Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Diabetic retinopathy (DR) is the most common visual complication of diabetes. Risk factors for developing DR are diabetes duration, glycemic control, and hypertension . The prevalence ranges from 17 to 61% according to the diabetes duration .

Obstructive sleep apnea syndrome (OSAS) is very frequent in Type 2 Diabetes population, reaching a prevalence of 23-48% .

Few is known about the exact role of OSAS in the development of DR. A recent study has shown that OSAS is an independent predictor for the progression to pre-/proliferative DR. The purpose of the present study is to assess if the presence of OSA in diabetic patients is a predictive factor for DR occurrence.
