Clinical Evaluation of VeriSee AMD in Screening for Age-Related Macular Degeneration
A Single-center, Retrospective Study to Evaluate the Clinical Performance of Artificial Intelligence Medical Assisted Diagnostic Software (VeriSee AMD) for Screening of Age-Related Macular Degeneration
Study Overview
Status
Detailed Description
This is a retrospective, single-center, observational study to assess the clinical performance of VeriSee AMD in screening for potential age-related macular degeneration (AMD).
Potential subjects with images of color fundus photography will be selected for eligibility, and then the ophthalmologist further confirms the images with legible quality. Three independent ophthalmologists (or evaluators) having more than 6 years of experience in retina will evaluate AMD from the color fundus photography images with different sequences of images independently. These three evaluators are different from the ophthalmologist who is responsible for deciding subject's eligibility. The evaluators determine the severity of AMD based on the four-level scale which is the AMD Severity Scale stated in Age-Related Eye Disease Study (AREDS) Report No. 6. Before the study, the training section is necessary to ensure the consensus of the AMD severity grading among three evaluators. The severity determined by the majority of the grade the three evaluators gave is considered the gold/reference standard in this study. Therefore, level 1 and level 2 are classified as non-mtl3AMD, while level 3 and advanced AMD (level 4) are classified as mtl3AMD. The clinical performance displayed as sensitivity and specificity will be determined by comparing the AMD results between VeriSee AMD and the gold standard.
VeriSee AMD is intended to screen AMD from the images taken by color fundus photography, which can assist the physicians to assess whether further examination for retinopathy by the ophthalmologist is needed. The screening result of AMD will be non-mtl3AMD or mtl3AMD for the physicians' reference and does not intend to diagnose AMD, detect concomitant diseases, or treat AMD.
