The aim is to establish, through tissue and aqueous analysis of patients with pigmentary glaucoma, POAG and normal controls, that markers for anterior chamber autoimmune dysfunction occur in significantly different amounts in patients with these conditions when compared to normal controls. We also will attempt to establish, through proven methodologies of tissue gene expression, that the source of these differences in markers, notably PEDF and IL-18, is from the uveal tissues of the anterior chamber, most importantly the iris and possibly the trabecular meshwork as well.
