Astigmatism myopic ambaxa emehlweni omabini ebantwaneni: unyango

Kuba abantu abaninzi, umbono yeyona nto ibalulekileyo izivamvo. Enkosi kuye, sithatha phantse 90% kwengcaciso evela kokusingqongileyo. Ngoko ke kubaluleke kakhulu ukuba ukukhusela amehlo esemncinane. Ngelishwa, ezinye izifo kwenzeka ebuntwaneni. Ukugcina ukukwazi ukubona kangangoko kunokwenzeka, udinga ixesha ukudibana zamehlo ukulungisa umbono. Enye ezimbi bene esemncinane ithathwa astigmatism compound myopic. Le meko ayikho isifo, oko kunokuba luhlobo lweliso siphene. Noko ke, xa kuphula woqondo iparameters eziyimfuneko umbono eqhelekileyo.

Yintoni astigmatism?

Njengoko usazi, ukukwazi ukubona ngokucacileyo umfanekiso kuphunyezwa kwinkqubo enombala, emelwe amehlo ethu. Umbutho emehlweni 5 eendaba zokunganyangeki, emva oluba bomfanekiso retina. Ukuze ukuba umfanekiso ayenziwanga egqwethekileyo, ubukhulu kunye nokumila iliso kufuneka ube ngogqibeleleyo. Ngelishwa, le nto aba bantu bonke. Kwezinye iimeko, obeka umfanekiso swi emva retina okanye phambi kwayo. Isiphumo yi ukubona okanye hyperopia. Astigmatism is generated xa Iliso lomntu akakwazi ukuqokelela umfanekiso kujoliswe elinye. Oku kubangelwa yinto yokuba fom naziphi na eendaba zokunganyangeki inkqubo enombala yi sphere non-efanelekileyo. Amaninzi oko ilens okanye inwebu. astigmatism Compound myopic kwenzeka xa umfanekiso swi phambi kwiretina. Ngenxa yoko, izinto kubonakala kufiphale, kufiphale kancinane.

Izinto ezibangela astigmatism

Kwiimeko ezininzi, astigmatism myopic onesiphene awazalwa enaso, njengokuba sibekwa Esibelekweni. Isizathu iqhelekileyo - its njengelifa. Kwiimeko ezininzi, ukuba astigmatism ube ngumzali, udlulela kunye nomntwana. Ayifane imilo mgaqweni le inwebu okanye lens, kukho kuphela usana. Ukongeza kubazali, isiphako ukuhambisela phambili nomkhulu. Ngamanye amaxesha astigmatism compound myopic wenziwa ngenxa yokuba usuleleko intrauterine okanye ukwenzakala kwaye kuxhomekeke kwimbali yosapho. Kwezinye iimeko, isiphako inkqubo optical iliso kuvela abadala. Zazi izinto ezibangela zilandelayo astigmatism ozifumeneyo:

1. Subluxation lens. Oku kwenzeka ngexesha lokwenzakala.
2. Yayenze phezu inwebu. Ngamana kwenzeka ngenxa yezizathu ezahlukeneyo (ngokufuthi ukwenzakala, kunye nezifo ezinganyangekiyo sisiba mandundu).
3. Ukutshintsha imilo kwemihlathi eliphezulu. Kwenzeka xa engekho amazinyo aphezulu, malocclusion.
4. Utyando ezichaphazela ukungaboni.
5. iinkqubo ukudumba kule inwebu.

Eyona sivame ukuba abantwana ezimbaxa astigmatism myopic emehlweni omabini. acuity Visual kule imeko inokuba nomahluko. Ukuba isiphako ezifunyenwe ngexesha ebomini, kuvamise iliso elinye.

The degree of astigmatism myopic

Njengazo zonke Kukwaphula astigmatism zokunganyangeki ngayo elithile 3 ubungnqongqo. Kuxhomekeka kubudala noxinezeleko phezu isebe embonweni, kuxhomekeke ukutshintsha ubomi. Ngokomzekelo, xa iintsana baphawula astigmatism komzimba, nto leyo hlengiswe ukuya kwiminyaka 2-3 kuphela. Kwezinye iimeko, ubukhula ngokukhawuleza kwaye kufuneka ziphathwe ebuntwaneni ekuqaleni. Ambaxa myopic astigmatism elincane ithetha utshintsho acuity olubonakalayo ukuya diopters-3. Ebantwaneni, oko alungiswe. Le wononophelo kuthetha ukuncipha acuity olubonakalayo ukusuka diopters-3 ukuya ku-6. Ukongeza nokulungiswa kuyimfuneko ukuba izibuko ezizodwa. astigmatism ezimandundu iqala ekunciphiseni diopters-6 okanye ngaphezulu. Oku kunokukhokelela zezigulo ezahlukeneyo. Amaxesha amaninzi ne strabismus kakhulu uvela, mandundu kwaye binocular umbono eyodwa.

Lo mfanekiso clinical ne astigmatism

Iimpawu astigmatism zixhomekeke ebukhulwini. Iimpawu zonyango ngobulali babe khona. Ukutshintsha acuity olubonakalayo kwi 1.5-2 diopters iba buqapheleke. Ngokuqhelekileyo izikhalazo kuza esemncinane (iminyaka emi-3 ukuya ku-5). Abantwana kunzima ukubona izinto ezikude, iileta. Ukufumana ujongo ngcono lo mfanekiso, izigulane astigmatism blink amehlo, banduluka isiciko okanye ajike iintloko zabo. Olunye uphawu lo iliso kudinwa ngokukhawuleza. Kuyinto lubonakale ngokukhethekileyo emva kokuhlala kwi computer, ukufunda. abantwana abadala kunye nabantu abadala ezikhala ukungaboni. Ukwahlula ezi mpawu zilandelayo: izinto kabini, ungabe, ukungakwazi ukufumanisa umgama ukusuka umfanekiso. Kwakhona, emva kokuba umthwalo izigulane zinokuba intlungu lisenokubhidekisa, yimvakalelo 'intlabathi emehlweni. "

astigmatism myopic ambaxa ebantwaneni: isifo

Uxilongo "astigmatism" akunakwenzeka ngaphandle ukuhlolwa isixhobo okhethekileyo. Nangona izikhalazo ezithile, akunakwenzeka ukuba pick up amanqaku ngokwabo. Ukufumanisa ubungakanani kunye nohlobo astigmatism kuyimfuneko iimviwo yi zamehlo. Kwindawo yokuqala uqikelelo acuity olubonakalayo (ukukwazi ukubona iileta okanye imifanekiso evela kude). Emva koko wenza visometry. Le ndlela ukungqinisisa refraction ngokuthi kukhethwe lens ezahlukeneyo ngamandla zokunganyangeki. Iliso ngalinye okuhlolisiswa ngokwahlukileyo (kulo mzekelo n'wina yesibini). Kwakhona kuyimfuneko ukuba scotoscopy. Yena ihamba izithunzi kunye iintshukumo jinga. Kwezinye iimeko (abantwana) tirhisa refractometer. Ngokuba lo iliso pre-wabethelela ukufezekisa dilatation lo umfundi (mydriasis). Emva - ukulinganisa refraction. Kwiiklinikhi ezizodwa enze ubuchule ezifana mphandle yekhompyutha kwenwebu kunye Oftalmometres. Ngoncedo lwabo ukubala ubungakanani lens kanye inwebu.

Kufuneka wenze ntoni ukuze ugcine umbono wakho astigmatism?

astigmatism Compound myopic ifuna ukulungiswa rhoqo. Okokuqala kufuneka wazi malunga izithintelo umthwalo olubonakalayo.

Treatment kunye izibuko sinzima ngakumbi, ekubeni kuyimfuneko ukudibanisa zezindlu kunye lens ukulenza. Kwakhona wenza laser ukulungiswa astigmatism. Kuyinto ukutshintsha ubunzulu (nokutshixiza) of the inwebu.
