PURPOSE A pattern electroretinogram (PERG) simultaneously displaying the frequency-doubling (FD) illusion in nine parts of the visual field was compared with two other methods for ability to detect glaucoma. This multiregion FD PERG (MFP) was compared with results from achromatic automated perimetry and psychophysical tests using FD stimuli. METHODS MFP data were compared with that from the H...

The authors studied the relationship between the critical fusion frequency (CFF) and the threshold value of differential light sensitivity in glaucoma and retinal detachment patients. One hundred and fifty eyes of 82 glaucoma patients and 27 eyes of 27 retinal detachment patients were examined by both light-sense perimetry, using the Octopus 201, and flicker perimetry, using the Octopus 1-2-3. ...

Aim: To evaluate the performance on automated perimetry (AP) after listening to a Mozart sonata in normal subjects naive to AP. Methods: 60 naive normal subjects underwent AP (SITA 242). The study group (30 subjects) underwent AP after listening to Mozart’s Sonata for Two Pianos in D Major and the control group (30 subjects) underwent AP without previous exposure to the music. Results: The stud...

PURPOSE To evaluate the learning effect in standard automated perimetry using SITA strategy, central 24-2 program, possible associated factors and spatial distribution in individuals with no perimetry experience. METHODS A total of 55 healthy subjects were submitted to Humphrey perimetry in two different sessions in one day. Reliability and global indices, and threshold sensitivity at each po...

PURPOSE To examine the concordance of the Glaucoma Hemifield Test and other global visual field indexes between two consecutive automated visual field tests. METHODS Normal subjects, subjects with ocular hypertension, and subjects with glaucoma had two automated visual field tests on the Humphrey Field Analyzer. The Glaucoma Hemifield Test results, mean deviation, and corrected pattern standa...

PURPOSE To evaluate the effect of different levels of intraocular stray light on kinetic perimetry findings. METHODS Twenty-five eyes of 25 healthy young participants were examined by automated kinetic perimetry (Octopus 900) using Goldmann stimuli III4e, I4e, I3e, I2e, and I1e. Each stimulus was presented with a velocity of 3°/s at 24 meridians with 15° intervals. Four levels of intraocular ...

In 106 children aged 5-8 years, we determined how much training was needed to stabilize the response strategy prior to actual visual field assessment and we evaluated the reliability and acceptable duration of automated static perimetry (Octopus 2000R). A specially designed familiarization procedure was used to train the children to: (1) gaze at the center of the visual field while paying atten...

AIMS To define the frequency of seeing (FOS) characteristics of the short wavelength (SW) sensitive visual pathway in clinically normal subjects and in diabetic patients with focal SW sensitivity loss. METHODS For clinically normal subjects, FOS was assessed at two retinal locations (4.24 degrees and 9.90 degrees eccentricity) for both white on white (WW) and SW stimulus parameters. Inter-exa...

PURPOSE To evaluate the sensitivity and specificity of machine learning classifiers (MLCs) for glaucoma diagnosis using Spectral Domain OCT (SD-OCT) and standard automated perimetry (SAP). METHODS Observational cross-sectional study. Sixty two glaucoma patients and 48 healthy individuals were included. All patients underwent a complete ophthalmologic examination, achromatic standard automated...

OBJECTIVES To longitudinally evaluate optical coherence tomography (OCT) peripapillary retinal nerve fiber layer thickness measurements and to compare these measurements across time with clinical status and automated perimetry. METHODS Retrospective evaluation of 64 eyes (37 patients) of glaucoma suspects or patients with glaucoma participating in a prospective longitudinal study. All partici...
