NCT06821399

Brief Summary

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.

Outcome Measures

Primary Outcomes (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.

    Conduct examinations at enrollment and twelve months after enrollment.

Secondary Outcomes (5)

  • Metabolomics analysis

    at enrollment

  • Triglycerides

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

  • Glycated Hemoglobin

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

  • Insulin levels

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

  • Total Cholesterol

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

Study Arms (4)

DR High-Risk Population Cohort

An 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.

Diagnostic Test: Fundus ExaminationDiagnostic Test: Metabolomics analysis

Diabetic Retinopathy Early-Stage Population Cohort

Seeking specific metabolites that can reflect diabetic retinopathy and its severity in early - onset and late - onset type 2 diabetes mellitus (T2DM).

Diagnostic Test: Fundus ExaminationDiagnostic Test: Metabolomics analysis

Moderate-Stage Diabetic Retinopathy (DR) Population Cohort

Exploring 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.

Diagnostic Test: Fundus ExaminationDiagnostic Test: Metabolomics analysis

Advanced-Stage Diabetic Retinopathy (DR) Population Cohort

The 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.
