Abstract-Text Purpose:
To report a case of sheep gadfly infestation as an unusual cause of marked conjunctival inflammation which may present in returning travellers.

Methods:
Review of patient chart and literature

Results:
A 73 year old female recently returned from a recreational visit to Turkey presented to our clinic with ocular discomfort and redness of her left eye. Examination confirmed a marked unilateral conjunctivitis with otherwise normal ocular examination findings attributable to infestation with a single live larva of type Oestrus ovis, also known as sheep gadfly. Removal of the organism and topical combination treatment with steroids and antibiotics resulted in rapid resolution of clinical signs and symptoms.
Oestrus ovis infestation may present as unilateral conjunctival inflammation yet can be a challenging diagnosis to make. Careful medical and travel history taking, coupled with awareness of the epidemiology and life cycle of the sheep gadfly are key to making the diagnosis, which may not be obvious on cursory clinical examination, even with everted conjunctivae. The clinician should also be aware of associated lacrimal/naso-lacrimal manifestations and complications of this infestation.

Conclusion:
Conjunctival inflammation with a history of recent traveling in regions to which Oestrus ovis is endemic should alert the ophthalmologist to the possibility of gadfly larvae, a careful search for which should be undertaken.
