Myelinated nerve fiber layer with visual field defect
Contributor: Luke Lenci, MD

This is an example of a prominent myelinated nerve fiber layer. These can have corresponding visual field defects as seen here on Goldmann perimetry with depression of the I4e, I3e, and I2e isopters in the region of the myelination. This is an unusual case as it is located along the horizontal raphe; typically, the myelin is peripapillary in location.
