About this study

This study aims to integrate clinical indicators and features of fundus images, combined with metabolomics, to construct an early warning model for diabetic retinopathy (DR) in type 2 diabetes. By combining clinical indicators with metabolomics, the investigators aim to establish a precise DR typing model based on the age of diabetes onset (early-onset diabetes, late-onset diabetes) and based on the coexistence with two types of diabetic macrovascular complications. A multidisciplinary collaboration will be conducted for comprehensive management of DR to control the progression of moderate-stage DR. Cloud-based patient rooms combined with continuous glucose monitoring (CGM) will further explore the role of integrated diabetes retinopathy ward management models in the management of patients undergoing diabetes retinopathy surgery, pioneering a new model for the management of advanced DR.

What participants receive

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

  • Fundus ExaminationDiagnostic test

    Performing fundus photography on patients to assess the progression of diabetic retinopathy (DR).

  • Metabolomics analysisDiagnostic test

    Conduct metabolomics testing at enrollment.

Study groups in NCT06821399
Study groupRoleWhat they receive
DR High-Risk Population CohortAn annual follow - up fundus examination is conducted. Metabolic differences are analyzed between the population with progressed diabetic retinopathy (DR) and those without progression. A predictive model for early warning of DR in type 2 diabetes is constructed to forecast the onset of DR one year later.
Receives: Diagnostic Test: Fundus Examination; Diagnostic Test: Metabolomics analysis
Diabetic Retinopathy Early-Stage Population CohortSeeking specific metabolites that can reflect diabetic retinopathy and its severity in early - onset and late - onset type 2 diabetes mellitus (T2DM).
Receives: Diagnostic Test: Fundus Examination; Diagnostic Test: Metabolomics analysis
Moderate-Stage Diabetic Retinopathy (DR) Population CohortExploring a multidisciplinary model of chronic disease management for patients in the middle stage of diabetic retinopathy (DR), with both the endocrinology department and the ophthalmology department jointly developing standardized standard operating procedures for systemic and ocular examinations of metabolic diseases.
Receives: Diagnostic Test: Fundus Examination; Diagnostic Test: Metabolomics analysis
Advanced-Stage Diabetic Retinopathy (DR) Population CohortThe establishment of an integrated ward for diabetic eye diseases. For patients with severe diabetic eye diseases who urgently need ophthalmic surgery in the short term but have poor blood glucose control, the ophthalmology and endocrinology departments jointly manage and treat the patients. Endocrinologists adjust the blood glucose - lowering treatment plan. After the blood glucose stabilizes, ophthalmic surgery is performed. Continuous glucose monitoring is used to closely observe blood glucose fluctuations during the hospital stay, including intraoperative blood glucose. After the surgery, both ophthalmologists and endocrinologists jointly follow up with the patients.
Receives: Diagnostic Test: Fundus Examination; Diagnostic Test: Metabolomics analysis

What is being measured

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

  1. Fundus examination

    Assess the severity of diabetic retinopathy (DR), and group accordingly. The high - risk DR cohort and the early - stage DR cohort have a fundus examination once a year; the mid - stage DR cohort has a fundus examination every six months; the late - stage DR cohort has a fundus examination every three months.

    Measured: Conduct examinations at enrollment and twelve months after enrollment.

Secondary outcomes (5)
  1. Metabolomics analysis

    By metabolomics, we aim to establish a precise DR typing model based on the age of diabetes onset (early-onset diabetes, late-onset diabetes) and based on the coexistence with two types of diabetic macrovascular complications so that we can better prevent and treat diabetic retinopathy.

    Measured: at enrollment

  2. Triglycerides

    Measured: Conduct examinations at enrollment, six months after enrollment, and twelve months after enrollment.

  3. Glycated Hemoglobin

    Measured: Conduct examinations at enrollment, six months after enrollment, and twelve months after enrollment.

  4. Insulin levels

    Measured: Conduct examinations at enrollment, six months after enrollment, and twelve months after enrollment.

  5. Total Cholesterol

    Measured: Conduct examinations at enrollment, six months after enrollment, and twelve months after enrollment.

Questions about this trial

What is this clinical trial studying?

An observational study of Diabetes and Diabetic Retinopathy, run by Yufan Wang 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 2 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: looking for participants now, as of the sponsor's last update on 23 Apr 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?

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?

Contact Liping Gu Liping Gu (86-13564720656, guliping1980@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Fundus examination (time frame: Conduct examinations at enrollment and twelve months after enrollment.). 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 23 Apr 2026.
