To the Editor We would like to provide follow-up information on our Clinical Challenge titled “Anterior Chamber Angiostrongyliasis.”1 The Parasitic Diseases Branch of the Centers for Disease Control and Prevention reviewed the published photographs as well as original digital images and expressed concern at our final diagnosis of an anterior chamber worm. Specifically, in the photographs, they believed there were no specific morphologic features that could definitively identify the foreign object as a worm (eg, internal structures such as gut or reproductive tubes, body wall composed of cuticle and muscles, oral or anal opening). While clinically the object appeared wormlike, it was found to be in poor condition after removal, perhaps due to long-standing nonviability in the eye. Unfortunately, the specimen has since been disposed of and no further investigations are possible.
