Correlation between the thickness of the AM and age (a), fibroblasts (b), CD68⁺ cells (c), CD86⁺ cells (d), and CD206⁺ cells (e) cells. The correlation between these were significant (ρ = 0.332, p = 0.004; ρ = 0.336, p = 0.003; ρ = 0.274, p = 0.018; ρ = 0.271, p = 0.020; ρ = 0.312, p = 0.007), respectively. AM: arachnoid membrane
