Abstract

Myiasis is described as infection and infestation by dipterous larvae in organs or different tissues of humans and animals. Ocular myiasis is defined as eye or periorbital tissue infestation by dipterous larvae. Larval stages of the Wohlfahrtia magnifica (Diptera: Sarcophagidae) parasitize many warm-blooded vertebrates resulting in a severe myiasis of mucosal membranes and wound lesions. In the present survey, a rare case of bilateral ocular myiasis due to W. magnifica in an ownerless dog in Iran is described. Physical examinations showed massive larvae over the eyes, unpleasant smell, edema and erythema, ulcers and necrotic tissues. Larvae were removed and were identified under the stereomicroscope with valid morphological keys. Furthermore, the treatment was carried out after removing the larvae, washing, using Oxytetracycline spray and topical permethrin, followed by the antibiotic therapy. The present report suggests that mechanical elimination of the larvae, subsequent washing of the wound with diluted Povidone-iodine, disinfection of the surrounding with permethrin and antibiotic therapy alongside anti-inflammatory drugs are effective in the treatment of orbital myiasis in dogs © 2022 by the authors.
