Interferon-gamma (IFN-γ) status in sections of human iris, as shown by AEC staining.

<p>Results for IFN-γ were negative in all examined iris sections. Scale bar, 50 μm</p

Interleukin (IL)-2, IL-6, interferon-gamma (IFN-γ), and transforming growth factor-beta (TGF-β) in the irises of primary open-angle glaucoma (POAG) and chronic angle-closure glaucoma (CACG) patients and control subjects.

<p>Differences between groups were analyzed by ANOVA Least Significant Difference test. <i>P</i> value ≤ 0.05 was considered statistically significant. Mean concentrations of IL-2, IFN-γ, and TGF-β showed an upward trend in the iris of POAG and CACG patients. A downward trend of IL-6 was observed in the irises of POAG and CACG patients.</p

Transforming growth factor-beta (TGF-β) status in sections of human iris, as shown by AEC staining.

<p>TGF-β results were negative in all examined iris sections. Scale bar, 50 μm</p

Interleukin (IL)-2 status in sections of human iris, as shown by AEC staining.

<p>IL-2 results were negative in the control subjects and positive in the primary open-angle glaucoma (POAG) and chronic angle-closure glaucoma (CACG) patients. Positive staining was localized to the anterior surface of the iris, the blood vessel wall in the stroma, the cytoplasm of some cells, and the posterior pigment epithelium. Scale bar, 50 μm</p
