Abstract

Insect hairs are a well-known cause of dermal irritation and sometimes can be an occupational hazard for planters.1 These hairs can migrate into the eye and occasionally elicit ocular manifestations, ie, ophthalmia nodosa. This ocular injury is sometimes caused by tarantula hairs.2 It is rare, though, for these hairs to induce such an endophthalmitis that vitrectomy is required to eliminate the inflammation.3 We report 2 cases of endophthalmitis caused by caterpillar setae. Surgical removal of the setae during vitrectomy was imperative to terminate the inflammation in the first case.

Report of Cases. 

Case 1.  On September 3, 1993, a 45-year-old man visited our clinic complaining of irritation in the left eye since he had spent some time gardening. Slitlamp examination revealed that several caterpillar setae were embedded in the cornea (Figure 1, left), subconjunctival space, and ocular angle. Endophthalmitis with hypopyon soon developed (Figure 1, right). Removal
