Recurrent Corneal Erosions
Recurrent Corneal Erosion Syndrome (RCES) is the repeated breakdown of a small area on the cornea. It can occur after a scratch to the eye however some people seem to have an inbuilt tendency for this to happen, due to a weakness in the adhesion of the cells to each other and to the underlying layers.
The typical symptoms include an intense sharp pain, especially when trying to open the eyes on waking. The eyes are often very light sensitive, sore, red and water a lot.
Treatment includes intensive lubrication and barriers creams or bandage contact lenses. For particularly troublesome and non-responsive cases, laser treatment called Photo Therapeutic Keratectomy (PTK) can remove the the defective uppermost layers, thus encouraging a new layer to grow back with stronger cell adhesions.
