Figure 4. Lymphocytes and macrophages scattered throughout the pterygium. Immunohistochemistry using anti-leukocyte common antigen (LCA), anti-CD3, and anti-CD68 antibodies showed the characteristic distribution of inflammatory cells. A-C: Tissue image was obtained from case 4. D-F: Tissue image was obtained from case 8. LCA and CD3 staining showed a similar clustered distribution, suggesting most LCA-expressing cells are T cells. CD68-expressing cells are smaller in population and have an evenly scattered distribution.
