epidemic keratoconjunctivitis a highly infectious form, commonly with regional lymph node involvement, occurring in epidemics; an adenovirus has been repeatedly isolated from affected patients.
phlyctenular keratoconjunctivitis a form marked by formation of a small, gray, circumscribed lesion at the corneal limbus.
keratoconjunctivitis sic´ca a condition marked by hyperemia of the conjunctiva, thickening and drying of the corneal epithelium, itching and burning of the eye and, often, reduced visual acuity.

keratoconjunctivitis sicca,
dryness of the cornea caused by a deficiency of tear secretion in which the corneal surface appears dull and rough and the eye feels gritty and irritated. The condition may be associated with erythema multiforme, Sjögren's syndrome, trachoma, and vitamin A deficiency. Methylcellulose artificial tears may give some relief, as can insertion of plugs into the punctae and use of cyclosporine drops.
Dry Eye Syndrome
Dryness of eyes, often due to decreased tear secretion, which occurs in Sjögren syndrome, autoimmune disorders—systemic lupus, rheumatoid arthritis, scleroderma, sarcoidosis—amyloidosis, hypothyroidism, vitamin A deficiency, and in periorbital lymphoproliferative disorders

keratoconjunctivitis

see chronic superficial keratitis.
infectious keratoconjunctivitis
see also infectious bovine kerato conjunctivitis. Caused by Moraxella bovis, Histoplasma capsulatum, Chlamydiae, Mycoplasma spp.
proliferative keratoconjunctivitis
see nodular fasciitis.
keratoconjunctivitis sicca
a condition marked by hyperemia of the conjunctiva, thickening and drying of the corneal epithelium, secondary to quantitative and qualitative deficiencies in the tear film. Deep keratitis and corneal ulceration may occur. Often a tenacious, stringy mucoid discharge accumulates in the conjunctival sac. Called also dry eye.
