This study tests the hypothesis that abnormal motion displacement thresholds coexist with scotomas on a finer spatial scale than is measurable by conventional Humphrey perimetry. Eighteen patients with primary open angle glaucoma in one eye, and 18 age matched normal controls underwent motion displacement threshold testing and high spatial resolution perimetry. The motion displacement threshold...

IMPORTANCE While standard automated perimetry (SAP) remains the reference standard for evaluation of visual field (VF) defects in glaucoma, this study demonstrates that frequency-doubling technology (FDT) perimetry is effective in monitoring visual field progression and may detect the onset of visual field defects earlier than SAP. OBJECTIVES To compare detection of the development of VF defe...

OBJECTIVES Psoriasis is a hyperproliferative chronic inflammatory skin disease of unknown etiology and ocular structures and visual pathways can also be affected during the course of this disease. Subclinical optic neuritis has previously been observed in psoriatic patients in visual evoked potential studies. This trial was designed to evaluate retinal sensitivity in patients with psoriasis vul...

OBJECTIVE To determine the sensitivity and specificity of scanning laser entoptic perimetry for detecting visual function damage due to age-related macular degeneration (ARMD). METHODS We measured the presence or absence of visual field disturbances by entoptic perimetry and determined the severity of ARMD based on masked readings of fundus photographs. A prospective masked study comparing th...

PURPOSE To test the agreement and correlation between the frequency doubling technology and the short wavelength perimetry in glaucoma. METHODS Glaucoma patients were selected from the Glaucoma Sector of CEROF - Universidade Federal de Goiás, and then underwent frequency doubling technology and short wavelength perimetry examinations in both eyes (if eligible) on the same day in a random sequ...

OBJECTIVE To determine if motion automated perimetry can identify early glaucomatous visual field defects in patients with suspected glaucoma (by disc), those with ocular hypertension, and those with primary open-angle glaucoma. METHODS Motion automated perimetry, a foveally centered motion test, and standard visual field tests were conducted on one randomly selected eye of normal patients (n...

PURPOSE Several visual field defects can be seen in empty sella syndrome (ESS). In this study, the authors aimed to evaluate the visual field defects in patients with ESS by rarebit perimetry and to compare the results with Humphrey perimetry. METHODS Left eyes of 13 patients with ESS and left eyes of 15 age-matched normal subjects were included in the study. Visual field testing was performe...

OBJECTIVES Normal thresholds on Pulsar perimetry fall faster than those of standard perimetry in the peripheral visual field. Two related studies were performed. Firstly, the frequency distributions of glaucoma defects on standard automated perimetry (SAP) and the relationship of the centre and periphery (Study A) were studied first, followed by an attempt to establish the limits of pulsar peri...

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...

BACKGROUND We have developed a binocular perimetry technique for the quantitative assessment of retinal photoreceptor displacement and metamorphopsia. OBJECTIVE To study the direction and amplitude of retinal photoreceptor displacement in eyes with idiopathic macular holes using our binocular perimetry technique. SUBJECTS Five healthy control subjects and 10 patients with unilateral stage 3...
