About this study

Official title: Scanning Laser Ophthalmoscopy Registered Optical Coherence Tomography for Real-Time Eye Tracking

Diabetic retinopathy (DR) is a leading cause of vision loss in working age Canadians. Current treatment consists of early detection and laser photocoagulation therapy for preventing progressive or severe vision loss. Microaneurysms (MA) are the earliest, clinically visible changes of DR, which are visualized using specialized imaging technologies. PulseMedica is developing a three-dimensional (3D) retinal imaging system with real-time eye tracking capabilities. The purpose of this study is to assess the feasibility of PulseMedica's prototype device, the OSNAT800 Imaging Only (IO), in providing real-time tracking of eye movements in patients with DR. It is hypothesized that the OSNAT 800 IO will be able to perform real-time eye tracking while imaging patients with DR.

Questions about this trial

What is this clinical trial studying?

A study testing OSNAT 800 IO in people with Diabetic Retinopathy and Retinal Imaging, run by PulseMedica 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 4 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: finished, as of the sponsor's last update on 25 Jan 2024. 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?

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?

Successful performance of the real-time eye tracking function by post-image processing (time frame: Through study completion, an average of 6 months). 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 25 Jan 2024; AzTrials last refreshed its copy on 7 Nov 2026.
