Diabetic Retinopathy
Conditions
Brief summary
This is a prospective clinical study. At the Shaoguan Diabetic Eye Screening Programme, patients ages 30-80 will undergo the two diagnostic models: (1) in a remote diagnostic clinic site, patients undergo a self-testing device that provides both color retinal photography (CRP) and optical coherence tomography (OCT) imaging of nondilated pupils, and receive an online consultation provided by a retinal specialist; (2) on a separate day, patients visit the tertiary hospital, undergo traditional imaging of dilated pupils acquired by a non-expert imager using a traditional CRP imaging device at the point of care, and receive a face-to-face consultation provided by a retinal specialist. Within one week of receiving both diagnostic imaging services, patient preferences are assessed and they decide which diagnostic imaging model is preferred.
Interventions
Full Self-Diagnostic CRP+OCT imaging, followed by online consultation
Human imager operated CRP imaging with dilated pupils, followed by face-to-face consultation
