Slit Lamp Exam

Overview & Description | Preparation & Expectations | Results and Values

In this procedure, the healthcare provider examines the structures in the front of the eye with a magnifying device and special light called a slit lamp. This helps show any abnormalities of the cornea, sclera, lens, conjunctiva, or eyelids.

Who is a candidate for the test?

This is part of a routine eye examination.

How is the test performed?

The person sits in a chair with the chin on a chin-rest. An arm with the slit lamp and a microscope swings in front of the face. The slit lamp and microscope give the healthcare provider a magnified view of the structures at the front of the eye. A drop of fluorescent dye may be placed in the eye to make it easier to spot defects in the cornea, the transparent covering of the iris and pupil. The dye is washed away quickly by the person's tears.
