It is a diagnostic tool that aids in the detection of visual disturbances caused by changes in the retina, particularly the macula (e.g. macular degeneration, Epiretinal membrane), as well as the optic nerve and the visual pathway to the brain. Amsler grid usually help detecting defects in central 20 degrees of the visual field. [2]
Visual schedules use a series of pictures to communicate a series of activities or the steps of a specific activity. [1] [2] They are often used to help children understand and manage the daily events in their lives. [3] They can be created using pictures, photographs, or written words, depending upon the ability of the child.
The seven basic tools of quality are a fixed set of visual exercises identified as being most helpful in troubleshooting issues related to quality. [1] They are called basic because they are suitable for people with little formal training in statistics and because they can be used to solve the vast majority of quality-related issues.
Circle time in the United States is a less formal program. Childcare centers often have one, two, or three group gatherings a day that are referred to as "Circle Time." During this time, the children sit in a circle (usually on a rug) and the teacher may read a book aloud, lead a sing-along, or engage the children in a discussion.
a black circle represents the start (initial node) of the workflow; an encircled black circle represents the end (final node). Arrows run from the start towards the end and represent the order in which activities happen. Activity diagrams can be regarded as a form of a structured flowchart combined with a traditional data flow diagram.
The meridian of the visual field has been found to influence the folding of the cerebral cortex. In both the V1 and V2 areas of macaques and humans the vertical meridian of their visual field tends to be represented on the cerebral cortex's convex gyri folds whereas the horizontal meridian is tends to be represented in their concave sulci folds ...

Perimetry or campimetry is one way to systematically test the visual field. [1] [failed verification] It is the systematic measurement of differential light sensitivity in the visual field by the detection of the presence of test targets on a defined background. Perimetry more carefully maps and quantifies the visual field, especially at the ...
