Hyperosmolarity is a major cause of cell damage over time and can result in apoptosis of corneal and conjunctival cells. Determining if a patient has hyperosmolarity is critical allowing us to offer therapies to correct the problem. Reducing and regulating osmolarity is important in preventing potential long-term tissue compromise. Treatment leading to decreasing tear osmolarity can improve the patient's quality of life by stabilizing vision and, in many cases, simply allowing patients to return to normal activities.
