LONG COVID – Keratoconjunctivitis sicca

Keratoconjunctivitis sicca (HP:0001097)

Dryness of the eye related to deficiency of the tear film components (aqueous, mucin, or lipid), lid surface abnormalities, or epithelial abnormalities. Keratoconjunctivitis sicca often results in a scratchy or sandy sensation (foreign body sensation) in the eyes, and may also be associated with itching, inability to produce tears, photosensitivity, redness, pain, and difficulty in moving the eyelids.

Synonyms:    Dry eye syndrome, Dry eyes, Keratitis sicca, Xerophthalmia
