Researchers at the Centers for Disease Control and Prevention and the U.S. High blood-sugar levels can damage blood vessels in the retina, the nerve layer at the back of the eye that senses light and helps to send messages to the brain. In 2010, one in every 39 blind people was blind due to DR, which increased 27 percent since 1990. The clinical trial was conducted by the Diabetic Retinopathy Clinical Research Network (DRCR.net), which is funded by the National Eye Institute, part of the National Institutes of Health. Further, the researchers found that during the last 20 years, South Asia, Middle East, North Africa, and West Sub-Saharan African countries showed the highest number of people visually impaired because of diabetic retinopathy. As it progresses, diabetic retinopathy can cause vision loss that in many cases can not be reversed. Over a four-year period, researchers took retinal photographs that recorded any changes in the blood vessels and the progression of retinopathy.
Anti-cancer drugs may also used to treat the disease. Besides, they must know how to control the blood sugar levels. The good news is that, for the last 20 years, many diabetes care professionals, equipment manufacturers, and people with visual impairment have been working tirelessly to address these challenges. However, everything else linked to a higher risk of nonrefractive vision impairment – such as poverty and lack of education – was the same or better in the later study population compared to the earlier one, the researchers wrote Tuesday in the Journal of the American Medical Association. That means a specialist will assess your current vision, record your vision history and make recommendations about how you can use your remaining vision to meet your goals. Attending for regular eye screening appointments will significantly improve your chances of avoiding eye problems in the future”, added Sinead. This new volume also highlights the exciting changes and discoveries in vision research and treatment from the past 5 years.
