title: New Ultrasound Biomicroscopy Iris Findings in Juvenile Xanthogranuloma.
abstract: We report a case of juvenile xanthogranuloma in a 12-month-old girl presenting with heterochromia, hyphema, and elevated intraocular pressure. This case demonstrates new ultrasound biomicroscopy iris findings of a generalized bumpy iris contour, suggesting diffuse heterogeneous involvement. This imaging finding has not been previously described. Untreated, iris juvenile xanthogranuloma may lead to corneal blood staining, glaucoma, and amblyopia. An understanding of the full range of ultrasound features of juvenile xanthogranuloma expands our appreciation for the clinical findings in this condition.
