The cornea is the front part of the eye. It is usually very smooth and clear but sometimes ulcers can form . An ulcer is a disintegration of the surface layer of cells which leads to an open sore that heals slowly.
Also, chronic infection at the site can really delay healing and lead to infection and inflammation of other parts of the eye ..such as the iris.
The underlying cause must be treated if it is known eg remove foreign objects caught behind the eyelids.
Sterile lubrications applied to the surface of the eye may help reduce frictional damage
Antibiotics are used to treat or prevent infection.
Collagenase inhibitors (eg acetylcysteine) and antiprotease drugs (eg polysulfated glycosaminoglycans) have been used .
Unfortunately, some ulcers do not heal well and further treatment may be needed to stimulate healing. Commonly used methods include :
If the organism pseudomonas is present treatment is an emergency with antibiotic gentamicin and an anticollagenase drug (eg acetylcystein)
