Figure 5. Representative photomicrographs of double immunostaining of CD68 and TNF-α or interleukin-1β (IL-1 β) in the normal retina and the retina on day 2, with and without treatment of oxidized adenosine triphosphate (OxATP) at 30 µM just after intraocular pressure (IOP) elevation. A: TNF- α, B: IL-1 β. Immunoreactivities of tumor necrosis factor-α (TNF-α) and IL-1β were upregulated in the ganglion cell layer (GCL) and inner plexiform layer (IPL) cells on day 2 after IOP elevation; they were subsequently suppressed by treatment with OxATP. Bar=100 µm.
