Introduction  The value of gonioscopy in the management of traumatic lesions of the anterior chamber angle has been stressed by Troncoso,1 Thorpe,2 and Scheie.3 It is invaluable in recognizing peripheral anterior synechiae, occult hemorrages, exudates, small iridodialyses, peripheral iridoschises, cyclodialyses, and minute foreign bodies lodged in the recesses of the filtration angle.In the past several years, the author has made a routine practice of gonioscoping all eyes which had received blunt trauma. It is the purpose of this paper to describe the gonioscopic appearance of a characteristic defect of the anterior chamber angle noted during these observations, and to report the clinical course of a relatively unknown type of monocular glaucoma with which it may or may not be associated.

Contusion Angle Deformity  The deformity is characterized by an increased depth of the anterior chamber which is often measurable by slit-lamp examination (Fig. 1). Gonioscopy reveals
