BY QUINN PHILLIPS | MARCH 10, 2023 Researchers have discovered how hypoglycemia (low blood glucose) may contribute to eye damage in people with diabetes, according to a new study published in the journal Cell Reports. The connection between high blood glucose levels in people with diabetes and a variety of potential complications — including retinopathy and other eye diseases linked to diabetes — is...

DOI: 10.1016/j.celrep.2022.111976 People with diabetes who experience periods of low blood sugar—a common occurrence in those new to blood sugar management—are more likely to have worsening diabetic eye disease. Now, researchers at Johns Hopkins Medicine say they have linked such low blood sugar levels with a...

UNIVERSITY OF HOUSTON As you read this are your eyes burning, itchy, tired, dry or red? If so, you may be one of 21 million people in the United States living with dry eye disease (DED). If you don’t have it now, you may soon – the numbers are expected to rise as the population ages, and as anyone who suffers...

Currently, the only treatment is a corneal transplant, major surgery with associated risks and potential complications. “When you do a transplant you make a huge difference for that person, but it’s a big deal for the patient with lots of visits, lots of eye drops, lots of co-pays, and if you had a medical treatment...

MEDGADGET EDITORS GENETICS, NANOMEDICINE, OPHTHALMOLOGY Wet age-related macular degeneration and a number of other eye diseases, including congenital conditions, are related to mutated genes that result in blood vessel abnormalities. These can be treated with gene therapy, but delivering genetic material has proven to be difficult when dealing with large gene sequences that are common...
