About this study

Official title: Shanghai Eye Disease Prevention and Treatment Center

Objective: to evaluate the efficacy of different concentrations of atropine eye drops in controlling the progression (diopter, axial length) of high myopia in young children, and to compare the compliance, adverse reaction and regression rate of different concentrations of atropine eye drops in myopia control.

Intervention: Group 1 (0.01% atropine group), Group 2 (0.04% atropine group), Group 3 (0.1% atropine group). During the 2-year intervention period after entering the group, each concentration of atropine eye drops were given every night at a fixed time before going to bed, one drop each time, implemented by parents (supervision), and the wechat small program was completed.

What participants receive

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

  • AtropineDrug

    different concentrations (0.01%/0.04%/0.1%) of atropine were administered to high myopic children

What is being measured

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

  1. Changes of spherical equivalent

    Spherical equivalent as measured by cycloplegia autorefraction

    Measured: at least 2 years

Secondary outcomes (5)
  1. Change in axial length

    AL was measured as the distance from the anterior corneal surface to the retinal pigment epithelium (RPE) using IOLMaster or Lenstar

    Measured: at least 2 years

  2. Best corrected vision acuity (BCVA)

    BCVA were measured at 4 meters by trained optometrists using the Early Treatment Diabetic Retinopathy Study (ETDRS) logMAR chart

    Measured: at least 2 years

  3. Intraocular pressure (IOP)

    Intraocular pressure (IOP) is measured using a non-contact tonometer, with the average of three consecutive measurements taken.

    Measured: at least 2 years

  4. Pupil size

    Photopic and mesopic pupil diameters were measured using a handheld device (VIP-300, NeurOptics) after a 2-minute light adaptation and a 5-minute dark adaptation, respectively

    Measured: at least 2 years

  5. Accommodative function

    Positive/negative relative accommodation (PRA/NRA) were performed at a distance of 40 cm

    Measured: at least 2 years

Questions about this trial

What is this clinical trial studying?

A study testing Atropine in people with High Myopia, run by Shanghai Eye Disease Prevention and Treatment Center at 3 sites in China.

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 6 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 12 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in China. 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?

Changes of spherical equivalent (time frame: at least 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04699357, which also lists 1 linked publication.

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 12 Mar 2026.
