About this study

Official title: Constructing Children's Eye Data Sharing Platform in Multiple Centers and Multiple Disciplines

Use cohort research to analyze and compare eyes of healthy children and children with systemic diseases. Understand and analyze the incidence, characteristics and influencing factors of children's ocular surface diseases. Establish a multi-center children's eye data sharing platform to provide basic data support for the diagnosis and treatment of children's ocular surface diseases.

Use cohort research to analyze and compare eyes of healthy children and children with systemic diseases. Understand and analyze the incidence, characteristics and influencing factors of children's ocular surface diseases. Establish a multi-center children's eye data sharing platform to provide basic data support for the diagnosis and treatment of children's ocular surface diseases.

All participants will be recruited from Zhongshan Ophthalmic Center, Sun Yat-sen University and Affiliated Foshan Maternity \& Child Healthcare Hospital, Southern Medical University. Only children with written informed consent from their parents can participate in this study.

Participants will be excluded for (1) age>18; (2) previous use of orthokeratology lenses or low-concentration atropine; (3) allergy to compound tropicamide eye drop; (4) any history of ocular surgery.

All participants will undergo optometry and biometric measurements by a trained team. The axial length (AL), central corneal thickness (CCT), anterior corneal radii of curvature, anterior chamber depth (ACD), lens thickness (LT), the curvature power of the central flat meridian (K1) and the central steep meridian (K2), the ocular surface and fundus will be measured. All measurements will be taken in room light condition (1000 lux).

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 3 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

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 Yingting Zhu (13580585671, ytzhu16@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

change of the non-invasive tear break-up time (time frame: baseline, 24th months). 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?

On the ClinicalTrials.gov record for NCT05247099, 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 18 Feb 2022.
