TNF and glaucoma: The concentrations of IL-6, IL-8, VEGF, and TNF-α have been found to be higher in uveitic glaucoma patients than in POAG patients, and these were correlated with the inflammatory response observed in slit-lamp examination [24], and the profile found in POAG is different of that found in primary open-angle glaucoma, with the latter having increased levels of IL-8 and CXCL9 [10].
