Comparative assessment for the ability of Cirrus, RTVue, and 3D-OCT to diagnose glaucoma.

Abstract:

PURPOSE:We compared the ability of circumpapillary retinal nerve fiber layer (cpRNFL) thickness and macular parameters obtained by three spectral-domain optical coherence tomography (SD-OCT) instruments to detect glaucoma. METHODS:We enrolled 87 normal eyes and 145 glaucomatous eyes (75 early glaucomatous eyes (EGs), mean deviation > -6 dB). Each participant was imaged using Cirrus, RTVue, and 3D-OCT to evaluate the average and quadrant cpRNFL thicknesses. The macular retinal nerve fiber layer (mRNFL), ganglion cell layer plus inner plexiform layer (GCL/IPL), and mRNFL + GCL/IPL (ganglion cell complex [GCC]) thicknesses were analyzed. The areas under the receiver operating characteristic curves (AUCs) were compared among the instruments. RESULTS:These instruments revealed similar AUCs for the average cpRNFL and GCC thicknesses in EGs, and total all-stage glaucomatous eyes (TGs). RTVue showed better performance in the nasal cpRNFL thickness than Cirrus and 3D-OCT, and better performance in the temporal cpRNFL thickness than 3D-OCT in TGs. RTVue had a higher AUC for the superior GCC thickness compared to Cirrus and 3D-OCT in EGs, and TGs. Cirrus had higher AUCs for GCL/IPL parameters in TGs, and lower AUCs for the mRNFL parameters in EGs and TGs compared to 3D-OCT. CONCLUSIONS:The average cpRNFL and GCC thicknesses measured using these OCT instruments exhibited similar abilities in the diagnosis of glaucoma, and RTVue exhibited better diagnostic abilities than Cirrus and 3D-OCT for nasal cpRNFL, and superior GCC thicknesses. The diagnostic performance of Cirrus and 3D-OCT was different for GCL/IPL and mRNFL parameters. (http://www.umin.ac.jp/ctr number, UMIN000006900.)
