Caterpillar setae-induced acute anterior uveitis: a case report.

Abstract

To report uveitis secondary to ocular penetration of caterpillar hairs (setae). Case report. A documented attack of acute anterior uveitis was caused by initially overlooked penetration of caterpillar setae. A 66-year-old man presenting with unilateral hypertensive keratouveitis was treated with antiherpes simplex medication (along with local anti-inflammatory and cycloplegic agents) after anterior chamber paracentesis and serologic testing. Laboratory testing was negative. Resolution occurred after 5 days, and corneal clearing showed a predescemetic caterpillar seta. Patient history taken in an anterior uveitis setting should include gardening habits and searching for possible exposure to insects or arachnids.
