From: Teleophthalmology and retina: a review of current tools, pathways and services
Validation category | Capability |
---|---|
1 | Separation of patients into two categories: 1) No or minimal DR (ETDRS level ≤ 20) 2) More than minimal DR (ETDRS level > 20) |
2 | Separation of patients into two categories: 1) Non-sight-threatening DR 2) Sight-threatening DR (diabetic macular edema (DME), severe non-proliferative DR (ETDRS level ≥ 53), or proliferative DR (ETDRS level ≥ 61) |
3 | Identification of ETDRS defined levels of non-proliferative DR (mild, moderate, severe), proliferative DR (early, high-risk), and DME with sufficient accuracy to determine follow-up and treatment strategies at a level equivalent to dilated clinical retinal examination |
4 | Ability to match or exceed the ability of ETDRS photos to identify and determine severity of DR and DME |
