The cornea may be stained with dye to better find ulcers, scratches or other injuries. Topometry may be applied to test for intraocular pressure. Tear production may be measured with a Schirmer Test. This includes checking for blinking reflexes, object following ability, and proper light sensitivity. Often, the function of the pupils will be evaluated using Visual Pathway Testing.
