Abstract

Purpose : To determine the degree of vital staining of the cornea and conjunctiva in dry eye (DE) patients following meibomian gland therapy.

Methods : In this observational single-center study, symptomatic DE patients with meibomian gland dysfunction (MGD) underwent modified conventional therapy (2 manual lid expressions per eye during a 3 mo period supplemented with daily moist warm compress therapy; n=16, 32 eyes). Meibomian gland analysis (MGA) scores were determined by assessing 15 lower eyelid glands using the Meibomian Gland Evaluator (TearScience®,Morrisville,NC); secretions were graded as 0=no secretion, 1=inspissated-filamentary, 2=cloudy/turbid liquid, 3=clear liquid. DE patients required MGA scores ≤ 20 for inclusion. Sodium fluorescein (SF) corneal staining and lissamine green (LG) conjunctival staining were graded as 0=none, 1=mild, 2=moderate, 3=severe for 5 corneal and 6 bulbar conjunctival regions. MGA, SPEED, OSDI, osmolarity, lid wiper epitheliopathy (LWE) and TFBUT were determined at baseline (BL) and 3 mo. Average staining of individual corneal and conjunctival tissues was determined in each eye. Tissues were grouped based on staining severity [grade 0=(0-0.49), grade 1=(0.5-1.0), grade 2=(1.01-2), and grade 3=(2.01-3)], where lower grades indicate less severe staining. The percentage of eyes in each severity group was determined.

Results : There were no statistically significant changes in SPEED, OSDI, osmolarity, LWE or TFBUT. MGA scores were significantly increased at 3 mo vs BL (22.81±1.61 vs 13.28±0.97; p=0.0005). SF staining decreased in severity from BL (grade 0: 9.38%, grade 1: 46.88%, grade 2: 31.25%, grade 3: 12.5%) to 3 mo (grade 0: 37.5%, grade 1: 28.13%, grade 2: 25 %, grade 3: 9.38%). LG staining decreased in severity from BL (grade 0: 31.25%, grade 1: 46.88%, grade 2: 18.75%, grade 3: 3.13%) to 3 mo (grade 0: 43.75%, grade 1: 43.75%, grade 2: 12.5%, grade 3: 0%). This represents a nearly 30% increase in the number of patients attaining a grade 0 staining score in the cornea and more than 12% increase in the number of patients attaining a grade 0 score in the conjunctiva at the 3 mo time point.

Conclusions : A 3-mo combined therapy regimen of two manual lid expressions and daily warm compresses improved meibomian gland secretion and decreased corneal and conjunctival staining in dry eye patients with meibomian gland dysfunction.
