In autumn, a slight return of beetles and isopters in the menu of the hedgehog but the hymenoptera remain the most preponderant in the feeding of this animal.
Visual field improvement was defined as an improvement of the field defect by at least 10[degrees] horizontally and 15[degrees] vertically using similar isopters on the Goldman visual fields and significant changes in mean and pattern deviations in Humphrey visual fields.
John's peripheral visual fields were plotted using Goldmann visual field equipment (see Figure 1 for the left eye and Figure 2 for the fight eye) with 14e and 12e isopters.
Goldmann perimetry employs primarily a kinetic technique to plot boundaries of isopters (points joined together by a drawn line with equal levels of estimated sensitivity) and scotomas (depressed areas of sensitivity) by moving a visual stimulus from a non-seeing to a seeing region.
Generally the blind spot position/size and at least three isopters are presented, having been selected to demonstrate the location, depth and extent of any significant variation in the visual field.
The horizontal field extent was assessed by superimposing the Goldmann III4 isopters for both eyes separately.
Studies on the effects of age on the central and peripheral isopters of the visual field in normal subjects.
