Objective: To present a clinical case of Trichinella spiralis infection where the infectious etiological diagnosis of the systemic disease was reached thanks to early ophthalmological consultation.
Clinical case: A 41-year-old male patient consulted the ophthalmological ward with periorbital edema, subconjunctival hemorrhages, conjunctival chemosis and orbital myositis accompanied by fever, nausea and asthenia for one week. A complete blood count is requested, where eosinophilia is highlighted. Patient was re-interrogated with presumption of pork ingestion. Orbital computed tomography was requested, which showed myositis and after consultation with infectious disease specialists, Trichinella spiralis infection was confirmed by ELISA. Oral treatment is performed with albendazole 400 mg for 7 days and meprednisone 40 mg for 3 days. The patient evolves favorably, complete resolution one month after the onset of symptoms.
Conclusion: Trichinosis is a parasitosis that can affect the ocular structures, and often the ophthalmological consultation is the initial place where this disease must be suspected, confirmed and treated as a team, as happened in the present case, to avoid life-threatening complications.
