Corneal abrasion consists in the loss of the outer layer of the cornea, called epithelium. It becomes noticeable after traumas (e.g. a finger in the eye) or corneal dystrophy.
Corneal dystrophy is often linked to the patient’s family medical history. Usually, the Bownman membrane is ruined and this makes the epithelium less stable and prone to detach itself even in case of very light traumas (e.g. opening the eyes at night). The most noticeable symptom is a very strong pain that is more bearable when the eye is kept close.
Treatment consists in bandaging the affected eye and rest. The epithelium grows back again in a couple of days. An eye examinations is fundamental to avoid the risk of infections.
People that are experiencing recurring or relapsed corneal abrasion, can undergo specific treatments, such as:
Corneal abrasion is a very painful condition, but it usually heals by itself in a few days. Cornea can suffer abrasions while putting on make up, after traumas or because of contact lenses, or again repeatedly in case of cornea dystrophy.
It is necessary to use immediately antibiotic eye drops to prevent corneal infecrions; keeping the eye closed usually gives relief and speeds up the healing process. The best thing to do is get in touch with an ophthalmologist that can suggest the best treatment.
