Trial summary

Meibomian glands (MG) are modified sebaceous glands associated with the tarsus (collagenous structural component) of the upper and lower eyelids. Meibomian glands produce lipid-based secretions which are an integral and stabilizing part of the tear film. Read more about this study

About this study

Meibomian glands (MG) are modified sebaceous glands associated with the tarsus (collagenous structural component) of the upper and lower eyelids. Meibomian glands produce lipid-based secretions which are an integral and stabilizing part of the tear film. In blepharitis and ocular rosacea (two known causes of obstructive meibomian gland dysfunction (o-MGD), inflammation of the lid margins causes blockage of the meibomian gland orifices, changes in glandular secretions, and dropout of the glands themselves. This limits the production, secretion, and quality of meibum. With less oil in the tear film, the aqueous portion of tears is not stable and evaporates quickly which leads to dry eye.

Read the detailed description

Meibomian gland probing is a relatively new, safe, and effective technique for treating obstructive meibomian gland dysfunction (o-MGD). It involves topical anesthesia of the eyelid margins and insertion of a 2 mm or 4 mm sterile, beveled, solid stainless steel probe at the slit lamp. Meibomian gland probing has been reported to alleviate symptoms (lid tenderness / lid margin congestion) of o-MGD (Maskin, 2010). It has also been shown to improve meibum lipid levels, viscosity, and tear breakup time (Nakayama, Kawashima, Kaido, Arita, \& Tsubota, 2015). Though probing has been investigated in a few small studies of o-MGD, only one small study of 10 participants has investigated meibomian gland probing in ocular rosacea (Wladis, 2012). This study showed improvement in ocular surface disease index (OSDI, a standardized questionnaire assessing dry eye) but did not show objective improvement by way of examination findings or analysis of meibum (Wladis, 2012).

In our study, Investigators intend to further investigate meibomian gland probing in participants with diagnosed ocular rosacea. Investigators hypothesize that after probing of one eye, Investigators will note improvements in participants symptoms as reflected in improvement in OSDI scores, Reductions in Inflamma-Dry measures (measure of matrix metalloproteinase (MMP-9), an inflammatory marker elevated in tears of participants with dry eye), decreased tear fluid osmolarity, decreased meibum viscosity on expression . Objective improvement in lid margin disease (noting collarettes, pitting, telangiectasia of lid margins, thickening / irregularity of lid margins, lid margin tenderness; improvement in tear break up time (TBUT); and improvement in corneal fluorescein / lissamine green staining).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • meibomian gland probingProcedure or surgery

    Investigator will do baseline (OSDI) questionnaires prior to probing as well as at 1 week (at home), 1 month, 3months, and 6 months at office visits.

  • Left eye Meibomian Gland Probing Control GroupProcedure or surgery

    There will be no probing in the left eye. This will be used as a control for the right eye.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Improvements in participants symptoms as reflected in improvement in Ocular Surface Disease Index (OSDI) scores

    The OSDI is assessed on a scale of 0 and 100, with higher scores representing greater disability.

    Measured: Up to 6 months

Questions about this trial

What is this clinical trial studying?

A study testing meibomian gland probing in people with Meibomian Gland Dysfunction, run by University of Arkansas at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 26 Apr 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Improvements in participants symptoms as reflected in improvement in Ocular Surface Disease Index (OSDI) scores (time frame: Up to 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Apr 2018.
