Trial summary

Diurnal variations in the thickness of the choroid have been reported in the literature, and, more recently, the role of the choroid has been studied with respect to its role in myopia (near-sightedness) progression. Read more about this study

About this study

Official title: A Sub-Study to Assess the Choroidal Response to Novel Spectacle Lens to Control Myopia Progression (CHERRY)

Diurnal variations in the thickness of the choroid have been reported in the literature, and, more recently, the role of the choroid has been studied with respect to its role in myopia (near-sightedness) progression.

Read the detailed description

Diurnal variations in the thickness of the choroid have been reported in the literature , and, more recently, the role of the choroid has been studied with respect to its role in myopia (near-sightedness) progression. SightGlass Vision, Inc is conducting a multi-site, randomized, controlled, interventional study to confirm the efficacy and safety of spectacle lenses designed to inhibit the progression of myopia by reducing image contrast in peripheral vision. CORE is participating as a clinical site in this three year study which aims to compare changes in ocular length and cycloplegic auto-refraction in children randomised to wear one of either two test or one control spectacle lens designs; the CPRO-1802-001 (Cypress_SG) study. The sponsor is interested in conducting choroidal thickness measurements only at CORE's site by inviting those participants who have already been found eligible for the CPRO-1802-001 study to participate in this parallel study.

Questions about this trial

What is this clinical trial studying?

A study testing Novel spectacle lens design in people with Myopia, Progressive, run by SightGlass Vision, 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 2 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: under way, not looking for participants, as of the sponsor's last update on 5 May 2026. 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?

This study is still under way. Results are not available in the source record yet.

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?

Choroidal thickness (time frame: 3 years). 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 5 May 2026.
