Trial Outcomes & Findings for Meibography and Tear Scan Using the Oculus Keratograph 4 (NCT NCT01382108)

NCT ID: NCT01382108

Last Updated: 2013-11-26

Results Overview

Assessments will be made in normal participants (no MGD) and participants with MGD and compared between the two groups at baseline and after the use of a meibomian gland evaluator. The meibomium gland dropout score subjective grading scale: 0 = no loss of mebomium glands 1. = area of meibomium gland loss less than 33% 2. = area of meibomium gland loss between 33% and 67% 3. = area of meibomium gland loss more than 67%.

Recruitment status

COMPLETED

Target enrollment

39 participants

Primary outcome timeframe

Before and after the use of a meibomian gland evaluator. Assessments will be separated by a period of at least 10 minutes.
