Correlation between Retinal Nerve Fiber Layer Thickness and Central Corneal Thickness in Healthy Subjects.
OBJECTIVE
To evaluate the correlation between retinal nerve fiber layer (RNFL) thickness obtained by optical coherence tomography (Spectralis OCT Heidelberg Engineering, Heidelberg, Germany) and central corneal thickness (CCT) in healthy subjects.


METHODS
This was a retrospective cross-sectional study. Two hundred twenty nine healthy subjects were included in the present study. All subjects received a standard ocular examination, including RNFL thickness measurement by optical coherence tomography. CCT measurement was performed by ultrasonic pachymeter. The Pearson's correlation test was used to determine the relationship between CCTandRNFL thickness.


RESULTS
The significantly positive relationship was found between CCTand RNFL thickness in overall average and inferior sector. There was no statistically significant relationship found between CCT and the other sectors of RNFL thickness.


CONCLUSIONS
CCT was statistically significant related to RNFL thickness in overall average and inferior sector in healthy subjects.
