Our project investigates the new characteristics of diabetic retinopathy using liquid eye biopsy in combination with novel parameters of glucose control obtained with continuous glucose monitoring. This approach will bring new knowledge and implications for future therapies.
Diabetic retinopathy is one of the most common causes of blindness in developed countries. The short-term glucose fluctuations have been suggested as a factor contributing to the risk of diabetic complications including ocular complications. We hypothesize that modulatory and other biological abilities of miRNAs and inflammatory chemokines/cytokines have a significant impact on the development and the progression of diabetic retinopathy. Our main goal is to identify the biomarkers that will in time be used for new screening, diagnostic, and treatment strategies for patients with diabetic retinopathy, bring a better prevention and early treatment to them and thus improve their quality of life while saving the cost associated with advanced forms of retinopathy.
