ABSTRACT
A healthy 57-year-old man present to outpatient ophthalmological services in southwestern Connecticut with a 16-month history of unilateral periorbital pain, photophobia, and progressively decreasing visual acuity in his left eye. Prior extensive work-up for uveitis in his home state of Mississippi had yielded no etiology for his symptoms, and empiric therapy with glucocorticoid eye drops had not halted their decline. Fundoscopic examination demonstrated total combined retinal detachment of the left eye. Extensive repeat serological and immunological screening was positive for Toxocara immunoglobulin-G, consistent with a diagnosis of ocular toxocariasis, and the patient completed a course of albendazole with stabilization of symptoms. Despite toxocara being endemic to the United States, diagnoses of ocular toxocariasis are extremely uncommon, with the majority of cases occurring in young children. This unusual case of ocular toxocariasis in a healthy adult serves to illustrate that significant, irreversible morbidity can result from lack of both clinician and public awareness of this parasitic infection.
