Clinical Significance of Optic Disc Progression by Topographic Change Analysis Maps in Glaucoma: An 8-Year Follow-Up Study
Figure 4
Case examples of disagreement for detecting glaucoma progression among Topographic Change Analysis (TCA) map, optic nerve head (ONH) stereophotographs (SPGs), and Visual Fields (VFs). (a) Low tension glaucoma (LTG), OD, female. This eye was TCA-stable at recruitment (2001). During the prospective followup it remained stable on both TCA and VF. Progression was found only on SPG (increased cupping and inferior rim thinning). (b) Primary open angle glaucoma (POAG), OD, female. This eye was TCA-stable at recruitment (2001). During the prospective followup it remained stable on both TCA and SPG. Progression was found only on VF. (c) POAG, OD, female. This eye was TCA-progressed at recruitment (2000). During the prospective followup it remained stable on both VF and SPG. TCA showed progression (superior and inferior rim thinning) throughout the study period.
