We examined 50 patients to determine whether differences exist between the initial clinical signs and symptoms associated with infected vs sterile corneal infiltrates. A detailed history regarding contact lens use and ocular symptoms was taken, after which a careful slit-lamp examination was performed. The ocular findings were correlated with the results of corneal cultures. Increased pain (P less than .001), discharge (P less than .0001), epithelial staining (P less than .0001), and anterior chamber reaction (P less than .0001) were associated with infected ulcers. Sterile infiltrates were usually smaller; multiple or arcuate; and without significant pain, epithelial staining, or anterior chamber reaction.

D003315 Cornea The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous CORNEAL EPITHELIUM; BOWMAN MEMBRANE; CORNEAL STROMA; DESCEMET MEMBRANE; and mesenchymal CORNEAL ENDOTHELIUM. It serves as the first refracting medium of the eye. It is structurally continuous with the SCLERA, avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the TRIGEMINAL NERVE via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses.
