Intensive Glycemic Control Did Not Affect Diabetic Eye Changes in 1 Year, reveals research
Researchers have identified in a new study that tight blood sugar control within a period of one year did not have a notable impact on changes in diabetic retinopathy (DR) in patients with type 2 diabetes mellitus (T2DM). Although intensive glycaemic control is universally advised for minimizing the long-term complications of diabetes, its impact on diabetic eye disease in the short term is unclear. This new research offers valuable information, proposing that more stringent control of blood sugar during a 12-month period will not be able to prevent or reverse changes in DR during the same time. The study was published in BMC Ophthalmology by Xinyan Wu and fellow researchers.
There is substantial evidence that tight glycemic control—usually defined as having hemoglobin A1c (HbA1c) values less than 7%—will decrease the risk of diabetes complications, including diabetic retinopathy, over a long term. But whether it is effective to change the trajectory of DR in the short term remains to be seen. Diabetic retinopathy is a prevalent microvascular complication of T2DM and a major cause of blindness globally. The present study sought to establish whether attempting more intensive HbA1c targets influenced DR changes during 1 year, according to comprehensive eye evaluation and standardized grading schemes.
