Abstract

Purpose: To compare the performance of glaucoma diagnosis according to the macular and peripapillary retinal nerve fiber layer (RNFL) thicknesses, as determined by spectral domain optical coherence tomography (OCT).
Methods: Ninety-six normal, 63 early glaucoma and 37 moderate to advanced glaucomatous eyes were imaged by Cirrus OCT. The areas under the receiver operating characteristics curves (AUCs) of macular and RNFL thicknesses were calculated for discrimination of normal and glaucomatous eyes. The sensitivity and specificity of normative classification of each parameter were assessed.
Results: The glaucoma diagnostic capability determined by AUC was greater when based on the peripapillary RNFL than the macular thickness (0.914, 0.775, p<0.001). Both the early and the moderate-to-advanced group showed higher AUCs in peripapillary RNFL thickness (early glaucoma group; 0.870, 0.670, p<0.001, moderate to advanced glaucoma group; 0.990, 0.954, p=0.03). The inferior outer sector of macular thickness showed highest sensitivity among the parameters (58%).
Conclusions: Although Cirrus OCT applied to determine macular thickness did not outperform that applied to determine peripapillary RNFL thickness in glaucoma diagnosis, applying Cirrus OCT to determine both thicknesses in diagnosis may help in understanding a patient’s status.
