Abstract

BACKGROUND: Bird spiders, known in the US as tarantulas, are large hairy spiders that have become increasingly popular as pets in the Western world. We present a patient with a red irritated eye from exposure to the hairs of a spider of the Theraphosidae family, and review the literature. PATIENT AND METHODS: We report on a 28-year old patient who was referred to our clinic with a red irritated eye following playing with a Chilean rose-haired bird spider (known in the US as tarantula). In addition, we reviewed the literature concerning similar cases using the Medline database and cited literature in the retrieved articles. RESULTS: Our patient displayed theraphosidae (tarantula) hairs in the cornea of the right eye and developed a uveitis and a retinochoroiditis with associated vitritis. Treatment with topical corticosteroids resulted in an improvement of signs and symptoms, although the improvement was slow and incomplete. The disease process consists of a granulomatous reaction to the spider hairs. Hairs of Theraphosidae spiders (tarantulas) may cause inflammation at all levels of the eye, from the conjunctiva to retina. We were able to identify 14 cases of Ophthalmia nodosa secondary to the exposure to the tarantula hairs in the literature. Therapy includes removal of the offending hairs when possible and topical treatment with steroids. CONCLUSION: Although the large hairy bird spiders (tarantulas) are considered harmless pets, ophthalmia nodosa is a potential danger when handling them. Ophthalmia nodosa has an unknown prognosis and may be difficult to manage.
