AMD treatment with NeoVista system

Wet AMD occurs when abnormal blood vessels behind the retina start to grow under the macula, where they leak blood and fluid, causing scar tissue to form and vision to become impaired. With wet AMD, vision loss may occur faster and be more noticeable than with dry AMD. The longer the abnormal vessels leak or grow, the more detail vision will be lost. The earlier wet AMD is diagnosed, the better the patients' chance of preserving some or much of their central vision. The first European patients have been treated for wet age-related macular degeneration with NeoVista's Vidion ANV Therapy System, an epimacular brachytherapy device that delivers a single dose of therapeutic radiation, the manufacturer announced in a press release. Stanislao Rizzo, MD, of S. Chiara Hospital, Pisa, Italy, treated...

Blood test to identify retinopathy in Type 1 Diabetics

A routine blood test may identify juvenile-onset diabetic patients at heightened risk for proliferative retinopathy.In a multivariate analysis of data on 426 people followed over 18 years from Pittsburgh Epidemiology of Diabetes Complications Study, researchers found that each increment of 1 g/dL in hemoglobin was associated with a linear 29% increase in risk for retinopathy in men with type 1 diabetes (95% CI 8% to 54%), and a quadratic 10% risk increase in women (95% CI 0% to 20%). Notably, only diastolic pressure and glycated hemoglobin were predictive of retinopathy in multivariate analysis for both sexes, while systolic pressure predicted retinopathy in women (HR 1.03 per mm Hg), but not in men.The researchers noted that the difference...

Combined drug to treat nasal and ocular allergies

Image by aarrgh via FlickrA study published in the Annals of Allergy, Asthma, and Immunology and presented at an allergy conference, showed that the combination of azelastine (Astelin or Astepro) and fluticasone propionate (Flonase) gave significantly better nasal symptom relief than placebo or either drug alone. Azelastine is an antihistamine and mast cell stabilizer that is also sold as eye drops for allergic conjunctivitis under another brand name. Fluticasone is a synthetic glucosteroid that is used as an anti-inflammatory.Investigators enrolled 610 patients with moderate-to-severe allergic rhinitis, randomly assigning them to get either azelastine, fluticasone, the combination nasal spray, or a placebo nasal spray twice a day for two...

Role of dietary fat in AMD

MedPage Today reported that, according to a study published in the Archives of Ophthalmology, " fat-filled diet may put younger women at risk for future age-related macular degeneration (AMD).After analyzing dietary fat intake measured in 1,787 women, researchers found that women younger than 75 with the highest total fat intake (about 43% of daily calories) had 70% higher odds of intermediate AMD than those in the lowest quintile (21% fat calories). Notably, photographic assessment for AMD revealed that 4% of the women had intermediate disease -- defined by extensive drusen deposits on the retina or optic nerve head as well as pigmentary abnormalities.But as in some prior studies, macular degeneration risk rose with omega-6 intake (OR 2.0...

Cataract surgery may not speed progression of AMD

Image via WikipediaAccording to a study published in the Nov. issue of the journal Archives of Ophthalmology, cataract surgery doesn't appear to speed the progression of age-related macular degeneration (AMD).Investigators examined 71 eyes of patients with non-neovascular AMD before, and at one week and one year after they had cataract surgery. They discovered progression to neovascular AMD occurred in 4.6 percent of the eyes between one week and one year after cataract surgery, compared with three percent for cataract-free eyes. Medscape reported that an accompanying editorial by Barbara E. K. Klein, MD, MPH pointed out that several reports have shown an association between cataract surgery and AMD since the late 1980s, and that...

HbA1c better predictor retinopathy than FPG in US population

According to a study published in Diabetes Care, glycated hemoglobin (HbA1c) is a better predictor of retinopathy prevalence in the general population than fasting plasma glucose (FPG). Diabetes is a disease that occurs when the pancreas does not secrete enough insulin or the body is unable to process it properly. Insulin is the hormone that regulates the level of sugar (glucose) in the blood. Diabetes can affect children and adults. Patients with diabetes are more likely to develop eye problems such as cataract or glaucoma., but the main threat to vision is its effect on the retina.Researchers analyzed data from 1,066 people, including values for HbA1c, FPG, and 45 degree color digital retinal images. After using...

A novel, "dual optic" accommodating intraocular lens improved intermediate distance vision and contrast sensitivity under low light conditions compared with some multifocal lenses, researchers said.The findings, reported in two studies from the same research group here at the American Academy of Ophthalmology meeting, suggest that the new generation of lens will hold functional advantages for patients undergoing cataract surgery.First generation monofocal lenses were often used to create "bifocal" vision, with the lens in one eye set for distance vision and the other set for near objects. To overcome the poor depth perception this created, the next generation of multifocal lenses allowed both eyes simultaneously to focus on far or near objects...

Gene therapy may improve vision in Leber's congenital amaurosis

The CBS Evening News reported that there is good news for the more than 10 million Americans who suffer from some type of vision disorder. In an experimental gene therapy trial at the Children's Hospital of Philadelphia, researchers used DNA from a DNA bank to create a functioning gene that was missing in 12 patients who were legally blind. The gene was then injected into the eye with a thin needle, which created a missing protein inside the faulty retina, helping to restore vision. The Los Angeles Times reported that the finding, published in the Lancet, suggests it may be possible to produce similar improvements in a much larger number of patients with retinitis pigmentosa and macular degeneration. The participants had Leber's congenital...

Retinal changes may be associated with Alzheimer's

Neuroscientists at the University of California-Irvine have discovered that the retinas of laboratory mice, whose genes have been altered so they develop Alzheimer's disease, experience changes similar to those in the brains of humans who have the disease. Alzheimer's, affects over 5 million people in the U.S. and is the leading cause of elderly dementia. Brain imaging techniques are useful, but retinal imaging could be less invasive, less expensive and easier to perform.For a study appearing in the November issue of The American Journal of Pathology, UCI neuroscientist Zhiqun Tan and colleagues analyzed the retinas of Alzheimer's mice that had been treated with immunotherapy.Specifically, in both the retinas and brains, there is an accumulation of amyloid plaque lesions, a hallmark of the...

Michigan considering doctor's tax.

First the Auto Industry; now the medical profession. Michigan has a great plan to move the rest of the population to the other 49 states!The AP reports, "Debate continues over whether Michigan should put a three percent tax on doctors' gross receipts to raise more money for low-income healthcare programs" as the Republican-led state Senate held a hearing on the issue. Opponents say the tax would drive doctors out of the state and reduce access to healthcare, but supporters say the tax would give physicians who see Medicaid patients higher reimbursement rates instead of the 8 percent cut contained in Michigan's current budget plan. Michigan doctors warn new tax may hurt their business. Michigan's Howell Daily Press & Argus...

visuospatial skills decline three years before Alzheimer's

HealthDay reported that, according to a study published in the Oct. issue of the Archives of Neurology, the ability to perceive relationships between objects (visuospatial skills) may decline years before a person is diagnosed with Alzheimer's disease. In a study population of 444 people, researchers from the University of Kansas used data from "cognitive assessments" to chart declines in various areas before participants were diagnosed with dementia. They found an inflection point (sudden change to a steeper slope of decline) in visuospatial abilities three years before clinical diagnosis of dementia. After that, "declines in overall cognition occurred the next year, while inflection points for verbal and working memory weren't seen...

AMD associated with lipoprotein build-up at back of retina

Age-related macular degeneration (ARMD) is a major cause of vision loss in the elderly and exists in two forms “wet” and “dry.”In the “wet” form, abnormal blood vessels behind the retina grow into the macula, and can separate it from the rest of the retina leading to sight-threatening complications.The “dry” form of the disease is much more common, but until recently was poorly understood. A leading research team in this area, led by Christine Curcio (University of Alabama School of Medicine, Birmingham, USA) summarizes current knowledge in a review published in the Journal of Lipid Research.A build-up of lipoprotein particles at the back of the retina, similar to the build-up of cholesterol in coronary arteries, may play a key role in the...

Handheld device detects blindness in infants

A new handheld device, developed in part by biomedical engineers at Duke University Medical Center, uses spectral domain optical coherence tomography to allow doctors to look for retinopathy of prematurity in infants, a condition that could lead to blindness. The new device developed by Bioptigen, which creates a 3D image of the back of the eye, can even be taken to infants in the neonatal ICU, and can be used without ever touching an infant's eye. Researchers now say that it's time to determine what role the imaging could play in treatment decisions.Duke Eye Center ophthalmologist Cynthia Toth compares the process to inspecting fish from the side of an aquarium instead of through an ocean's murky surfa...
