Diabetic Retinopathy

Diabetic Retinopathy

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...

Medical Imaging

Background:

Endocrine and metabolic diseases pose a growing global health challenge.
Current screening methods can be resource-intensive and time-consuming.
There is a need for scalable and accessible screening solutions.

Purpose of the Study:

To develop Reti-Pioneer, an AI-powered framework for multitask retinal imaging.
To enable efficient, multidisease detection using color fundus photographs.
To assess the framework's performance and generalizability across diverse populations.

Main Methods:

Developed a multitask retinal imaging framework (Reti-Pioneer) integrating quality-aware modules and pre-trained foundation models.
Trained the framework on 107,730 color fundus photographs from community and hospital cohorts.
Validated performance on internal test data and six external cohorts, including resource-limited settings.

Main Results:

Achieved high AUC values for detecting type 2 diabetes mellitus (0.833), gout (0.832), osteoporosis (0.787), hypertension (0.740), hyperlipidemia (0.736), and thyroid disease (0.699).
Demonstrated strong generalization across diverse external cohorts.
Screening time averaged 30.6 ± 6.0 seconds per case, significantly faster than standard workflows.
Clinical pilot for type 2 diabetes mellitus showed AUC of 0.776 and NPV of 0.966, outperforming the Finnish Diabetes Risk Score.

Conclusions:

Reti-Pioneer offers an efficient, low-cost, and translatable screening pathway using retinal imaging (oculomics).
The framework demonstrates potential for early detection and management of multiple endocrine and metabolic diseases.
High acceptance by clinicians and patients suggests clinical utility in primary care settings.
