This patient presents to you after sustaining ocular trauma a few months ago. You see the white cataract, likely intumescent, so you decide to use trypan blue to stain the anterior lens capsule. Then, after washing out the trypan with balanced salt solution, more trypan blue dye leaks out in this pattern. Why? What does that mean? Where did this trypan blue die come from? What do you think that means? What happens next?
