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.

Vortex keratopathy was detected by slit-lamp biomicroscopy and IVCM in 7 of the 8 patients who were being treated with oral amiodarone, that is, amiodarone-induced keratopathy.

The average dose of the drugs at the time when the amiodarone-induced keratopathy was first observed was 4178.6[+ or -] 1773.9mg by IVCM and 10,950[+ or -] 12367.7mg by slit-lamp biomicroscopy.

In the 3 patients with Fabry disease, slit-lamp biomicroscopy detected white or yellow powdery corneal deposits arranged in a whorl pattern (Figure 4).

The amiodaron-induced keratopathy was detected as early as 7 days after beginning the amiodarone by IVCM and 14 days by slit-lamp biomicroscopy.

In Vivo Confocal Microscopic Observations of Vortex Keratopathy in Patients with Amiodarone-Induced Keratopathy and Fabry Disease

Slit-lamp examination revealed intact corneal epithelium and silver carbon particles in the inferonasal stroma.

On slit-lamp examination, corneal perforation and fragments of pencil lead were observed at the wound site.

Slit-lamp examination revealed motile larvae in the right palpebral and bulbar conjunctiva.

For this reason, thorough slit-lamp examination should be performed on patients with similar symptoms, especially in areas with high livestock densities.

In summary, external ophthalmomyiasis should be kept in mind in the differential diagnosis of patients presenting with conjunctivitis and a thorough slit-lamp examination including the inner eyelids should be conducted to ensure the diagnosis is not overlooked.

Ophthalmomyiasis externa: a report of three cases

At the first week follow-up examination after the surgery, slit-lamp examination showed stromal striae, but it was impossible to examine the anterior chamber details and diagnose the DMD due to the corneal edema.

Before the introduction of advanced machines, the diagnosis of DMD used to be done by slit-lamp examination with the aid of topical glycerin to dehydrate the edematous cornea.

DMD is reported in this study after an intraocular surgery which was not possible to detect by slit-lamp examination, but it could be shown by ASOCT.
