Naimer SA, Mumcuoglu KY - Dermatol Pract Concept (2014)

Bottom Line: Ophthalmomyiasis in humans caused by the larvae of the sheep nasal botfly (Oestrus ovis) and is a rare phenomenon in Israel.After the physical removal of the larvae with the help of a cotton swab applicator under a slit lamp examination and the topical use of antibiotics, the clinical symptoms improved within 1-2 days.Undoubtedly the dermatoscope played a crucial role leading to the definitive diagnosis and immediate therapeutic intervention.

ABSTRACT
Ophthalmomyiasis in humans caused by the larvae of the sheep nasal botfly (Oestrus ovis) and is a rare phenomenon in Israel. We describe the utilization of the dermatoscope as a diagnostic tool for the facilitation of early diagnosis of conjunctivitis due to the infestation of the eyes by the sheep nasal botfly in two patients. After the physical removal of the larvae with the help of a cotton swab applicator under a slit lamp examination and the topical use of antibiotics, the clinical symptoms improved within 1-2 days. Undoubtedly the dermatoscope played a crucial role leading to the definitive diagnosis and immediate therapeutic intervention.

Mentions: A 17-year- old teenager arrived at the clinic after spending the prior night and day hiking the Hevron mountains. He recalled that previous day he had the sensation of suddenly being struck in the face by a fly. His left eye gradually became more and more irritated and he felt something moving around inside his eye. The findings were similar to those in the patient in Case 1, except that in this patient, the time lapse between the infestation and diagnosis led to substantial accumulation of purulent secretion which hindered clear visualization of the complete conjunctival surface. Upon examination with the dermatoscope, the smartphone screen displayed a number of larvae wriggling over the cornea and bulbar surface trying to evade discovery (Figure 2). At the Kedumim Family Health Center, 15 larvae were manually removed with the tip of a cotton wool applicator using a full scale slit lamp. Again an occlusive ocular dressing was left in position after antibiotic ointment application. The following day the patient reported that his symptoms had improved significantly.
