Ophthalmomyiasis with a Singular Subretinal Track

PURPOSE: To report 3 cases of myiasis with a singular subretinal track in the Northeastern part of United States. DESIGN: Noninterventional case series. METHODS: Three patients from Pennsylvania were referred for evaluation of a linear and serpiginous retinal scar. Funduscopic examination and fluorescein angiography were performed to assess the referred retinal lesion. RESULTS: Funduscopic examination showed a singular subretinal track from the superior periphery to either the posterior pole or inferior midperiphery in the study cases. Fluorescein angiography showed exudative retinal detachment in all 3 cases. Laser photocoagulation of the subretinal worm was performed in all reported cases. CONCLUSIONS: Our case series represents a report of singular subretinal tracks presumably caused by the warble fly larva in the Northeastern part of United States. (Am J Ophthalmol 2010;150:731-736.
