Abstract

AbstractPurpose To study the relationship between RNFL thickness and rim thickness by Cirrus HD OCTMethods This prospective comparative study was conducted on 50 eyes from 50 glaucoma patients and 30 eyes from healthy 30 subjects. They were imaged by Cirrus HD OCT and the RNFL thickness and rim thickness data were analyzed. The correlations of the angles of the peaks in the RNFL thickness profile or rim thickness profiles with the axial length and spherical equivalent of refractive error (SE) were analyzed by simple linear regressionResults The global average RNFL thickness and rim thickness was significantly thinner in the glaucoma group than in the control group. The angles of the peaks in the RNFL thickness and rim thickness showed good correlation in both glaucoma and control group. Myopia affected the distribution of the peaks in the RNFL thickness and rim thickness. However, the effect were different between RNFL thickness and rim thicknessConclusion The rim thickness had good correlation with RNFL thickness. And the degree of glaucoma and myopia affected the distribution of RNFL thickness and rim thickness
