title: Association between retinal thickness of 64 sectors in posterior pole determined by optical coherence tomography and axial length and body height.
abstract: OBJECTIVE
  We determined a significant correlation between the retinal thickness (RT) in 64 cells or sectors of the posterior pole, and the axial length (AL) and the body height (BH).
  
  
  METHODS
  A prospective, observational cross-sectional study of 64 right eyes of 64 healthy volunteers (mean age, 26.0 ± 4.5 years; range, 22-39 years). The RT within the central 24° area was measured in the Spectralis spectral domain-optical coherence tomographic (SD-OCT) images. The correlations between the RT and the AL or the BH were determined by linear regression analyses.
  
  
  RESULTS
  The mean ± SD of the AL was 25.04 ± 1.30 mm, and that of the BH was 167.2 ± 8.5 cm. The RTs of the central four cells around the fovea were not significantly correlated with the AL. The RTs of 54 cells were significantly and negatively associated with the AL (r = -0.25 to -0.56, P < 0.05). In contrast, the RTs of the central to temporal eight cells were significantly and positively correlated with the BH (r = 0.26-0.37, P < 0.05). The RTs of 56 cells were not significantly correlated with the BH.
  
  
  CONCLUSIONS
  The RT of the posterior retina, except in the fovea, decreased as AL elongated, and those of the central temporal areas were significantly correlated with the BH. Thus, the AL and BH must be considered when the RT is evaluated. The 64-sector analysis on OCT is useful to assess the detailed changes of RT affected by them.
