Purpose: To evaluate the relationship between obstructive sleep apnea (OSA) and the presence and severity of diabetic retinopathy (DR).

Methods: Three hundred seventeen patients with International Classification of Diseases diagnoses of both DR and OSA were evaluated retrospectively. Diabetic retinopathy severity and diabetic macular edema status were determined by diagnostic coding and medical records. Obstructive sleep apnea severity and additional sleep measures were obtained from overnight polysomnography. Analysis was performed using multivariable logistic regression.

Results: After adjustment, an association was seen between DR and severe OSA (odds ratio [OR]: 2.18, 95% confidence interval [CI]: 1.14–4.18, P = 0.019). Proliferative DR was associated with severe OSA versus no DR (OR: 2.40, 95% CI: 1.12–5.14, P = 0.024) and mild nonproliferative DR (OR: 2.87, 95% CI: 1.26–6.55, P = 0.012). Comparing all nonproliferative DR with proliferative DR, proliferative DR and severe OSA were associated (OR: 2.20, 95% CI: 1.03–4.70, P = 0.043), as well as diabetic macular edema and severe OSA (OR: 2.89, 95% CI: 1.58–5.27, P = 0.001). No association was seen between DR/diabetic macular edema and secondary sleep measures.

Conclusion: The findings suggest an increased risk of DR, proliferative DR, and diabetic macular edema in patients with severe OSA. Ophthalmologists following these patients should be aware of this association to better manage ocular sequelae of diabetes.

This study examines the relationship between obstructive sleep apnea and the presence and severity of diabetic retinopathy and macular edema using data from diagnostic coding, medical records, and overnight polysomnography. An association between all diabetic retinopathy/proliferative diabetic retinopathy/diabetic macular edema and severe obstructive sleep apnea was found.
