Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Schein symptom score (all 6 questions) of greater than 5,
  • evidence of MGD changes in both eyes (i.e.,
  • lower eyelid secretion quality score greater than 1.0 (0 - 3 scale) OR gland dropout score greater than 1.0 (i.e., greater than 25% of entire lower eyelid) as demonstrated by meiboscopy, and corneal staining of grade 4.0 or greater (0 - 20 scale).

Exclusion Criteria:

  • contact lens wear, use of topical ocular medication other than artificial tears (use of Restasis is specifically excluded),
  • unstable systemic medication use (i.e., anti-histamines, steroids, etc.), recent (within 6 months of study start) ocular trauma or surgery,
  • diabetes, aqueous deficient dry eye (defined as a Schirmer I value (without anesthetic) of < 5 mm of wetting in 5 minutes in either eye), and use of punctal plugs.

-Subjects taking omega 3 fatty acid supplements for dry eye can be included so long as their intake is stable for the prior six months and they meet the inclusion criteria above. -
