Dry Eye Syndrome is a term that covers numerous diseases that affect the tear film, the surface of the eye, and surrounding tissue. Vision may or may not be affected. Although each of these diseases is unique and distinct, they can also precipitate or cause other related diseases. Often the diseases co-exist, cause the same symptoms, or cause additional symptoms that can exacerbate each other. For example, evaporative dry eye can cause or contribute to aqueous tear deficiency and vice versa. These are some of the reasons why Dry Eye is so difficult to treat.
