Glaucoma Patients and Healthy ControlsNCT01293474
Choroidal Thickness in Glaucoma Patients and Healthy Controls
An observational study of Glaucoma Patients and Healthy Controls, run by University of Zurich at 1 site in Switzerland.
Trial summary
With the new software tool (EDI, enhanced depth imaging) of the Spectralis® spectral-domain optical coherence tomography (SD-OCT) it is possible to visualize and measure the choroidal thickness. In glaucoma a vascular component is known. Read more about this study

About this study
With the new software tool (EDI, enhanced depth imaging) of the Spectralis® spectral-domain optical coherence tomography (SD-OCT) it is possible to visualize and measure the choroidal thickness. In glaucoma a vascular component is known. Therefore a difference of choroidal thickness in glaucoma patients and healthy controls is proposed.

Questions about this trial
What is this clinical trial studying?
An observational study of Glaucoma Patients and Healthy Controls, run by University of Zurich at 1 site in Switzerland.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
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 6 Jan 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 Switzerland. 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?
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?
COV (time frame: t0). 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 6 Jan 2015.
