Abstract
- PURPOSE
To analyze the changes of tear composition in chronic blepharitis patients. METHODS: Tear samples were collected from 30 eyes of 29 patients diagnosed as chronic blepharitis by slit-lamp examination, and from 30 eyes of 30 normal volunteers. Chronic blepharitis group was subdivided into untreated group (10 eyes; tear sampling before the initiation of treatment) and treated group (20 eyes; tear sampling after the initiation of treatment). Tear pH, concentration of ions (Na+, K+, Cl-, Ca2+), total protein concentration and tear protein fraction (TPF) were measured. Statistical analysis was done by using Mann-Whitney U test and Kruscal-Wallis test, and p-value
