CCT was measured using OCT and USP. The optic nerve head (ONH) and retinal nerve fibre layer (RNFL) parameters were assessed with OCT and Heidelberg Retina Tomograph (HRT). Visual acuity and refraction were evaluated with an autorefractometer and intraocular pressure (IOP) with rebound tonometry (iCare) and Goldmann applanation tonometry (GAT). The evaluation of glaucomatous damage was based on the ONH, RNFL and visual fields.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n The mean CCT was 540.0\u2009\u00b1\u200934.8\u2009\u03bcm with OCT and 540.7\u2009\u00b1\u200939.6\u2009\u03bcm with USP. There was a strong correlation (\n r<\/jats:italic>\n \u2009=\u20090.927,\n p<\/jats:italic>\n \u2009<\u20090.001) between the devices, and the inter\u2010method agreement increased with better visual acuity (\n r<\/jats:italic>\n \u2009=\u20090.086,\n p<\/jats:italic>\n \u2009=\u20090.003). The CCT measured with OCT correlated with IOP (\n r<\/jats:italic>\n \u2009=\u20090.400 (iCare),\n r<\/jats:italic>\n \u2009=\u20090.314 (GAT),\n p<\/jats:italic>\n \u2009<\u20090.001), rim area (\n r<\/jats:italic>\n \u2009=\u20090.048,\n p<\/jats:italic>\n \u2009=\u20090.011), cup volume (\n r<\/jats:italic>\n \u2009=\u2009\u22120.046,\n p<\/jats:italic>\n \u2009=\u20090.014) and RNFL (\n r<\/jats:italic>\n \u2009=\u20090.041,\n p<\/jats:italic>\n \u2009=\u20090.027). We found no correlation between CCT and glaucoma.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n The results indicate that OCT and USP may be used interchangeably when measuring CCT. As expected, CCT had a substantial correlation with IOP, but was also positively associated with ocular neural tissue (rim and RNFL) and negatively with the optic cup.<\/jats:p>\n
