ABSTRACT

Slit lamp biomicrography reproduces, through images, what an ophthalmologist might find under examination with a slit lamp biomicroscope. The main difference between the device used by an ophthalmologist and that used by an ophthalmic imager is that the imager's device has some way to capture images. Slit lamps are used by ophthalmologists to examine the anterior segment and adnexa of the eye, as well as limited areas in the posterior segment such as the vitreous and portions of the retina. Slit lamps can create a variety of lighting approaches on the eye to best illuminate certain features. All slit lamps, whether for examination or photography, always contain two main components: an optical microscope and an illumination system. The main difference between an examination slit lamp and a photographic slit lamp is the addition of three main elements: a beam splitter, an attached camera and an additional light source, usually an electronic flash, to provide enough light for exposure.
