Funduscopic examination utilizing the biomicroscope is extremely valuable in the detection, diagnosis, and management of ocular disease. A variety of lenses are currently available for detailed examination of the posterior vitreous cavity and the retina. This paper discusses the optical principles and the various attributes of four lenses relative to magnification, field of view, clinical application and ease of use.
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.
