About this study
Precision of OCT- and OCTA-based Ocular Measurements
Read the detailed description
The purpose of this study is to assess precision of measurements of vascular structures and the anatomical structures of the posterior pole of the eye based on OCTA and OCT scans in normal subjects, glaucoma patients, and retina patients, and to assess measurements of corneal layers based on corneal OCT scans in normal subjects and cornea patients.
- Conditions
- Normal Eyes and Ocular Pathology
- Being tested
- SD-OCT
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
SD-OCTDevice
Spectral Domain Optical Coherence Tomography for non-invasive, light-based, cross-sectional imaging of ocular structures
| Study group | Role | What they receive |
|---|---|---|
| Normal | no glaucoma or retinal pathology or corneal conditions Receives: Device: SD-OCT | |
| Glaucoma | diagnosis of glaucoma Receives: Device: SD-OCT | |
| Retina | diagnosis of AMD, DR or other retinal pathology Receives: Device: SD-OCT | |
| Cornea | wear contact lens or prior refractive surgery or having dry eye or KCN Receives: Device: SD-OCT |
What is being measured
The primary outcome is the main question the study is designed to answer.
Repeatability and Reproducibility Standard Deviation of ocular measurements
calculated value minus the measured value
Measured: Day 1
Secondary outcomes (1)
Repeatability and Reproducibility Coefficient of Variation of ocular measurements
maximum difference that is likely to occur between repeated measurements
Measured: Day 1

Questions about this trial
What is this clinical trial studying?
An observational study of Normal Eyes and Ocular Pathology, run by Optovue 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 4 inclusion and 4 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 3 Sep 2019. 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. 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?
Repeatability and Reproducibility Standard Deviation of ocular measurements (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 3 Sep 2019.
