WitrynaThe optic disc in a normal human eye carries 1–1.2 million afferent nerve fibers from the eye towards the brain. Structure [ edit] The optic disc is placed 3 to 4 mm to the nasal side of the fovea. It is a vertical oval, with average dimensions of 1.76mm horizontally by 1.92mm vertically. [2] WitrynaThe optic nerve from each eye meets at the optic chiasm, at which point axons from the nasal part of the retina cross over to the other side of the brain, whereas axons from the temporal retina ...

Witryna1 mar 2024 · How does the nasal retina relate to the temporal retina? Because light reaches the retina through a lens, the light received from the temporal half of the visual field falls upon the nasal parts of each retina, and vice versa. Fibers from the nasal and temporal retina travel together in the optic nerve, but are separated at the chiasm. Witryna14 kwi 2024 · Crossing nerve fibers of the optic chiasm are linked to nerve fibers from the nasal side of the retina. Compression of the optic chiasm is thought to cause retrograde degeneration of the nerves on the nasal side of the retina, resulting in thinning. ... it is inconclusive which part of the retinal nerve layer (e.g., pRNFL or mGCC) …

WitrynaCT was assessed manually from the retinal pigment epithelium to the inner face of the sclera, in the inferior, superior, nasal, and temporal quadrants. Two clinicians (BO and SK), who were masked to clinical patient data, measured the CT in all subjects and the mean value of the measurements was calculated. WitrynaThe neural retina consists of several layers of neurons interconnected by synapses and is supported by an outer layer of pigmented epithelial cells. The primary light-sensing cells in the retina are the photoreceptor …

WitrynaThe image from each temporal visual field (nasal retina) crosses in the chiasm to continue as an optic tract on the opposite side of the brain.

Impairment of autoregulation in the retinal circulation has also been implicated in the pathogenesis of various retinal diseases, including diabetic retinopathy and diabetic macular edema.
