This review examines the impact of moderate to severe dry eye disease on da
ily life and medical-resource utilization. The results suggest that current
treatment paradigms can lead to unacceptable costs in both quality of life
and progressive use of healthcare resources. Evidence linking this disease
to T-cell-mediated inflammatory processes lays the foundation for understa
nding the clinical benefits of topical cyclosporine, an immunomodulatory an
d anti-inflammatory agent.
