ögonundersökningsverktyg

An ögonundersökningsverktyg, or ophthalmic instrument, is a tool used by eye care professionals to examine the eye. These instruments allow for detailed observation of the various structures of the eye, aiding in the diagnosis and monitoring of ocular conditions.

Common ögonundersökningsverktyg include the ophthalmoscope, which illuminates the interior of the eye, enabling examination of the retina, optic nerve, and blood vessels. The slit lamp is another crucial instrument, a biomicroscope that provides a magnified, three-dimensional view of the eye's anterior structures, such as the cornea, iris, and lens. Tonometers are used to measure intraocular pressure, a key indicator for conditions like glaucoma. Furthermore, visual acuity charts, like the Snellen chart, are simple yet essential tools for assessing a patient's sharpness of vision. Other instruments may include refractors to determine refractive error, gonioscopes to examine the angle of the anterior chamber, and fundus cameras for digital imaging of the retina. The appropriate use of these tools is fundamental to comprehensive eye care.
