Ophthalmomyiasis Externa: A Case Report

Area of Science:

• Ophthalmology
• Parasitology
• Medical Entomology

Background:

• Ophthalmomyiasis is the infestation of the eye by dipteran larvae.
• Oestrus ovis (the sheep bot fly) is a significant global cause of ophthalmomyiasis.
• Understanding the transmission routes is crucial for prevention and treatment.

Observation:

• A case of external ophthalmomyiasis is presented.
• The affected individual was an 18-year-old female residing in an urban center (Istanbul).
• Notably, the patient had no reported history of direct or indirect contact with animals.

Findings:

• The causative agent was identified as Oestrus ovis larvae.
• This presentation underscores the possibility of Oestrus ovis ophthalmomyiasis in individuals without typical animal exposure.
• The urban environment may play a role in the transmission or exposure pathway.

Implications:

• This case expands the known clinical spectrum and potential risk factors for Oestrus ovis ophthalmomyiasis.
• It suggests that ophthalmomyiasis should be considered in the differential diagnosis of ocular conditions, even in non-rural populations.
• Further research into environmental and urban transmission vectors for Oestrus ovis may be warranted.
