Jerome Sherman, OD, FAAO Jerome Sherman, O.D., is perhaps optometry's most prolific writer, publishing over 650 clinical articles, research manuscripts, book chapters and two CDs. He is senior author of three books that were published in 2007, and has delivered over three thousand lectures both nationally and internationally. He has served as a contributing

Comments and Conclusions Although the majority of clinically encountered optic nerve disorders are due to glaucoma, other etiologies are possible. The GCC is a novel way to document loss of the ganglion cells and their related axons and dendrites. The iWellness Exam furnishes GCC data as well as cross sections of the retina. The VEP

Case 6: Comparison of GCC and Visual Field In this case, the GCC, OCT and GDx OS reveal far more impressive abnormalities than does the visual field. In glaucoma, the GCC, OCT and GDx often "predict" a future field loss.

Case 6: Comparison of GCC and OCT/GDx RNFL The GCC, OCT and GDx appear normal in the OD. In contrast, the GCC, OCT and GDx are all abnormal superiorly in the OS. Central corneal thickness is quite normal at about 555um OU. Since the patient never had Goldmann IOPs higher than 16 and the cups

Case 6: Optovue iWellness Exam OU A 54-year-old black female. Goldmann IOPs were 12mmHg OD and 13mmHg OS & DVA 20/25+1 OD, 20/40 OS. The iWellness Exam revealed profound thinning in the superior half of the GCC donut OS.

Case 5: Comparison of GCC and Visual Fields The GCC in the R.E. is nearly normal but does appear to exhibit some thinning inferior temporal to the fovea. This corresponds to the subtle superior nasal reduction in sensitivity at one point (circles). The GCC in the L.E. is quite thin inferior temporal to the
