Automated perimetry, a vision test that is likely performed thousands of times a day within the Unites States alone, has been conducted largely unchanged for several decades. It is also true that many of the fundamental parameters of this form of testing were adopted wholesale from manual kinetic perimetry. Research is now emerging, which suggests that many aspects of automated perimetry, from ...

PURPOSE In order to automate fundus perimetry, which is usually laborious because of the many manual operations and the frequent eye movements, we developed a new fundus perimeter with an automated measuring system using computer technology. METHODS This fundus perimeter consists of an infrared fundus camera, a fundus-pursuit unit, and a target-display unit. Both units are personal computers ...

PURPOSE To investigate the relationship between morphological changes of the optic nerve head (ONH) and macular sensitivity determined with blue on yellow (B on Y) and white on white (W on W) perimetry in normal subjects and patients with glaucoma. METHODS One randomly chosen eye was evaluated in each of 28 healthy subjects, 23 patients with ocular hypertension (OH), and 23 patients with earl...

Using a modified Humphrey perimeter, we evaluated 16 eyes with primary open-angle glaucoma and visual field loss (defects 0.5-3.0 log units in depth), and 14 normal eyes. Each eye was tested twice in random order with conventional luminance-increment static perimetry and with the perimeter modified to produce a high-luminance yellow adapting background and a blue test stimulus. The background w...

The treatment of patients suffering from cerebral blindness following stroke is a topic of much recent interest. Several types of treatment are under investigation, such as substitution with prisms and compensation training of saccades. A third approach, aimed at vision restitution is controversial, as a proper controlled study design is missing. In the current study, 27 chronic stroke patients...

PURPOSE We compared the results of flicker-defined form (FDF) perimetry with standard automated perimetry (SAP) and retinal nerve fiber layer (RNFL) thickness measurements using spectral domain optical coherence tomography (OCT). METHODS A total of 64 healthy subjects, 45 ocular hypertensive patients, and 97 "early" open-angle glaucoma (OAG) patients participated in this study. Definition of ...

PURPOSE Visual field defects and changes in the optic nerve head are signs of glaucoma. It has been shown that blue-on-yellow (B-Y) perimetry can reveal visual field defects earlier and shows them larger than does white-on-white (W-W) perimetry. The Heidelberg retina tomograph (HRT) can produce three-dimensional images of the optic disc. The aim of this study was to find out how B-Y perimetry r...

PURPOSE To compare the detectability between glaucomatous visual field changes using standard automated perimetry (SAP), frequency doubling technology (FDT), short-wavelength automated perimetry (SWAP), and flicker perimetry and structural changes using optical coherence tomography (OCT). PARTICIPANTS Fifty-nine eyes of fifty-nine patients with open-angle glaucoma, 24 eyes of 24 glaucoma susp...

A 68-year-old woman with bilateral idiopathic optic neuropathy was examined using blue-on-yellow perimetry. Best-corrected visual acuity was 0.5 and 0.6 in her right and left eyes, respectively. Visual field testing with a Goldmann perimeter showed constriction of the I/2 e isopter in both eyes. With regard to mean deviation, the results (-13.18 dB right, -10.01 dB left) of blue-on-yellow perim...
