Scoring criteria used for evaluation of corneal lesion size and corneal neovascularization.

SLE scoring system for corneal lesion size
	SLE score 0.0–0.5	SLE score 0.6–0.9	SLE score 1.0–1.9	SLE score 2.0–2.9	SLE score 3.0–3.5	SLE score 3.6–4.0
Corneal Lesion Scoring	Normal or nonspecific corneal lesions, random superficial lesion	Punctate ulcerations	One or more dendritic ulcerations; Dendritic lesions involving <50% of cornea	Dendritic lesions involving >50% of the cornea	Geographic ulcerations of trophic erosion involving less than 50% of the cornea	Geographic ulcerations of trophic erosion involving more than 50% of the cornea

Grading of Corneal Neovascularization
	Grade 0	Grade 1	Grade 2	Grade 3
Corneal Neovascularization	No blood vessels visible	<25% of the corneal surface covered with developing network of blood vessels	26–75% of the corneal surface covered with developing network of blood vessels	>75% of the corneal surface with developed network of blood vessels
