A history of eye pain, corneal clouding, or decreased vision suggests a possible tumor. Juvenile xanthogranuloma (JXG) may be associated with small orange-brown papules on the head or face. Iris JXG lesions may bleed, and the resultant hyphema may cause ocular pain.ExaminationWithout a slit lamp, evaluation of iris lesions may be difficult, particularly in a noncooperative toddler. Some lesions may be visible with a penlight. Benign iris cysts are often seen best by examining the pupil margin when evaluating the red reflex with a direct ophthalmoscope.
