Awesome video stapsell. Hey curry, I believe it's because of refraction when light passes through the lens to be directed towards the retina's macula lutea. The light is inverted and switch to contralateral side.
the nasal retinal fibres correspond to the temporal field of view. Just think about light entering the eye being the same as a pinhole camera, with the retina being the film in the camera. similarly the light from the upper field of view is detected by the lower retina. A superior retinal detachment causes loss of the inferior field of vision in the affected eye.
If the optic chiasm is the site where the nasal retinal fibres cross over, why is it that a lesion in the optic chiasm results in loss of vision in the temporal region rather than the nasal?
@currycurry14 The nasal retina receives visual information from the temporal sides, and the temporal retina receives visual information from the nasal side.
Very nice video and voice over! Thanks...USA med dr in training.

It does explain as to why I had Left Temporal Lobe surgery and lost just a tad bit of loss in my top right corner eye sight.
