Abstract

DURING certain types of surgery, particularly surgery for congenital glaucoma, it is desirable for the surgeon to have a clear direct view of the structures within the angle of the anterior chamber. Unfortunately, gonioscopy during surgery is rendered difficult by a great tendency for air to get under the gonioscopic lens and to obscure the view. Removal of this air while the point of a surgical instrument is in the anterior chamber may be hazardous and difficult. Air more frequently causes trouble during operation than during diagnostic examination of the angle because of differences in the lenses employed and in the amount of manipulation of the eye. In gonioscopic lenses employed for surgery the rim is commonly cut to form a tunnel to give the surgeon access to the limbus of the eye. Such a tunnel facilitates leakage of fluid out and air in. The leakage which takes place through
