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.

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:

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 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 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.

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.

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.

You must wear sunglasses to prevent damage to your eyes. While some contact lenses provide UV protection, they don't cover your whole eye, so you still need sunglasses. Look for sunglasses that protect you from 99% to 100% of both UVA and UVB light. This includes those labeled as "UV 400," which blocks all light rays with wavelengths up to 400 nanometers. (This covers all of UVA and UVB rays.

The aim of all Ultralase vision correction is to improve your eyesight. Everything we do is targeted to achieve that, from the equipment we install to the recruitment of highly-skilled specialists, from the procedures we follow to the assessments we make. In a minority of cases, there is need for retreatment. Read the safety and risks section for more detail. Recent evidence suggests that stability of outcome is excellent for ten or more years post-treatment.

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.

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).

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.

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.

No. Just use caution not to look directly into the laser's aperture. If you accidentally glance into the laser light, you will be fine; no harm will occur. Always follow directions and read warning stickers.

You can help keep your nervous system healthy by keeping your blood glucose as close to normal as possible, getting regular physical activity, not smoking, taking good care of your feet each day (see below), having your health care provider examine your feet at least 4 times a year, and getting your feet tested for nerve damage at least once a year.

No. One is usually given a pair of special glasses to protect the eyes. There are no other harmful effects from the laser

It depends on the nerve that is having the compression, which would affect the muscles it supplies, as well as the sensibility of the skin and tendons (your doctor could tell you about that). Usually walking is affected, most commonly there will be weakness to tiptoe or foot drop. There could also be urine retention, loss of sphincter control, impotence, etc.

Children under the age of seven are still learning to focus and track with their eyes. Their vision is still immature. For this reason the DV920 should not be used by children under the age of 7. For anyone over 7, watching stereoscopic 3D movies or other 3D content with a device like this causes your eyes to focus at a constant distance while your mind perceives the images are closer or further away. For some people this can cause eyestrain, or headaches after prolonged use.

My right top front tooth is absest, other than what is under the gum line the tooth is a healthy tooth though chipped at one time,,,, do they have to pull the tooth or is there any way they could save it from total loss when i go see a dentist ...... being i also have four molars upper and lower on either side that already have to b removed ..... id like to at least keep the fronts but with out the pain of an infection or absess ....... I have a white spot on my front tooth.

Trauma and physical irritation are the two common causes of pulp nerve damage. Sensitive nerve tissue within the tooth can be damaged by trauma to a tooth. This may be a result of a tooth being struck heavily. Physical irritation stems from the spreading of tooth decay to the nerve. The result is decay and infection as destructive bacteria comes into contact with the nerve.
