title: Peripapillary retinal nerve fiber layer thickening associated with vitreopapillary traction.
abstract: OBJECTIVE
  To report two cases of retinal nerve fiber layer (RNFL) thickening as measured by Cirrus high-definition spectral-domain optical coherence tomography (OCT) associated with vitreopapillary traction.
  
  
  METHODS
  Consecutive peripapillary RNFL thickness assessments were performed using OCT in eyes with glaucoma and ocular hypertension.
  
  
  RESULTS
  OCT measurements revealed RNFL thickening when compared with the prior examination. A vitreopapillary traction to the thickened side of the RNFL was noted in a cross-sectional image of the optic nerve head obtained by OCT.
  
  
  CONCLUSIONS
  Given that RNFL thickening can mask glaucomatous changes of the RNFL, caution is needed in glaucoma evaluation in eyes with vitreopapillary traction to the RNFL.
