Abstract
Purpose: To compare the frequency doubling technology perimeter (FDT) with retinal nerve fiber layer (RNFL) photography as a tool for the early detection of glaucoma. Methods: Ninety-eight eyes of 98 patients were evaluated over a period of 3 months. According to the results of RNFL photography and FDT, Patients were divided into four groups based on the results of RNFL photography and optical coherence tomography (OCT). A comparison of the RNFL thickness of each group was performed using the OCT results. Results: RNFL thickness in the group with abnormal FDT and normal RNFL were significantly decreased from those in the group with normal FDT and RNFL photography at the 6, 7 and, 10 o’clock area (p
