Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 50 years and older

Study population: Men and women 50 years and older who can undergo pupil dilation for both eyes and are not contraindicated for mydriatic imaging with a fundus camera.

Who may be able to join

  • Male and female adults aged 50 years and older with vision in both eyes.

  • Ability to give informed consent.
  • Individuals with both eyes meet the eligibility criteria for retinal imaging.

Who cannot join

  • Pupil dilation contraindicated (due to pathology, or presence of 3 quadrants with Van Herick grading of 0 or 1 without iridotomy).
  • Inadequate pupil dilatation (< 6mm diameter) preventing uniform illumination of the retina with the Optina 4CTM camera.
  • Diagnosis of glaucoma or signs of glaucoma (excavation ratio ≥0.7).
  • Signs of vascular occlusion or retinopathy (microaneurysm, exudate, hemorrhage, or edema) within a diameter of 10 mm from the mid-point between the optic nerve head and the macula.
  • Presence of drusen and/or age-related macular degeneration (AREDS 9-step scale
  • ≥4 - cumulative drusen area diameter ≥ 250 µm, pigmentary changes and cumulative drusen area diameter ≥ 63 µm or pigmentary changes and cumulative geographic atrophy area diameter ≥ 354 µm).
Show all 15Show fewer
  • Nuclear sclerosis > 2 (LOCS II four-point grading system) or presence of central cortical or central posterior subcapsular cataract.
  • Deficient visual fixation (inability to fixate for at least 2 s).
  • Refractive error outside the range of -15 D to +15 D.
  • Corneal or media opacities (e.g., Weiss ring) affecting retinal imaging on a cumulative area > 1 disc area within a diameter of 10 mm from the mid-point between the optic nerve head and the macula (i.e., the area of interest for the Optina 4CTM imaging)
  • Scar, atrophy, naevus, tumor, epiretinal membrane or retinal pucker with a cumulative area > 1 disc area within a diameter of 10 mm from the mid-point between the optic nerve head and the macula.
  • Papilledema and/or optic disc swelling.
  • Macular anomaly (e.g., macular hole, dystrophy, degeneration).
  • Inability to obtain up to 5 images or a minimum of 3 images of satisfactory quality with the Optina 4CTM per the Optina Diagnostics quality index software and /or per the eye specialists' evaluation. This exclusion criterion also applies if participants are unable to provide the required number of images during the second visit as well.
  • Currently taking or has previously taken cerebral amyloid modifying medication.

About this study

Official title: Analytic Validation of the Optina Retinal Deep Phenotyping.TM (RDP) Platform

This is an observational study designed to assess the reliability and consistency of the Optina awAIrTM CAS Test for detecting phenotypic changes in the retina that are associated with beta-amyloid status (positive or negative). The purpose of this study is to ensure that the retinal image capture process is consistent and under control, regardless of the operator or the time of measurement. The study will include enough repeated measurements on different systems, by three operators, and at different times to demonstrate.

Read the detailed description

The purpose of this study is to assess the reliability of the Optina Retinal Deep Phenotyping.TM(RDP) platform. The RDP Platform is comprised of the Optina-4CTM retinal camera and its Optina-4C ConnectTM software, as well as the Optina awAIrTM-CAS Test (also called CAS Test) for detecting phenotypic changes in the retina that are associated with cerebral beta-amyloid status (positive or negative). This study will quantify points of variability in the data input for the CAS Test, including:

  • Left eye vs. right eye (retinal scan)
  • Eye algorithm selection (eye assessment obtained from different eye specialists either an Ophthalmologist or an Optometrist)
  • Hardware variability (Inter-instrument Variability retinal scans obtained from different Optina-4CTM cameras)
  • Inter-operator variability (retinal scans obtained from different Users of the Optina-4CTM camera)
  • Intra-operator variability (retinal scans obtained by the same user on the same Optina-4CTM camera

What participants receive

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

  • Retinal Imaging with Optina4C CameraOther

    The study consists of 2 visits and 8 Imaging sessions:

    The participant will go through four (8) imaging sessions in two visits with the Optina-4CTM cameras to get pictures of your retina. These imaging sessions will be done by three qualified operators who have been trained on the study device by Optina Diagnostics.

What is being measured

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

  1. The reliability of the investigational device's imaging process will be analyzed using agreement of CAS Test results within 95% confidence intervals for the following conditions:

    • Eye to eye variability
    • Eye selection process variability
    • Instrument to instrument variability
    • Inter-Operator variability
    • Intra-Operator variability

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

An observational study of Healthy, run by Optina Diagnostics Inc. 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 15 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 29 Feb 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?

The reliability of the investigational device's imaging process will be analyzed using agreement of CAS Test results within 95% confidence intervals for the following conditions: (time frame: 12 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 29 Feb 2024.
