Role of Scheimpflug imaging in the diagnosis and management of keratitis caused by caterpillar seta

ABSTRACT

A 16-year-old boy presented with a history of an accidental hit to the left eye by a butterfly [Lepidoptera]. One seta fragment was found to be embedded into the cornea and inflammation secondary to penetration of caterpillar seta was seen around the seta fragment. Scheimpflug imaging was performed in the area showing caterpillar seta. Corneal infiltration was imaged as a hyper-reflective area. Lesion dimensions were measured with calipers. Scheimpflug imaging is a potential tool for localization of corneal lesions, monitoring the progress of the injury and evaluating the treatment response objectively
