To correlate central cornea thickness (CCT) measurements with retinal nerve fiber layer (RNFL) in glaucoma patients.<br /> Hypothesis: subjects with thicker corneas have thicker nerve fiber layer.
Retrospective data review. CCT measurements taken with an optical pachymeter and RNFL evaluation done with optical coherence tomography (OCT) ganglion cell complex (GCC) protocol. Statistical analysis done with the Pearson’s correlation coefficient.
Sixty-three eyes of 63 patients with glaucoma or ocular hypertension; 30 were male and 33 female. There was no association between two variables (CCT and GCC). Pearson r and P values for the association between CCT and GCC average were 0.1425 and 0.265 respectively, for CCT and GCC superior were 0.1008 and 0.431, and for CCT and GCC inferior were 0.1571 and 0.218.
In patients with glaucoma and ocular hypertension the CCT does not correlate with the RNFL.
