuffy atmosphere and – of course – stress.

Just because we all use computers these days it doesn’t mean that our eyes are no longer susceptible to strain so just as much care needs to be taken to rest the eyes as it did when computers were first introduced to the workplace. Screen...   read more

Eye Health Awareness Week 2010 – Day 6: Ultraviolet Radiation

How exposed are you to Ultraviolet radiation?

We all enjoy a good measure of sunlight to make us feel good, perhaps it’s a trip to the beach or the local pack with the kids to ensure our vitamin D levels are topped up thanks to exposure from natural sunlight.  All the same, we are more familiar, now more than ever of the damaging effects the sun has to our skin as a result of excessive UV radiation with 85% of the British public knowing about the risk of skin melanoma.

Regrettably our awareness from exposure of the suns harmful UV rays stops here with a staggering 90% of the British public completely ignorant of the need to protect their...   read more
