Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To develop an artificial intelligence (AI) model to predict DR progression based on a prospective cohort database.With use of an innovative AI model and a validated machine learning algorithm, based on multimodal vascular and neuro imaging of the eye, the progression of diabetic microangiopathy especially the DR could successfully be predictse and fundamentally facilitate diabetes management.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

To develop an artificial intelligence (AI) model to predict DR progression based on a prospective cohort database.This study will first conduct a prospective single-center cohort, which will enroll 250 type 2 diabetes mellitus patients with non-proliferative diabetic retinopathy (NPDR). The follow-up time points will be 3 months, 6 months, 1 year, 2 years, and 3 years after enrollment or reaching the endpoint (any condition that needs retinal photocoagulation, anti-vascular endothelial growth factor injections, and pars plana vitrectomy). The study will collect both patient clinical characteristics and multi-model eye imaging. With use of an innovative AI model and a validated machine learning algorithm, based on multimodal vascular and neuro imaging of the eye, the progression of diabetic microangiopathy especially the DR could successfully be predictse and fundamentally facilitate diabetes management.

Exclusion Criteria

* (1) conjunctivitis, keratitis, blepharitis, episcleritis, scleritis, uveitis, severe dry eye disease, using anti-glaucoma eyedrops, or any condition causing conjunctival congestion or ciliary congestion, (2) pterygium, wearing contact lens in the past week, ocular surface burn, conjunctival tumors, or any condition causing significant conjunctival vascular deformities, (3) previously undergone intraocular surgeries involving manipulation of the conjunctiva, or corneal refractive surgery, (4) history of hematological disorder, dysthyroidism, rheumatic disorder, malignant tumor, (5) refractive media opacity resulting in poor visualization of fundus photographs, (6) difficulty in maintaining fixation or comprehension, making it challenging to cooperate with the examination, (7) difficulty in completing follow-up visits in 3 years.
