The assessment of peripapillary retinal nerve fiber layer and macular ganglion cell layer changes in obese children: a cross-sectional study using optical coherence tomography.

Thinning in RNFL was detected in normal-looking discs of obese children, and this thinning negatively correlated with BMI SDS. Further studies including large series are needed to clarify whether obesity has an effect on RNFL thickness.
