Physiology of visual acuity Human visual acuity depends on several sizes: Physically the size of the pupil limits the resolution of the eyeball, physiologically the resolution is determined by the density of the receptors (rods and cones) and the signal processing of the receptive fields of the retina. The resolution reaches its maximum value when … Physiology of visual acuity | The visual acuity
Definition Visual acuity (visual acuity, visual acuity, minimum separable) indicates the measurable degree of ability to recognize patterns and contours in the outside world as such. Minimum visibile Minimum visibile is the limit of visibility. This is reached when objects that are viewed and imaged on the retina can no longer be distinguished as contour … The visual acuity
Introduction The visual pathway is a part of the brain, because all its components originate there, including the optic nerve. The visual pathway begins at the retina, whose ganglion cells are the starting point, and ends in the visual cortex in the cerebrum. Its complex structure enables us to see. Anatomy of the visual path … Visual path
Course of the visual path The visual pathway extends from the retina of the eye to various areas of the brain. The most distant area of the brain is located at the back wall of the skull and thus at the head on the opposite side of the eyes. The beginning of the visual path … Course of the visual path | Visual path
Insertion of the visual field The retinal sections reflect the visual fields in opposite arrangement. The right part of the visual field of each eye is recorded on the left side of the retina. The left halves of the visual fields are accordingly imaged on the right part of the retina.The right and left tractus … Insertion of the visual field | Visual path
What is Chiasma Syndrome? Chiasma syndrome consists of three components and occurs when the intersection of the visual pathways along the midline is damaged. This results in a conduction disorder of the central parts of the retina and the field of vision of the outer sides of both eyes is no longer perceived. In addition, … What is Chiasma Syndrome? | Visual path
