CIBA Vision Ophthalmics - Digital Grand Rounds
Digital Grand Rounds Program - Answer/Discussion
This is a case of medulated nerve fibers. The sheer size of the area
of myelination is unusual, as well as the fact that these fibers do
not originate at the optic nerve, which is the norm.
Medulated nerve fibers are considered a normal retinal variation and
are of not significant concern. They are not progressive, but should
be considered if visual field defects are ever found in such a
patient. Myelination can cause field loss in the overlying area.
See you next time!
