The cells that make up the top layer of the cornea are called epithelial cells.
These epithelial cells are bound tightly to the cornea by the layer underneath, called the Bowmans layer.
Bowmans layer functions like glue to hold the epithelial cells tightly to the eye.

The Bowman’s layer is made of collagen.
As a result, the epithelial cells come off easily.
Epithelial cells regenerate but they are poorly anchored to the Bowmans layer.
Symptoms
Symptoms of recurrent corneal erosions are similar to those of corneal abrasion.
People tend to recall that they had some pop in of trauma to the eye weeks before.
People who suffer from a recurrent erosion tend to experience its symptoms in the morning upon first waking up.
The eye is usually a little dry from sleeping.
Some people may experience them more during certain times of the year when the weather changes.
Diagnosis
Your eye doctor may diagnose recurrent corneal erosion after taking a careful history.
A recent injury to the eye with a sharp object will usually be revealed.
You may be complaining of episodes of pain and light sensitivity that seem to come and go.
Yourvisual acuitywill be measured.
Your healthcare provider will then instill a special yellow dye called fluorescein.
Treatment
Treatment may consist of calming the eye withcycloplegic eye drops.
Cycloplegic eye drops temporarily paralyze the spasming muscle inside the eye that is creating pain.
Because recurrent erosions are like open wounds, they can become infected.
Antibiotics may be prescribed if you are at risk of developing an infection.
Eye ointments may be prescribed at bedtime.
