Inherited optic neuropathies (IONs) cover a spectrum of clinically and genetically heterogenic conditions. Genetic evaluation of patients with IONs may enable their better clinico-diagnostic assessmen...
Mitochondrial optic neuropathies such as Leber's Hereditary Optic Neuropathy (LHON) and Dominant Optic Atrophy (DOA) have been shown to produce an optic neuropathy secondary to retinal ganglion cell l...
This study compares the age-related clinical features of thyroid eye disease-compressive optic neuropathy (TED-CON) to those with noncompressive disease (TED-NC).
Ewing sarcoma localized in the paranasal sinuses, compressing the optic nerve, is very rare, with no prior case reports PATIENT CONCERNS:: A 68-year-old woman presented with decreased visual acuity in...
This paper is a practical survey of immune-mediated, inflammatory and hereditary neuropathies along with recommendations for diagnostic procedures. The large group of immune-mediated, inflammatory neu...
The participant is being asked to be a subject in this research study because the participant may have a disorder that can cause optic nerve damage and impairment of his/her visual functio...
Method for diagnostics of the origin of infections (bacterial vs viral) based on the identification of activation markers of blood neutrophils and monocytes will be developed.
A single arm, single center trial to assess the safety and efficacy of restoring function in damaged optic nerves using autologous purified populations of bone-marrow derived stem cells (B...
Compressive stockings ameliorate functional outcome and quality of life in patients after elective orthopedic foot and ankle surgery. In this randomized controlled trial the investigators ...
Non-arthritic anterior ischemic optic neuropathy is the most common cause of sudden visual loss due to optic nerve involvement in patients above 50 years old. As this problem can be consid...
Atrophy of the optic disk which may be congenital or acquired. This condition indicates a deficiency in the number of nerve fibers which arise in the RETINA and converge to form the OPTIC DISK; OPTIC NERVE; OPTIC CHIASM; and optic tracts. GLAUCOMA; ISCHEMIA; inflammation, a chronic elevation of intracranial pressure, toxins, optic nerve compression, and inherited conditions (see OPTIC ATROPHIES, HEREDITARY) are relatively common causes of this condition.
Conditions which produce injury or dysfunction of the second cranial or optic nerve, which is generally considered a component of the central nervous system. Damage to optic nerve fibers may occur at or near their origin in the retina, at the optic disk, or in the nerve, optic chiasm, optic tract, or lateral geniculate nuclei. Clinical manifestations may include decreased visual acuity and contrast sensitivity, impaired color vision, and an afferent pupillary defect.
8-Hydroxyquinolinols chlorinated on the number 5 and/or 7 carbon atom(s). They are antibacterial, antiprotozoal, and antidiarrheal, especially in amebiasis, and have also been used as antiseborrheics. The compounds are mostly used topically, but have been used also as animal feed additives. They may cause optic and other neuropathies and are most frequently administered in combination with other agents.
Ischemic injury to the OPTIC NERVE which usually affects the OPTIC DISK (optic neuropathy, anterior ischemic) and less frequently the retrobulbar portion of the nerve (optic neuropathy, posterior ischemic). The injury results from occlusion of arterial blood supply which may result from TEMPORAL ARTERITIS; ATHEROSCLEROSIS; COLLAGEN DISEASES; EMBOLISM; DIABETES MELLITUS; and other conditions. The disease primarily occurs in the sixth decade or later and presents with the sudden onset of painless and usually severe monocular visual loss. Anterior ischemic optic neuropathy also features optic disk edema with microhemorrhages. The optic disk appears normal in posterior ischemic optic neuropathy.

Nerve fiber originating from the OPTIC CHIASM that connects predominantly to the LATERAL GENICULATE BODIES. It is the continuation of the VISUAL PATHWAY that conveys the visual information originally from the RETINA to the optic chiasm via the OPTIC NERVES.
