World Sight Day 2014Nearly half a million Australians are blind or vision impaired. Amazingly, only three per cent access services that could make a significant difference to their health and livelihoods. Without low vision services, activities sighted people take for granted, such as shopping, gardening, preparing meals, crossing the road and catching public transport can be difficult and dangerous. Low vision services promote independence, are available throughout Australia, and are usually provided free of charge.

Many people with low vision don't know the benefits of accessing services that can equip them with the skills they need to maintain their independence throughout life and in a variety of settings including: home, work, school and sport.

2014 is the first year of the WHO GAP (Global Action Plan) and IAPB (International Agency for the Prevention of Blindness) encourages its members and partners to continue with its rolling theme: Universal Eye Health. This year, the 'Call to Action' for World Sight Day is: "No more Avoidable Blindness". The Call to Action will draw attention to a few key interventions that are crucial for the success of GAP's target – reducing avoidable blindness by 25%, by 2019. Using the call to action as a clarion call, organisations can identify various aspects of GAP that need urgent attention. They are also invited to customise the call to action, to their disease area – "No more Cataract" or "No more Trachoma" for example.

 
Erectile Dysfunction Drugs Could Damage Vision PDF

ViagraAustralian researchers from the University of New South Wales (UNSW) have found that erectile dysfunction drugs could damage vision. Sildenafil, the active ingredient in the erectile dysfunction drug Viagra®, could cause unusual visual responses in people who carry a common mutation for eye disease and may have long-term detrimental effects on their vision, UNSW researchers warn.

Sildenafil can inhibit an enzyme which is important for transmitting light signals from the retina to the brain, and it is already known from clinical trials of Viagra® that its use in high doses can cause transient disturbances in the vision of some healthy people.

"Side effects can include sensitivity to bright light, blurred vision and altered colour vision," says Dr Lisa Nivison-Smith, of the UNSW School of Optometry and Vision Science.

"We are concerned that people who have normal vision but who carry a single copy of the mutant gene for the blinding disease, Retinitis Pigmentosa, could be more susceptible to these changes."

A team led by Dr Nivison-Smith and UNSW's Professor Michael Kalloniatis studied the effects of a single dose of sildenafil on normal mice and mice with a single copy of the mutant gene.

The results are published in the journal Experimental Eye Research.

They found the normal mice had a transient loss of visual function after sildenafil treatment, but this effect was heightened in the mice with the mutation, and the response lasted longer. They also found early signs of cell death in the eyes of carrier mice, but not in the normal mice, suggesting sildenafil may cause degeneration in carriers of retinal disease.

"These finding are highly significant because about one in 50 people are likely to be carriers of recessive genes which cause retinal disease but are unlikely to know this, because their vision is normal," says first author of the study, Dr Nivison-Smith.

The researchers are conducting further studies to work out the mechanisms behind long term effects of sildenafil on the eyes of carrier mice.

"A better understanding of the effect of this family of erectile dysfunction drugs could help scientists and clinicians plan more successful strategies to account for factors such as a patient’s medication and genetic makeup in diseases which cause blindness," says Dr Nivison-Smith.

Retinitis Pigmentosa is the most common genetic disease which leads to blindness. It can be caused by a mutation in the gene that produces the enzyme PDE6. People with two copies of the mutant PDE6 gene get the disease, while carriers, with just one copy, have normal vision.

Sildenafil is part of a family of drugs which inhibit the enzyme PDE5, to treat erections, but they can also inhibit PDE6. This is likely to be a problem for carriers of a mutant PDE6 gene, because they produce less of the enzyme than normal. To study the eyes of the mice, the team used a technique called electroretinography, which measures the electrical signals of cells in the eye when they are activated by light.

 
Researchers Find No Link Between Swimming Goggles and Glaucoma PDF

Lions Eye Institute (LEI) medical researchers have found no link between the regular use of swimming goggles and glaucoma. Reporting in the British Medical Journal, LEI Managing Director Professor David Mackey said previous studies had found a small but significant transient increase in intraocular pressure (IOP) – a risk factor in the development of glaucoma - in people wearing certain types of swimming goggles.

The studies found this increase was maintained while the goggles were on but returned to normal levels as soon as they were taken off.

"These past findings suggested that wearing goggles could represent a significant risk factor for developing or worsening of glaucoma in people who swim regularly," Professor Mackey said. "We performed comprehensive eye exams on 231 members of local swimming clubs and 118 non-swimmers. "Their IOP and retinal nerve fibre layer thickness were measured, with the result that we did not detect any new cases of glaucoma in our cohort of frequent swimmers. We also found no difference in the thickness of the retinal nerve fibre layers between swimmers and non-swimmers."

The research team concluded that frequent use of swimming goggles did not lead to an increased risk of glaucoma over time in adults.
