Abstract

A new method for evaluating the total (BINOCULAR) field is based on FUNCTION instead of on anatomy. According to the author's theory of relative values, certain areas of the field are functionally more important than others in human activity. The new system imitates nature by plotting the total field binocularly instead of combining the two conventional monocular fields. Scoring is then done by a new binocular grid—a relative value scale, weighted exactly like its monocular prototype to favor the functionally more valuable parts of the field. The new method also led to the discovery of “binocular enhancement” that produces scores more realistic than formerly possible. Especially useful to ophthalmic consultants for evaluating visual capability or disability in industry, law and government (workers compensation, motor vehicle, social security, aviation, military), the new scale works accurately and rapidly with most existing perimeters, manual or automated.

Characterization of visual scanning while driving for the identification of drivers’ profiles
2021, Transportation Research Part F: Traffic Psychology and Behaviour
Assessing the driving skills of people with cognitive or visual impairments is often complex. The analysis of visual exploration strategies can be a good solution to identify the implementation or not of good strategies of information search in the visual scene (adaptation and compensation). In this study, we compared the visual exploration behaviours of 26 healthy, 19 glaucoma and 21 elderly participants. For this purpose, we used a driving simulator for which a visual field measurement test had been adapted to obtain measurements in static and dynamic conditions. The dynamics of the gaze was also measured. Our results showed that each of the three groups of participants had specific characteristics of visual exploration. Using a classification algorithm, we were able to show that it was possible to identify the group which a participant belonged to on the basis of the visual exploration’s characteristics. This finding opens the door to many applications in the context of driving assistance and training.
Comparison between elderly and young drivers’ performances on a driving simulator and self-assessment of their driving attitudes and mastery

The points, displayed successively, were defined by their angular coordinates with respect to the central fixation point. The grid consisted of 104 points, corresponding to the 85 points of the Esterman (1982) grid, plus a further 19 points in the central zone (Fig. 2). This scenario made it possible to characterize the participant's static visual field deficit.
Elderly people are often considered dangerous drivers due to a decline in visual exploration and cognitive functions. The purpose of this study was to look into 18 young (between 21 and 35  years old) and 12 elderly (between 65 and 78 years old) drivers’ behaviour. We compared their self-assessment of driving as well as their visual and cognitive competencies. Then we assessed their driving competencies and self-regulation practices by using different scenarios on a driving simulator. These scenarios were designed to test drivers in situations that were intended to solicit the cognitive competencies identified as problematic for elderly drivers (attention, executive functions: anticipation, planning, mental flexibility). Results showed that, although elderly drivers did not always perform as well as young drivers, they could put in place compensatory strategies which may reduce their risk of being injured and future research should explore ways of enhancing those strategies. In particular, more should be done in order to strengthen elderly’s understanding regarding their driving difficulties and help them set up coping methods with respect to these difficulties.
Functional assessment of glaucoma: Uncovering progression

Assessing visual field progression using binocular visual field assessments may therefore be desirable. The Esterman test is a suprathreshold test taken with both eyes open that provides an assessment of the binocular visual field.50 The Esterman test is typically performed to determine whether patients meet the vision standard required for driving and is rarely performed in clinical settings to monitor ocular conditions.
Clinicians who manage glaucoma patients carefully monitor the visual field to determine if treatments are effective or interventions are needed. Visual field tests may reflect disease progression or variability among examinations. We describe the approaches and perimetric tests used to evaluate glaucomatous visual field progression and factors that are important for identifying progression. These include stimulus size, which area of the visual field to assess (central versus peripheral), and the testing frequency, evaluating which is important to detect change early while minimizing patient testing burden. We also review the different statistical methods developed to identify change. These include trend- and event-based analyses, parametric and nonparametric tests, population-based versus individualized approaches, as well as pointwise and global analyses. We hope this information will prove useful and important to enhance the management of glaucoma patients. Overall, analysis procedures based on series of at least 5 to 6 examinations that require confirmation and persistence of changes, that are guided by the pattern and shape of the glaucomatous visual field deficits, and that are consistent with structural defects provide the best clinical performance.
