About this study

Our primary aim is to determine whether pulsed light therapy (PLT) is effective in reducing symptoms and improving clinical stigmata of dry eye syndrome (DES) associated with meibomian gland dysfunction (MGD) in patients with facial rosacea (which includes ocular rosacea). The uses of PLT are for treatment of rosacea, hair removal, pigmented lesions, and skin telangiectasias. The risks include the potential for transient sunburn-like sensations (i.e. redness, burning sensation) and particularly if not used properly, the potential to cause burns, blistering, scarring, and pigmentary changes.

Read the detailed description

Group 1: pre-existing dry eye treatment regimen + sham light treatment. Sham light treatment will consist of applying the usual eye shields used for PLT, applying the usual skin gel to the facial region, and applying the cooling probe without application of pulsed light therapy treatment.

Group 2: pre-existing dry eye treatment regimen + pulsed light therapy (PLT)

Subjects will be recruited from the outpatient clinics at Bascom Palmer Eye Institute, will have a chief complaint of dry eyes, and will have to meet all inclusion/exclusion criteria. Subjects will be randomized via computerassisted random number generation to Group 1 or 2. All subjects will undergo baseline evaluation for DES including a standardized questionnaire about symptoms of dry eyes (takes about 5 minutes to complete and assesses the presence and severity of dry eye symptoms), various testing on the properties and composition of the tear film, grading of changes related to dry eye seen on the surface of the eye, and grading of the oil glands on the eyelid (meibomian glands) and their secretions. Primary outcomes will be anatomical improvement of the meibomian glands and their secretions.

Subjects in Group 1 will continue their pre-existing dry eye treatment regimen and receive sham light treatment, whereas subjects in Group 2 will continue their pre-existing dry eye treatment regimen and receive PLT. All subjects will come for their initial visit where evaluation and treatment #1 will take place. They will also attend 3 follow-up visits spaced approximately 3-4 weeks apart during which they will have subsequent treatments and/or evaluations for their dry eyes. The visit duration will range from approximately 60-90 minutes per clinic visit.

The PLT devices are FDA approved for the treatment of rosacea in the periocular/facial region, and having facial rosacea is one of the inclusion criteria for this study. This is the indication for treatment with PLT. The devices are not FDA-approved for the treatment of DES, although this is something we will be looking at as one of our main outcomes.

What is being measured

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

  1. Anatomical improvement of the meibomian glands and their secretions.

    We are looking at subjective changes in DES symptomatology based on the OSDI questionnaire score. We are also looking at objective changes in examination findings based on the tear film properties (TBUT, Schirmer), staining patterns of the ocular surface using fluor. and LG dyes, characteristics of the meibomian glands and lid margin (e.g. telangiectasias, notching, myelography by transillumination, etc), as well as the meibum secretions (e.g. expressibility, and consistency).

    Change in baseline for OSDI, TBUT in seconds, Schirmer testing in mm, staining pattern score (standardized proprietary score on a scale of 1-4), myelography by % of meibomian glands that can be transilluminated, expressibility/consistency (proprietary score on scale of 1-4) will be measured.

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

A study testing Pulsed Light Therapy in people with Meibomian Gland Dysfunction and Dry Eye Syndrome, run by University of Miami 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 7 inclusion and 11 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 28 Jun 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?

Anatomical improvement of the meibomian glands and their secretions. (time frame: 3 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 28 Jun 2018.
