A study that will be published in a special supplemental section of the Journal of the Endocrine Society sheds light on a possible link between the loss of the gland in the eyelid that helps to lubricate the eye and elevated blood glucose levels in diabetic patients. Meibomian glands are located in the eyelids and play a critical role in both tear film production and tear film stabilization.
Dry eye and eye pain is a frequent complaint of patients with diabetes and new photography techniques allow eye care providers to easily take images of meibomian glands. Researchers discovered that the loss of these glands occurred more frequently with elevated blood glucose levels. Study participants who had blood glucose levels higher than 5.6 percent also had a greater loss of the meibomian glands.
Researchers note that monitoring the eyelids of patients with diabetes who complain of dry eye and "sand in the eyes" sensation and have them check their blood sugar levels and consult with their ophthalmologist about their eye health.
