Objective To determine the difference of global indices of retinal thickness at posterior pole in primary and suspected glaucoma. Methods Forty-five global indices of analysis on retinal thickness at posterior pole in every case, including 12 cases of primary open-angle glaucoma and 11 cases of suspected glaucoma were obtained by advanced retinal thickness analyzer. Every index was also compared. Results There were significant differences between primary and suspected glaucoma in foveal shape deviation (FSD), foveal corrected thickness deviation (FCTD), foveal fixation corrected thickness deviation (FFD), foveola thickness deviation (VTD), corrected foveola thickness deviation (CVTD), peri-foveal abnormally thin area (PFATN), posterior-pole pattern deviation (PPPD), and posterior-pole abnormally thin area (PPATN). Conclusion There are significant difference of morphologic indices of retinal thickness at posterior pole between primary and suspected glaucoma. (Chin J Ocul Fundus Dis, 2002, 18: 113-115)
