Brief Summary
One of the important factors in obtaining successful outcomes when treating severe meibomian gland dysfunction (MGD) is to control the existing ocular and eyelid inflammation. Thus, in previous studies, topical and systemic antibiotics with anti-inflammatory function, such as topical azithromycin, systemic tetracycline, doxycycline and minocycline, have been used to treat severe MGD. In this study, minocycline which had the fewest side effects was used to evaluate the effect on cytokine levels in severe MGD. At study initiation, all patients completed an Ocular Surface Disease Index (OSDI) questionnaire and had an ocular surface, tear, and meibomian gland evaluation that consisted of fluorescein tear break-up time (TBUT), Schirmer test, corneal and conjunctival fluorescein staining, microscopic examination of lid margins and meibomian glands, and tear cytokine levels. All measurements except tear cytokine levels were conducted in the same manner before treatment, after 1 month, and after 2 months of treatment. Tear cytokine levels were evaluated before treatment and after 2 months of treatment. The aim of this research was to determine the concentration of inflammatory cytokines in the tears of patients with MGD and to compare the cytokine levels, corresponding clinical responses, and ocular symptoms before and after 2 months of treatment with oral minocycline.

Outcome Measures
Primary Outcomes (1)
change of inflammatory tear cytokine levels
Thirty microliters of phosphate-buffered saline will be injected into the inferior conjunctival sac using a micropipette. Approximately 20 μL tear fluid and buffer will be collected with a micropipette. Cytokines are measured using the BDTM Cytometric Bead Array (CBA) (BD Bioscience, San Jose, CA). The cytokines analyzed were interleukin (IL)-1β, IL-6, IL-7, IL-8, IL-12p70, IL-17α, interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α), and monocyte chemotactic protein-1 (MCP-1). Flow cytometry will be performed using the BDTM LSRII system (BD Bioscience, San Jose, CA).
