Multimodal imaging in the diagnosis and management of ophthalmia nodosa.

ABSTRACT

Purpose: Ophthalmia nodosa (ON) is a rare but important disease describing ocular inflammation caused by injury from insect hairs ("setae"). Type V ON occurs when there is vitreoretinal involvement. Treatment with systemic steroids are first-line, but vitrectomy is indicated in resistant cases. The purpose of this study was to illustrate how multimodal imaging can facilitate diagnosis and management of ON. Observations This is a single retrospective case report of a patient who presented to Bascom Palmer Eye Institute with Type V ON. Multimodal imaging in a patient with Type V ON was illustrated. A moth seta was localized to the anterior vitreous cavity. Intraocular inflammation responded to 2 weeks of high-dose oral prednisone. Conclusions and Importance Multimodal imaging may guide diagnosis and management of ON by documenting baseline features of ON and facilitating comparison at follow up visits. This allows for safe non-surgical management of Type V ON. Long-term follow up would be necessary to determine whether subsequent surgical intervention was needed in this case.
