    The optic nerve is composed of nerve fibers that transmit impulses to the brain. In the case of optic atrophy, something is interfering with the optic nerve's ability to transmit these impulses. [my.clevelandclinic.org]

    It interrupts the nerve impulses that communicate visual information to the brain. It can develop slowly and progress gradually, or can, in some instances occur suddenly and progress rapidly. [disabilitybenefitscenter.org]

    Optic atrophy is an ophthalmic condition that affects the optic nerve, which is responsible for carrying impulses from the eyes to the brain. The term “atrophy” indicates the process of deterioration or wasting away. [hxbenefit.com]

    A small degree of gliosis is usually present and primarily represents a proliferation of astrocytes. This gliosis is not as severe as in inflammations of the optic nerve. [test.aneskey.com]

    General Pathology In optic nerve atrophy there is loss of axons and shrinkage of myelin leading to gliosis and widening of the optic cup. Primary prevention Optic atrophy is the end stage of a process causing damage to the optic nerve. [eyewiki.aao.org]

Surgical repair with lysis of adhesions and packing of the sella has been reported to improve visual prognosis. Delayed radionecrosis of chiasm and optic nerves Late delayed radiation effect on the central nervous system is well known. [pituitary.org]

Unfortunately, a prompt diagnosis is of extreme importance, since the sooner an appropriate treatment is initiated, the better the prognosis and the less probability of permanent visual damage. [frontiersin.org]

In 27 % of the cases no cause could be found while in the rest of 73% cases definite etiological factor was present. [ijo.in]

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. [icd10coded.com]

EPIDEMIOLOGY AND PATHOGENESIS The most common optic neuropathies in young and older adults are optic neuritis and nonarteritic anterior ischemic optic neuropathy, respectively. [medtextfree.wordpress.com]

Pathophysiology The optic nerve comprises approximately 1.2 million axons that originate at the ganglion cell layer of the retina. [thehealthscience.com]

Traumatic optic neuropathy The exact pathophysiology of traumatic optic neuropathy is poorly understood, although optic nerve avulsion and transection, optic nerve sheath hematoma, and optic nerve impingement from a penetrating foreign body or bony fragment [emedicine.medscape.com]

Pathophysiology There is a loss of axons and shrinkage of myelin, leading to widening of the optic cup. Presentation [ 1 ] This depends on the causative condition. Optic disc atrophy in isolation results in the following symptoms and signs. [patient.info]

Pathophysiological mechanisms which relate these two distinct disease entities include compressive optic neuropathy secondary to mucoceles, direct extension of sinus infection to the optic nerve from suppurative paranasal sinusitis, from osteomyelitis [ruralneuropractice.com]

The pathophysiology of non-arteritic anterior ischemic optic neuropathy is not known, but is related to impoverished circulation in optic nerve head. [hxbenefit.com]

Many causes of optic nerve atrophy cannot be prevented. Prevention steps include: Older adults should have their provider carefully manage their blood pressure. Use standard safety precautions to prevent injuries to the face. [medlineplus.gov]
