Figure 1. Histology of OCP conjunctiva. OCP conjunctiva was infiltrated with immune cells, including lymphocytes, plasma cells and leukocytes (A), whereas healthy conjunctiva was free of immune cells (B). A linear direct immunofluorescence labeling (green) of autoantibodies in the conjunctival basal membrane was observed in all OCP samples (insert A). No immunostaining was observed in control samples (insert B).
