Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Tsinga yokuona inobuda mumuromo (chiso chetsoka) ichipfuura nomumugwagwa wokuona, ichienda nechokumusoro-pakati ichienda kuchiasm yokuona, uko kunenge kune kusarudzika (kuyambuka) kwemicheka inobva muminda yokuona yenguva pfupi (hemi-retina yemhino) yemaziso ose. Chiyero chetsinga dzinobvisa tsinga chinosiyana-siyana pakati pemarudzi, uye chinoenderana nechiyero chechiono che binocular chinofarirwa nemarudzi. Mazhinji emaaxon etsinga yokuona anoguma mugeniculate nucleus yokumativi uko mashoko anoendeswa ku visual cortex, nepo mamwe maaxon anoguma mu pretectal nucleus uye anobatanidzwa mukufamba kwemaziso. Mamwe ma axon anoguma mu suprachiasmatic nucleus uye anobatanidzwa mukudzora kutenderera kwekurara-kumuka. Dhayamita yaro inowedzera kubva pa1.6 mm mukati meziso kusvika pa3.5 mm mukati mebhora kusvika pa4.5 mm mukati medehenya. Kureba kwezvikamu zvetsinga yokuona kuri 1 mm mupasi rose, 24 mm mumugwagwa, 9 mm mumugwagwa wokuona, uye 16 mm muchikamu chomusoro usati wabatana nechiasm yokuona. Ikoko, kusunungurwa kwechikamu kunovapo, uye inenge 53% yenhengo dzomuviri dzinopindana kuti dziumbe nzira dzomuviri dzomuviri. Mazhinji etsinga idzi anoguma mumuviri we lateral geniculate. Zvichienderana nemagadzirirwo akaitwa muviri, tsinga yokuona inogona kukamurwa kuva zvikamu zvina sezvinoratidzwa pamufananidzo uri pamusoro pechikamu chino (maonero aya ari kubva kumusoro sokunge kuti uri kutarisa muchivanze mushure mokunge musoro weganda romusoro wabviswa): 1. musoro wokuona (uko kunotangira mubhora remaziso (globe) neshinda dzinobva muretina; 2. chikamu chemuviri (chinova chikamu chiri mukati mechivanze). 3. rutivi rwomukati rwemapfupa (rwunova rutivi rwomukati rwemukanza wemapfupa anozivikanwa semukanza weoptic); uye, 4. rutivi rwemusoro (rwunova rutivi rwomukati memukanza wemapfupa, runoguma pachiasm yeoptic). Kubva mumuviri we lateral geniculate, tambo dzeradiation yeoptic dzinopfuura kuenda ku visual cortex mu occipital lobe yeuropi.
