Grade I injuries may have corneal epithelial damage but a clear cornea, no corneal opacity, and no limbal ischemia.

These injuries generally carry a good prognosis for recovery. Irrigation and topical care are frequently the only required interventions.

Grade II through IV injuries will have corneal haze or opacity and limbal ischemia.

These injuries will have a guarded prognosis and will require more intensive treatment. Grading is determined by the most severe finding. For example, an eye with a clear cornea but showing limbal ischemia would be classified as grade II or higher.

Goals

Initiate eye irrigation as quickly as possible to reduce damage to the eye, treat the injury to prevent or reduce scarring and visual loss.
