Ophthalmic dirofilariasis.

Dirofilaria tenuis infection involving the eye and ocular adnexae is rare. We report a patient from Florida with a subconjunctival worm which was surgically removed and identified as immature D. tenuis. Ophthalmic involvement of this organism is found most commonly in Florida and the southeastern United States. Raccoons are a natural host and mosquitoes a natural vector for D. tenuis.
