OBJECTIVE: To study the presentation of frequency doubling perimetry (FDP) in patients with primary open-angle glaucoma (POAG). METHODS: Thirty-five cases (37 eyes) of early glaucoma, 36 cases (43 eyes) of advanced glaucoma, 6 cases (7 eyes) of late glaucoma and 21 cases (25 eyes) of normal subjects were examined by FDP with N-30 program and HFA with central threshold 30-2 program. RESULTS: Most eyes with early POAG showed relative paracentral scotoma and/or relative arcuate scotoma. Visual field defects were more likely distributed in superior or nasal areas in the early stage of POAG. The relative scotoma by FDP was almost consistent with that by HFA, but the area of the scotoma was more extensive than that of HFA. In some early POAG, local scotoma which might be missed by HFA could be found by FDP. There was significant difference in the visual indices (FMS, FMD and FPSD) of FDP between normal eyes and early glaucomatous eyes. A significant correlation was found between FMD from FDP and MD from HFA (r = 0.326, P = 0.026). CONCLUSION: There is a good correlativity between FDP and HFA in the diagnosis of early POAG. FDP is a fast and sensitive method of visual field testing in patients with POAG. LA: Chinese
