![]() In addition, if the cornea becomes excessively dry, it may become more brittle and easily damaged by movement across the surface. Damage may result when the lenses are removed, rather than when the lens is still in contact with the eye. Injuries can also be incurred by "hard" or "soft" contact lenses that have been left in too long. ![]() A foreign body in the eye may also cause a scratch if the eye is rubbed. Common causes include being poked by a finger, walking into a tree branch, and wearing old contact lenses. Occasionally the healed epithelium may be poorly adherent to the underlying basement membrane in which case it may detach at intervals giving rise to recurrent corneal erosions.Ĭorneal abrasions are generally a result of trauma to the surface of the eye. It is important that any foreign body be identified and removed, especially if containing iron as rusting will occur. Complications Ĭomplications are the exception rather than the rule from simple corneal abrasions. Crusty buildup from excess tears may also be present. The vision may be blurred, both from any swelling of the cornea and from excess tears. Signs include epithelial defects and edema, and often redness of the eye. Signs and symptoms of corneal abrasion include pain, trouble with bright lights, a foreign-body sensation, excessive squinting, and reflex production of tears. Complications may occur in up to 8% of people. Complications can include bacterial keratitis, corneal ulcer, and iritis. The typical age group affected is those in their 20s and 30s. Males are more often affected than females. Ībout 3 per 1,000 people are affected a year in the United States. Evidence does not support the usefulness of eye patching for those with simple abrasions. Paracetamol (acetaminophen), NSAIDs, and eye drops such as cyclopentolate that paralyse the pupil can help with pain. In those who wear contact lenses a fluoroquinolone antibiotic is often recommended. Treatment is typically with antibiotic ointment. Prevention includes the use of eye protection. More significant injuries like a corneal ulcer, globe rupture, recurrent erosion syndrome, and a foreign body within the eye should be ruled out. Diagnosis is often by slit lamp examination after fluorescein dye has been applied. Most cases are due to minor trauma to the eye such as that which can occur with contact lens use or from fingernails. Most people recover completely within three days. Symptoms include pain, redness, light sensitivity, and a feeling like a foreign body is in the eye. A corneal abrasion after staining with fluorescein, it is the green mark on the eye.Ĭorneal abrasion is a scratch to the surface of the cornea of the eye.
