WebMar 27, 2024 · Optic neuropathy was more prevalent for a prescribed dose of >50 Gy than <50 Gy. We observed a higher prevalence rate for retinopathy (6.0%) than optic neuropathy (2.0%). Insufficient data on the dose for organs at risk were reported. Conclusion: The prevalence of radiation retinopathy was higher compared to optic neuropathy. This review ...
WebThe aim of this study was to develop and evaluate fiber-optic sensors for the remote detection of gamma rays in areas that are difficult to access, such as a spent fuel pool. The fiber-optic sensor consists of a light-generating probe, such as scintillators for radiation detection, plastic optical fibers, and light-measuring devices, such as PMT. The … WebThe optic radiation or geniculocalcarine tract arises from the lateral geniculate body, passes through the retrolenticular portion of the internal capsule and ends in the calcarine cortex located on the medial surface of the occipital lobe.

WebThe optic radiation, also known as the Gratiolet radiation, extended from the lateral geniculate body to the calcarine fissure. The average distance from the tip of the anterior Meyer loop to the calcarine sulcus was 105 mm (range 95–114 mm). The breadth of the optic radiations, one on each side of the brain, averaged 17 mm at the level of ...
WebMar 31, 2024 · Anatomy. The optic nerve is mainly made up of the axons (nerve fibers) of the retinal ganglion cells from the retina. The optic disc or nerve head is the point where the axons from the retinal ganglion cells leave the eye. The nerve head appears as a white circular structure in the back of the eye. There are no photoreceptors on this structure. incontinence thyroidWebDec 16, 2024 · The optic nerve (CN II) is the second cranial nerve, responsible for transmitting the special sensory information for vision.
