Researchers have found a source of stem cells behind the eye, which one day may be used to repair the damage from AMD and other diseases. Accessible by minor surgery, this stash of stem cells is much easier to obtain than previous finds.
A world first study into the connection between glaucoma and falls has found that those who suffered vision loss in their lower peripheral vision are thosemost likely to have a fall. According to Dr Alex Black, who lead the study, this finding can now be used to find ways to help prevent these patients from having falls.
The Ocular Nutrition Society has found many American Baby Boomers unaware of the benefits for eyesthat nutrition canbring. 60% did not know the benefits of Omega 3, and other essential nutrients for eye health. Almost 50% did not have annual eye tests, but 78% ranked vision as their most precious out of the five senses. Australians are likely to be the same, or even worse, according to some.
A study of identical twins has shown that eating a diet high in Vitamin D decreases the rate at which AMD progresses. It also showed that the more a person smoked, the more severe AMD became.
An algorithm has been established to predict advanced Age-Related Macular Degeneration. It looks at body mass index, smoking status, genetic variations, pre-existing retinal disease, among other things and found they strongly correlated with a higher chance of developing advanced AMD, a large study has shown.

Vitamin A has been found to aid in good eye health, and squash is filled with the nutrient. Now in season, squash provides many more benefits, such as fibre and Vitamin C.
A study has disproven that caffeine is behind the increase in intraocular pressure in patients with open angle glaucoma. However, the study has shown that other ingredients in coffee, and osmotic effects caused by intake of fluids, may be behind the increase.
Biologists have made tadpoles grow eyes on their backs with genetic manipulation.The new mechanism has many uses for translation and regenerativemedicine applications.
A new technology has allowed optometrists to consider implanting a sort of robot in a Diabetic Retinpathy sufferer. The primary purpose would be for it to release a dosage of docetaxel into the back of the eye. With no batteries and powered by a magnetic field, it can last for more than 35 days without any leakage or problems. Testing is still underway.
European Eye Study researchers suspect that frequent aspirin use can make Age-related Macular degeneration more likely. According to an analysis of 4691 subjects 65 years or older, participants who used aspirin daily had an increased occurrence of AMD. However, the study was not conclusive as it was unknown the dosage of each aspirin taken, and the possibility that subjects may have started taking aspirin after experiencing visual problems.

Adelaide based Calpain Therapeutics has won the annual Enterprize business plan contest run by Queensland Business School. Their pitch was to develop a drug to delay cataract growth by targeting a particular protein in the eye's tissue thought to cause clouding of the eye's lens. The company is very grateful for the money which will be used to fund human lens experiments, vital in understanding more about cataracts.

It is our policy each patient is to be examined by the optometrist according to individual need, i.e., the examination to be as comprehensive or brief as is called for based on the presenting problem. The optometrist based on the nature of the patient’s condition also determines follow-up visits for various conditions. The following general guidelines, by diagnosis, may appropriately be applied when deciding how often to see a patient for a particular clinical problem.
1. GLAUCOMA -- 3-4 months (lOP, direct ophthalmoscopy, and visual field test)2. CATARACTS -- 6-12 months (requires slit lamp exam & IOP)3. APHAKIA -- once a year4. PSEUDOAPHAKIA with capsular haze -- 6 months-once a year5. MACULAR DEGENERATION -- 4-6 months, except for end stage6. RETINOPATHY-- Diabetic, background -- 3-6 months-- Diabetic, proliferative -- 3 months-- Hypertensive -- 6 months, variable if severe-- Arterial or Venous Occlusion -- 3 months-- At macula -- 3 months7. DRY EYE SYNDROME -- Determined by severity & complications.8. ACUTE PROBLEMS (conjunctivitis, iritis, blepharitis, episcleritis, chalazion, trichiasis, hordeolum, etc.) -- variable and as needed9. NUMEROUS OTHER RETINAL/OCULAR PATHOLOGY – as needed according to standards of care
These guidelines are general in nature and do not address any specific patient condition/situation. The judgment and actions of the treating optometrist are held to be expert and appropriate so long as they are justified by complete documentation on the patient clinical record. Optometrists recommend certain procedures to remedy the eye problems, or refer the patient out for surgical evaluation or consult from other specialists such as ophthalmologists and patient’general practitioner, etc. It is the facility staff’s responsibility to carry through with optometrists’ recommendation for proper care of the patient.
Retina imaging can aid in the early detection of Alzheimer's disease, a study from Australia has shown. The researchers found that the width of the retinal blood cells was significantly different between people with Alzheimer's and people without. This correlated with the build up of amyloid plaques in the brain, an indicator of Alzheimer's. The researcher hope that in the future a simple eye test can check for Alzheimer's without much hassle as before. More about this at: http://www.revoptom.com/content/c/29664/
A study in the US has concluded that people with diabetes are 35 percent more likely to develop open angled Glaucoma. The research team focused on metabolic syndromes to see how they would affect the likelihood of developing Glaucoma. The study also found however, that people with Hyperlipidemia were 5 percent less likely to suffer from Glaucoma in their lifetime.

Assist vision impaired elderly with low vision aids for their indepedent living
Researchers at Australian National University have concluded that the older a driver gets the more likely they will have driving problems. They tested 266 adults aged between 70 to 88 by riding with them while they drove and they came to the conclusion that as humans get older their ability to switch between tasks decreases, so they fail to check their blind spot, or do other smallthings that are essential for driving.

Ford is working with the Florida Government to design cars that are safer and easier for older drivers to use. They created a "third-age" suit which helped them feel what it is like for elderly people to drive cars. Some improvement ideas include bolder fonts for easier reading, warning signsto notify the driver that there is a car in their blindspot, and inflatable seat belts.

The new Shamir Golf lenses are what every golfer needs. Recently created to help with avid golfers, they help with short, medium, and long areas of focus so you can keep concentrated on your game, without having to struggle with the blur. They are available now from Mobile Eye Clinic.
A recent biological study has revealed that a similar pathway that links to the development of Parkinson’s disease also links to the development of glaucoma, the common cause of vision loss. The study found that gamma synuclein, a certain abnormal protein found in the optic nerve head is similar to the abnormal protein of alpha synuclein, which is a causes cell loss due to Parkinson’s disease. This study concludes that glaucoma and Parkinson’s disease have a similar biological process. This discovery may be the next step in finding a treatment for glaucoma, researchers say.
A recent study shows suggests that serum 25-hydroxyvitamin D has an effect against women getting aged-related macular degeneration (AMD). Vitamin D has anti-inflammatory, immune-modulating properties, which prevents the inflammation during the early stages of AMD. Further study is being done on the subject.

AMD (age-related macular degeneration) cases have dropped by more than 30% in the last 15 years, according to a study in the US. One significant reason may be related to the decline in smoking over the years, which is a leading cause of eye disease. Recent changes in diet, physical activity, and blood pressure may also have had an effect on the decline of AMD cases. AMD still remains one of the leading causes of vision loss.
A recent study suggests that dry eye symptoms improved after being treated with an omega-3 fatty acid dietary supplement. After experimentation and assessment of the effects, the study revealed that the patients who received the daily omega-3 supplement showed an increase in tear production and volume. 70% of the patients involved said that the symptoms were gone, while the other 30% said their symptoms improved.
The macula is the central part of the retina, at the back of the eye, that allows you to read, recognise faces, watch television, and drive a car. Macular degeneration (MD) happens when this part of the eye breaks down. MD affects one in seven people over the age of 50, and one in three over the age of 75. Early detection of MD is crucial, as lost vision cannot be regained.
Symptoms of MD include difficulty reading, seeing straight lines as bent, poor central vision, poor night vision, and intolerance of glare. Although there is no cure for MD, there are treatment options that can slow down its progression. The earlier the disease is detected, the more vision you are likely to retain, so please ensure you have your eyes examined regularly, even before symptoms appear.

A Sydney study has found that moderate consumption of alcohol may be associated with a reduced need for cataract surgery. The long-term study found that subjects who drank two or more alcoholic drinks a day, as well as those who did not drink at all, showed a higher incidence of cataract surgery than those who drank one or two alcoholic drinks a day (mivision iss. 52).
A recent study, involving eye-tests of over 2,000 Australians, has helped to identify people at high risk of developing glaucoma. Thanks to the research conducted by deCODE genetics Inc, Iceland and Dr. Jamie Craig from Flinders University, South Australia, scientists have been able to identify genes contributing to risk for glaucoma. The findings represent an important step toward a better understanding of glaucoma and will likely lead to better diagnostic and predictive tests, as well as new treatments (mivision iss. 52).
Optometrists conduct eye and vision examinations, prescribe spectacles and contact lenses, and carry out treatment for eye disorders, diseases and injuries. They also give out visual appliances, such as glasses and contact lenses. For most eye problems, you would see an optometrist.
Ophthalmologists specialize in the treatment of eye diseases and surgery. For serious eye problems, an optometrist may refer you to an ophthalmologist who is qualified to perform major eye surgery and prescribe advanced treatment for serious eye diseases.
Poor vision can result in falls, one of the main reasons for admissions into hospital for over-75s. Here are a few ways you can protect yourself from falls:
Since sight is arguably our most important sense, it is no surprise that many people experience low moods when faced with vision loss. When these low moods become intense and persist for long periods of time, this may signify clinical depression. In fact, an estimated one third of older visually impaired adults show clinically significant depressive symptoms.
To address this issue, the National Health and Medical Research Council (NHMRC) has awarded the Centre for Eye Research Australia (CERA) with a grant to train eye practitioners in how to manage depression. The hope is that eye practitioners can eliminate unnecessary depression by linking patients with much-needed treatment.
Transition Optical was the first company to successfully commercialise a plastic photochromic lens (a type of transition lens) in 1990 and is now a world leader in photochromic lenses.

Most people know that ultraviolet (UV) rays damage skin. In fact, UV rays are even more damaging to eyes. Accumulated UV exposure can lead to cataracts, macular degeneration and pterygium (a fleshy growth on the cornea).
The best way of protecting your eyes is by wearing appropriate sunglasses and limiting your exposure between 10am and 4pm when the sun’s effects are the strongest. Although some contact lenses provide some UV protection, best is to wear wrap-around sunglasses that screen more than 95 percent of both UVA and UVB light, or those labeled as Category 2, 3, or 4. Also, be sure to have your eyes checked regularly; the earlier UV-related conditions are detected, the better the chance of treatment.
The Australian senate passed a motion in November 2009 to disallow Medicare rebates for cataract surgery items. No longer can patients receive rebates for having cataract surgery.
