Trial summary

This study aims to collect a baseline dataset of MHRC retinal scans that will be used for the pre-training of deep learning models from the hyperspectral retinal image phenotypic features that may form the basis for multiple future classification applications. Read more about this study

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 18 years and older
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: Adults ages 18 years and older who have undergone pupil dilation and are not contraindicated for mydriatic imaging with a fundus camera. Ideally, the study population will be reflective of the adult population with the following estimates for demographics. Gender* 49% Male 51% Female Age* 45% 18-44 years old 55% 44+ years old Ocular Health ǂ 70% Normal ocular health 30% Eye symptoms * based on 2021 Canada census data ǂ based on CNIB Fast Facts about Vision Loss

Who may be able to join

  • Adults 18 years and older who will undergo mydriasis (pupil dilation) as part of their eye clinic visit.

Who cannot join

  • Pupil dilation contraindicated (due to a 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 MHRC.
  • Refractive error outside the range of -15 D to +15 D.
  • Deficient visual fixation (inability to fixate for at least 2 s)
  • Inability of obtaining at least 3 images of satisfactory quality with the MHRC per the Optina Diagnostics quality index software and /or per the eye specialists' evaluation.

About this study

Official title: Retinal Deep PhenotypingTM by a Novel Mydriatic Hyperspectral Retinal Camera (MHRC) and Analysis by Deep Learning

This study aims to collect a baseline dataset of MHRC retinal scans that will be used for the pre-training of deep learning models from the hyperspectral retinal image phenotypic features that may form the basis for multiple future classification applications. A sub-set of the images will also be analyzed by eye specialists to determine if visual inspection of the images could provide useful information in their practice.

As an exploratory study, there are no endpoints per se, however the following sub-objective will be evaluated for determining the success of this study:

  • Collection and characterization of MHRC retinal images from at least 2000 participants that score at least 80 on the real-time Quality Index (included in the MHRC software).
  • Development of at least one (1) DL model of the retina. Models may be used for the development of novel classifier tests and potential use in a clinical setting.
  • At least 5% of participants shall have an MHRC retinal image reviewed by an eye specialist (Optometrist or Ophthalmologist) to assess the image quality and potential clinical usefulness.
Read the detailed description

This is an exploratory, observational, cross-sectional, multi-site study designed to collect a baseline dataset of MHRC retinal image scans for use in Deep Learning models and to determine the feasibility of visual inspection of the images for use in Optometry and/or Ophthalmology clinical practice. Subjects will be recruited from eye clinics where patients will undergo mydriasis (pupil dilation) as part of their clinical visit. Eligible participants will be provided information about the study and delegated site personnel will assist with the Informed Consent process. If a participant provides their Informed Consent, they will be enrolled in the study and undergo a single retinal imaging session with the Optina MHRC device, on one or both eyes.

The MHRC retinal images will be transferred to a Picture Archiving and Communication System (PACS) for archiving and later evaluation. Additional information about the Study Participant will be captured in an Electronic Data Capture (EDC) system, including age, date of birth, gender, race/ethnicity, and color of their iris.

Images will be transferred to Optina for further digital analysis, including pre-processing (normalization, registration, and segmentation), feature extraction, and inclusion in Deep Learning models.

A subset (at least 5%) of the MHRC retinal scans will undergo visual inspection by an eye specialist (Ophthalmologist or Optometrist) to determine their quality and utility for inclusion in clinical practice.

Questions about this trial

What is this clinical trial studying?

An observational study of Healthy, run by Optina Diagnostics Inc. at 2 sites 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 1 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: finished, as of the sponsor's last update on 13 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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?

At least one (1) pre-trained DL model from hyperspectral retinal images. (time frame: 12 months). 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 13 Dec 2024.
