The ciliary body and ligamentum pectinatum become invaded early in the disease. The involvement of the latter causes increase of tension by preventing filtration from the eye. Extension of growth along the walls of the canal of Schlemm, or the anterior perforating vessels, gives rise to the formation of extraocular nodules.
