“…In their paper, the mean values of changes in size of tubular fields were calculated to be small, because in their calculation, increasing values were counteracted by decreasing ones. In fact, their 16 cases included stable cases and variable cases, and the latter showed a variation from -7 ° to + 14 ° [2]. Thus, poor reproducibility in visual field seems to be one of characteristics in patients with hysteria.…”

“…The diagnosis of psychogenic visual disturbance is based on 1. visual deterioration without organic lesion; and 2. environmental factor inducing visual disturbance, for example, problems in school or home and conflicts with parents are common [1][2][3][4][5][6]. Examinations of dark adaptation [5,6], VER [6], and visual field [1][2][3][4] are known to be helpful for diagnosis.…”

“…Examinations of dark adaptation [5,6], VER [6], and visual field [1][2][3][4] are known to be helpful for diagnosis. Tubular field seems to be a specific finding in hysteria [1][2][3][4]. However it was difficult to reveal a tubular field in our patients.…”

“…Spiral and star-shaped field mean poor reproducibility, and the variability in shape of visual field is pointed out as one of characteristic findings in hysteria [3]. On the other hand, Schlaegel and Quilala [2] pointed out that the size of the tubular fields were rather constant on successive examinations. In their paper, the mean values of changes in size of tubular fields were calculated to be small, because in their calculation, increasing values were counteracted by decreasing ones.…”

“…It has been well known that visual field abnormalities, namely, concentric contraction, tubular, spiral, and star-shaped visual fields are useful for the diagnosis of hysteria [1][2][3][4]. It is pointed out that the shape of visual field varies between successive examinations in patients with hysteria [3].…”

Four cases with hysterical amblyopia in youngsters under 15-year-old showed the poor reproducibility of visual field, that is, when the same target was moved from the periphery toward the fixation ten times along the same meridian during the same examination, the position of the plotted points were rather variable. The range of variation was measured from the innermost point to the outermost one, after the two first points were omitted because points first detected were usually far from the others. The variation of cases measured by this method was compared with that of normal persons. Results were as follows; 1. in normal person, the mean value of its range was 5.5 degrees in first decade and 4.2 degrees in second to seventh decade; 2. patients with psychogenic visual disturbances showed a variability of 14.2 degrees, and this was significantly different from normal (p less than 0.01). These results suggest that this convenient method was helpful for diagnosis of hysteria. It should also be remembered that when we evaluate the visual field, changes under 4 degrees are probably not significant.
