A Case and Review of Ophthalmomyiasis Caused by Oestrus ovis in the Central Valley of California, United States

“…Although ophthalmomyiasis externa is uncommon in North America, prevalence can change with the exposure to host livestock or its manure. Early diagnosis and management of ophthalmomyiasis externa is important in preventing complications, such as ophthalmomyiasis interna, 10,11 or auricular, 23 nasal, 9,23,24 pharyngeal, 23,25 or laryngeal 23 myiasis. There is no known systemic treatment for this condition, only mechanical removal.…”
