Spectral-domain optical coherence tomography assessment of an epiretinal membrane with axoplasmic stasis from nerve fiber layer traction.
OBJECTIVE
To report a case of visible axoplasmic stasis on fundus examination correlating with spectral-domain optical coherence tomography findings of nerve fiber layer traction.


METHODS
Case report.


RESULTS
Spectral-domain optical coherence tomography images show nerve fiber layer traction and distortion at the sites where visible cotton wool spot-like changes were seen on examination. These visible changes are likely because of axoplasmic stasis from the severe traction on the nerve fiber layer.


CONCLUSIONS
Spectral-domain optical coherence tomography demonstrates that cotton wool spot-like changes may be caused by nerve fiber layer traction in some epiretinal membranes. This is of interest in understanding the pathophysiology of these changes.
