This is an opacity of the eyeball, a whitish, opaque spot, which gradually enlarges and has generally ended in blindness. It is supposed to be incurable by our best authorities, generally occurring in aged dogs - these are evidences of failing health and probable breaking up of the system. It frequently follows ophtalmia, but might be the result of inflammation or a wound, or blow. My Eye Lotion No. 2 will do some good even in such cases.
