slit-lamp

A low-power, binocular microscope with an intense light source, used to examine the internal structures of the front part of the eye and, by means of special eye contact lenses, the VITREOUS BODY and the RETINA.

slit-lamp 

Instrument producing a bright focal source of light with a slit of variable width and height. It may be used to examine the tissues of the anterior segment of the eye in conjunction with a microscope (usually binocular) of variable magnification. To examine the internal structures of the eye including the retina an auxiliary lens is required. Many such lenses exist, some which do not make contact with the eye (e.g. Hruby lens, Volk lens) and others which come in contact with the eye, usually like a scleral type of lens (e.g. Goldmann lens, Thorpe four mirror fundus lens, Wilson three mirror fundus lens). A slit-lamp is essential in contact lens practice. This instrument is also commonly called a biomicroscope (Fig. S9). See fundus biomicroscopy; gonioscope; illumination; Shaffer and Schwartz van Herick method; Smith's method; slit-lamp microscope; endothelial polymegethism.

Comparison of Smartphone Ophthalmoscopy with Slit-lamp Biomicroscopy for Grading Diabetic Retinopathy(PO282) was released at AAO 2014, the 118th annual meeting of the American Academy of Ophthalmology which is in session October 17-21 at McCormick Place in Chicago.
At the initial visit, all patients had a complete ophthalmic examination, including slit-lamp biomicroscopy.
Safety is being assessed via vital signs, laboratory tests, slit-lamp biomicroscopy, dilated fungus examination, fundus photography, serial ECGs and elicited and observed adverse events.
The practical sessions included slit-lamp demonstrations by Professor Steve Parrish and Dr Anna Kwartz, and a scenario-based dispensing workshop sponsored by Carl Zeiss Vision which proved particularly popular.
