Kuwoloka kwa Maso
Kutuluka kwa maso a mwana pakadutsa pafupifupi miyezi 4 mpaka 5 ndi yachibadwa. Komabe, kudutsa maso kwa maso nthawi zonse kungakhale kovuta. Pamene diso limalowa mkati limatchedwa isotropia. Esotropia ndi mtundu wa strabismus. "Eso" amatanthawuza kutembenukira kumphuno. Esotropia ikhoza kuchitika mu diso limodzi kapena kusintha pakati pa maso onse awiri. Sikokwanira kuti maso onse alowemo nthawi yomweyo.
Zimayambitsa
Chifukwa cha esotropia chimadalira pamene choyamba chikuchitika. Kwa akuluakulu, chiwonetsero chodzidzimutsa chasotropia chingakhale chizindikiro cha vuto lalikulu. Kwa ana ndi makanda, isotropia kawirikawiri ndi chizindikiro cha chitukuko chosadziwika cha dongosolo la binocular limene limayamba mu ubongo. Komabe, pali zifukwa zina. Pansi pa miyezi 4 mpaka 5 miyezi, kulowera pakati ndi kawirikawiri ndipo ndi chizindikiro chophunzira momwe mungagwiritsire ntchito maso pamodzi monga dongosolo. Ana ena ndi mafuko angakhale ndi misampha. Izi ndizimene mlatho wa mphuno sunakhazikitsidwe kapena wokhazikika kusiyana ndi wokhazikika. Ana awa ali ndi "epicentral folds" omwe amachititsa kuti ziwonekere kuti diso limatembenuka pang'ono. Pamene khanda likukula, maonekedwe amenewa amatha kuchoka ndipo maso awo amawonekera.
Mitundu
Chiwonongeko chaching'ono: Congenital esotropia ndi mtundu wa esotropia umene ana amabadwa nawo. Kaŵirikaŵiri zimayambitsa kupangika kosazolowereka kwa mitsempha kapena chitukuko chosadziwika bwino m'magalimoto a ubongo.
Chiwonongeko cha congenital nthawi zambiri chimayambira kwambiri pakati pa miyezi 2 mpaka 4 ndipo kukula kwa kupotoka kapena diso kumatembenuka kukhala kwakukulu kwambiri.
Kawirikawiri, makanda omwe ali ndi chiberekero chokhala ndi chiberekero alibe ubwino wochulukirapo kapena osayang'anitsitsa . M'malo mwake zimayambitsidwa ndi chitukuko chosadziwika cha dongosolo la binocular.
Njira yabwino yothetsera uchembere wodwalayo ndi opaleshoni. Kuchita opaleshoni sikumapereka mwayi woti maso azigwirira ntchito limodzi mwachizoloŵezi koma kuti athetse kusokonekera kuti akhale ndi maonekedwe abwino. Maso sangagwirebe ntchito pamodzi, koma mwanayo adzakhala ndi mawonekedwe okongoletsa kwambiri.
Esotropia yokhala ndi malo ogona : Zovuta zowonongeka zimapezeka pamsinkhu wa zaka 2. Zimayambitsidwa ndi vuto ndi machitidwe awiri omwe amayendetsa minofu yathu ya maso ndi kuchuluka kwa maso athu. Njira yowonetsera (kulumikiza) imalola maso athu kusintha mphamvu ndi kuganizira kuti zinthu zisakhale bwino ngakhale patali. Binocular / alignment system ikulamulira mmene maso athu amagwirira ntchito pamodzi. Pamene tiyang'ana kutali, maso athu ali olunjika. Tikayang'ana chinthu choyandikana kwambiri, maso athu amatembenuka kapena kutembenuka ndipo maso athu akuwonjezera mphamvu zawo. Tikamayang'ana kumbuyo, timakhala osamala komanso maso athu amakhalanso olondola.
Ana achichepere ali ndi mphamvu zochuluka kwambiri. Chotsatira chake, ngati mwana ali ndi kutalika kwakukulu kwapadera, mwanayo amayesa kufotokoza momveka bwino. Kuti akwaniritse izi, amayenera kuganizira zambiri kuti athetse vuto la masomphenya osadziwika.
Akamaganizira kwambiri izi, mawonekedwe a binocular ndi ofunika ayamba kupeza zizindikiro zosakaniza. Kawirikawiri, diso limodzi lidzalowa. Chimene chikuyendetsa polojekitiyi chimatumizanso chizindikiro kwa minofu ya maso kuti isinthe mkati. Komabe, pamene akuyenera kuganizira kwambiri, zizindikiro zosadziwika zimapita ku minofu ya maso ndipo kenako diso limodzi limatembenuka ndikudutsa. Ana ena sangapereke malipiro ndipo maso awo sangawoneke, koma adzakhala ndi masomphenya osauka kwambiri chifukwa sakhala opitirira. Ubongo wawo umasankha kuti minofu ikhale yolunjika, koma amawona chithunzi chosowa kwambiri.
Mavuto
Amblyopia : Amblyopia ndi vuto loyamba lachitukuko lomwe limagwirizanitsidwa ndi esotropia.
Amblyopia ndi chikhalidwe chimene chimapezeka pamene wina kapena onse awiri sakuwona chithunzi chowonekera. Ngati chithunzichi sichikuwonekeratu kwa nthawi yaitali, nthawi yowona masomphenya ingayambe. Mu esotropia, diso limodzi likhoza kutembenuzidwa. Pamene diso likutembenuzidwa, ubongo umalepheretsa kapena kusanyalanyaza chithunzi chomwe maso amachiwona. Apo ayi, munthu yemwe ali ndi esotropia amakhoza kuona kawiri nthawi zonse. Ngati ubongo umalepheretsa diso limenelo kawirikawiri, njira yowonjezera ya ubongo wa munthu imasokonezeka ndipo imayambitsidwa molakwika. Mmene thupi la munthu limagwirira ntchito ndi "pulasitiki" mpaka zaka zisanu ndi ziwiri (7) ndipo akatswiri ena amanena kuti atakwanitsa zaka 14. Pambuyo pokhala ndi zaka 14, ubongo ndi dongosolo lamanjenje zimakhala zovuta kwambiri ndipo zimakhala zovuta kusintha masomphenya kumbuyo. Choncho, mankhwala oyambirira ndi ofunikira. Ngati nkhanza zikuyambira ali wamng'ono, kusintha kwa masomphenya kumatheka.
Kupanda kuzindikira kozama : Anthu ndi zinyama ali ndi lingaliro lozama chifukwa ali ndi maso awiri. Kupitiriza kupatula maso a zinyama ndiko, lingaliro lozama bwino ndilo. Pamene diso limodzi likutembenuzidwira kapena kuponderezedwa, munthu yemwe ali ndi esotropia amangowona ndi diso limodzi. Ngakhale pali zochitika zachilengedwe kuti ziweruzire zakuya, kuzindikira kozama kozama kumachepetsedwa. Anthu omwe ali ndi esotropia amakhala ndi nthawi yovuta kuona zithunzi ndi mapuzzles atatu. Izi zingakhudze machitidwe a masewera kapena ntchito zamtsogolo.
