Some patients are left with varying degrees of scarring after keratitis has healed. Keratitis is an inflammation of the cornea, and the scarring depends on its extent and depth. Lesions that are confined to the corneal epithelium (the cornea is divided into five layers, the corneal epithelium, the anterior elastic lamina, the corneal stroma, the posterior elastic lamina, and the corneal endothelial cells) are non-infectious lesions and generally do not leave a scar. Corneal punctate epithelial lesions can heal on their own and do not affect vision. If deeper keratitis is present, it can leave varying degrees of thin wings, opacities, and whitish patches seriously affecting vision. After the occurrence of keratitis can not be ignored, you should actively go to the ophthalmology examination, according to the examination of the symptomatic treatment, to avoid causing vision damage.
