Slitlampen

A slitlamp, also known as a biomicroscope or slit lamp microscope, is a specialized ophthalmic instrument used primarily in eye examinations. It combines a microscope with a high-intensity light source to provide magnified, detailed views of the anterior segment of the eye, including the cornea, iris, lens, and anterior chamber. The slitlamp is a fundamental tool in optometry and ophthalmology, enabling clinicians to diagnose and monitor a wide range of ocular conditions.

The device operates by projecting a thin sheet of light (a slit beam) onto the eye, allowing for precise examination of its structures. The clinician can adjust the slit beam’s width, height, and angle to highlight different features, such as corneal layers, fluid dynamics in the anterior chamber, or lens opacities. Additionally, the slitlamp often includes a magnification system and a coaxial illumination system, which enhances visibility and reduces eye strain during prolonged examinations.

Slitlamps are equipped with various attachments, such as a fundus camera for retinal imaging, a gonioscope for angle assessment in glaucoma, and a retroillumination system for evaluating lens clarity. These accessories expand the instrument’s diagnostic capabilities, making it versatile for both routine and specialized eye care.

Regular slitlamp examinations are essential for early detection of conditions like cataracts, glaucoma, corneal ulcers, and diabetic retinopathy. The procedure is non-invasive and typically painless, involving the patient focusing on a target while the clinician observes the eye through the slitlamp’s eyepiece. Proper use of slitlamps requires training, as incorrect technique may lead to inaccurate diagnoses or patient discomfort.

Modern slitlamps often incorporate digital imaging and video recording features, improving documentation and enabling remote consultations. While primarily used in clinical settings, portable slitlamps are also available for fieldwork and telemedicine applications, expanding access to eye care in underserved regions.
