About this study

Official title: A Single-center, Retrospective Study to Evaluate the Clinical Performance of Artificial Intelligence Medical Assisted Diagnostic Software (VeriSee AMD) for Screening of Age-Related Macular Degeneration

An observational study is designed to evaluate the clinical performance of VeriSee AMD for potential age-related macular degeneration (AMD) screening from color fundus photography images. The sensitivity and specificity of VeriSee AMD's automated image analysis for screening AMD will be determined through the comparison with the gold standard, which is the judgment of AMD by the ophthalmologists.

Read the detailed description

This is a retrospective, single-center, observational study to assess the clinical performance of VeriSee AMD in screening for potential age-related macular degeneration (AMD).

Potential subjects with images of color fundus photography will be selected for eligibility, and then the ophthalmologist further confirms the images with legible quality. Three independent ophthalmologists (or evaluators) having more than 6 years of experience in retina will evaluate AMD from the color fundus photography images with different sequences of images independently. These three evaluators are different from the ophthalmologist who is responsible for deciding subject's eligibility. The evaluators determine the severity of AMD based on the four-level scale which is the AMD Severity Scale stated in Age-Related Eye Disease Study (AREDS) Report No. 6. Before the study, the training section is necessary to ensure the consensus of the AMD severity grading among three evaluators. The severity determined by the majority of the grade the three evaluators gave is considered the gold/reference standard in this study. Therefore, level 1 and level 2 are classified as non-mtl3AMD, while level 3 and advanced AMD (level 4) are classified as mtl3AMD. The clinical performance displayed as sensitivity and specificity will be determined by comparing the AMD results between VeriSee AMD and the gold standard.

VeriSee AMD is intended to screen AMD from the images taken by color fundus photography, which can assist the physicians to assess whether further examination for retinopathy by the ophthalmologist is needed. The screening result of AMD will be non-mtl3AMD or mtl3AMD for the physicians' reference and does not intend to diagnose AMD, detect concomitant diseases, or treat AMD.

What is being measured

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

  1. Sensitivity

    To evaluate the clinical performance of VeriSee AMD by determining the sensitivity.

    Sensitivity = 100% x TP/(TP+FN)

    Measured: 1 day

  2. Specificity

    To evaluate the clinical performance of VeriSee AMD by determining the Specificity.

    Specificity = 100% x TN/(TN+FP)

    Measured: 1 day

Secondary outcomes (3)
  1. Positive Predictive Values (PPV)

    To evaluate the clinical performance of VeriSee AMD by determining the positive predictive values (PPV).

    Positive predictive value (PPV) =100% x TP/(TP+FP)

    Measured: 1 day

  2. Negative Predictive Values (NPV)

    To evaluate the clinical performance of VeriSee AMD by determining the negative predictive values (NPV).

    Negative predictive value (NPV) = 100% x TN/(FN+TN)

    Measured: 1 day

  3. The Percentage of Subjects' Images With Insufficient Quality as Judged by VeriSee AMD

    The percentage of the images with insufficient quality as determined by VeriSee AMD will be presented.

    Measured: 1 day

Questions about this trial

What is this clinical trial studying?

An observational study of Macular Degeneration, Age Related and Maculopathy, Age Related, run by Acer Medical Inc. at 1 site in Taiwan.

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 5 inclusion and 2 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 22 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 Taiwan. 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?

Yes. Results are posted in the registry (first posted 22 Jan 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Sensitivity (time frame: 1 day). The study lists 2 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 22 Jan 2024.
