Smoking, hypoglycemia, kidney function tied to vision loss in type 2 diabetes

Key clinical point: Smoking cessation and management strategies to avoid severe hypoglycemia and preserve kidney function may offset vision loss in people with type 2 diabetes.

Major finding: Baseline smoking (odds ratio, 3.17; 95% confidence interval, 1.15-8.76), prior severe hypoglycemia (5.59; 1.32–23.61), and urinary albumin-creatinine ratio (1.42; 1.09-1.84) had higher odds of vision loss during follow-up.

Study details: A prospective, longitudinal study of 1,551 participants with type 2 diabetes, followed for 4 years.

Disclosures: The study was supported by the National Health and Medical Research Council of Australia. The authors reported no conflicts of interest.
