Biomikroskoopit

Biomikroskoopit, also known as slit lamp biomicroscopes, are specialized optical instruments used primarily in ophthalmology and optometry. They combine a microscope with a bright, focused light source, allowing for detailed examination of the anterior and posterior structures of the eye. The slit lamp creates a narrow beam of light that illuminates a thin cross-section of the eye, enabling the examiner to visualize structures such as the cornea, iris, lens, and vitreous humor with high magnification and resolution.

The slit lamp biomicroscope typically consists of a microscope eyepiece and a movable slit lamp mounted on a common base. The slit lamp can be adjusted in width, height, and angle, allowing for different illumination techniques. Different magnification levels are available through the microscope, typically ranging from 10x to 40x. This versatility makes it an indispensable tool for diagnosing a wide range of eye conditions, including infections, inflammation, dry eye disease, cataracts, glaucoma, and retinal abnormalities. In addition to visual inspection, biomicroscopy can be combined with other diagnostic techniques like tonometry (measuring intraocular pressure) or gonioscopy (examining the drainage angle of the eye). The technology has evolved over time, with modern biomicroscopes often incorporating digital imaging capabilities for documentation and teleophthalmology.
