Optic chiasm compression icd 10
WebObjective: Pituitary tumours that compress the optic chiasm are associated with long-term alterations in sleep-wake rhythm. This may result from damage to intrinsically photosensitive retinal ganglion cells (ipRGCs) projecting from the retina to the hypothalamic suprachiasmatic nucleus via the optic chiasm to ensure photoentrainment (i.e., … WebLesions solely of the chiasm rarely cause optic disk swelling without third ventricular compression, but chronic processes may lead to optic atrophy. Seesaw nystagmus can occur in association with sellar lesions, and the presence of ocular motor palsies suggests cavernous sinus involvement (see "Disorders of Eye Movements" later in this chapter).
