Immunoassay of tear immunoglobulin A and lysozyme in acute bacterial conjunctivitis

The tear lysozyme and immunoglobulin A [I g A] content in 50 normal subjects and in 100 patients with different acute bacterial conjunctivitis were determined by a single radial immunodiffusion technque. Tear lysozyme level in normal subjects was 1.30+0.64 mg/ml. The mean tearlysozme level in acute bacterial conjunctivitis 1.28+0.35 which is not significantly different from those in the normal controls. Immunoglobulin A level in tear of normal subjects was 24.6+15 mg/100 ml. The mean tear immunoglobulin A level in acute bacterial conjunctivitis was 34.1+18 mg/100 ml. Which is sinificantly higher than normal
