Rehabilitation Prevent Depression From AMD PDF

Ophthalmology and Optometry
Thursday, 31 July 2014

Depression is a common risk for people who have lost their vision from age-related macular degeneration (AMD), but a new study shows that a type of rehabilitation therapy can cut this risk in half.

As the AMD progresses, it can cause a growing blurred area near the center of vision, and lead to difficulty with everyday activities, including the ability to drive, read, write, watch television, cook, and do housework. Activities that used to be fun and fulfilling may begin to seem burdensome or even impossible. With loss of the ability to drive and navigate unfamiliar places, it becomes easier to stay at home than to see friends or meet new people. All of this can take a toll on mental health, and past studies have found that as many as one-third of people with bilateral AMD develop clinical depression.

In a trial researchers recruited 188 participants with bilateral AMD. Participants were 84 years of age on average, 70 percent were women, and 50 percent lived alone. All had a best-corrected vision of less than 20/70. Each participant had mild depressive symptoms and was at risk for developing clinical depression, based on a nine-item depression subtest of the Patient Health Questionnaire, or PHQ-9. During the trial, the participants had two visits with an optometrist, during which they were prescribed low-vision devices such as handheld magnifiers. After those initial visits, the participants were randomly split into two groups.

One group received behavior activation from an occupational therapist specially trained in the approach. The occupational therapist worked with participants to guide them on using the low-vision devices, to make changes around the home (such as using brighter lights and high-contrast tape), to increase their social activities, and to help them set personal goals and break these down into manageable steps.

The second group of participants served as a control group. They talked about their difficulties to a therapist, but did not receive behavior activation or low-vision occupational therapy. Both groups had six one-hour therapy sessions in their homes over a two-month period. All participants were allowed to take antidepressants, but less than 10 percent did so. All received medical management of AMD as prescribed by their primary eye care providers.

By four months, 12 participants in the control group and seven participants in the behavior activation group had withdrawn from the trial or passed away. Of the remaining 169 participants, 18 (23.4 percent) in the control group and 11 (12.6 percent) in the behavior activation group developed clinical depression, based on retesting with the PHQ-9. Behavior activation had the most benefit for participants with the worst vision (less than 20/100), reducing the risk of depression by about 60 percent compared to controls. When the data were adjusted for vision status, physical health and baseline PHQ-9 score, behavior activation reduced the risk of depression by 50 percent compared to the control treatment.

Innovative Display Technology Adapts To Optical Prescription PDF

Innovative Corrective DisplayResearchers at MIT, Microsoft, and University of California, Berkeley are developing technology that can adjust an image on a display so you can see it clearly without corrective lenses. The technology uses algorithms to alter an image based on a person's glasses prescription together with a light filter set in front of the display. The algorithm alters the light from each individual pixel so that, when fed through a tiny hole in the plastic filter, rays of light reach the retina in a way that re-creates a sharp image. Researchers say the idea is to anticipate how your eyes will naturally distort whatever's onscreen, something glasses or contacts typically correct, and adjust it beforehand so that what you see appears clear.

In addition to making it easier for people with simple vision problems to use all kinds of displays without glasses, the technique may help those with more serious vision problems caused by physical defects that can't be corrected with glasses or contacts, researchers say. This includes spherical aberration, which causes different parts of the lens to refract light differently.

While similar methods have been tried before, the new approach produces a sharper, higher-contrast image. The technology can be adjusted for different viewers, but it won't currently work for several people simultaneously who have different vision needs.

Luxottica Retail Australia Loses ADF Optometry Service Contract PDF

Monday, 28 July 2014

Medibank Health Solutions (MHS), the medical and allied health provider to Australian Defence Force (ADF) personnel, announced last Friday that it had terminated its contract with its optometry service provider, Luxottica Retail Australia Ltd, effective immediately. MHS advised Defence that Luxottica breached its contractual obligations by transferring optical claims information overseas for processing. MHS has apologised to all ADF personnel for any concerns that this breach has caused. In July 2012, eyesmart.com.au reported that Luxottica had secured the contract, valued at AUD 33.5 million, for optical services with the ADF as an exclusive subcontractor to prime contractor Medibank.

While the exact nature and amount of information transferred out of Australia is still being confirmed, it is assumed that all ADF personnel who received optical services through Luxottica since October 2012 are affected. Vice Chief of the Defence Force, Vice Admiral (VADM) Ray Griggs, has advised all ADF personnel of the issue and outlined interim arrangements for optical services.

"Both the Chief of the Defence Force, Air Chief Marshal Mark Binskin, and I are treating this issue very seriously," VADM Griggs said. "Our priority is to understand the extent of the data transferred overseas while ensuring ADF members can continue to access optical services."

VADM Griggs said Defence was working to fully assess the impact of Luxottica's actions for both individual ADF members and Defence. MHS has confirmed no other subcontractor providing services under the Defence contract is handling personal information off-shore.

OcclesOccles are the brainchild of couple, Hugh Robertson and Lynne McLeod. They first had the idea for Occles in 2011 whilst lying on a beach in Greece. Struggling to rest their eyes in the strong sunlight, they looked around and noticed various methods being employed by fellow holidaymakers to block out the sun's glare. The most common seemed to be a towel over the head! They knew at that moment, there had to be a better way.

Three years on, following extensive market research, and huge efforts to perfect the design and comfort of the product, Occles is really taking shape. Occles are patent (pending) with a registered design and a trademark for the brand. Occles are unique bridgeless eyeshades that wrap around the head and block out all ambient and uv light. The silicone rubber eye seals ensure a comfortable fit and the design helps prevent panda/raccoon eyes.

It is the company's mission to enable you to protect your eyes from the discomfort of UV and strong ambient light, and also reduce eye fatigue. Occles Ltd is a company registered in the UK. Occles is currently undertaking an Indiegogo crowdfunding campaign to raise funds.
