ERIO GREEN

Lissamine green is used for diagnosis of corneal damage and to quantify tear production. These strips work by staining the cornea blue upon instillation, resulting in a “speckling” of the cornea. This speckling marks any corneal ulcerations as well as dry patches from any muco-deficient or damaged corneal cells. A white or blue light may be used on sthe slit lamp during detection. Lissamine green possesses a therapeutic advantage in that it does not sting the eye like Rose Bengal; however, as interpretation of lissamine green results requires broader experience than that of Rose Bengal and fluorescein, fluorescein staining is considered to be a more reliable indicator of corneal damage.
