Substance in tears could be used for diabetes monitoring

Key clinical point: Glycated albumin (glycoalbumin) in tears could someday be a way for those with diabetes to monitor their blood sugar levels noninvasively.

Major finding: Tears and blood were strongly correlated (r = .722; P < .001) even after adjustment for age, gender, nephropathy stage, and obesity.

Study details: A study of 100 patients with diabetes. Tear and blood samples were collected and GA levels measured.

Disclosures: The study was funded by a grant from the Japan Agency for Medical Research and Development. The study’s investigators had no conflicts of interest.
