title: Indirect biomicroscopy techniques.
abstract: An improved method of biomicroscopic examination of the ocular fundus has been made possible with the use of a +90 diopter condensing lens. Formation of a superb aerial image provides a magnified, stereoscopic view of the posterior fundus to the equatorial area when used in conjunction with the slit lamp biomicroscope. This non-contact method of evaluating the fundus provides superior optics, improved patient comfort and compliance, and an enhanced field of view compared to other available methods of biomicroscopic funduscopy.
