Grade | Area of corneal opacity | Density of corneal opacity | Surface regularity |
|---|---|---|---|
1 | 1–25% | slightly opacity of the cornea, relatively clear pupil and iris | slight irregularity of the lesion surface |
2 | 26–50% | opacity of the corneal superficial layer, visible pupil and iris through the lesion | rough and lesion surface with some swelling |
3 | 51–75% | uneven opacity of the whole corneal layer | Significant swelling, crater or serious descemetocele formation |
4 | 76–100% | even and dense opacity | Perforation or descemetocele |
