Pawiri myopic astigmatism m'maso onse ana: chithandizo

Kwa anthu ambiri, masomphenya ndi wofunika kwambiri maganizo. Uyamiko kwa Iye, timatenga pafupifupi 90% ya mfundo chilengedwe. Choncho ndikofunika kuteteza maso kuyambira ndili wamng'ono. Mwatsoka, zina matenda zimachitika mwana. Kusunga amatha kuona mmene ndingathere, muyenera nthawi kukaonana ndi maso kukonza masomphenya. Mmodzi wa pathologies anandiuza ali wamng'ono akuti ndi pawiri myopic astigmatism. chikhalidwe ichi si matenda, ndi m'malo mawonekedwe diso chilema. Komabe, pamene linaphwanya magawo kuwala zofunika masomphenya yachibadwa.

astigmatism ndi chiyani?

Monga mukudziwa, luso bwino kuona chithunzichi zimatheka ndi dongosolo ndi kuwala, kudzera mwa maso athu. Chiwalo pamaso ali 5 TV refractive, kenako fano imagwera pa diso. Kuti chithunzi si molakwika, kukula ndi mawonekedwe a diso ayenera kukhala wangwiro. Mwatsoka, ili ndi silinkachitidwa anthu onse. Nthawi zina, agonjera fano lolunjika kumbuyo diso kapena kutsogolo kwa izo. Chifukwa ndi myopia kapena hyperopia. Astigmatism ndi kwaiye pamene diso la munthu sangathe kusonkhanitsa chifanizo cha cholinga limodzi. Ichi ndi chifukwa chakuti mawonekedwe aliyense wa refractive TV dongosolo kuwala ndi sanali abwino dera. Nthawi zambiri ndi mandala kapena diso. Pawiri myopic astigmatism kumachitika pamene fano lolunjika kutsogolo kwa diso. Motero, zinthu kuoneka sawona bwinobwino, sawona bwinobwino.

Zimayambitsa astigmatism

Nthawi zambiri, myopic astigmatism ndi kobadwa nako chilema, monga yaikidwa mu utero. Chifukwa ambiri - ndi cholowa. Nthawi zambiri, ngati astigmatism ndi makolo, ndi imfa ndi mwana. Kawirikawiri osasamba mawonekedwe a diso kapena mandala, pali mwana. Kuwonjezera kwa makolo chilema akhoza Adutsa agogo. Nthawi zina pawiri myopic astigmatism ndi kwaiye chifukwa cha matenda intrauterine kapena kuvulala ndi sadalira mbiri banja. Nthawi zina, chilemacho diso dongosolo kuwala limapezeka akulu. Dziwani zimene zimayambitsa zotsatirazi anapeza astigmatism:

1. Subluxation disolo. Zimachitika pa choipa.
2. Mabala pa diso la. Zikhonza kukhalapo pa zifukwa zosiyanasiyana (zambiri ndi kuvulazidwa ndi matenda aakulu osachiritsika).
3. Kusintha mawonekedwe a nsagwada chapamwamba. Zimacitika pamene pamene sitili mano chapamwamba, malocclusion.
4. Maopaleshoni zimene zimakhudza maso.
5. njira yotupa mu diso pa.

Nthawi zambiri anamuona pa ana pawiri myopic astigmatism m'maso onse. Zooneka acuity Pankhaniyi angakhale osiyana. Ngati chilema ndi kuthi pa moyo, kawirikawiri amakhala diso limodzi.

Mlingo wa astigmatism myopic

Mofanana ndi kuyan'anila onse astigmatism refractive lili madigiri 3 mwamphamvu. Malinga ndi msinkhu ndi nkhawa pa limba la masomphenya, iwo ndi nkhani kusintha moyo. Mwachitsanzo, mu makanda anati astigmatism thupi, umene kusintha kwa zaka 2-3 yekha. Mu zina, ikukula kwambiri ndipo ayenera kuwaona ana aang'ono. Pawiri myopic astigmatism umakondera zikutanthauza kusintha acuity zithunzi mpaka 3 diopters. Mu ana, tiyenera tikonze. Mlingo pafupifupi zikutanthauza kuchepa acuity zithunzi kuchokera diopters 3 mpaka 6. Kuwonjezera malangizo zofunika kuvala magalasi apadera. Aakulu astigmatism kumayamba kuchepetsa 6 diopters kapena zambiri. Zimenezi zingachititse kuti matenda osiyanasiyana. Nthawi zambiri strabismus aakulu akufotokozera, worsens ndi binocular stereoscopic masomphenya.

Chithunzi matenda ndi astigmatism

Zizindikiro za astigmatism zimadalira kusalekerera lapansi. Ndi zizindikiro wofatsa matenda mwina kwina. Kusintha acuity zithunzi pa 1.5-2 diopters amakhala noticeable. Kawirikawiri madandaulo kubwera pa m'badwo woyambirira (3 mpaka 5 zaka). Ana amavutika kuona zinthu kutali, makalata. Kuti akaonetsetse chithunzichi odwala astigmatism zimaphethira maso, anakoka chivindikiro kapena akutembenuza mitu yawo. chizindikiro china ndi mofulumira diso kutopa. Makamaka noticeable Titakhala pa kompyuta, kuwerenga. ana okulirapo komanso akuluakulu amadandaula kusawona bwino. Kusiyanitsa zizindikiro zotsatirazi: zinthu awiri, blurring, kulephera kudziwa pafupifupi mtunda kuchokera fano. Komanso, pambuyo katundu odwala zikhoza kukhala zozunguza mutu kupweteka, kudzikayikira "mchenga m'maso."

Pawiri myopic astigmatism ana: matenda

Matendawa "astigmatism" N'zosatheka wapadera chida anayendera. Ngakhale madandaulo yeniyeni, sikutheka kukatenga mfundo paokha. Matenda pati ndi mtundu wa astigmatism n'kofunika Kupenda ndi maso ndi. Mu malo oyamba amati wa zithunzi acuity (mphamvu kuona makalata kapena zithunzi patali). Kenako anapanga visometry. Njira imeneyi ndi kutsimikizira refraction ndi kusankha magalasi zosiyanasiyana za mphamvu refractive. Diso lililonse lili paokhapaokha (mu nkhani iyi pafupi wachiwiri). M'pofunikanso kuti scotoscopy. Iye akusuntha mithunzi ndi kayendedwe zokhala. Nthawi zina (ana) amathera refractometer. Diso ichi chisanadze anaika kukwaniritsa dilatation a mwana (mydriasis). Pambuyo - kuyeza refraction. M'zipatala apadera kuchita maluso monga kompyuta corneal zimachititsa chilumbachi ndi Oftalmometres. Ndi thandizo lawo kudziwa kukula kwa disolo ndi diso.

Kodi kuchita kusunga masomphenya anu ndi astigmatism?

Pawiri myopic astigmatism amafuna kudzudzulidwa zonse. Choyamba muyenera kudziwa za malamulo zithunzi katundu. Anthu ndi astigmatism sangathe nthawi yambiri kutsogolo kwa TV ndi kompyuta, kuwerenga mu chipinda mdima. M'pofunikanso kusankha ntchito kupsyinjika kochepa pa maso (osavomerezeka kukonza mfundo zazing'ono). Mu astigmatism aakulu simungathe kuyendetsa galimoto, ndi kunkhondo. Pambuyo ntchito zithunzi ndi zofunika kuchita Zochita wapadera kuti maso.

Pawiri myopic astigmatism: mankhwalawa chilemacho

Pali njira zosiyanasiyana kukonza chilema izi. Kwambiri adalipo ndipo ambiri ankaona kuvala magalasi kukhudzana. Iwo kusintha mawonekedwe a diso ndi kuthandiza zolondola pawiri myopic astigmatism m'maso onse. Chithandizo ndi magalasi ndi zovuta zambiri, kuyambira m'pofunika kuphatikiza ndi cylindrical ndi magalasi ozungulira. Ankagwiritsanso laser kuwukonza astigmatism. Ndi kusintha kuya (umapezeka) la diso la.
