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