OBJECTIVES To present and evaluate a new combined index of structure and function (CSFI) for staging and detecting glaucomatous damage. METHODS Observational study including 333 glaucomatous eyes (295 with perimetric glaucoma and 38 with preperimetric glaucoma) and 330 eyes of healthy subjects.All the eyes were tested with standard automated perimetry and spectral domain optical coherence tom...

AIM To evaluate the learning effect of Frequency Doubling Technology (FDT) perimetry using the Humphrey Matrix-FDT perimetry (Matrix) 24-2 full-threshold program on patients with ocular hypertension experienced with standard automated perimetry. METHODS Twenty-four patients with ocular hypertension underwent 5 full-threshold Matrix tests at intervals of 5+/-2 days. Learning effect was defined...

BACKGROUND Frequency doubling technology (FDT) perimetry measures contrast sensitivity. The magnocellular component of ganglion cells in human retina is isolated as a whole by the FDT stimulus. The aim of this study is to investigate the role of Humphrey Matrix threshold testing in the detection of early functional retinal impairment in ocular hypertensive patients compared to standard automate...

OBJECTIVE To compare examination time and visual field loss for ptosis fields obtained with manual kinetic (Goldmann) perimetry and automated static (Humphrey) perimetry. METHODS Both eyes of 12 patients with bilateral aponeurogenic ptosis were prospectively examined using Goldmann and Humphrey (ptosis protocol) perimetry with the eyelids ptotic and taped into a normal position. RESULTS Bil...

PURPOSE A significant variability of the second harmonic (2ndH) phase of steady-state pattern electroretinogram (SS-PERG) in intrasession retest has been recently described in glaucoma patients (GP), which has not been found in healthy subjects. To evaluate the reliability of phase variability in retest (a procedure called RE-PERG or REPERG) in the presence of cataract, which is known to affect...

OBJECTIVE To assess the potential role of Swedish Interactive Thresholding Algorithm (SITA) Fast computerized static perimetry, compared with that of Goldmann manual kinetic perimetry (GVF), for reliably detecting visual field defects in neuro-ophthalmic practice. BACKGROUND Automated visual field testing is challenging in patients with poor visual acuity or severe neurological disease. In th...
