How is the Test Performed?
While you are seated in the examining chair, the instrument is placed in front of you and you rest your chin and forehead on a support to keep your head steady. Your eyes are then examined through the biomicroscope. A fine strip of paper that is stained with an orange-colored dye (fluorescein) may be touched to the side of your eye. The dye stains the tear film on the surface of the eye to help with the examination. The dye rinses out of the eye with tears.
After this examination, drops may be placed in your eyes to dilate the pupils. The drops take about 15 to 20 minutes to work. The examination is then repeated, allowing the back of the eye to be examined.
