Quantitation of tear lysozyme levels in dry-eye disorders

V P deLuise et al. Arch Ophthalmol. 1983 Apr.

Abstract

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.
