ABSTRACT
The psychological, psychophysiological, and neurological literature has long since taken note of the intimate relationship that exists between visual perception of objects and their depictions and eye movements. Visual analysis, which consists of a continuous process of singling out the points bearing maximal information and subsequent synthesis of them, requires a system consisting of at least two stimulated points: one on the periphery of the retina, serving as source of the signals that promote further eye motion and have the function of orientation, and the other in the central portion of the retina, accepting and transmitting differentiated visual information. The connection between the narrowing of visual perception to a single element and disturbances in the active analyzing movements involved in centering one's gaze is of fundamental significance to an understanding of the functional structure of visual perception. Neurologically three things were observed in the patient: sluggishness of pupillary response to light with convergence, fundus normal, and visual acuity 1.0 (bilateral).
