Nasal part of the retina
WitrynaThe retinal microvasculature pattern was related to clinical and biochemical parameters. Results: Patients with diabetes exhibited larger venule diameters in the upper temporal quadrant of the retina compared to the lower temporal quadrant (124.85±38.03 µm vs 102.92±15.69 µm; P< 0.01). Patients with diabetes for 5 or more years had larger ...

WitrynaThe optic nerve head shows a pale appearance, and in the depicted nasal part of the retina the typical intraretinal distribution of pigment (bone spicule pigmentation) is marked. Note the atrophic aspect of the retina as a whole. The classification of RP is based upon the mode of inheritance. The last decade has witnessed a rapidly growing ... WitrynaThe GCC measurements listed are for his left eye only; the affected visual field category is the average of the affected hemifield in the right and left eyes; there are two separate RNFL calculations, ie, nasal affected versus nasal unaffected: mean 74.1±19.49 μm versus 74.1±18.96 μm; P=0.99; and combined T/S/I affected versus unaffected ...

There are no photoreceptors (i.e., rods or cones) in … 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.
WitrynaDamage to the retina or one of the optic nerves before it reaches the chiasm results in a loss of vision that is limited to the eye of origin. In contrast, damage in the region of the optic chiasm—or more … WitrynaOne of the most useful RNFL displays in clinical practice is the sinusoidal profile wave corresponding to the RNFL thickness profile 360 degrees around the optic nerve, …
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) …
WitrynaThe prominent nasal part of the optic disc appears less ‘blind’ than the shallow temporal part, probably because of more intensive light scattering by the prominent nasal part of the disc. ...

The results imply that artificial manipulation of the circadian pacemaker to alleviate jet lag, to improve alertness in shift workers, and ... my.cornercard chWitrynaAbstract. In normal eyes, the retinal nerve fiber layer (RNFL) is usually best visible in the inferior temporal part of the fundus, followed by the superior temporal region, the nasal superior region and the nasal inferior region.
