Summary
The study analysis the influence of benzalkonium chloride on the density of antigen
presenting Langerhans cells. This is achieved in a double blind randomized study using
in-vivo confocal microscopy to identify and quantify Langerhans cells of the human cornea in
its central and peripheral part. This study design is based on observations with raised
Langerhans cell density after the application of benzalkonium chloride containing eye drops
in glaucoma patients.
