A Single-center, Retrospective Study to Evaluate the Clinical Performance of Artificial Intelligence Medical Assisted Diagnostic Software (VeriSee DR) for Screening of Diabetic Retinopathy in Patients With Diabetes Mellitus

Study Overview
=================
Brief Summary
-----------------
This study is to evaluate the clinical performance of VeriSee DR for DR screening from color fundus photography images in patients with diabetes mellitus. The sensitivity and specificity of VeriSee DR's automated image analysis for screening the diabetes retinopathy will be determined.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Sensitivity | To evaluate the clinical performance of VeriSee DR by determining the sensitivity. Sensitivity = 100% x TP/(TP+FN) | 2 months | 
| Specificity | To evaluate the clinical performance of VeriSee DR by determining the specificity. Specificity = 100% x TN/(TN+FP) | 2 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Positive Predictive Values (PPV) | To evaluate the clinical performance of VeriSee DR by determining the positive predictive values (PPV). Positive predictive value (PPV) =100% x TP/(TP+FP) | 2 months | 
| Negative Predictive Values (NPV) | To evaluate the clinical performance of VeriSee DR by determining the negative predictive values (NPV). Negative predictive value (NPV) = 100% x TN/(FN+TN) | 2 months | 
| Percentage of Participant Images With Insufficient Quality as Judged by VeriSee DR | To determine the percentage of subjects' images with insufficient quality as judged by VeriSee DR. The percentage of subjects who have the images with insufficient quality as determined by VeriSee DR will be presented. | 2 months |
