optic disc location nasal or temporal

The most common location for a retinal tear is in the superotemporal quadrant (60%) and because of the effects of gravity results in a greater incidence of macula-off retinal detachment, compared with inferior or nasal retinal tears. Summary. At the chiasm, 53% of the axons from the nasal retina cross the midline to join the uncrossed temporal fibers. To do so they must arc around the papillomacular bundle, forming the appropriately named arcuate fibers. Syphilitic optic neuritis is often associated with ocular inflammation. Since the optic nerve transmits retinal information to the brain, … Drugs.com provides accurate and independent information on more than 24,000 prescription drugs, over-the-counter medicines and natural products. Structures passing through the lateral wall of cavernous sinus. Paired and unpaired dural venous sinuses. (2) Optic atrophy or cortical blindness. The visual system comprises the sensory organ (the eye) and parts of the central nervous system (the retina containing photoreceptor cells, the optic nerve, the optic tract and the visual cortex) which gives organisms the sense of sight (the ability to detect and process visible light) as well as enabling the formation of several non-image photo response functions. (3) Papilledema. Optic disc thinning and cupping. The most common location of a mucocele is the fronto-ethmoidal sinus, followed by the sphenoid sinus. Summary. f. Optic nerve. As part of the bony thorax, the thoracic vertebrae help protect the internal viscera – such as the heart, lungs and oesophagus. The radius is the distance between the centre of the fovea and the temporal margin of the disc.

Paired and unpaired dural venous sinuses. 4. The optic nerves consist of the axons from the retinal ganglion of each eye. Headaches are common during childhood and become more common and increase in frequency during adolescence. The eyeball is a bilateral and spherical organ, which houses the structures responsible for vision. Background/aims Whereas myopic optic disc deformation has been posited as a risk factor for glaucomatous damage, longitudinal studies evaluating their association have been sparse. 11.23B.

Three serial scans are obtained with each test. Optic chiasma lies typically about 10 mm above the pituitary gland, separated by the suprasellar cistern. Ganglion cells originating in the areas of the retina nasal to the disc do not have to arc around the macula. The blind spot indicates the location of the optic nerve head—an area with no photoreceptors—in the temporal part of the visual field. The American Journal of Ophthalmology is a peer-reviewed, scientific publication that welcomes the submission of original, previously unpublished manuscripts directed to ophthalmologists and visual science specialists describing clinical investigations, clinical observations, and clinically relevant laboratory investigations. On the left a patient with an uncommon cause of a mucocele. Arcuate defects ( Fig. Similarly, the temporal fibers transmit images from the nasal field. The scotoma appears smaller in B as the view of the retina in A is limited to approximately 35 degrees, which extends from the nasal edge of the macula to slightly beyond the temporal edge of the optic disc. This will direct you towards the optic disc, the point at which the vessels enter the retina along with the head of the optic nerve. Optic chiasma lies typically about 10 mm above the pituitary gland, separated by the suprasellar cistern.
