I wish to reiterate an observation which I made a number of years ago, when I called attention to the occurrence of a subconjunctival hemorrhage in the presence of a penetrating foreign body as evidence of double perforation of the globe.1 This occurs when the foreign body enters the cornea obliquely and leaves the eye through the sclera, at some distance from the point of entrance, to embed itself under the overlying conjunctiva. I stated :

When the foreign body penetrates the eye by way of the cornea the passage is through an avascular stratum, and consequently there is no subconjunctival bleeding. The foreign body flies at such a high rate of speed that penetration usually occurs with but little mechanical shock to the globe as a whole; there are therefore no hemorrhages under the conjunctiva such as are found in cases of contusion. The bleeding that takes place is
