Subepithelial scars

This 54 year-old non-contact lens user developed two corneal ulcers in her left eye one year ago. The culture was negative and the ulcers responded to topical antibiotics. At a recent visit, she complained of recurrent foreign body sensation in the left eye. The fluorescein stain shows tear film instability over the scar. She responded to topical artificial tear.


Healed ulcers with subepithelial scars.


Superior subepithelial scar with ferritin deposits (faint yellowish epithelial staining).


Inferior subepithelial scar with ferritin deposits.


The fluorescein stain shows early breaking up of tear film over the scars.
