Abstract

Most dermatologists find some type of magnifying system useful in their practice. Over a period of 15 years, I evaluated magnifiers ranging from simple low-power, single-lens systems to a Zeiss operating microscope. This report reviews the various types of magnifiers available for examining the skin's surface and describes their optical characteristics. For the dermatologist a binocular loupe with magnification of 3X to 4X appears to be the most useful diagnostic magnifying device. Higher magnifications failed to yield additional clinically useful detail. Lower-power binocular magnifiers of 2X to 2.5X, although useful as a surgical aid, provided less-than-optimal magnification for diagnostic purposes. The ideal magnifier for each practitioner will depend on subjective needs, as well as optical characteristics. Currently available magnifiers are described and evaluated.
