Trial summary

We have developed a Multimodal Equipment for Teleophthalmology Assessment (META) device. This novel device is compact, portable and suitable for packaging and express delivery. With this device, there is a potential to implement a new concept of "hospital-at-home" eye care model. Read more about this study

About this study

Official title: Clinical Validation Study for Multimodal Equipment for Teleophthalmology Assessment (META) Device

We have developed a Multimodal Equipment for Teleophthalmology Assessment (META) device. This novel device is compact, portable and suitable for packaging and express delivery. With this device, there is a potential to implement a new concept of "hospital-at-home" eye care model. The present study is designed to validate the META device for future clinical usage and investigation. We will compare the performance of the META device with those provided by commercial devices in terms of image quality of optical coherence tomography (OCT), anterior segment and fundus camera, and evaluate the level of agreement in lesion detection and quantitative measurements between META and other commercial devices (e.g., Heidelberg Spectralis OCT, Haag-Streit BQ900 Slit-lamp imaging, Canon CR-2 fundus imaging, Zeiss IOL Master 500).

Read the detailed description

The META is an innovative and non-invasive examination instrument for a variety of common eye diseases. The integrated multimodality device combines digital slit lamp, fundus camera, OCT, refractometer, optical biometry and visual acuity test (near and distance) that facilitate a comprehensive ophthalmic examination. In the current study, all participants will undergo the measurements provided by the META and by traditional examination modalities (including digital slit lamp, fundus camera, OCT, refractometer, optical biometry and visual acuity test) in a random order. The participants will need to complete several questionnaires to investigate their preference and confidence to receive the META exams in the future.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • METADevice

    The META device is used for a comprehensive ophthalmic examination.

  • Commercial devicesDevice

    Commercial devices (including near and far eye charts, refractometer, optical biometry, slit lamp microscopy, fundus camera and OCT) are used for a comprehensive ophthalmic examination.

Receives: Device: META; Device: Commercial devices

What is being measured

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

  1. Image Quality

    To evaluate the image quality of the META versus commercial devices. These images include slit-lamp anterior-segment images, colour fundus photographs, and OCT scans. The image quality metrics (e.g., position, focus, contrast, etc.) will be identified by masked qualified ophthalmologists independently and scored according to the same grading scheme

    Measured: in the same 1 day

  2. Level of agreement in quantitative measurements provided by META-OCT and by commercial OCT

    OCT images will be captured by META-OCT and by a commercial OCT, and segmented and analyzed with default algorithm to yield quantitative measurements.

    Measured: in the same 1 day

Secondary outcomes (8)
  1. Level of agreement in axial length measurement

    Accuracy of axial length measurement will be captured by META-AL versus by a commercial biometric device.

    Measured: in the same 1 day

  2. Level of agreement in spherical equivalent diopter (SED) and astigmatism vector components (J0 and J45)

    Accuracy of SED and J0 and J45 will be obtained by META-SE versus by a commercial refractor.

    Measured: in the same 1 day

  3. Level of agreement in near and far visual acuity measurements

    Accuracy of near and far visual acuity measurements will be obtained by META-VA versus by reference ETDRS charts.

    Measured: in the same 1 day

  4. Level of agreement in detecting ocular abnormalities.

    Agreement in the detection of ocular abnormalities (e.g., corneal scars, keratic precipitates, lens opacification, macular fluid, or other retinopathy) by META images versus by commercial imaging devices.

    Measured: in the same 1 day

  5. Repeatability in quantitative measurements provided by META-OCT

    OCT images will be captured by META-OCT twice, and the repeatability of quantitative measurements will be assessed.

    Measured: in the same 1 day

  6. Exam success rate

    The exam success rate will be obtained by META versus by commercial devices.

    Measured: in the same 1 day

  7. Time spent on the examinations

    The time spent on the examinations will be obtained by META versus by commercial devices.

    Measured: in the same 1 day

  8. Patient experience

    Investigator-administered questionnaires will be used to investigate participants' preferences and confidence to receive META exams in the future.

    Measured: in the same 1 day

Questions about this trial

What is this clinical trial studying?

An observational study of Eye Diseases, run by Zhongshan Ophthalmic Center, Sun Yat-sen University.

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 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: status not confirmed, as of the sponsor's last update on 4 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.

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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Zitian Liu, Ph.D. (+8618319249014, liuzt25@mail.sysu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Image Quality (time frame: in the same 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 4 Oct 2022.
