Purpose: To report a case of recurrent external ophthalmomyiasis caused by Lucilia sericata Meigen in a healthy patient.
Case summary: A 72-year-old male, who was diagnosed 7 months earlier with ophthalmomyiasis and obtained
permanent relief by surgical treatment, presented with severe tearing, redness, foreign body sensation, pain in both eyes and aural discomfort in the left ear. On presentation, visual acuity in both eyes was hand movement. On slit lamp examination, total corneal epithelial defect with stromal infiltrations was observed. However, there were no motile organisms in his eyes due to previous removal of maggots at a local clinic. On physical examination, eschar change was observed at the inferomedial area of the left lower eyelid. On otorhinolaryngological examination, several motile organisms with tympanic membrane perforation were observed in the left external acoustic meatus. The patient was treated with topical antibiotic eye drops hourly with systemic antibiotics, and 6 larvae were removed from the external acoustic meatus using otoscopy. Microscopic findings of the removed larvae revealed L. sericata in their third stage of development. After 1 month, corneal epithelial defect and stromal infiltration improved. However, visual acuity in both eyes was 0.1 due to remaining stromal opacities.
Conclusions: In a healthy patient without any predisposing factors, recurrent ophthalmomyiasis accompanied with aural myiasis can develop under poor hygiene conditions.
