About this study

Official title: Investigation of the Accuracy of a Self-testing Diagnosis Imaging Model for Diabetic Retinopathy

This is a prospective clinical study. At the Shaoguan Diabetic Eye Screening Programme, patients ages 30-80 will undergo the two diagnostic models: (1) in a remote diagnostic clinic site, patients undergo a self-testing device that provides both color retinal photography (CRP) and optical coherence tomography (OCT) imaging of nondilated pupils, and receive an online consultation provided by a retinal specialist; (2) on a separate day, patients visit the tertiary hospital, undergo traditional imaging of dilated pupils acquired by a non-expert imager using a traditional CRP imaging device at the point of care, and receive a face-to-face consultation provided by a retinal specialist.

Within one week of receiving both diagnostic imaging services, patient preferences are assessed and they decide which diagnostic imaging model is preferred.

Being tested
Full Self-Diagnostic device in a remote diagnostic imaging site, Human imager operated diagnostic device in the hospital

What is being measured

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

  1. Accuracy in the diagnosis of referral retinal lesions

    Accuracy in the diagnosis of referral retinal lesions using the self-testing diagnosis imaging

    Measured: 1 week

Secondary outcomes (4)
  1. The agreement between the two modalities

    kappa value to assess the agreement between the two modalities in the diagnosis of referral retinal lesions

    Measured: 1 week

  2. Feasibility of self-testing diagnosis imaging model

    Feasibility is measured by examination completion rate

    Measured: 1 week

  3. Feasibility of self-testing diagnosis imaging model

    Feasibility is measured by interpretable image rate

    Measured: 1 week

  4. Satisfaction of participants as measured by questionnaire

    Satisfaction is measured by a questionnaire between the two modalities

    Measured: 1 week

Questions about this trial

What is this clinical trial studying?

An observational study of Diabetic Retinopathy, run by Zhongshan Ophthalmic Center, Sun Yat-sen University at 1 site in China.

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 1 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 4 Apr 2023. 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 China. 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?

Accuracy in the diagnosis of referral retinal lesions (time frame: 1 week). 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 4 Apr 2023.
