The purpose of the current study is to investigate test-retest reproducibility visual fields (VFs) measured with MP-3 microperimeter, in patients retinitis pigmentosa (RP).VFs were twice and also Humphrey Field Analyzer, using 10-2 test grid pattern both perimeters, 30 eyes (15 right 15 left eyes) 18 RP (11 males 7 females). Test-retest was assessed mean absolute deviation (MAD) measure at all 68 points grid. Reproducibility evaluated intraclass correlation coefficient (ICC) VF...
It is important to compare the results of Corneal Visualization Scheimpflug Technology instrument (CST) measurements and Reichert Ocular Response Analyzer (ORA) parameters. The purpose study was investigate association between CST ORA parameters in ninety-five patients with primary open-angle glaucoma. Measurements CST, ORA, axial length (AL), average corneal curvature (CC), central thickness (CCT) intraocular pressure (IOP) Goldmann applanation tonometry (GAT) were carried out. assessed...
Corneal Visualization Scheimpflug Technology (CST) and Ocular Response Analyzer (ORA) measurements were carried out in 105 eyes of 69 patients with primary open-angle glaucoma. All had axial length (AL), central corneal thickness (CCT), intraocular pressure (IOP) Goldmann applanation tonometry (GAT) eight visual fields (VF)s the Humphrey Field Analyzer. VF progression was summarized using a time trend analysis mean total deviation (mTD) association between mTD rate number ocular parameters...
Purpose.: To compare the visual fields (VFs) of preperimetric open angle glaucoma (OAG) patients (preperimetric VFs, PPGVFs) with VFs healthy eyes, and to discriminate these two groups by using Random Forests machine-learning method. Methods.: All before a first diagnosis manifest (Anderson-Patella's criteria) were classified as PPGVFs. Series obtained Humphrey Field Analyzer 30-2 program from 171 PPGVFs 53 eyes in 51 OAG or suspect 108 87 normal subjects. The area under receiver operating...
Purpose.: To develop new visual field (VF) sectors based on pointwise rates of glaucomatous VF progression ("progression regions") and to evaluate their usefulness for predicting future progression. Methods.: A training dataset consisting 10 VFs from each 412 eyes in open-angle glaucoma patients a validation 15 71 45 were investigated. First, using the dataset, was divided into small regions, according all 52 test points VF. Then, initial four total deviation (TD) values 10th predicted by...
To determine the axial length requiring adjustment of measured circumpapillary retinal nerve fiber layer (cpRNFL) thickness to account for ocular magnification during spectral-domain optical coherence tomography (SD-OCT).In this prospective study, 148 eyes healthy student volunteers were imaged by two examiners using three-dimensional SD-OCT. In 54 randomly selected eyes, total cpRNFL was with and without establish intra-examiner inter-examiner measurement error. The then divided into three...
To assess and compare the accuracy of Kang's method for ocular magnification correction in circumpapillary retinal nerve fiber layer (cpRNFL) thickness measurement with that currently used Littmann's method.A total 148 eyes healthy participants underwent cpRNFL without by using spectral-domain optical coherence tomography. Correction is based on observed uncorrected thickness. The was compared Pearson product-moment correlation coefficient (r) Bland-Altman analysis.A 132 were assessed. two...
Purpose: The purpose of this study was to investigate the association between visual acuity (VA) and reproducibility test–retest field (VF) measurements in glaucoma patients. Methods: Subjects were comprised 627 eyes open-angle two Humphrey VFs (24-2 or 30-2 Swedish Interactive Threshold Algorithm tests) examined twice within period 3 months calculated using root mean squared error (RMSE) each VF test point's sensitivity. Visual measured once at time either measurements. Linear modeling used...
<h3>Background/aims</h3> To investigate the usefulness of Octopus (Haag-Streit) EyeSuite's cluster trend analysis in glaucoma. <h3>Methods</h3> Ten visual fields (VFs) with Humphrey Field Analyzer (Carl Zeiss Meditec), spanning 7.7 years on average were obtained from 728 eyes 475 primary open angle glaucoma patients. Mean total deviation (mTD) and performed various series VFs (from 1st to 10th: VF1-10 6th VF6-10). The results cluster-based analysis, based different lengths VF series,...
Purpose: To validate the prediction accuracy of variational Bayes linear regression (VBLR) with two datasets external to training dataset. Method: The dataset consisted 7268 eyes 4278 subjects from University Tokyo Hospital. Japanese Archive Multicentral Databases in Glaucoma (JAMDIG) 271 177 patients, and Diagnostic Innovations Study (DIGS) includes 248 173 which were used for validation. Prediction was compared between VBLR ordinary least squared (OLSLR). First, OLSLR carried out using...
The aim of this cross-sectional study was to evaluate the results a visual field (VF) test for patients with glaucoma and pseudo-fixation loss. These exhibit fixation loss (FL) rates >20% Humphrey Field Analyzer (HFA); however, actual stabilizes when head-mounted perimeter (imo) is used. This device able adjust stimulus presentation point by tracking eye movements. We subjected 54 eyes pseudo-FL HFA 30-2 or 24-2 Swedish Interactive Threshold Algorithm -Standard protocol. All also underwent...
To investigate the association between corneal biomechanical properties measured with Ocular Response Analyzer (ORA) and also CorvisST (CST) tonometry, glaucomatous visual field (VF) severity.One hundred forty-six eyes of 91 patients primary open-angle glaucoma who performed Humphrey Field 30-2 or 24-2 SITA-Standard, ORA, CST within 180 days were included in this multicentral, observational cross-sectional study. The ORA parameters (corneal hysteresis [CH] resistant factor [CRF]), (A1 A2...
Purpose: To evaluate the learning effect and repeatability of automated kinetic perimetry in inexperienced experienced healthy young participants.Methods: Forty-six eyes 46 participants (23 23 group group; mean age, 25.9 years) were enrolled this prospective study. Automated was performed using Octopus 900 perimeter with Goldmann stimuli III4e, I4e, I3e, I2e I1e. The underwent testing at 14 predetermined meridians for each stimulus a velocity 3°/s. evaluated sensitivity test duration three...
AIM: To compare the corneal biomechanical properties difference by ocular response analyzer (ORA) in normal tension glaucoma (NTG) patients with different visual field (VF) progression speed. METHODS: NTG well-controlled Goldmann applanation tonometer (GAT) who routinely consulted Kitasato University Hospital Glaucoma Department between January 2010 and February 2014 were enrolled. GAT ORA parameters including compensated intraocular pressure (IOPcc), estimated (IOPg), hysteresis (CH),...
To construct a new item bank to measure quality of life (QOL) in glaucoma patients and evaluate patients' QOL using the bank.An questions was generated through literature review instruments useful for patients. Using this bank, cognitive survey performed on 203 with (112 males 91 females, 61.9±11.9 y old; mean±SD). The results were then analyzed Rasch analysis, Rasch-derived disability scores predicted linear modelling following clinical parameters: age, mean total deviation (mTD) superior...
