Quantitation of Tear Lysozyme Levels in Dry-Eye Disorders

Vincent P. Deluise, Khalid F. Tabbara

Research output: Contribution to journalArticlepeer-review


A simple, rapid, reproducible method of quantifying tear lysozyme levels with a dual-channel spectrophotometer was used to compare normal subjects and those with dry-eye syndrome. The method was sensitive (80%) and specific (85%) and had a predictive value of a positive result of 83%. One patient with clinical manifestations of dry-eye syndrome and paradoxically elevated levels of tear lysozyme was found to have underlying sarcoidosis.
