title: Retinal nerve fiber layer and ganglion cell-inner plexiform layer thickness in children with obesity.
abstract: OBJECTIVE
  To evaluate retinal nerve fiber layer (RNFL) thickness analysis of peripapillary optic nerve head (PONH) and macula as well as ganglion cell-inner plexiform layer (GCIPL) thickness in obese children.
  
  
  METHODS
  Eighty-five children with obesity and 30 controls were included in the study. The thicknesses of the PONH and macula of each subject's right eye were measured by high-resolution spectral-domain optic coherence tomography (OCT).
  
  
  RESULTS
  The RNFL thicknesses of central macular and PONH were similar between the groups (all P>0.05). The GCIPL thickness was also similar between the groups. However, the RNFL thickness of temporal outer macula were 261.7±13.7 and 268.9±14.3 µm for the obesity and the control group, respectively (P=0.034).
  
  
  CONCLUSIONS
  Obesity may cause a reduction in temporal outer macular RNFL thickness.
