Recurrent corneal erosion is a condition where the corneal surface repeatedly breaks down, causing episodes of sudden eye pain. It often occurs on waking when the eyelid sticks to the cornea.
Causes
It commonly follows a previous corneal abrasion or is associated with underlying corneal dystrophies such as map-dot-fingerprint (epithelial basement membrane) dystrophy. Even minor trauma can trigger further episodes.
- Symptoms include sharp pain, watering, and light sensitivity
- Episodes may last hours to days before settling
- Can recur over months or years
Treatment
Initial treatment uses lubricating ointment, hypertonic drops, and sometimes bandage contact lenses. Persistent cases may benefit from procedures such as epithelial debridement or laser treatment performed in corneal or general ophthalmology clinics.
