Conjunctival myiasis is a condition characterized by the accidental presence of fly larvae in the conjunctiva. We report two ca ses of conjunctival myiasis. The clinical signs were those of a noisy moving foreign body. The diagnosis was based on the detection of fly larvae (maggot) on slit lamp examination. The treatment consisted of extracting the larvae one by one, followed by immediate relief for the patients and then a prescription for antibiotic eye drops. Conjunctival myiasis or external ophthalmomyasis is characterized b y the accidental presence of fly larvae at the level of the conjunctival cul-de-sac. It causes a painful foreign body symptomatology which, if not treated, can progress to internal myiasis.
