Connection Between Diabetes and Dry Eye Syndrome
Diabetes and dry eye syndrome (DES) are closely linked, with high blood sugar levels playing a significant role in the development of this condition. This connection is primarily due to diabetes' impact on tear production, tear film quality, and ocular surface health.
People living with diabetes, especially those over 65 years old, are at a higher risk of developing DES. In fact, nearly half of people with diabetes have dry eye[1][5]. The severity of symptoms tends to increase with the duration of diabetes and poor glycemic control.
Reduced tear production and quality are key factors in this relationship. Diabetes leads to dysfunction of the lacrimal gland and meibomian glands, which are essential for producing the aqueous and lipid components of tears[1][5]. This gland dysfunction contributes to dry eye symptoms.
High blood sugar also damages corneal nerves, leading to decreased corneal sensitivity and impaired neural regulation of tear secretion. Confocal microscopy studies indicate that diabetic dry eye patients exhibit reduced corneal nerve fiber density and increased nerve abnormalities, which correlate with dry eye severity[3].
Inflammation and immune cell involvement are also part of the equation. Diabetes-related ocular surface inflammation, including immune cell infiltration, affects corneal nerve morphology and further disrupts tear film stability[3].
Tear film instability is another issue. Diabetes reduces tear break-up time (TBUT), indicating increased tear evaporation and instability, worsening dry eye symptoms[1][3].
Managing blood sugar levels and regular ocular surface evaluations are crucial in preventing or treating dry eye syndrome in diabetic patients[1][5]. Common symptoms of dry eye include burning, stinging, gritty sensation, redness, and fluctuating vision, significantly impacting quality of life[4].
It's important to note that diabetes can also contribute to other eye problems, such as diabetic retinopathy. This occurs when high blood sugar levels result in damage to blood vessels in the retina, causing leakage and swelling, and potentially leading to vision problems[2].
Maintaining blood sugar levels within a safe range is important to avoid potential eye problems. A healthcare professional may suggest adopting a moderate weight, following a healthy, balanced diet, and regular exercise to help maintain blood sugars within a safe range[6].
Reducing the risk of dry eye can be achieved by reducing dependence on air conditioning, heating vents, or fans, moving furniture away from air pathways, using digital devices less frequently, taking up blinking awareness training, and quitting smoking[7].
