Optha- Foreign Body
harry206 - 05-15-09 09:07
A 35-year-old Caucasian male with no significant past medical history presents to the emergency department complaining of severe pain in his left eye. Earlier that afternoon he was working on his boat when he dropped a heavy metal crate onto the boat’s wooden deck. Immediately after he dropped the crate, he felt one or more small foreign objects enter his left eye. The eye began to water profusely and he was unable to open it sufficiently to examine the cornea. He states that he does not wear contact lenses. Physical examination of the left eye reveals edema of the upper eyelid, conjunctival hyperemia, diffuse corneal inflammation, and corneal abrasion. After a topical anesthetic was applied to the injured eye, irrigation with saline was successful in removing all debris. What organism is most commonly cultured from corneal foreign bodies?
