Rollet1 grouped tumors in the region of the sella turcica into four classes with respect to ocular signs: (1) the optic or amaurotic form, in which the signs are the result of compression of the visual fibers and which includes the familiar chiasmal syndrome and bitemporal hemianopia; (2) the sensorimotor and cavernous or vascuiar form, in which the signs are the result of pressure on the trunks of the ocular nerves in the wall of the cavernous sinus and on the cavernous sinus itself ; (3) the total or opticocavernous form, combining signs of the first two forms, and (4) the exophthalmic form, in which the predominant sign is proptosis.
