Kurwadza kunogona kukonzera kushanduka kukuru mune zvakaratidzwa. Kazhinji yenguva, munhu anopona chirwere anongorarama chete, kana zvimwe zvishoma zvezviono izvi zvinoshanduka, asi kwete dzose. Ichi ndechokuti nzvimbo dzakasiyana dzehuropi dzinoshanda pamwe chete kuti dzidzora maonero. Saka, zvichienderana nehukuru uye nzvimbo yekurohwa, zvinogona kana kuti hazvigoni kuchinja zvinhu zvakasiyana-siyana zvekuona.
Homonymous Hemianopsia: Visual Field Cut kana Kurasikirwa kwePeriipheral Vision
Munda unoonekwa unopera kurasikirwa kwechikamu chemaonero. Nzvimbo yekuona yakaoma inogona kukonzera kurasikirwa kworuboshwe kuruboshwe kana kuruboshwe, mumumunda wepamusoro wekuona, munzvimbo yakaderera yekuratidzwa, kana kuti pamwe chete.
Kukwanisa kwedu kuona nyika kunobva pauropi pakuona nyika inotitenderedza sekuti yakaita peta ina-yepamusoro yakaiswa pamwe chete pamwe chete kuti iite pie yakazara. Apo sitiroko inokonzera homonymous hemianopsia , maziso ose anotadza kukwanisa kuona "zvimwe zvimedu zvekudya." Nokudaro kurasikirwa kwemaziso kunogona kuita kuti maziso ose asagona kuona rutivi rworuboshwe kana maziso ose asingakwanisi kuona rutivi rworudyi kana maziso ose asingakwanisi kuona kumusoro kwepamusoro kana kumusoro kwekumativi kumativi.
Izvi zvakasiyana-siyana zvekurasikirwa kwezviratidzo zvinowanzoitika nekuda kwekurohwa zvinorondedzerwa sekuti hazvizivikanwi nehemianopsia uye zvinogona kunyatsotsanangurwa sekusara kusingazivikanwi hemianopsia, kodzero yakarurama yehemianopsia, kodzero yepamusoro quadrant hemianopsia, nezvimwe zvakadaro.
Homonymous hemianopsia inogona kuitika kana kurohwa kunokanganisa nzvimbo yenguva yemaore, parietal lobe kana occipital lobe. Nzvimbo chaiyo yekurohwa kunogadzirisa zvakananga nzvimbo yekurasikirwa kworatidzwa. Kukuvadza kune rumwe rutivi rworudyi rweuropi kunokonzera kurasikirwa kwekuratidzwa kwemaodzanyemba, asi kukanganisa kuruboshwe rweuropi kunokonzera kukanganiswa kwemaonero.
Kunyanya Kusarura Kana Kuonekwa Kunopera
Kuona kusakanganiswa kwakave kwakasiyana nedzimwe homonomous hemianopsia. Kuona kusaregererwa ndechiitiko umo vapukunyuka vashoma havagone kuona zvinhu zvinowanzosvika mundima yakasara yekuonekwa.
Kuregererwa kweimwe rutivi kunogona kunge kwakakwana (kusatarisira kuremekedzwa) kana kunogona kungoitika apo chimwe chinhu chiri mu "chikamu" chakakwikwidza (kutarisa kwekuona).
Kuona kusaregererwa uye kuonekwa kwekuona zvinowanzoitika apo chirwere chinokanganisa parietal lobe yakarurama.
Diplopia: Dhiyabhorosi Dhiyabhorosi kana Maonero Akasvibiswa
Kuonekwa kaviri kune chikonzero chekurohwa kunokanganisa maziso emeso nenzira iyo ziso rimwe haringagoni kuenderana zvakakwana nedzimwe ziso, kupa pfungwa kwezvinhu zviviri kana pane imwe chete.
Diplopia inogona kuvapo nguva yose, kana inogona kuvapo apo iwe uri kutarisa pane imwe nzira, somuenzaniso kana iwe wakatamisa meso ako kuruboshwe, kurudyi kana kumusoro kana pasi. Kakawanda, diplopia inogona kuita kuti chiratidzo chako chionekwe sechinhu chisina kujeka kana chisingafungiri, pane kunyatsoparadzaniswa kaviri, sezvo mifananidzo miviri inogona kuwirirana, ichioneka ichikanganisa.
Kazhinji yenguva, diplopia inokonzerwa nekurohwa kwe brain brain kana kuti cerebellum , kunyange dzimwe nguva kurohwa uye kurwisana kunogona kubudisa diplopia.
Kurasikirwa kweChiratidzo
Kurohwa kunogona kukonzera kukanganiswa kwepfungwa zvakakwana mune rimwe ziso, uye kazhinji, mumaziso ose. Kurasikirwa kwakakwana kwechiono cheziso rimwe kazhinji kunowanzoitwa semugumisiro wekuvharwa kweimwe yemishonga inopa ropa kuerera muziso, mazamu ophthalmic kana bazi rayo rinonzi retinal arteri.
Vamwe vanopukunyuka chirwere vanogona kurasikirwa nemuono mumaziso maviri mushure mekurohwa kwechiremera chinokanganisa zvose masikati machena, chiitiko chinonzi cortical blindness , izvo zvinoreva kuti muponesi wemupurisa anotarira kuchiedza (vadzidzi vanoita zvishoma pamusana pechiedza) sokunge kuti iye anogona achiri kuona. Muchifukidzo chekoriki, zvakadaro, munhu anenge apona chirwere haagoni 'kuona' nokuti uropi hahwoni kuona mifananidzo.
Dzimwe nguva, vanhu vane kurasikirwa kwemaonero havazivi kuti havagone kuona uye vanoita sevanokwanisa. Izvi zvinonzi Anton's syndrome uye kazhinji zvinokonzerwa nekurohwa kunosanganisira nzvimbo huru dzekuonekwa mune occipital lobes.
Kutarisa Zviratidzo
Kuongorora maziso kunogona kuitika mushure mekurohwa. Hluccinations zviitiko kana pfungwa dzezvinhu zvisingaitiki.
Mamiriro ezvinhu anonzi Charles Bonnet Syndrome anoonekwa nekuitika kwemaonero ekuona vanhu vanoparara avo vane maziso asingaoneki nemhaka yeziso kana chinetso chepfungwa chinosanganisira nzira dzinoonekwa, dzakadai sedanga, glaucoma, kurohwa, uturu hwepfungwa uye kushungurudzika musoro. Vakapukunyuka nesitiroko vane Charles Bonnet Syndrome vanowanzoziva kuti zvinhu zvavanoona 'hazvisi zvechokwadi.
Kuvhiringidzwa munzira inooneka muuropi kunoguma kune nhema dzakaoma maziso ekuonekwa ari kuendeswa kune zvakaratidzwa nzvimbo muuropi. Chirwere mune chero chipi zvacho chezviratidzo zvehuropi zvinogona kukonzera Charles Bonnet chirwere, asi kazhinji kacho, chinokonzerwa nekurohwa kweimwe kana wechipiri lopital.
Achromatopsia kana kurasikirwa kwemavara maonero
Chinhu chisingawanzozivikanwa chinonzi achromatopsia ndiko kurasikirwa kwemavara maziso, zvichiita kuti zvinhu zvive zvakasviba, zvichena, kana gorofu. Zvinokonzerwa nekubatana kwekukuvadza kune zvikamu zvakasiyana-siyana zvehuropi kana nehutachiona hunokonzera, iyi ndeimwe yemarudzo inooneka yepuroke.
Amaurosis Fugax
Amaurosis fugax inoshanduka kuonekwa inobatanidza nehutachiona hwekushamisika kwechirwere (TIA) , iyo iri nguva shoma, yakashandurwa. Izvozvo zvekare zviratidzo zveamaurosis fugax dzinosanganisira mupfungwa kuti mumvuri wemafu kana mapofu zvishoma nezvishoma unofukidza imwe kana maziso ose. Dzimwe nguva amarousis fugax inorondedzerwa sekunonoka kwechiratidzo kana kurasikirwa kworuzhinji.
Chinhu chinokosha chemamaurosis fugax ndechokuti inokurumidza nekukurumidza. Izvi zvinokonzerwa nekupererwa kwenguva pfupi kwekuyerera kweropa kusvika kune ziso, iyo inonzi TIA, inofungidzirwa kusarudzwa kwekutanga. Vanhu vazhinji vanonyunyuta nezvezviratidzo zvinonzwika seamaurosis fugax zvinozoonekwa kuti vane mukati carotid arteri chirwere. Kana chikonzero cheTIA ichizivikanwa uye chichirapwa, chirwere chinogona kudziviswa.
Chiratidzo Chinoshandiswa Kwete Kushamwaridzana neStroke
Pane dzakawanda zvinowanzoonekwa nezvinetso zvinokonzerwa nezvinetso zveziso, hutano kana zvimwe zvirwere, asi kwete chirwere.
- Floaters
Kana iwe ukaona dzimwe nguva "kutenderera" nzvimbo, ichi kazhinji chiratidzo chechirwere cheshuga cheziso, izvo zvingaita kuti zviratidzo zvakanyanya kuchinja kana zvisiyiwa zvisina kutenderwa. Kana iwe ukaona mafashoni, iwe unofanirwa kurapwa mune zvekurapa kuti udzivise humwe hunoona kurasikirwa. - Kuona Halos Around Lights
Chirwere chechirwere, icho chinowanzova chigumisiro chekukwegura kwakakwana, chirwere cheshuga kana kusvuta, chinokonzera pfungwa kuti uri kutarisa kuburikidza negirazi rine marara kana yechando. Kusuruvara kunogona kubudirira uye kwakachengetedzwa. - Pedyo Kuonekwa kana Kure Kurerekedzwa
Zvinetso zvinowanzoitika zvekuswedera pedyo nekuonekwa zvakanyanya ndezvikonzero zvekusatadza kwemaziso. Vanhu avo vari pedyo nekuona vanoomerwa nekufungisisa zvinhu zvisiri kure, asi vanhu vanoona zviri nyore kuisa pfungwa pazvinhu zvakaderera. Izvi zvinetso zvekuzvarwa kana chikonzero chekukwegura kwakanaka, asi kwete stroke. - Triple vision
Hapana chikonzero chaicho chekuti chiitiko chekuona katatu. Vanhu vanoti vanoona zvinhu zvakasiyana-siyana vangave vari pasi pesimba remishonga kana madhiragi kana kuti vane chirwere chepfungwa. - Red Green Color Blindness
Ruvara rwebhuruu ruvara rwehupusi hwakasiyana nechakuchamromatopsia (kana munhu asingakwanisi kuona ruvara.) Ruvara rwebhuruu ruvara rwehupusi hunokonzerwa nehutachiona hwemafu.
Shoko Rinobva
Imwe yematambudziko edu anokosha ndiyo pfungwa yekuonekwa. Chiratidzo chinoda kuwirirana kwakaoma pakati pemeso neuropi. Kurwadza kunogona kukonzera kuchinja kwakasiyana-siyana mukuratidzwa, zvichienderana nekukura kwechirwere, uye nzvimbo ipi yehuropi inoshandiswa. Kugadziriswa kwekurasikirwa kwemaono inzira yakareba inoda kushivirira kukuru uye kushivirira.
