Dear Colleagues:

It is our pleasure to present to you part 3 in a series of monographs on diagnostic and treatment algorithms for ocular surface disease states. First issued in 2008, the series has been updated for 2011 with the latest research. Part 1 focused on ocular allergy and part 2 on conjunctivitis.

This monograph will comprehensively review new and existing information as it relates to the understanding and management of dry eye. It also offers a consensus on the most effective ways to address and manage this condition. We hope you find the information contained here to be as valuable as we intended it to be and that it serves you well as a resource in practice.

This series has been made possible because of the generous support of Bausch + Lomb. Next up in the 2011 series is part 4, which will cover the topic of keratitis. — The Authors
