Compound astigmatism myopic kuzo zombili amehlo ezinganeni: ukwelashwa

Kubantu abaningi, umbono obaluleke kakhulu izinzwa. Siyabonga kuye, sithatha cishe u-90% ulwazi kusuka imvelo. Ngakho-ke kubaluleke kakhulu ukuvikela amehlo kusukela zisencane. Ngeshwa, ezinye izifo zenzeka eminyakeni yobungane. Ukuze silondoloze ikhono ukubona ngangokunokwenzeka, nani nidinga isikhathi ukuze abonisane kudokotela wezifo zamehlo ukulungisa umbono. Omunye pathologies kutholakala ukuthi uphethwe yini zisencane ubhekwa kwakwakhe astigmatism myopic. Lesi simo akusona isifo, kuba kunalokho ifomu lwesici iso. Nokho, uma esephula nemingcele optical ezidingekile umbono ovamile.

Kuyini astigmatism?

Njengoba wazi, ikhono lokubona ngokucacile isithombe ibangelwa uhlelo optical, emelelwa amehlo ethu. Isitho obonayo has 5 abezindaba yezokubona, ngemva kwalokho isithombe ewela i-retina. Ukuze isithombe hhayi ehlanekezelwe isayizi shape esweni kumelwe kube umuntu ophelele. Ngeshwa, lokhu akulona ebonwe bonke abantu. Kwezinye izimo, izihloko isithombe igxile ngemuva retina noma phambi kwalo. Umphumela myopia noma hyperopia. Astigmatism ekhiqizwa lapho Iso lomuntu liwumsebenzi abakwazi ukuqoqa umfanekiso ngokugxila olulodwa. Lokhu kungenxa yokuthi ifomu yimiphi abezindaba yezokubona uhlelo optical kuyinto sphere non-ekahle. Ngokuvamile kuba lens noma i-cornea. Compound astigmatism myopic kwenzeka uma isithombe ugxile ngaphambi kwe-retina. Ngenxa yalokho, izinto avele ukufiphala, ukufiphala.

Izimbangela astigmatism

Ezimweni eziningi, astigmatism myopic Inesici azalwa naso, njengoba sibekwa utero. Isizathu ezijwayeleke kakhulu - kungcono sitholwa njengefa. Ezimweni eziningi, uma astigmatism abe umzali, uphasiswe kanye nengane. Akuvamile ukuma obuhlukahlukene cornea noma lens, kukhona kuphela ingane. Ngaphezu abazali, isici ingadlulela kumkhulu nogogo nakubazali. Ngezinye izikhathi kwakwakhe astigmatism myopic ekhiqizwa ngenxa ukutheleleka intrauterine namkha ukulimala begodu akuxhomekile umlando womndeni. Kwezinye izimo, isici iso uhlelo optical livela abadala. Yazi izimbangela ezilandelayo astigmatism atholwe:

1. Subluxation lens. Kwenzeka ngesikhathi yokulimala.
2. Izibazi ku-cornea. Kungenzeka ngenxa yezizathu ezihlukahlukene (ngokuvamile kuba ukulimala, kanye nezifo ezingamahlala khona esiwohlozayo).
3. Ukushintsha ukuma ongenhla. Kuzokwenzeka uma engekho namazinyo engenhla, malocclusion.
4. Ukuhlinza ezithinta zamehlo.
5. izinqubo ukuvuvukala kule cornea.

Ngokuvamile ebonwe izingane kwakwakhe astigmatism myopic kuzo zombili amehlo. Visual acuity kulesi simo zingase zihluke. Uma isici lutholwa besekhona, kuvamise iso elilodwa.

I degree of astigmatism myopic

Njengazo zonke ukwephula astigmatism yezokubona it has 3 lamadigri zaba namandla kakhulu. Kuye ngobudala ukucindezeleka phezu uhlaka umbono, angaphansi ukushintsha kukho konke ukuphila. Ngokwesibonelo, ezinsaneni waphawula astigmatism bokuphila, okuyinto kushintshwe iminyaka 2-3 kuphela. Kwezinye izimo, kuba likhula ngokushesha futhi sidinga ukulashelwa ekuqaleni kuka ebuntwaneni. Compound myopic astigmatism kancane kusho ushintsho acuity ezibukwayo kuze 3 diopters. Ezinganeni, kungaba ukulungiswa. Izinga isilinganiso kusho ukwehla acuity ezibukwayo kusuka 3 kuya ku-6 diopters. Ngaphezu ukulungiswa ezidingekayo ukugqoka izibuko ezikhethekile. astigmatism Sinzima iqala lwehlise 6 diopters noma ngaphezulu. Lokhu kungaholela kwempilo. Ngokuvamile ne-strabismus ezinzima eba, siba sibi futhi Binocular Umbono stereoscopic.

Lwasemtholampilo isithombe nge astigmatism

Izimpawu astigmatism zincike kobukhulu. Nge izimpawu zokwelashwa omnene kungenzeka ukuthi ingabi khona. Ushintsho acuity yokubonakala 1.5-2 diopters iba lubonakale. Ngokuvamile izikhalazo ukuza esemncane (3 kuya 5 iminyaka). Izingane ube nobunzima bebona ezikude izinto, izincwadi. Ukuze asibuke kahle lesitfombe, iziguli ezinemishini astigmatism blink amehlo, ngadonsa lid noma jika bo phathi. Olunye uphawu iyona rapid eye ukukhathala. Kungokuphawulekayo ukuthi ikakhulukazi ngemuva kokuhlala e-computer, ukufunda. Izingane ezindadlana nabantu abadala esekhala angaboni kahle. Hlukanisa zimpawu ezilandelayo: izinto double, ukufiphala, ukungakwazi ukucacisa cishe ibanga kusuka isithombe. Futhi, ngemva umthwalo iziguli kungaba buhlungu yibe yinto exakayo, umuzwa "isihlabathi emehlweni."

Compound astigmatism myopic ezinganeni: Ihlahlubo

Sifo "astigmatism" akunakwenzeka ngaphandle ithuluzi ukuhlolwa okukhethekile. Naphezu izikhalazo ezithile, akunakwenzeka ukuba sithathe amaphuzu bebodwa. Ukuxilonga ubukhulu nohlobo astigmatism kuyinto luhlolo ezidingekayo kudokotela wezifo zamehlo. Endaweni kuqala ukulinganisa acuity ezibukwayo (lokubona izinhlamvu noma izithombe bekude). Khona-ke wenza visometry. Le ndlela ukuqinisekisa kwalungiswa izinkunga zokubona ngumuntu ukukhethwa lens ezahlukene amandla yezokubona. iso ngamunye ngemibuzo bengabodwa (kulokhu eduze yesibili). Kuyadingeka ukuba scotoscopy. Yena ezihambayo izithunzi ne ukunyakaza oscillating. Kwezinye izimo (izingane ezingaphezu) ukuchitha refractometer. Ngenxa yalesi iso zangaphambi safaka ukufeza dilatation we umfundi (mydriasis). Ngemva - ukukala kwalungiswa izinkunga zokubona. Emitholampilo ezikhethekile enze emasu lafana esebenza nge-computer sendawo corneal Oftalmometres. Ngosizo lwabo ukucacisa ubukhulu lens futhi cornea.

Okufanele ukwenze ukugcina umbono wakho nge astigmatism?

Compound astigmatism myopic kudinga ukulungiswa njalo. Okokuqala odinga ukukwazi mayelana ezibukwayo umthwalo imikhawulo. Abantu ne astigmatism abakwazi ukuchitha isikhathi esiningi phambi TV nekhompyutha, ukufunda egumbini elimnyama. Kuyadingeka ukuba ukhethe umsebenzi nokucindezeleka sakugcina amehlo (akunconywa ukulungisa imininingwane ezincane). Ngo astigmatism ezinzima abakwazi ukushayela imoto, futhi ibe sebuthweni lezempi. Ngemva umsebenzi ezibukwayo kuyadingeka ukwenza umzimba esikhethekile emehlweni.

Compound astigmatism myopic: ekwelapheni isici

Zikhona izindlela ezehlukene sokulungisa le nkinga. I kunazo ayethanda futhi kubhekwa kabanzi okokugqoka contact lens. Bona ulungise ukuma cornea nokusiza kwakwakhe lesifanele astigmatism myopic kuzo zombili amehlo. Ukwelashwa nge izibuko kuba yinkimbinkimbi, ngoba kuyadingeka ukuze uhlanganise cylindrical futhi lens eyindilinga. Futhi wenza laser yokulungiswa astigmatism. Kuyinto ukushintsha ukujula (ukugaya) ka-cornea.
