WebJan 23, 2006 · It is defined as a retinocerebral apparatus engaged in elaborating a sensation in response to excitation of a unit area of retinal surface. The retinal area when stimulated by light entering the eye from an object is perceived not only as being of certain brightness, color and certain form, but also has a certain direction in visual space. WebA 670-nm diode laser emits a beam that is focused in the x-axis and y-axis (horizontal and vertical dimensions) of the ONH, perpendicular to the z-axis (axis along the optic nerve). The reflected image from this plane is captured as a 2-dimensional scan. Successive equidistant images are obtained, up to 64 in total, depending on the cup depth.
