Fig. 1. Immunnohistochemistries for CD4⁺ and CD8⁺ lymphocytes. CD4 positive cells infiltrated mostly in peribulbar area. CD8⁺ cells infiltrated mostly in intrabulbar area. The severer histopathologic gradings were associated with the denser infiltrations of mononuclear cell (A~C: CD4, ×100), (D~F, CD8, ×100).
