Table 2 XV-based functional grading of CEE-System
From: A novel single-cell level evaluation method for corneal endothelial cell function
Grade | CD (cells/mm2) | XV | <XVn_th (%) | å XVd_th (%) | Annotation |
|---|---|---|---|---|---|
Ⅰ | > 2000 | 0.2~0.28 | >71.4% | 0 | Normal function |
Ⅱ | 2000-1000 | 0.28~0.43 | 71.4~11.4% | 0~0.3% | Below normal physiological conditions |
Ⅲ | 1000-500 | 0.43~1.40 | <11.4% | 0.3~7.2% | Impaired corneal endothelial function, clinically insignificant |
Ⅳ | 500-300 | 1.40~2.67 | 0 | 7.2~41.2% | Inner eye surgery may lead to bullous corneal lesions |
Ⅴ | <300 | > 2.67 | 0 | > 41.2% | Has already developed or is highly susceptible to bullous corneal lesions |
