Hypermetropia imatchedwa kusayenerera kwa masomphenya, momwe, pakuyang'ana pa zinthu zakutali, fano silili pa retina, koma kumbuyo kwake. Chifukwa chaichi, munthu amawona zinthu zosaoneka bwino, koma, monga lamulo, ali ndi masomphenya abwino nthawi zambiri (kawirikawiri amatha kuona msinkhu kapena mankhwalawa). Panthaŵi yomweyi, ndi mitundu yobadwa ya hyperopia, munthu akhoza kukhala ndi maso osawona bwino, mosasamala kanthu za kutalika kwa phunziro lomwe likufotokozedwa.
Zifukwa za hyperopia
Pafupifupi ana onse obadwa kumene amavutika ndi hypermetropia chifukwa chakuti diso lalitali pazitsulo za anteroposterior ndi laling'ono kwambiri. Pamene mwanayo akukula, masomphenya amavomereza. Koma ngati izi sizikuchitika, lankhulani za congenital anomaly, yomwe imabwera chifukwa cha mphamvu yofooka yopanda mphamvu ya cornea kapena lens.
Anthu achikulire amadziwa kuti kuyang'anitsitsa ndikuphatikizana, osati kupatula kapena kudziwa momwe angasankhire magalasi opanda mankhwala mwa njira zoyesera, kudalira zozizwitsa, zomwe zingayambitse ophthalmologist kuchita mantha. Ndili ndi zaka, mandala amalephera kusintha kusinthasintha, ndipo pambuyo pa zaka 45 ayenera kuwerenga pamene akusunthira bukuli kutali ndi maso.
Magalasi oyang'anitsitsa
Tikamayankhula za kuwonjezera, timatanthawuza ma dioptri ndi maso - ichi ndi chiyero chomwe chimapanga mlingo wa zovuta. Kotero, ndi hyperopia yofatsa, maselo amasankhidwa mpaka +2.0 diopters; digiri yapamwamba imadziwika ndi chizindikiro cha +5.0, ndipo chapamwamba ndi kuposa +5.0.
Ngati munthu sakugwiritsa ntchito mankhwala osokoneza masomphenya, omwe tidzakambirana nawo, tilankhulani ndi lens kuti tiwone bwino kapena magalasi omwe amatha kukuthandizani kuthetsa mavuto pamene mukugwira ntchito ndi zinthu zapafupi - zimangotengedwa ndi dokotala basi.
Kodi mungakonze bwanji vuto la hyperopia?
Kujambula zamakono zamaso masiku ano kuli ndi njira zambiri zobwezera masomphenya. Zaka makumi angapo zapitazo chipambano mderali chinapangidwa ndi njira yopangidwira pa cornea (radialotomy). Pamene zochitika zazikuluzikulu zinachiritsidwa, mawonekedwe a cornea anasintha, omwe amachititsa kuwonjezeka kwa mphamvu yake yowala.
Tsopano mankhwalawa amaonedwa kuti ndi owopsa, osadziwika komanso osokonekera, kuyambira machiritso amatha nthawi yaitali, pambali pake, sangathe kugwiritsira ntchito maso nthawi yomweyo.
Njira yodziwika kwambiri ndi yotsimikizirika ya lero ndi kukonza laser la masomphenya, yomwe ikuchitika tsiku limodzi. Dothi laser lakonza maonekedwe a cornea popanda kuloŵa muzitali zakuya. Ndi kuyang'ana kwakukulu kwapamwamba kunayambitsa kukhazikitsidwa kwa lenti yopangira kapena ma lens enieni.
Madokotala amaona kuti njirazi ndi zotetezeka ndipo zimapereka chiwopsezo chochepa, koma kwa odwala ambiri, ngakhale 1% mwa kuthekera kwa zotsatira zowonongeka kwa masomphenya ndi kutsutsa. Chifukwa ambiri amangovala magalasi kapena magalasi kuti asamayang'ane. Mankhwala osokoneza bongo amakhulupirira kuti izi zimapweteka kwambiri masomphenya.
Kukonzekera kwa hyperopia m'njira yosagwiritsidwe ntchito
Mankhwala amtunduwu amasonyeza kutenga mankhwala otchedwa grasslands kuchokera ku Grasslands mpesa ndi madzi okoma ngati njira yolimbikitsira masomphenya.
M'zaka zaposachedwapa, njira zofala zomwe sizinali zachikhalidwe zotsutsana ndi hyperopia, myopia komanso ngakhale matenda. Njirayi inayambitsidwa ndi dokotala wa mankhwala osakhala a Mambo M. Norbekov. Wodwala amaperekedwa tsiku ndi tsiku kuti azichita masewera olimbitsa thupi , maseŵera osavuta a maso, kutsatira mkhalidwe, kumwetulira ndi kukhulupirira kuti izi zigwira ntchito. Njirayo imatsutsidwa mobwerezabwereza kuchokera kwa madokotala a chikhalidwe, koma intaneti ili ndi ndemanga yambiri pazothandiza za mankhwalawa.
