Neuro-ophthalmology
Neuro-ophthalmology is an academically-oriented subspecialty that merges the fields of neurology and ophthalmology, often dealing with complex systemic diseases that have manifestations in the visual system. Neuro-ophthalmologists initially complete a residency in either neurology or ophthalmology, then do a fellowship in the complementary field. Since diagnostic studies can be normal in patients with significant neuro-ophthalmic disease, a detailed medical history and physical exam is essential, and neuro-ophthalmologists often spend a significant amount of time with their patients.
Common pathology referred to a neuro-ophthalmologist includes afferent visual system disorders and efferent visual system disorders. The largest international society of neuro-ophthalmologists is the North American Neuro-Ophthalmological Society, which organizes an annual meeting and publishes the Journal of Neuro-Ophthalmology. Neuro-ophthalmologists are often faculty at large university-based medical centers. Patients often have co-existing diseases in other fields, thus the neuro-ophthalmologist is often a liaison between the ophthalmology department and other departments in the medical center.
Description
Neuro-ophthalmology focuses on diseases of the nervous system that affect vision, control of eye movements, or pupillary reflexes. Neuro-ophthalmologists often see patients with complex multi-system disease and exotic diagnoses—"zebras" in medical jargon—are not uncommon. Neuro-ophthalmologists are often active teachers in their academic institution, and the first four winners of the prestigious Straatsma American Academy of Ophthalmology teaching awards were neuro-ophthalmologists. Neuro-ophthalmology is mostly non-procedural, however, neuro-ophthalmologists may be trained to perform eye muscle surgery to treat adult strabismus, optic nerve fenestration for idiopathic intracranial hypertension, and botulinum injections for blepharospasm or hemifacial spasm.Historical developments
At the turn of the 20th century, there was no textbook in the English language on neuro-ophthalmology. In 1906, Dr. William Campbell Posey, Professor of Ophthalmology in the Philadelphia Polyclinic and Dr. William G. Spiller, Professor of Neurology in the University of Pennsylvania, edited The Eye and Nervous System: Their Diagnostic Relations By Various Authors J.B. Lippincott & Co. According to the Preface to this book, "Although it is generally conceded that a knowledge of neurology is indispensable to the ophthalmologist and that an acquaintanceship with ophthalmology is of the greatest service to the neurologist, there is no book in the English language which covers the ground where the two specialties meet."Frank B. Walsh was a pioneer of neuro-ophthalmology, helping to popularize and develop the field. Walsh was born in Oxbow, Saskatchewan in 1895 and earned a degree from University of Manitoba in 1921. He joined the Wilmer Ophthalmological Institute at Johns Hopkins University and began organizing Saturday morning neuro-ophthalmology conferences. Walsh compiled the first neuro-ophthalmology textbook, which was published in 1947 and has been updated over the years by generations of his students.
