An enzyme under study to treat certain cancers is also showing promise in reducing the significant vision damage that can result from diabetes and premature birth, scientists report.

Inflammation is considered a hallmark of cancer. It’s pervasive as well in both of these potentially blinding eye conditions, in which inadequate oxygen to the eyes prompts growth of new blood vessels to better deliver oxygen, but which instead often obstruct the vision pathway and become leaky, which causes swelling, further hindering vision.

Scientists at the Medical College of Georgia report in newly published studies in the journals Cell Death and Disease and Cells, increasing evidence that making more of the enzyme arginase 1, or A1, available helps alleviate these...

Diabetes is a long-term chronic disease with many complications and requires care over a lifetime. The longer a patient suffers from diabetes, the higher the risk of developing retinopathy which can progressively lead to a decline in vision and even to blindness.

A POSTECH research team led by Professor Sei Kwang Hahn and Ph.D. candidate Geon-Hui Lee (Department of Materials Science and Engineering) in collaboration with Dr. Sangbaie Shin of PHI BIOMED Co. has recently developed a smart contact lens-type wearable device to prevent diabetic retinopathy and treat it in its early stages by irradiating 120 µW far red/LED light to the retina. This technology for smart LED contact lens has attracted a great attention for various ophthalmologic diseases.

Eating oily fish twice a week can protect your eyesight a study has revealed

In middle-aged and older individuals with type 2 diabetes, intake of at least 500 mg/d of dietary long-chain ω-3 polyunsaturated fatty acids, easily achievable with 2 weekly servings of oily fish, was associated with a decreased risk of sight-threatening diabetic retinopathy, according to a study published online by JAMA Ophthalmology.

Given the economic and societal burden of DR, developing effective strategies to prevent or at least delay its onset is a major public health issue. The retina is rich in long-chain ω-3 polyunsaturated fatty acids (LCω3PUFAs). Experimental models support dietary LCω3PUFA protection against DR, but clinical data are lacking.

Lucentis (ranibizumab) has been found to be highly effective for treating proliferative diabetic retinopathy, an eye disease that can occur as a complication of diabetes. The researchers, part of the Diabetic Retinopathy Clinical Research Network, say this is the first major advance in therapy in 40 years.

Diabetic retinopathy is the leading cause of vision loss and blindness among working-age Americans. An advanced stage, called proliferative diabetic retinopathy, occurs when abnormal blood vessels grow near the retina, the light-sensitive tissue at the back of the eye. These new vessels can leak blood, which can obscure vision and damage the retina...
