“… 27 – 29 An accelerated loss of the differential luminance sensitivity and spatial resolution was found in older subjects. 30 – 32 A greater influence of the stimulus velocity with increasing age for the central isopters has been reported. 33 For smaller and dimmer stimuli only, an age-dependence was observed.…”

PurposeTo determine normal values of the visual field (VF), corrected for age and reaction time (RT) for semiautomated kinetic perimetry (SKP) on the Octopus 900 perimeter, create a model describing the age-dependency of these values, and assess test–retest reliability for each isopter.MethodsEighty-six eyes of 86 ophthalmologically healthy subjects (age 11–79 years, 34 males, 52 females) underwent full-field kinetic perimetry with the Octopus 900 instrument. Stimulus size, luminance, velocity, meridional angle, subject age, and their interactions, were used to create a smooth multiple regression mathematical model (V/4e, III/4e, I/4e, I/3e, I/2e, I/1e, and I/1a isopters). Fourteen subjects (2 from each of 7 age groups) were evaluated on three separate sessions to assess test–retest reliability of the isopters. Reaction time (RT) was tested by presenting 12 designated RT-vectors between 10° and 20° within the seeing areas for the III/4e isopter (stimulus velocity, 3°/second). Four RT- vectors were presented at the nasal (0° or 180°), superotemporal (45°), and inferior (270°) meridians.ResultsThe model fit was excellent (r2 = 0.94). The test–retest variability was less than 5°, and the median decrease in this deviation attributed to aging, per decade, for all age groups and for all stimulus sizes was 0.8°. No significant learning effect was observed for any age group or isopter.ConclusionAge-corrected and RT-corrected normative threshold values for full-field kinetic perimetry can be adequately described by a smooth multiple linear regression mathematical model.Translational RelevanceA description of the entire kinetic VF is useful for assessing a full characterization of VF sensitivity, determining function losses associated with ocular and neurologic diseases, and for providing a more comprehensive analysis of structure–function relationships.

“…The annular stimuli are arranged in a series of rings and have borders 5 cd/m 2 darker and a core 5 cd/m 2 brighter than the background. This modification effectively eliminates low spatial frequency information and creates vanishing optotypes, so the stimulus is not detectable at sizes below the acuity threshold [46]. It is suggested that HRP findings do not indicate RGC density or damage directly, even though they target the high spatial frequency parvocellular pathway [47,48].…”

Visual field (VF) testing dates back to fifth century B.C. It plays a pivotal role in the diagnosis, management, and prognosis of retinal and neurological diseases. This review summarizes each of the different VF tests and perimetric methods, including the advantages and disadvantages and adherence to the desired standard diagnostic criteria. The review targets beginners and eye care professionals and includes history and evolution, qualitative and quantitative tests, and subjective and objective perimetric methods. VF testing methods have evolved in terms of technique, precision, user-friendliness, and accuracy. Consequently, some earlier perimetric techniques, often still effective, are not used or have been forgotten. Newer technologies may not always be advantageous because of higher costs, and they may not achieve the desired sensitivity and specificity. VF testing is most often used in glaucoma and neurological diseases, but new objective methods that also measure response latencies are emerging for the management of retinal diseases. Given the varied perimetric methods available, clinicians are advised to select appropriate methods to suit their needs and target disease and to decide on applying simple vs. complex tests or between using subjective and objective methods. Newer, rapid, non-contact, objective methods may provide improved patient satisfaction and allow for the testing of children and the infirm.

“…[132][133][134][135][136][137][138][139][140][141] HPRP has a number of desirable characteristics, including: (1) a rapid test procedure, (2) interactive communication with the patient, (3) feedback to the patient concerning performance, (4) good ability to detect visual field loss in glaucoma and other ocular and neurologic disorders, (5) ability to determine visual field progression earlier than standard automated perimetry, and (6) an easy to follow test procedure. [132][133][134][135][136][137][138][139][140][141] Unfortunately, the commercial availability of HPRP at the present time is very limited. An example of HPRP conducted for the right eye of a patient with glaucomatous visual field loss is presented in Fig.…”
