Doc here.
Iridodialysis (no relation to regular dialysis) is a localized separation or tearing away of the iris from its attachment (to the ciliary body, not visible from outside)
When it is detached, being a membrane, it basically flops around. Looks weird. Mostly after trauma to head like boxing injury or after eye surgery.
Not life-threatening by itself. But don't leave it alone. It can progress. If it's indeed you, op, go see ophthalmologist.
