Researchers at the Oxford Centre for Respiratory Medicine, United Kingdom, studied data and retinal images from 118 men with OSA and Type 2 Diabetes. Researchers found that retinopathy was present in 54% of those who had OSA (obstructive Sleep Apnea),compared to 31% of those without OSA, independent of the effects of Glucose control, age, Body Mass index(BMI) , Blood Pressure and the duration of Diabetes. Further research will try to determine if CPAP therapy, the treatment for OSA can delay the development and progress of Retinopathy, associated with Diabetes.
