Some possibilities: Tumor may grow nearby visual pathways, and some tumors directly affect the optic nerve or chasm. Others may dramatically increase intracranial pressure by mass effect, which indirectly can cause visual loss. In fact, any increased pressure for a variety of reasons can cause obscurational episodes.
