Retained posterior segment indocyanine green dye after phacoemulsification

We describe a patient who had indocyanine green (ICG) staining of the anterior capsule for phacoemulsification of a traumatic cataract. Intraoperatively, the ICG extended into the posterior segment. Postoperatively, the patient developed ICG toxicity to the retina and had a vitrectomy to remove the ICG. We believe ICG extended into the vitreous through an area of zonular dehiscence.
