Summary

This study seeks to explore the relevance of inflammation in dry eye patients with MGD and compare the efficacy of LipiFlow treatment followed by lid hygiene and lubricant treatment with Systane Ultra or LipiFlow treatment followed by lid hygiene and lifitegrast treatment in patients with meibomian gland dysfunction.

Detailed description

The role of inflammation as a central mechanism of pathophysiology in dry eye disease has been well documented, including both clinical and basic science studies. It has been estimated that 50-75% of patients complaining of dry eyes have meibomian gland dysfunction (MGD). As defined by TFOS DEWs II MGD is a chronic, diffuse abnormality of the meibomian glands, commonly characterized by terminal duct obstruction and/or qualitative/quantitative changes in the glandular secretion. This may result in the alteration of the tear film, symptoms of eye irritation, clinically apparent inflammation, and ocular surface disease. It has been estimated that 86% of patients complaining of dry eye disease demonstrate meibomian gland dysfunction. The role of ocular surface inflammation vs. the role of obstructive meibomian gland disease is less well understood. The symptoms of MGD (evaporative dry eye) may be difficult to differentiate from those of dry eye syndrome (aqueous deficient dry eye (ADDE)), though MGD patients tend to report more burning and stinging than they report complaints of grittiness, sandiness or foreign body sensation in the eyes. However, there is a significant lack of association between signs and symptoms in patients with dry eye disease, which makes it extremely difficult to sort out which patients would benefit from which treatment options. Given the high prevalence of dry eye in the general population any attempt to segregate patients into appropriate treatment types is important. Traditional treatment options for MGD include the use of artificial lubricants (some lipid-containing such as Systane Ultra), warm lid compresses using cloths or heat pads of various materials, systemic tetracyclines and episodic treatment with topical antibiotics or antibiotic/steroid combinations. Eyelid thermal pulsation procedures (e.g. LipiFlow) have helped many patients. Only one published study supports the benefit of anti-inflammatory treatment (lifitegrast) in patients with MGD. This study seeks to explore the relevance of inflammation in dry eye patients with MGD and compare the efficacy of LipiFlow treatment followed by lid hygiene and lubricant treatment with Systane Ultra or LipiFlow treatment followed by lid hygiene and lifitegrast treatment in patients with meibomian gland dysfunction.
