The optic nerve is a bundle of more than 1 million nerve fibers. Nerve signals travel along the optic nerve from each eye and send visual information to the brain. Damage along the optic nerve pathway causes specific patterns of vision loss. The three types of vision loss caused by optic nerve disorders are There are many different types of optic nerve disorders, including: Glaucoma is a group of diseases that are the leading cause of blindness in the United States. Glaucoma usually happens when the fluid pressure inside the eyes slowly rises and damages the optic nerve. Optic neuritis is an inflammation of the optic nerve Optic nerve anomalies can be categorized as congenital or acquired. Congenital anomalies can be further subdivided into benign or pathologic. Acquired abnormalities are assumed to be pathologic, and generally are described with respect to optic nerve's reaction to a given insult (i.e., cupping, swelling or atrophy). Optic nerve hypoplasia is a principal feature of septo-optic dysplasia of de Morsier, a developmental disorder characterized by the association of anomalies of the midline structures of the brain with hypoplasia of the optic nerves, optic chiasm, and optic tracts; typically noted are agenesis of the septum pellucidum, partial or complete agenesis of the corpus callosum, and malformation of the fornix, with a large chiasmatic cistern

Abstract Congenital optic nerve head anomalies are a group of structural malformations of the optic nerve head and surrounding tissues, which may cause congenital visual impairment and blindness Damage to an optic nerve or damage to its pathways to the brain results in loss of vision. At a structure in the brain called the optic chiasm, each optic nerve splits, and half of its fibers cross over to the other side. Because of this anatomic arrangement, damage along the optic nerve pathway causes specific patterns of vision loss Optic nerve Optic neuritis occurs when swelling (inflammation) damages the optic nerve — a bundle of nerve fibers that transmits visual information from your eye to your brain. Common symptoms of optic neuritis include pain with eye movement and temporary vision loss in one eye

Disorders of the optic nerve and retina are common causes of afferent visual loss in clinical neurology. The diagnosis of optic neuropathy should be considered when visual loss (affecting visual acuity, color vision, or visual field) is accompanied by abnormal optic disc appearance or a relative afferent pupillary defect (RAPD; see Chapter 17) Optic nerve aplasia denotes total absence of the optic nerve, retinal blood vessels, and retinal ganglion cells. It is a rare condition, most commonly unilateral, and associated with microphthalmos, retinochoroidal colobomas, and cataracts. No light perception visual acuity and an afferent pupillary defect are common findings Disorders of the optic nerve The optic nerve, which carries about one million nerve fibres, leaves the globe from the back of the eye and passes through the apex of the orbit into the cranial cavity. It is surrounded by an extension of the membranes that surround the brain Optic Nerve Disorders Optic Neuritis and Optic Neuropathy Duke's neuro-ophthalmologists are subspecialists who conduct extensive evaluations to identify the cause of visual concerns including unexplained visual loss, blurred vision, and blind spots that may be related to optic nerve damage (optic neuropathy)

  1. Optic nerve hypoplasia (ONH) is a congenital disorder characterized by underdevelopment (hypoplasia) of the optic nerves. The optic nerves transmit impulses from the nerve-rich membranes lining the retina of the eye to the brain
  2. Optic Nerve Hypoplasia (ONH) is the under-development or absence of the optic nerve combined with possible brain and endocrine abnormalities. It is also known as Septo-Optic Dysplasia or DeMorsier's Syndrome. Now at epidemic proportions, ONH is the leading ocular cause of blindness and visual impairment in young children
  3. Optic neuropathy describes abnormalities of the optic nerve [ 8 ].This may occur as a result of ischaemia, vascular and blood pressure abnormalities, toxins, compression, infiltrations and trauma [ 9, 10 ]
  4. The optic nerve from each eye carries impulses to the brain, where visual information is interpreted. Damage to an optic nerve or damage to its pathways to the brain results in loss of vision. At a structure in the brain called the optic chiasm, each optic nerve splits, and half of its fibers cross over to the other side
  5. Optic nerve colobomas are associated with defects in the PAX6 gene. It is associated with microphthalmos and serous retinal detachments. Retinal/choroidal colobomas are associated with rhegmatogenous retinal detachments

The short intraocular course of the optic nerve is often referred to as the optic nerve head, and the portion that can be seen with the ophthalmoscope is called the optic disc. The optic disc is usually oval, measuring about 1.5 by 1.75 mm, with its long axis typically oriented vertically. In most subjects, the optic cup, devoid of axons, is. The adjacent air-filled paranasal sinuses and skull base create large magnetic field inhomogeneities that result in geometric distortions and signal drop-out that can mask optic nerve abnormalities. This problem is exaggerated at higher magnetic field strengths or in echoplanar techniques where long echo-train lengths are required to generate. The ophthalmologist, on examining the patient, may find elevated intraocular pressure, optic-nerve abnormalities, or visual field loss in addition to other less common signs. The eyes of patients with acute angle-closure glaucoma will appear red, and the pupil of the eye may be large and nonreactive to light When optic nerve hypoplasia occurs with an absence of the septum pellucidum, it is known as septo-optic dysplasia or eponymously de Morsier syndrome..

It is characterized by a reduced number of ganglion cell axons within the optic nerve, and it can occur in isolation or associated with other CNS abnormalities. When optic nerve hypoplasia occurs in conjunction with midline brain abnormalities, the absence of the septum. The optic nerve head is the most anterior component of the optic nerve and corresponds to the 1 mm segment that is located within the eyeball (i.e. the intraocular part).

The pathophysiology and visual significance of these retinal changes remain unclear, but may affect the diagnosis and management of optic nerve disorders. INTRODUCTION Optical coherence tomography (OCT) is a well The optic nerve is composed of retinal ganglion cell axons and glial cells.Each human optic nerve contains between 770,000 and 1.7 million nerve fibers, which are axons of the retinal ganglion cells of one retina. In the fovea, which has high acuity, these ganglion cells connect to as few as 5 photoreceptor cells; in other areas of retina, they connect to many thousand photoreceptors We investigated the clinical characteristics and associated ocular and systemic anomalies in young children with congenital optic nerve abnormalities, and evaluated the therapeutic results of treatment for strabismus and amblyopia. A retrospective study was conducted using the medical records of patients who were diagnosed with congenital optic nerve abnormalities in our hospital between 1995. OPTIC NERVE HYPOPLASIA (ONH) is the most common congenital anomaly of the optic disc. It may be an isolated finding or part of a spectrum of anatomical and functional abnormalities, which include partial or complete agenesis of the septum pellucidum (SP), other midline brain defects (e.g. thin or absent corpus callosum, dysplasia of the anterior third ventricle), cerebral anomalies (of.
