    Also called Handheld swept source (SS) optical coherence tomography (OCT)

    Assessment of retinal thickness.

  • SD-OCTDiagnostic test

    Assessment of retinal structure.

What is being measured

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

  1. Evaluation of the RHMS-RTM retinal thickness measurements

    To evaluate the ability of the RHMS-RTM device to measure retinal thickness

    Measured: 1 day

  2. RHMS-RTM repeatability

    To assess repeatability of the RHMS-RTM device

    Measured: 1 day

  3. Comparison of retinal thickness measurements between the RHMS-RTM and the SD-OCT

    To evaluate the agreement of measurements by the RHMS-RTM and SD-OCT

    Measured: 1 month

Questions about this trial

What is this clinical trial studying?

An observational study of Macular Edema and Macular Degeneration, run by Kubota Vision Inc. 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 11 inclusion and 5 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The record says: withdrawn, as of the sponsor's last update on 21 Feb 2021. 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The study was withdrawn before enrolling participants, so there are no results.

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?

Evaluation of the RHMS-RTM retinal thickness measurements (time frame: 1 day). The study lists 3 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 21 Feb 2021; AzTrials last refreshed its copy on 6 Nov 2026.
