Congenital anomalies of the optic nerve are perhaps the most frequently encountered and overlooked optic nerve disorders. They encompass a spectrum of optic nerve developmental abnormalities consisting of hypoplasia (reduced number of axons), dysplasia (disorganized axons), or other developmental traits that result in an unusual appearance. There are many variations that are characterized by abnormalities of size, shape and function of the nerve. Anomalous optic nerves can often mimic acquired optic neuropathies, and it is not unusual for patients to undergo expensive diagnostic work-ups or treatment in an effort to rule out or treat serious underlying disease. Understanding the various types of optic nerve anomalies and their clinical features is crucial to the appropriate management of this patient population, particularly given the frequency with which these types of problems present to all optometric patient populations.
