THIS PAPER stresses the importance of gonioscopy in the diagnosis of tumors of the posterior chamber of the eye which have not infiltrated into the angle of the anterior chamber or through the iris. The only clue to their presence may be a prominence or bulge of the anterior surface of the iris at its periphery (Fig. 1). The overlying iris stroma, which is usually normal, contributes no information as to the specific nature of the lesion. Gonioscopic examination, therefore, is of extreme value in the differential diagnosis because it may permit direct visualization and accurate identification of the lesion behind the iris. Any tumor arising from the iris or ciliary body might be anticipated, but the commonest is the benign intraepithelial cyst.
No mention has been made in the literature of the fact that the extreme periphery of the posterior chamber of many eyes can be seen by gonioscopic
