The Dry Eye Inflammatory Cycle: Understanding Key Triggers
Breaking the Cycle for Lasting Relief
Dry eye disease is often more than just occasional irritation — it's a complex condition driven by a cycle of inflammation that worsens symptoms over time. Understanding the different factors that contribute to this cycle is key to stopping it effectively.
Here’s how common triggers — like rosacea, meibomian gland dysfunction (MGD), diabetes and autoimmune diseases, and increased screen time — each play a unique role in fueling inflammation and dry eye discomfort.
​
1. Rosacea and Inflammation
Rosacea, particularly ocular rosacea, is a powerful driver of inflammation in and around the eyes. This condition triggers:
✅ Chronic eyelid inflammation that disrupts healthy tear production.
✅ Dilation of blood vessels (telangiectasia) that release inflammatory mediators, worsening irritation.
✅ Increased presence of Demodex mites, which thrive in inflamed skin and eyelid margins, further irritating the eyes.
✅ A higher risk of meibomian gland dysfunction (MGD), reducing vital oil production and making tears evaporate faster.
​
2. Meibomian Gland Dysfunction (MGD) and Inflammation
MGD is one of the most common causes of dry eye and plays a major role in sustaining inflammation. It contributes to the cycle by:
✅ Clogging the meibomian glands with thickened oils, reducing tear stability.
✅ Triggering dryness that irritates the ocular surface, causing the body to release inflammatory mediators in response.
✅ Creating a breeding ground for bacteria and Demodex mites, which increase irritation and redness.
✅ Causing gland atrophy over time, worsening symptoms if left untreated.
​
3. Diabetes and Autoimmune Diseases in the Inflammatory Cycle
Systemic conditions like diabetes, rheumatoid arthritis, SjÓ§gren’s syndrome, and thyroid disorders can worsen dry eye by:
✅ Increasing baseline inflammation throughout the body, which impacts the eyes.
✅ Damaging the lacrimal glands (which produce the watery layer of tears) and the meibomian glands.
✅ Increasing tear osmolarity (salt imbalance in tears), irritating the ocular surface.
✅ Slowing the body’s natural healing response, making inflammation harder to control.
​
4. Screen Time and Inflammation
Excessive screen use is a major contributor to modern dry eye symptoms. It drives inflammation by:
✅ Reducing your blink rate by 50% or more, limiting how often your tears are replenished.
✅ Increasing incomplete blinks, which fail to spread the tear film evenly across the eye.
✅ Causing faster tear evaporation, leaving the ocular surface exposed and vulnerable.
✅ Computer Vision Syndrome can worsen irritation and trigger inflammatory responses.
Breaking the Inflammatory Cycle
While each of these factors contributes to dry eye differently, the resulting cycle is similar — irritation leads to inflammation, which worsens gland dysfunction and tear instability. To stop the cycle, treatment must address both the root cause and the resulting inflammation.
At Hi-Line Eye Care, we use a combination of therapies to break this cycle and restore your comfort:
✅ Intense Pulsed Light (IPL) Therapy to calm inflammation, reduce abnormal blood vessels, and improve gland function.
✅ Radiofrequency (RF) Therapy to melt thickened oils, clear blocked glands, and improve tear stability.
✅ ZEST (Zocular Eyelid System Treatment) for deep eyelid cleansing to remove debris, biofilm, and Demodex mites.
✅ Prescription Anti-Inflammatory Drops to reduce irritation and protect the ocular surface.
✅ Lifestyle Guidance to improve habits that reduce inflammation over time.
