Hyperpermeable disc capillaries in glaucoma.

Nine subjects had leakage of fluorescein dye from the capillaries in the glaucomatous discs. Eight subjects had a solitary leakage and one had four points of leakage in the disc. The leakage was ordinarily found in the centre or the temporal margin of the glaucomatous optic disc. No common factors causing dye leakage from the optic disc capillaries appeared to exist in these subjects, except that they had reached a very advanced stage of glaucoma.
