title: The ability of macular parameters and circumpapillary retinal nerve fiber layer by three SD-OCT instruments to diagnose highly myopic glaucoma.
abstract: OBJECTIVE
  To compare 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 highly myopic glaucoma.
  
  
  METHODS
  In this study, 84 glaucomatous eyes, 53 normal eyes with high myopia, and 86 normal eyes (not highly myopic) were enrolled. 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 + inner plexiform layer (GCL/IPL), and mRNFL + GCL/IPL (GCC) thicknesses were analyzed. The areas under the receiver operating characteristic curves (AUCs) were compared between the instruments. In addition, the best parameters for the AUC were compared between the cpRNFL parameters and macular parameters in each instrument.
  
  
  RESULTS
  These analyses revealed similar AUCs for the average cpRNFL and GCC thicknesses between the instruments. RTVue displayed a significantly higher AUC in the nasal cpRNFL thickness than both Cirrus (P = 0.0004) and 3D OCT (P = 0.0006). 3D OCT showed higher AUCs than Cirrus in the mRNFL parameters. There were no significant differences between the best cpRNFL parameters and macular parameters in each instrument.
  
  
  CONCLUSIONS
  The average cpRNFL and GCC thicknesses that were measured using these OCT instruments exhibited similar abilities for diagnosing highly myopic glaucoma, and RTVue exhibited better diagnostic abilities than Cirrus and 3D OCT for nasal cpRNFL. 3D OCT had better ability than Cirrus in the mRNFL. Both cpRNFL and GCC in each instrument were comparable, and their measurements offered good ability for diagnosing glaucoma with high myopia. (http://www.umin.ac.jp/ctr/index/htm9, UMIN000006900.).
