About this study

Official title: Analysis of the Diagnostic Performance of LacryDiag, a New "All-in-one" Non-contact Analyzer of the Ocular Surface in the Dry Eye. Study LACRYMOSA

LacryDiag is a new Conformity European (CE) marked diagnostic imaging device devoted to the analysis of the ocular surface. It is an "all in one" device that provides 4 data: non-invasive break-up time (Non-Invasive Break-Up-Time (NIBUT) without fluorescein eye drop); height of the Tear Meniscus (TM); an infrared image of the meibomian glands; a picture of the lacrimal film by interferometry. it's performance will be compare between in diagnosing dry eye syndrome with the standard clinical evaluation, in 80 patients suffering from dry eye diseases and followed at the consultation of the Ophthalmology department of the University Hospital of Saint-Etienne.

Read the detailed description

The primary purpose of this study is to compare the value of Break-Up-Time (BUT) between Non-Invasive Break-Up-Time (NIBUT) measured by LacryDiag and Standard Break-Up-Time (SBUT) measured by usual practice.

What participants receive

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

  • Time #1: Non Invasive Break-Up Time (NIBUT)Diagnostic test

    Also called LacryDiag, Complete diagnosis of dry eyes

    A LacryDiag examination without dye will be realized. All measurements are made without contact. It's calculates the Non Invasive Break-Up Time (NIBUT), Tear Meniscus (TM) height (in millimeters) and number of Meibomian Gland.

    These are different pictures taken with LacryDiag and analyzed.

  • Time #2: MicroInstillation Break-Up Time (MIBUT) + Oxford scoreDiagnostic test

    The MicroInstillation of fluorescein Break-Up Time (MIBUT) will be calculated by manual MIBUT and LacryDiag MIBUT.

    The Oxford score will be calculated. It's used to clinically determine the severity of dry eyes with minimum score at 0 (none) and maximum score at 5 (very severity).

  • Time #3: Standard Break-Up Time (SBUT)Diagnostic test

    The Standard Break-Up Time (SBUT) with fluorescein macroinstillation will be calculated by manual SBUT and LacryDiag SBUT.

  • Time #4: Schirmer testDiagnostic test

    The Schirmer test will be performed. It consists of applying the end of a small strip of blotting paper behind the lower eyelid and examining the strip after 5 minutes.

  • Satisfaction questionnaire to the patientDiagnostic test

    A satisfaction questionnaire to the patient will be completed at the end of the participation at the study.

What is being measured

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

  1. Break-Up-Time (BUT)

    Comparison of Break-Up-Time (BUT) measured by 2 methods : LacryDiag Non Invasive Break-Up Time (NIBUT) and manual Standard Break-Up Time (SBUT).

    Measured in seconds by time#1: Non Invasive Break-Up Time (NIBUT) and time#3: Standard Break-Up Time (SBUT).

    Measured: Day: 1

Secondary outcomes (5)
  1. Standard Break-Up Time (SBUT)

    Comparison of Standard Break-Up Time (SBUT) between LacryDiag SBUT results and manual SBUT results. Measured in seconds.

    Measured by time#3: Standard Break-Up Time (SBUT).

    Measured: Day: 1

  2. MicroInstillation Break-Up Time (MIBUT)

    Comparison of MicroInstillation Break-Up Time (MIBUT) between LacryDiag MIBUT results and manual MIBUT results.

    Measured in seconds by time#1: Non Invasive Break-Up Time (NIBUT) and time#2: MicroInstillation Break-Up Time (MIBUT).

    Measured: Day: 1

  3. Tear Meniscus (TM) height and Schirmer test

    Correlation between Tear Meniscus (TM) height (in millimeters) and Schirmer test (in millimeters).

    Measured by time#1: Non Invasive Break-Up Time (NIBUT) and time#4: Schirmer test.

    Measured: Day: 1

  4. Percentage loss of Meibomian Gland.

    Measured by time#1: Non Invasive Break-Up Time (NIBUT).

    Measured: Day: 1

  5. Thickness (in nanometer) and regularity of lacrimal film (type)

    Correlation between measure thickness (in nanometer) and regularity of lacrimal film (type).

    Measured by time#1: Non Invasive Break-Up Time (NIBUT).

    Measured: Day: 1

Questions about this trial

What is this clinical trial studying?

A study testing Time #1: Non Invasive Break-Up Time (NIBUT), Time #2: MicroInstillation Break-Up Time (MIBUT) + Oxford score and Time #3: Standard Break-Up Time (SBUT) in people with Dry Eye, run by Centre Hospitalier Universitaire de Saint Etienne at 1 site in France.

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 3 inclusion and 7 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: finished, as of the sponsor's last update on 9 Sep 2020. 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 France. 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. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Break-Up-Time (BUT) (time frame: Day: 1). 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 9 Sep 2020.
