Second is ultrasound biomicroscopy of anterior chamber showing iris-related hyperecho heterogenous lesion abutting the corneal endothelium. Third is slit lamp photo 2 years after treatment showing significant resolution of the iris lesion. Fourth is slit lamp photo 7 years after treatment, showing that iris cavernous hemangioma regressed.
