Slit Lamp
A Slit Lamp (pronunciation: /slɪt læmp/) is a piece of equipment used primarily by ophthalmologists and optometrists for examining the eyes. It is an essential tool in the diagnosis and monitoring of various eye diseases and conditions.
Etymology
The term "Slit Lamp" is derived from its design. The device uses a high-intensity light source that can be focused to shine a thin sheet of light into the eye. The term "slit" refers to this thin sheet of light, and "lamp" refers to the light source.
Function
The Slit Lamp is used to examine the anterior and posterior segments of the human eye, which includes the eyelid, sclera, conjunctiva, iris, natural crystalline lens, and the cornea. The binocular slit-lamp examination provides a stereoscopic magnified view of the eye structures in detail, enabling anatomical diagnoses to be made for a variety of eye conditions.
