PURPOSE: To evaluate the correlation between visual field index (VFI) and both structural and functional measures of the optic disc in primary open angle glaucoma patients and suspects. METHODS: In this retrospective study, 162 glaucoma patients and suspects underwent standard automated perimetry (SAP), retinography, and retinal nerve fiber layer (RNFL) measurement. The optic disc was stratified according to the vertical cup/disc ratio (C/D) and sorted by the disc damage likelihood scale (DDLS)...

BACKGROUND: We assessed bleb morphology and the intraocular pressure (IOP)-lowering effect of trabeculectomy with ologen compared to mitomycin C (MMC) in juvenile open-angle glaucoma (JOAG). METHODS: This is a prospective interventional comparative study conducted on 40 eyes (20 patients) with medically uncontrolled JOAG, randomly operating one eye for trabeculectomy with ologen (group A: 20 eyes) and the other with MMC (group B: 20 eyes). IOP measurement, SITA standard perimetry, and spectral domain optical coherence tomography (OCT) for retinal nerve fiber layer (RNFL) thickness were all done pre- and postoperatively...

AIM: to study the frequency of misdiagnosis of cataract in patients with optic nerve pathology or amblyopia and to identify its main causes. MATERIAL AND METHODS: The study enrolled 381 patients (381 eyes) wrongly diagnosed with cataract. A standard set of eye tests was performed. In-depth examination of the macular area was done through biomicroscopy with contactless aspheric lenses of 60 and 90 D. Part of the patients underwent optical coherence tomography and static perimetry as well as examination of electrical sensitivity threshold and electrical lability of the optic nerve...

Objective: To investigate the rationality of visual field morphological stages of glaucoma, its relationship with visual field index and their diagnostic value. Methods: Retrospective series case study. Two hundred and seventy-four glaucoma patients and 100 normal control received visual field examination by Humphrey perimeter using standard automatic perimetry (SAP) program from March 2014 to September 2014. Glaucoma patients were graded into four stages according to characteristic morphological damage of visual field, distribution of mean defect (MD) and visual field index (VFI) of each stage were plotted and receiver operation characteristic curve (ROC) was used to explore its correlation with MD and VFI...

A woman aged 26 years was referred by her GP to the eye casualty department with sudden-onset left homonymous hemianopia and right-sided headache. Full ophthalmic examination was normal with the exception of a left homonymous hemianopia confirmed with automated perimetry. Urgent CT imaging revealed a non-haemorrhagic cerebral infarct in the right parieto-occipital region. Subsequent blood tests confirmed a diagnosis of antiphospholipid syndrome with positivity in IgG anticardiolipin antibody, IgG anti-β2-GP1 antibody and the Lupus anticoagulant screen...

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 standard PERG, we tested this procedure in GP, normal controls (NC), and cataract patients (CP)...

PURPOSE: To determine the relationship between the rate of glaucomatous visual field loss and the amplitude of a 24-h intraocular pressure (IOP)-related profile measured using a contact lens sensor (CLS). METHODS: This observational study included 22 patients with glaucoma and an IOP of consistently ≤21 mm Hg during office hours. All subjects underwent Goldmann tonometry, standard automated perimetry (SAP), dilated fundus examination, and had a CLS recording. A cosine function was used to obtain peak (acrophase), trough (bathyphase), and amplitude measurements...

PURPOSE OF THE STUDY: The purpose of the study was to investigate the relationship between optical coherence tomography angiography angioflow vessel-density (PAFD) measured in the retinal nerve fiber layer in the temporal peripapillary sector and the average of the spatially corresponding superior and inferior paracentral cluster mean defect values (mean paracentral MD) measured with Octopus perimetry. MATERIALS AND METHODS: Spaerman's correlation between temporal peripapillary PAFD acquired with the Angiovue OCT and mean paracentral MD measured with the Normal and tendency-oriented perimetry strategy of Octopus G2 perimetry, respectively, was determined on 1 eye of 13 healthy participants, 22 medically controlled ocular hypertensive, and 27 stable early to moderate glaucoma patients...

Purpose: Peripheral vision is important for mobility, balance, and guidance of attention, but standard perimetry examines only <20% of the entire visual field. We report on the relation between central and peripheral visual field damage, and on retest variability, with a simple approach for automated kinetic perimetry (AKP) of the peripheral field. Methods: Thirty patients with glaucoma (median age 68, range 59-83 years; median Mean Deviation -8.0, range -16...

REVIEW
Jane W Chan
Since obesity has become an epidemic in industrialized nations, idiopathic intracranial hypertension (IIH) is now a more common neuro-ophthalmic disorder that causes visual loss and headaches. This review highlights the new diagnostic criteria for IIH and the new insights into the pathophysiologic mechanisms of IIH. Key diagnostic and monitoring techniques for papilledema include not only neuroimaging and the measurement of cerebrospinal fluid (CSF) pressure, but also perimetry, optical coherence tomography, and ocular sonography...

PURPOSE: The aim of this study was to compare the predictive value of retinal nerve fiber layer thickness (RNFLT) measurements obtained by optical coherence tomography (OCT), morphometric parameters of confocal scanning laser ophthalmoscopy (CSLO), and frequency-doubling technique perimetry to predict visual field conversion of normal individuals, ocular hypertensive subjects, and early preperimetric glaucoma patients as determined by standard automated perimetry (SAP). PATIENTS AND METHODS: This longitudinal single-center study included 107 eyes of 56 controls, 164 eyes of 98 patients with ocular hypertension, and 169 eyes of 110 patients with preperimetric glaucoma...
