External ophthalmomyiasis manifesting with keratouveitis

Purpose To report a case of external ophthalmomyiasis manifesting with keratouveitis. Case report A 77-year-old man, presented with keratouveitis secondary to external ophthalmomyiasis. Slit-lamp examination of the affected eye disclosed subepithelial linear opacities, stromal keratitis, and anterior uveitis. There were also some moving maggots identified as Oestrus ovis larvae. Following removal of the maggots and instillation of tobramycin, the symptoms completely resolved within 2 days and visual acuity improved. Conclusions Although external ophthalmomyiasis usually manifests with ocular surface involvement, this uncommon condition must be considered in the differential diagnosis of keratouveitis, especially in rural areas.
