A slit-lamp examination is often performed by an optometrist during a routine eye exam. The procedure involves the use of an instrument called a slit-lamp, which provides a three-dimensional highly magnified view of the eye. While the exam usually focuses on the structures in the front part of the eye, such as the eyelide, conjunctiva, cornea and iris, it can also be used to examine the optic nerve, vitreous and retina which are located at the back of the eye.

Reasons for a slit-lamp examination

An optometrist will perform a slit-lamp examination to check for any abnormalities of the eye caused by injury, disease or infection.
