Corneal epithelial erosion

Corneal epithelial erosion is a clinical symptom caused by recurrent corneal erosion disease. Repetitive corneal erosion occurs after the corneal epithelium is damaged (corneal rupture), and the adhesion between the regenerated epithelium and the basement membrane and the cladding layer is not tight enough. As a result, once the eyes are opened after the eyes are closed, it may cause The damaged healing cornea is torn apart again, causing the symptoms of corneal peeling (eye tingling, redness, fear of light, tears, eyes that cannot be opened, etc.) appear again and again, and at the same time, bacteria can be used Machine, and cause corneal infections and ulcers. In addition, some people do not have a history of trauma, but the symptoms of recurrent corneal erosion may be due to the presence of lesions in the basement membrane of the corneal epithelium, and the reason needs to be further clarified. Superficial punctate keratopathy is a general term for three types of lesions of the corneal epithelium, namely punctate epithelial keratitis, punctate epithelial erosions, and punctate subepithalial infiltrates), they often coexist, but the severity and extent of the lesions are slightly different and different.
