Kupfuura: Iyo optic nerve inosiya orbit (eye socket) kuburikidza neiyo optic canal, ichimhanya postero-medially yakananga kune optic chiasm, uko kune chikamu chakatemwa (kuyambuka) kwemafiber kubva kune temporal visual fields (the nasal hemi-retina) yemaziso ese ari maviri. Huwandu hwe decussating fibers hunosiyana pakati pemarudzi, uye hunoenderana nedhigirii rekuona binocular inofadzwa nemhando. Mazhinji ema axon eiyo optic nerve anoguma mune lateral genic nucleus kubva pano ruzivo rwunotumirwa kune yekuona cortex, nepo mamwe ma axon achipera mune rectal nucleus uye achibatanidzwa mukufamba kwekufungidzira kweziso. Mamwe ma axon anoguma mu suprachiasmatic nucleus uye anobatanidzwa mukugadzirisa kweiyo optic retic cycle. Its reticular diameter inenge 1.6 mm mukati meiyo orbital nzvimbo yekuona (the nasal hemi-retina) yemaziso ese ari maviri.
