| exposure keratitis | Inflammation of the cornea resulting from irritation caused by inability to close the eyelids. Synonym: lagophthalmic keratitis. (05 Mar 2000) |
| keratitis | <ophthalmology> Inflammation of the cornea. Compare: keratoconjunctivitis. (18 Nov 1997) |
| keratitis, dendritic | A form of herpetic keratitis characterised by the formation of small vesicles which break down and coalesce to form recurring dendritic ulcers, characteristically irregular, linear, branching, and ending in knoblike extremities. (12 Dec 1998) |
| keratitis disciformis | Large disk-shaped infiltration of the central or paracentral corneal stroma. This lesion is deep and nonsuppurative and is seen in virus infections, particularly herpetic. Synonym: keratitis disciformis. (05 Mar 2000) |
| keratitis filamentosa | A condition characterised by the formation of epithelial filaments of varying size and length on the corneal surface. Synonym: keratitis filamentosa. (05 Mar 2000) |
| keratitis, herpetic | A superficial, epithelial herpes virus hominis infection of the cornea, characterised by the presence of small vesicles which may break down and coalesce to form dendritic ulcers (keratitis, dendritic). (12 Dec 1998) |
| keratitis linearis migrans | A deep, linear corneal opacity stretching from limbus to limbus; associated with congenital syphilis. (05 Mar 2000) |
| keratitis nummularis | Coin-shaped or round, discrete, grayish areas 0.5 to 1.5 mm in diameter scattered throughout the various layers of the cornea. Synonym: Dimmer's keratitis. (05 Mar 2000) |
| keratitis profunda | An inflammation of the posterior corneal stroma. Synonym: diffuse deep keratitis. (05 Mar 2000) |
| keratitis sicca | Drying and inflammation of the conjunctiva as a result of insufficient lacrimal secretion. When found in association with xerostomia and polyarthritis, it is called sjogren's syndrome. (12 Dec 1998) |

| absorption band | The range of wavelengths or frequencies in the electromagnetic spectrum where radiant energy is absorbed by passage through a gaseous, liquid, or dissolved substance; it is exploited for analytical purposes in colourimetry or spectrophotometry, and is usually described in terms of the wavelength where maximum absorbance occurs (i.e., lambdamax).
