About this study

Official title: A Prospective, Comparative, Observational Study on Spectral-domain Optical Coherence Tomography of the Eye

An increasing number of clinical studies on SD-OCT of ocular pathologies and potential new clinical applications has recently been published in the peer-reviewed literature. However, the successful use of SD-OCT in routine clinical use depends upon the diagnostic sensitivity, biometric accuracy and reliability of the SD-OCT machines. This prospective, comparative, observational study aims to evaluate the imaging quality and diagnostic performance of two commercially available SD-OCT machines for both the anterior and posterior segment of the eye.

Medical subject headings
Corneal Diseases, Macular Edema, Diabetes Mellitus

What is being measured

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

  1. Sensitivity as the proportion of anatomical structures that are detectable with the two instruments

    Anatomical structures include e.g. sublayers of the cornea, sublayers of the retina, retinal vessels etc.

    Measured: 6 months

Secondary outcomes (2)
  1. Corneal sublayer thickness (µm) and retinal sublayer thickness (µm) obtained with the two study instruments

    Comparability is analyzed between various biometric values obtained with the two instruments and typical indices of comparability are produced (e.g. intraclass correlation coefficient)

    Measured: 6 months

  2. Corneal sublayer thickness and retinal sublayer thickness obtained with the two study instruments

    Repeatability for various biometric values obtained with the two instruments is analyzed and typical indices of repeatability are produced (e.g. coefficient of variation)

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

An observational study of Cornea and Retina, run by Augenabteilung Allgemeines Krankenhaus Linz at 1 site in Austria.

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 25 inclusion and 3 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: status not confirmed, as of the sponsor's last update on 25 Nov 2015. 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 Austria. 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?

Results are not available in the source record.

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

Contact Nikolaus Luft, MD (+43 732 7806 ext. 1050, nikolaus.luft@akh.linz.at), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Sensitivity as the proportion of anatomical structures that are detectable with the two instruments (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02614625, which also lists 1 linked publication.

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 25 Nov 2015.
