We describe the usefulness of intracameral injection of trypan blue to highlight vitreous in the anterior chamber. The technique was used in 3 eyes of 3 patients who had vitreous prolapse in the anterior chamber. Trypan blue 0.06% was injected in the anterior chamber under air to visualize and resect the prolapsed vitreous. Trypan blue stained the clear vitreous and improved visualization for a safe and atraumatic vitrectomy. No complications associated with the dye were found.
