  • Optic neuritis typically presents with subacute visual loss and periocular pain that often resolve spontaneously. (epainassist.com)
  • OCT at onset of ON is also potentially confounded by edema of the optic disc, which may lead to overestimates of baseline RNFL.4 Ganglion cell layer (GCL) thickness, another OCT measure, is not confounded by disc edema but declines in a similar time frame to RNFL and therefore may be more useful as a baseline measurement.
