The changing times in dry eye research.

The last 2 years in dry eye research have been memorable; in fact, they have been a culmination of over a decade of effort by a growing group of passionate and steadfast individuals in the clinical and research dry eye community. Some of the fruits of these efforts are reflected in this special dry eye issue of Optometry and Vision Science (OVS), and represent several of the initiatives and recommendations found in the recently published report(s) of the International Dry Eye Work Shop (DEWS). The recent growth of our knowledge in the field of dry eye can be assessed by comparing the DEWS reports to what is arguably the most read and cited article in the field of dry eye research, the 1995 NEI/ Industry report on clinical trials in dry eye. The NEI/Industry report is 12 pages in length, including references. At the time it was published, it represented the significant effort put forth by researchers in defining the disease, classifying the condition, and defining future research directions. The current DEWS report (an entire journal issue, 125 pages in length) demonstrates the significant advances in the field over time, and like its predecessor, provides a dry eye research road map for the next generation of tear film and ocular surface clinicians and researchers.
