Figure 5. Topography of immunohistochemical labeling of ICAM-1 in choriocapillaris

Colorimetric detection of ICAM-1 (A,C) and endogenous alkaline phosphatase visualized by the NBT/BCIP alkaline phosphatase reaction product (B,D) in the macular (A,B) and peripheral (C,D) choroid in tissue sections containing both regions. An increase in labeling of the macular choriocapillaris (CC) was frequently noted in human eyes (14 out of 20 eyes). Scale bar represents 50 μm.
