1923A. Duane Fuchs's Text-Bk. Ophthalmol. xviii. 372 If the observer, standing to one side, holds the ophthalmoscopic mirror almost at right angles to the patient's line of sight, he can see deposits and adhesions in the angle of the anterior chamber, which ordinarily are invisible because hidden by the limbus (Salzmann). Such an examination is called gonioscopy. 1925M. U. Troncoso in Amer. Jrnl. Ophthal.
