An eye care professional can help locate and make referrals to low vision and rehabilitation services and suggest devices that may help make the most of remaining vision. But it does keep it from getting worse. However, close monitoring is essential. How can people with diabetes protect their vision? Blood vessels in and behind the retina nourish the macula. Hypertensive retinopathy — Lowering blood pressure often can stop ongoing damage to the retina. Sometimes these vessels swell and leak fluid or even close off completely. By examining it, a doctor can inspect a sample of the body’s blood vessels and detect early signs of complications of diabetes or high blood pressure, as well as many other diseases e.g., sickle cell disease, anaemia, lupus. Irish researchers from GUI Galway and Queen’s University Belfast are part of an international collaboration who are assessing if stem cells derived from bone marrow can control glucose levels and stop some of the damage caused by six diabetic complications, including diabetic retinopathy. For example, researchers are harnessing a technology called adaptive optics A to improve imaging techniques such as OCR.
And if you do develop a major problem, there are treatments that often work well if you begin them right away. These conditions include diabetic retinopathy, diabetic macular enema DBE, cataract, and glaucoma. The procedure is used to treat severe bleeding into the vitreous, and is performed under local or general anaesthesia. Good controls of blood sugar levels and blood pressure minimizes the risks of developing retinopathy and can slow progression of the condition. Because diabetic retinopathy often goes unnoticed until vision loss occurs, people with diabetes should get a comprehensive dilated eye exam at least once a year. He or she looks for pale or white areas of the retina. The damaged vessels can have bulges in their walls aneurysms, they can leak blood into the surrounding jellylike material vitreous that fills the inside of the eyeball, they can become completely closed, or new vessels can begin to grow where there would not normally be any: although these new blood vessels are growing in the eye, they cannot nourish the retina and they bleed easily, releasing blood into the inner region of the eyeball, which can cause dark spots and cloudy vision. The NEI-sponsored Diabetic Retinopathy Clinical Research Network compared Avastin, Lucentis, and Eylea in a clinical trial. What are the symptoms of diabetic retinopathy? However, patients who started the trial with 20/50 or worse vision had greater improvements in vision with Eylea. http://www.edwardscohousing.org/experteyesurgeon/2016/08/29/some-emerging-facts-on-rational-eye-surgery-methods/
The researchers analyzed data on people participating in a larger randomized trial known as PREDIMED, which ran from 2003 to 2009 in Spain and tested a Mediterranean diet with added extra virgin olive oil or nuts against a usual comparison diet for preventing heart problems over time. About 3,600 adults aged 55 to 80 who took part in PREDIMED had type 2 diabetes and the analysis focused on them. More on this… Exercise prescriptions important for Type 2 diabetes Based on food frequency questionnaires, the researchers determined that three quarters of these participants had met target omega-3 fatty acid intake levels of 500 mg per day, which can be achieved by meeting American Heart Association guidelines of two weekly servings of fish, preferably oily fish like salmon. Over about a six-year follow-up period, there were 69 new cases of sight-threatening diabetic retinopathy. People who were meeting omega-3 fatty acid guidelines when the study began were 48 percent less likely to have this diagnosis during the study than others, according to the findings published in JAMA Ophthalmology, August 18. It’s hard to say whether the results would have been the same with omega-3 supplements, said lead author Aleix Sala-Vila, a researcher with CIBERObn (Spanish Biomedical Research Center in Physiopathology of Obesity and Nutrition) in Madrid and IDIBAPS at Hospital Clinic in Barcelona. But there have been encouraging results from several research teams studying dietary intake of omega-3 fatty acids and vision for all people, not just those with diabetes, he said. “The incidence of diabetes mellitus type 2 is increasing, and therefore more individuals will suffer from diabetic complications which, if not properly managed, may lead to permanent eye damage,” Sala-Vila said by email. no data”People should be aware that regarding diet, even small changes in the right direction can lead to substantial benefit for themselves,” he said.
