WHO IS A NEURO-OPHTHALMOLOGIST?
Neuro-ophthalmologists take care of visual problems that are related to the nervous system; that is, visual problems that do not come from the eyes themselves. We use almost half of the brain for vision-related activities, including sight and moving the eyes. Neuro-ophthalmology, a subspecialty of both neurology and ophthalmology, requires specialized training and expertise in problems of the eye, brain, nerves and muscles. Neuro-ophthalmologists complete at least 5 years of clinical training after medical school and are usually board certified in Neurology, Ophthalmology, or both.
Although some problems seen by neuro-ophthalmologist are not worrisome, other conditions can worsen and cause permanent visual loss, or become life threatening. Sometimes the problem is confined to the optic nerve or the nervous system and other times it is related to a general medical condition. Neuro-ophthalmologists have unique abilities to evaluate patients from the neurologic, ophthalmologic, and medical standpoints to diagnose and treat a wide variety of problems. Costly medical testing is often avoided by seeing a neuro-ophthalmologist.
Some of the common problems evaluated by neuro-ophthalmologists include: optic nerve problems (such as optic neuritis and ischemic optic neuropathy), visual field loss, unexplained visual loss, transient visual loss, visual disturbances, double vision, abnormal eye movements, thyroid eye disease, myasthenia gravis, unequal pupil size, and eyelid abnormalities.
Dr. Wayne Bixenman is a board certified ophthalmologist and is one of the few providers who specialized in this field in the entire state of Arizona. He specializes in visual disturbances that relate to the nervous system. This includes loss of sight due to injury to the brain or the optic nerve.About Dr. Bixenman
PREPARING FOR THE NEURO-OPHTHALMOLOGY EVALUATION
Request that your treating physicians send all relevant information to the neuro-ophthalmologist prior to your appointment, including office notes, results of laboratory tests and reports of CT and MRI scans.
If you have had a CT or MRI scan performed, arrange to pick up the actual films and bring them with you, or have the facility mail them to the neuro-ophthalmologist in advance or your appointment.
You will probably have your pupils dilated during the visit. The eye drops last about 4 hours and will make things look bright and blurry up close. Have someone else drive you to the appointment and bring your sunglasses.
Bring a complete list of medications with you, including the name and dosage of prescription and over-the-counter medications.
WHAT HAPPENS DURING THE EVALUATION?
The neuro-ophthalmologic evaluation is one of the most comprehensive examinations you will experience. It may take a few hours to complete. You will be asked to give an account of your current problem and relate your entire medical history, including previous hospitalizations, operations, serious illnesses, medical problems in your family members, and medication allergies.
You will have a complete eye examination. This may include testing of your peripheral vision (visual field test).
You may have a partial or complete neurologic exam to test your strength, sensation, and coordination.
The neuro-ophthalmologist will review the records and scans from previous evaluations, if applicable.
After the examination, the neuro-ophthalmolgist will discuss the diagnosis (or possible diagnoses), the need for any additional testing and possible treatment.
