Contusions of the eyeball result in varying degrees of trauma to the ocular structures, depending on the amount and direction of transmitted force. The resultant complications are recognized as hyphemia, or hemorrhage into the anterior chamber, rupture of the iris sphincter and traumatic mydriasis, various stages of traumatic cataract with or without dislocation of the lens, vitreous hemorrhage and ruptures of the retina and choroid. When no rupture of the cornea or sclera occurs, the traumatic hyphemia may result in the consecutive secondary complications of bloodstaining of the cornea, atrophy of the iris, secondary glaucoma and glaucomatous optic atrophy with anterior staphyloma, occasionally necessitating enucleation. Very rarely sympathetic ophthalmia has followed the latter chain of events. The ophthalmologist is helpless in treating the first group of traumatic complications, since the damage has already been done before the patient is ever seen for treatment. However, most of the complications of the
