The primary subspecialities involved in the Tumors of the Optic Nerve Initiative are ophthalmology, neurology, neurosurgery, cancer therapy, and radiation therapy. The U.S. News and World Report survey identified these specialites as some of "America's Best" including ophthalmology (6th), neurology/neurosurgey (9th), and cancer (38th).

A multidisciplinary approach to these tumors enhances patient care. Patients benefit from a coordinated clinical service that is "under one roof". The disciplines that currently participate in the care of these patients include:

Radiation therapy. New and emerging modalites in radiation therapy allow more advanced treatment of optic nerve lesions and spare surrounding brain, retina, and contralateral optic nerve. These modalities include stereotactic radiotherapy and radiosurgery and conformal intensity modulated radiotherapy. Pediatric and adult neuro-oncology. The oncologists at the Holden Cancer Center have tremendous experience with chemotherapy and the medical treatment of tumors.

The goal of the Optic Nerve Center is to provide high quality and cutting edge evaluation and treatment for patients with tumors affecting the optic nerve. The Center hopes to develop and study new and emerging treatments for optic nerve tumors and to serve as a national model for innovative and novel approaches to optic nerve tumors. The Center's purpose is to serve as a focal point and centerpiece of a multidisciplinary approach to these tumors.

The development of a large tumor registry for optic nerve meningiomas would also enhance care for these patients. Surgical resection is reserved for patients with severe proptosis or complete or near complete visual loss. Chemotherapy and hormonal therapy have not proven to be effective. New modalities of radiation therapy are currently the mainstay of therapy but no prospective study with large numbers of patients has been performed to date.

The optic nerve is a bundle of more than 1 million nerve fibers. It connects the retina to the brain.

A primary optic nerve tumor is one that arises from the optic nerve itself or its covering (the meninges). The two most primary common optic nerve tumors are optic glioma and optic nerve meningioma.

A secondary optic nerve tumor arises from the brain or adjacent structures but compresses the optic nerve and produces symptoms.

Optic glioma is typically a tumor of childhood. It may be associated with an inherited disorder known as neurofibromatosis I. The symptoms of optic glioma are usually related to visual loss due to compression of the optic nerve. Bulging of the eye (proptosis), double vision (ocular misalignment), and drooping of the eyelid (ptosis) may also occur.

Optic nerve sheath meningioma is typically a tumor of adulthood and is seen more frequently in middle aged women. The symptoms of optic nerve sheath meningioma are usually related to visual loss due to compression of the optic nerve. Bulging of the eye (proptosis), double vision (ocular misalignment), and drooping of the eyelid (ptosis) may also occur.

In order for people to "see", the brain must receive the messages sent from the eye. The optic nerves carry this information from the eye to the brain. If this nerve is too small, less information will be sent to the brain, and vision will be impaired. Hypoplasia means "underdeveloped". This may mean that the nerves of both eyes are completely unformed, with complete blindness, or that one optic nerve is smaller than average, with little impact on vision.

Optic pathway gliomas are uncommon and consequently few centers have a large experience. The development and study of a large prospective tumor registry (collection of patients over time) would definitely enhance care and advance the field. There is no universally accepted staging system for visual and hypothalamic gliomas. Prospective natural history data might improve our ability to predict the behavior of tumors based upon location or other factors (e.g. association with neurofibromatosis I).

No, the laser that is used to get fine detailed images is not a treating laser. It has no significant energy. It has no more effect on your eyes than a standard photograph flash would.

When a patient has glaucoma or is at high risk for developing the disease, physicians may document how the optic nerve changes over time by making drawings, taking photographs, or using a new technique called optic nerve imaging. Scanning laser polarimetry (GDx), confocal scanning laser ophthalmoscopy (Heidelberg Retinal Tomograph or HRT II), and optical coherence tomography (OCT) are all examples of optic nerve imaging techniques.

In many people, increased pressure inside the eye causes glaucoma. In the front of the eye is a space, called the anterior chamber. A clear fluid flows continuously in and out of this space and nourishes nearby tissues. The fluid leaves the anterior chamber at the angle where the cornea and iris meet. When the fluid reaches the angle, it flows through a spongy meshwork, like a drain, and leaves the eye.

The command is made up of four major directorates: aviation, afloat, shore, and OSH. We also have seven support departments: legal, business and management, administrative, marketing and public affairs, information management systems, statistics and mathematics, and media.

In the front of the eye is a space called the anterior chamber. A clear fluid flows continuously in and out of the chamber and nourishes nearby tissues. The fluid leaves the chamber at the open angle where the cornea and iris meet. When the fluid reaches the angle, it flows through a spongy meshwork, like a drain, and leaves the eye. Sometimes, when the fluid reaches the angle, it passes too slowly through the meshwork drain.

The neurovascular bundles or nerve bundles, one on the left side of the prostate and one on the right side carry nerves and blood to assist in achieving an erection. If surgery is chosen as the treatment of the cancer, these bundles may or may not be spared.

Yes. The UNC School of Pharmacy places full-time faculty in each of the regional AHECs. Pharmacy faculty in the AHECs coordinate, supervise, precept, and administer the Professional Experience Program.

According to the NFPA’s 2002 National Fire Experience Survey, there are an estimated 30,310 fire departments in the U.S. 12% of all departments are all career or mostly career but protect 60% of the U.S. population, while 88% of the departments are mostly volunteer or all volunteer and protect 40% of the population.

Dues are reduced to $11.50 per month for Emeriti members. This reduction in your fees would take effect as soon as you notify the Faculty Center office of your retirement in writing .

If you have logged on to SPIRE with the correct instructor ID, and on your Faculty Center, you cannot see the current term in the Select Term drop-down list, you have not been listed as an instructor for any course this semester. If you are currently teaching and know you have grading authority, contact the academic support staff in your department. They will work with the Registrar's Office to list you as an instructor with grading authority.

Contact the academic support staff in your department. They will notify the Registrar's Office that your name should be associated with the class in a grading capacity.
