Compression of the optic chiasm causes an optic neuropathy that may be associated with
reversible visual loss often immediately following surgical decompression. While the precise …

Indirect traumatic optic neuropathy (ITON) refers to optic nerve injury resulting from impact
remote to the optic nerve. The mechanism of injury is not understood, and there are no …

Purpose: Although it is a commonly held belief that stretching of the optic nerve is important
in dysthyroid optic neuropathy (DON), it is probably mainly due to microvascular ischemia …

Methods A prospective observational study involving 40 patients with indirect TON was
conducted. Ocular, neuro-ophthalmological, radiological, and neurophysiological variables …

A recent anatomical study of the human optic chiasm cast doubt on the widespread
assumption that nerve fibres travelling in the human optic nerve and chiasm are arranged …

Purpose: Hemidecussation of fibers entering the optic chiasm from the optic nerves is well
recognized. The reason why bitemporal hemianopia results from chiasmal compression has …

The optic nerve is a white matter tract that conveys visual information to the brain. The sclera
comprises the white, protective outer layer of the eye. A characterization of the proteome of …

Although there have been many studies of the arterial cerebral blood supply, only seven
have described the optic chiasm (OC) blood supply and their results are contradictory. The …

The optic chiasm is an important neuroanatomic landmark, in particular as it relates to the
pituitary gland and endocrinologic syndromes. Pathology that affects the chiasm helps …

Background: Compression of the optic chiasm by pituitary tumors typically results in
bitemporal hemianopia, implying that nasal retinal fibers are preferentially damaged. The …
