Iris dialysis and retinal dialysis caused by coin throwing.

A 13-year old boy was hit in the right eye by a coin that was thrown at him. He presented to the accident and emergency (A&E) department with an oblique corneal abrasion, microscopic hyphaema, iris-ciliary body dialysis, commotio retinae with retinal haemorrhages and a large retinal dialysis. The limited amount of available data in the medical literature suggests that eye injuries as a result of coin throwing are serious and should always be referred to an ophthalmologist for evaluation.
