Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 90 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: No eye disease.

Who may be able to join

  • Subject is not an employee of the eye clinic.
  • Age ≥18 to 90.
  • Able and willing to undergo the test procedures, give consent, and to follow instructions.
  • Healthy eye without prior intraocular surgery (except cataract surgery and Lasik) and without clinically significant vitreal, retinal or choroidal diseases, diabetic retinopathy, or disease of the optic nerve.
  • Caucasian decent (self-reported).
  • Negative history of glaucoma.
Show all 12Show fewer
  • Intraocular pressure ≤21mmHg.
  • Best corrected visual acuity ≥0.5.
  • Refraction between +6 and -6 diopters and astigmatism ≤ 2 diopters.
  • Normal visual field with Glaucoma Hemifield Test and Mean Deviation within normal limits.
  • Clinically normal appearance of the optic disc, with normal appearing neuroretinal rim with respect to color and shape. The optic disc is examined ophthalmoscopically and by evaluation of stereo photographs.
  • When both eyes are eligible, both eyes enter the study for inter-eye asymmetry; one randomly selected eye will be used for all other measures.

Who cannot join

  • Unreliable visual field. The reliability indices should be used as guide as well as the perimetrist's notes.
  • Unusable disc stereo photos.
  • Inability to undergo the tests.
  • Insufficient quality of Spectralis OCT images (this is not determined until after Spectralis OCT examination, and is an unusual circumstance). Minimum requirements are:
  • Retina completely included in image frame,
  • Quality Score ≥ 20 in the stored ART mean images, and
  • For ONH-R scan: Center position error ≤ 100 μm.
  • Note: Inability of a subject to perform one of the two scan patterns or insufficient image quality in one scan pattern does not exclude the subject or eye from the study.

About this study

Official title: Optical Coherence Tomography (OCT) Data Collection Study "S-2012-1 Norm-cc"

Collect OCT data to evaluate the range and age trend of ocular measurements.

Read the detailed description

This is a prospective, multi-center study. Ocular history and examination will be conducted on consented subjects to determine further participation in the study. Subjects qualified to continue will undergo imaging of both eyes using the SPECTRALIS OCT.

What is being measured

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

  1. Primary Endpoints

    The primary endpoints are the structural measurement values of (1) the ONH, (2) the peri-papillary RNFL, and (3) the macula obtained using the Spectralis OCT and the statistical descriptors such as mean, standard deviation, and distribution percentiles.

    Measured: 3 months

  2. Bruch's Membrane Opening - Minimum Rim Area, Global

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

An observational study of Glaucoma, run by Heidelberg Engineering GmbH at 1 site in Canada.

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 12 inclusion and 8 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 19 Dec 2016. 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 Canada. 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?

Yes. Results are posted in the registry (first posted 19 Dec 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Primary Endpoints (time frame: 3 months). The study lists 2 primary outcomes in all. 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 19 Dec 2016.
