Why does a SCCED ulcer not heal? The epithelium at the edge of a SCCED ulcer is loose and unable to ‘stick down’ to heal the defect.

Disorders that cause dry eyes (keratitis sicca) can leave the eye without the germ-fighting protection of the tear film and cause or aggravate corneal ulcers. Disorders that affect the eyelid and prevent the eye from closing completely, such as Bell’s palsy, can dry the cornea and make it more vulnerable to ulcers.
