Summary

Dry eye disease (DED) is a common condition that causes ocular discomfort and reduces visual acuity. The two categories of DED are evaporative dry eye and aqueous deficient dry eye. Both conditions can involve pathology of the meibomian glands, lacrimal glands, lids, tear film and surface cells. Meibomian gland dysfunction (MGD) is the leading cause of evaporative dry eye and contributes to aqueous deficient dry eye. The goal of MGD therapy is to provide long term improvement of symptoms for patients by improving the quality of meibum, increasing meibum flow, improving tear film stability and decreasing inflammation. Commonly used therapies include preservative free drops, omega-3 fatty acid supplementation, topical cyclosporine, serum tears, topical azithromycin, oral doxycycline, moisture chambers, intraductal probing, lib margin exfoliation, automated thermal pulsation, warm compresses, among other. Despite this variety of symptoms, patients often do not experience complete or long term relief of symptoms. Forced meibomian gland expression (MGX) has been shown to be an effective method of rehabilitating meibomian glands and improving dry eye symptoms. The eyelid margins are forcefully compressed to express gland contents. Research has shown improvement in patient symptoms with the use of MGX. Intense pulsed light (IPL) have been used in dermatology to treat various conditions. Patients with DED who have tried other therapies and found no relief, often resort to IPL as a last resort. Research has shown IPL alone may be effective in improving patient symptoms. In addition, such studies have failed to show significant adverse events with the use of IPL. Here, we propose a prospective, randomized, case controlled clinical pilot study to examine the efficacy for both subjective and objective measures. 20 patients with DED will be recruited and will be randomly assigned to one of two groups: MGX alone or MGX with IPL. Objective measures will include tear cytokine levels, impression cytology, meibography, tear osmolarity and others. Subjective measures will include quality of life screening tools. We hypothesize that the use of MGX with IPL will lead to greater improvement in subjective dry eye symptoms and objective measures. Given the lack of adverse effects reported in the literature, we do not anticipate adverse effects in our study. Rochester staff Drs. Faustch and Bourne are providing clinical research advice but have no contact with subjects or biospecimens.

Conditions

• Ocular Rosacea
• Dry Eye

Interventions

Type	Name	Description
DEVICE	Intense Pulsed Light Treatment (IPL)	IPL is a high-intensity light source consisting of visible light in the wavelength range of 515-1200 nm, that is aimed at the eyes. Treatments are spaced four to six weeks apart for a total of 4 treatments.
PROCEDURE	Meibomian Gland Expression	Manual expression of the meibomian glands by placing the thumb against the lid margin and press firmly against the eyeball to determine the percentage of meibomian pores that are blocked. This assessment is performed on both the upper and lower lid of each eye.
