    A, Normal open angle. Gonioscopic photograph shows trace pigmentation of the posterior trabecular meshwork and normal insertion of the iris into a narrow ciliary body band. The Goldmann lens was used. B, Normal open angle. This gonioscopic view using the Goldmann lens shows mild pigmentation of the posterior trabecular meshwork. A wide ciliary body band with posterior insertion of the iris can also be seen. C, Narrow angle. This gonioscopic view using the Zeiss lens without indentation shows pigment in the inferior angle but poor visualization of angle anatomy. D, Narrow angle. Gonioscopy with a Zeiss lens with indentation shows peripheral anterior synechiae in the posterior trabecular meshwork. Pigment deposits on the Schwalbe line can also be seen. This is the same angle as shown in part C.
