Background:
- Ophthalmomyiasis externa is a rare condition involving the infestation of the external eye by fly larvae.
- Oestrus ovis, commonly known as the sheep botfly, is a known cause of myiasis in animals and occasionally humans.
Observation:
- A 16-year-old female presented with a foreign-body sensation in her right eye.

- The maggots were successfully removed using a cotton wool-tipped probe.
Findings:
- The patient's symptoms resolved completely following maggot removal.
- This case represents the fifth reported instance of ophthalmomyiasis externa in the southern Africa region.
- The successful treatment underscores the importance of prompt diagnosis and intervention.
Implications:
- This case adds to the limited literature on human ophthalmomyiasis externa caused by Oestrus ovis in southern Africa.
- It highlights the need for increased awareness among healthcare professionals regarding potential zoonotic parasitic infections.
- Early recognition and management are crucial for preventing ocular complications and ensuring favorable outcomes.
