Myelinated Nerve Fiber Layer

Posted by

Myelinated retinal nerve fiber layer (RNFL) is found in a dilated eye examination.  It can vary in size and location and presents as well-demarcated, white patch of myelinated retinal ganglion cell axons. While a benign finding, it can be associated with eye conditions that affect vision, such as lazy eye or crossed eyes. The cause of myelinated nerve fibers is unknown. There is no treatment for myelinated nerve fibers. Fortunately, most patients with this condition do not have vision loss from it.
