About this study

The objective of this study is to compare the areas designated as elevated retinal pigment epithelium (RPE) by the Cirrus HD-OCT versus those designated as drusen on color fundus photographs (CFPs).

Read the detailed description

This is a prospective, multiple site study. Ocular history and examination will be conducted on consented subjects to determine further participation in the study. Subjects qualified to continue will undergo color fundus photography and imaging of their study eye using the Cirrus HD-OCT.

Questions about this trial

What is this clinical trial studying?

An observational study of Drusen Stage Macular Degeneration, run by Carl Zeiss Meditec, Inc. at 4 sites 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 6 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 25 Jun 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites 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?

To compare area measurements of elevated RPE as observed in the Cirrus HD-OCT versus those designated as drusen on color fundus photographs. (time frame: Study was released before December 1, 2012). 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 NCT01272063, which also lists 9 linked publications.

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 Jun 2013.
