"Neovascular age-related macular degeneration (nvAMD) is a chronic, progressive disease of the central retina, and its prevalence is expected to rise with the aging population. Using a bottom-up approach based on retrospective data, this cross-sectional study estimated average annual direct costs of nvAMD to be A 4,047 pound, and average annual indirect costs to be A 449 pound," scientists in Bristol, the United Kingdom report.
"An attempt to measure intangible costs through willingness-to-pay yielded a lower response rate and estimated intangible costs to be 11.5% of monthly income. Direct costs were significantly higher for male participants, for those who have mild or moderate visual impairment in both eyes, and for those who have been diagnosed for a shorter time," wrote K.M. Ke and colleagues, University of Bristol.
The researchers concluded: "The findings of this study suggest that the availability of early diagnosis, effective treatment, support services, and sustained research into the management of nvAMD may reduce the burden of visual impairment caused by nvAMD to affected individuals and the state."
Ke and colleagues published their study in European Journal of Health Economics (The direct, indirect and intangible costs of visual impairment caused by neovascular age-related macular degeneration. European Journal of Health Economics, 2010;11(6):525-531).

Genetic Testing for AMD is here Today
by:Diana Shechtman OD FAAO & Steven Ferrucci OD FAAO
Age-Related macular degeneration (AMD) is a progressive disease and the leading cause of vision loss among the elderly, affecting central vision required for daily activities such as driving and reading. There are a number of factors affecting AMD, such as advanced age, smoking, UV exposure, overall health (that contribute to high blood pressure, obesity, diet) and family history. Many factors may be modified and yet others like genetics cannot. Although AMD may seem to be hereditary in some families and not others, genetics have been shown to contribute significantly to the disease. Multiple twin and sibling studies have collaborated to the familial nature of the disease. First-degree relatives of patients with AMD are at a significantly increased risk for the disease. Furthermore, large epidemiological studies have suggested a strong genetic risk factor for AMD. In fact, the risk of developing AMD increases 4 fold among patients with a positive family history. In 2005 a breakthrough occurred in the area of genetic research and AMD; Klein and associates discovered a strong link between AMD and certain genetic variants. Similarly, numerous other genes have been implicated in AMD, which may increase the risk of AMD up to 70%.
Until recently there was no test to help determined patient’s inherited risk for AMD. Today, Macula Risk (ArcticDX, Toronto, Ontario) is a genetic test specifically designed to determine genetic predisposition to AMD and vision loss attributed to the more advanced stage of the disease.
Macula Risk genetic test separates individuals into one of 5 macula risk (MR) categories, with MR 3 through 5 representing an increased risk for the more advance stage of the disease. This accounts for approximately 20% of the general population. MR1 has less than a 5% risk of the advanced stage of the disease, while MR 5 carries greater than 55% risk. These results can aid the doctor in devising a specific management plan and follow-up protocol in order to reassure early intervention to prevent vision loss.
The test only requires a simple in-office cheek swab, which is sent directly to the genetic lab. The report includes test results and written genetic support information (including access to genetic counseling). Macula Risk genetic testing is covered by most insurance providers, including Medicare, as long as the specific diagnosis (ICD-9) are identified by the doctor. The prognostic genetic test is intended for patients who have a diagnosis of early or intermediate AMD. Thus, the “at risk patient,” would have to pay a fee for the test.
Despite our best efforts and new treatment options available today, many people are still losing vision from AMD. New advancements in the area of AMD are becoming an integral part in preventing future visual deterioration. AMD is affected by both environmental and genetic factors that interact with one another to determine prevalence and progression of the disease. Furthermore, at this time we do not know all of the genes linked to AMD. Hence, genetic testing in the area of AMD is only a risk indicator and cannot predict “without a shadow of a doubt,” which patients will and which will not develop the disease. However, this test provides a genetic profile screening to help identify those at risk as well as aids in tailoring a distinct management approach for those with the disease. With various researches devoted to treatment options for AMD, genetic testing in the area of AMD is at the frontier of providing crucial information.

The link Between Age-Related Macular Degeneration and Cardiovascular Disease
by:Johns Hopkins Health Alert
Several studies have found that people with age-related macular degeneration (AMD) are more likely to have heart disease than those without age-related macular degeneration. A U.S. Medicare study, for example, found that elderly people with age-related macular degeneration were 20% more likely to have a heart attack than their counterparts who didn't have age-related macular degeneration. And a large Australian study, reported in the British Journal of Ophthalmology, suggests that age-related macular degeneration increases the risk of dying from coronary heart disease or stroke.
The researchers used data from nearly 3,000 participants, age 49 and older, in the Blue Mountains Eye Study -- none with a history of coronary heart disease or stroke at enrollment. They found that people younger than age 75 who had early signs of age-related macular degeneration at the study's start were twice as likely to die of coronary heart disease as their counterparts who did not have early signs. However, there was no increased risk of dying of a stroke in this group.
People with late age-related macular degeneration at the beginning of the study who were under age 75 had five times the risk of dying of coronary heart disease and 10 times the risk of dying of a stroke. The link between late age-related macular degeneration and risk of death from cardiovascular disease should be interpreted cautiously, warn the researchers, because there were so few people with late age-related macular degeneration at study entry.
Surprisingly, the researchers found no increased risk of death from cardiovascular disease among people over age 75 with age-related macular degeneration. They speculate that past 75, patients died of other serious health conditions that overshadowed the connection.
Take-away message: What's behind the link between age-related macular degeneration and cardiovascular disease? Some researchers suspect that age-related macular degeneration and cardiovascular diseases may share a common genesis: for instance, atherosclerosis, inflammation, and oxidative stress (the cell damage caused by free radicals) are known to affect both conditions. Another alternative: age-related macular degeneration may simply be a disease of aging.

DeGette Hails Approval of Second Embryonic Stem Cell Human Trial
by:PoliticalNews
Congresswoman Diana DeGette (CO-01) hailed the approval of the second human treatment trial using human embryonic stem cells. The test, just approved by the FDA, will be conducted by Advanced Cell Technology (ACT) and will focus on Stagart disease. Medical professionals believe a successful human trial will open the doors to the treatment of other, more common eye diseases such as macular degeneration. DeGette has been the leading Congressional advocate for federal funding of ethical embryonic stem cell research, as these investments drive breakthrough trials like the one announced this week.
“Embryonic stem cell research holds enormous promise for countless diseases,” said DeGette, “and the approval of this test is yet another step towards the breakthroughs it can bring for millions of Americans. I am excited to see the results of this, and other trials, and encourage my colleagues to recognize the enormous benefits of ethical embryonic stem cell research.”
Stagart’s disease affects central vision – e.g., reading and facial recognition – and can cause its victims to lose peripheral vision, only be able to see various levels of light, or ultimately go blind. This test will treat Stagart’s patients with healthy cells, created from embryonic stem cells, to replace the “scavenger cells” that deteriorate their vision.
The test is the second trial using embryonic stem cells to be approved in the United States. Last month, the Geron Corporation was permitted to conduct a trial involving embryonic stem cells to treat spinal cord injuries. Preliminary testing is still ongoing in that trial. Like the Geron trial, this latest trial will focus primarily on the safety and viability of embryonic stem cell use in the treatment of this condition. The Stagart’s trial will likely start early next year and 12 subjects will be treated.
“The approval of these two tests in such close order demonstrates how the investment by the federal government in ethical stem cell research is beginning to bear fruit for the millions of Americans facing debilitating diseases and conditions,” said DeGette. “The breakthroughs of these discoveries underscore the critical importance of finally codifying ethical stem cell research regulations, so our scientists and their critical work can no longer be subject to political whims.”

UC Santa Barbara Part of International Research Collaboration Focusing on Age-Related Macular degeneration Cure
By AScribe Newswire
SANTA BARBARA, Calif., Nov. 15 - An international collaboration between UC Santa Barbara, the Keck School of Medicine of the University of Southern California (USC), and several other research institutions, is bringing together leaders in the fields of stem cell biology, basic science, and ophthalmology to develop a treatment for blindness caused by age-related macular degeneration.
The California Project to Cure Blindness (CPCB) was formed with a $16 million California Institute for Regenerative Medicine (CIRM) "disease team" grant awarded in late 2009 to fund development of a stem cell-based treatment for age-related macular degeneration. As part of the CIRM Disease Team partnership program, an additional $4.1 million from Britain's Medical Research Council funds collaborative work at University College of London.
"UCSB scientists in the Center for Stem Cell Biology and Engineering and the Center for the Study of Macular Degeneration are excited to provide the basic research that will allow translation of stem cell research to the clinic," said Dennis Clegg, professor in UCSB's Department of Molecular, Cellular, and Developmental Biology, and co-director of the UCSB Center for Stem Cell Biology and Engineering. Both centers are part of UCSB's Neuroscience Research Institute. Grant funds totaling $2.5 million for this work were assigned to UCSB through USC.
The overall grant was awarded to principal investigator Mark Humayun, professor of ophthalmology, cell and neurobiology and biomedical engineering at the Keck School, and David R. Hinton, professor of pathology and ophthalmology at the Keck School. Co-investigator is Martin Pera, director of the Eli and Edythe Broad CIRM Center for Regenerative Medicine and Stem Cell Research at USC.
"With this collaboration, we hope to accelerate research on a stem cell-based therapy for age-related macular degeneration," said Humayun. "Age-related macular degeneration is the leading cause of irreversible vision loss, affecting one in three people age 75 or older. The CIRM grant enables us to work with numerous researchers and experts who are dedicated to finding the cure to this devastating medical condition."
The cause of blindness in age-related macular degeneration is the death of retinal pigment epithelial cells, which provide critical support of photoreceptor function and health. The project objective is to replace damaged retinal epithelium with healthy tissue derived from human embryonic stem cells to prevent loss of vision.
Stem cell therapy offers the possibility of a wider range of options for age-related macular degeneration patients, said Keck School Dean Carmen A. Puliafito. "While exciting new pharmaceuticals to treat age-related macular degeneration are now available, these are effective only in a select group of patients, and can be used only during a narrow time window," said Puliafito, an ophthalmologist whose academic focus is macular degeneration. "In contrast, stem cell therapy promises to be broadly applicable. The potential is tremendous."
CIRM President Alan Trounson noted that the disease team approach exemplified by the California Project to Cure Blindness could transform the direction of future research.
"Scientists have talked for years about the need to find ways to speed the pace of discovery," said Trounson. "CIRM, through the Disease Team Award Program, has encouraged applicants to form teams composed of the best researchers from around the world. The partnership between the California Project to Cure Blindness and Britain's Medical Research Council is a great example of CIRM's vision of a new standard for funding translational research."
