Abstract

Purpose: Obstructive Sleep Apnea among patients with and without Diabetic Retinopathy. Methods: A Prospective Observational Study of 80 diabetes mellitus patients. Patients at high OSA risk, STOP-Bang score ≥5 and ESS score ≥10) underwent polysomnography. Based on Apnea Hypopnea Index (AHI), OSA was graded as mild (AHI = 5-14/h), moderate (AHI = 15-30/h), and severe (AHI >30/h). Statistical analysis was done using three models of outcome measures: No DR versus any DR, Less severe DR versus More severe DR, and No DME versus DME. Results: Mean age NO DR -56.02 ± 11.046 and DR -53.57±11.67years. Based on the STOP-BANG Questionnaire, No DR-52% and DR 65% were at moderate and high risks. Significant difference was found regarding sex, age, neck size, other chronic diseases, types of DM, use of insulin, fasting blood sugar, mean HbA1c, lipid profile and 24-hour urinary protein. Conclusions: Based on the SBQ, our results indicated a significant relationship between OSA and glycemic control.
