—Dr. Smith stated in a recent article Archives (89:484, 1973) that blowout fractures invariably result from objects of greater diameter than the orbit.In the last three years, I have repaired orbital blowout fractures on two teenagers who gave a rather clear cut history of being struck in the eye by a finger. One had an associated conjunctival laceration, and the other had a corneal abrasion, traumatic iritis, and iridoplegia. Following surgery both had no residual muscle abnormality and no anophthalmos.These cases seem to indicate that an orbital blowout fracture can be caused by an object smaller than the diameter of the orbit without causing rupture of the globe.
