Richard Lindstrom, MD, of Minnesota Eye Consultants, highlights the importance of osmolarity testing in patients with suspected dry eye disease. Studies demonstrate that as many as 50% of patients with dry eye disease are asymptomatic, so having an objective measure of potential dry eye disease will help identify patients who are in need of therapy.
Dr. Lindstrom said that incorporating the TearLab osmolarity test has changed his practice in a number of ways, including allowing the more accurate diagnosis of dry eye disease. This has been critical, he said, in treating the ocular surface more aggressively, especially in surgical candidates. The objective measures of osmolarity provide patients with an identifiable marker of ocular surface health, which may help improve compliance with therapy if they understand how dry eye disease could affect surgical outcomes. Finally, osmolarity testing can provide insight into the outcomes of a given therapy, thus allowing surgeons greater opportunity to maximize the health of the ocular surface.
