Nystagmus - ntoni na? nystagmus naso. Nystagmus - unyango

Ngamanye amaxesha uthetha umntu, mhlawumbi uqaphele ukuba waba 'run' amehlo. Kulo mzekelo, usenokuvakalelwa kukuba omnye umntu akanamdla incoko okanye akabathembi kuwe. Ujonga kude, akugxininisi ubuso bakho kwaye akaxhasi umjonge emehlweni. Ngelishwa, abantu abakwazi baziphathe ngale ndlela ngenxa ukuthingaza ziqhubeka incoko, kodwa ngenxa yesi sifo, ebizwa nystagmus. Yintoni na, yintoni na oonobangela esi sifo, ene kwaye liphathwe njani? Konke oku, siya ukuchaza ngokweenkcukacha kweli nqaku.

definition of nystagmus

obubonakala kwezonyango esi sifo kakhulu rhoqo, rhythmical, iintshukumo oscillatory ngokuzenzekelayo le amehlo. Umntu nystagmus, akuthethi ingqalelo nasiphi na isifundo. Alinako yi umgudu ukuqala okanye ayeke ngokuzimeleyo intshukumo eye ngokuzenzekelayo. Ngokufuthi sifo kunye ukuhla acuity olubonakalayo. Nge ubudala, iimpawu nystagmus inokuba kuncitshiswa kancinane. Kunjalo, nawuphi na simo okanye ukudinwa kakhulu ndinokuphinda bawaphikise ukonakala kweendlela flow yayo. Nystagmus - ayilo siphene izithambiso, njengoko abaninzi uye ucinge, yaye ingxaki enkulu ngokwenene. Esi sifo Idla yi ukuphazamiseka kwemisebenzi inkqubo olubonakalayo, njengokuba amehlo kwezigulane intshukumo okutyekisayo, kwaye akukho lula ukubona into kakuhle. Abanye abantu ngenxa nystagmus, ingxaki nezinye izifo iliso, babe phantse eyimfama. Phezu kwalo lonke, unako kakhulu akuphazamisi umgangatho wobomi, ezempilo kunye nokulungelelana engqondweni nystagmus yabantu. Yintoni na, Sijonge ngoku kuxoxwe ngembangi, iimpawu kunye neentlobo kwangumqondiso esi sifo.

Izinto ezibangela nystagmus

Le ngezifo oculomotor inokubonakalisa kwasekuzalweni, ebuntwaneni ekuqaleni okanye kuvela ebudaleni ngenxa sisifo iliso okanye nokuphazamiseka ebuchotsheni. Nystagmus angaba negalelo ukuvela:

• abazizidalwa ngokukhula intrauterine ;
• ingane ezalwe;
• ukuphatheka sokuzalwa;
• izifo iliso (hyperopia, ukubona, strabismus, muscular semehlo, Umthambo-luvo yoma, astigmatism);
• zombini bekhubazekile kwaye ziyafikelelwa ongaboniyo;
• izilonda ezibuhlungu kunye ezosulelayo zobuchopho (ibhulorho, kwiCerebellum, posa, lo ngokungqalileyo gyrus wesibini Oblongata Medulla).

Ukongeza, iintshukumo ngokuzenzekelayo ye iliso inokuba ingabangelwa nobetho okanye multiple. Uphuhliso nystagmus angadala kakubi kweziyobisi kunye notywala. Loo mithi "Amiodarone", "primidone" barbiturates "Phenytoin" "Fluorouracil", "Carbamazepine" nalo negalelo imbonakalo sifo. Kwezinye iimeko, izizathu livela uthathwa iimeko uxinezeleko.

nystagmus azalwa nayo. Yintoni na?

Nystagmus ukuze aphuhlise kwisiqalo iingxaki ezinxulumene zizigulo zemithambo okanye izifo enkqubo olubonakalayo yabantu. nystagmus azalwa i iintshukumo iliso okungaqhelekanga, wabonakalaliswa, ukusukela nje kwixesha lokuzalwa.

Inokuba ukuphuhlisa ngenxa leengxaki kwezakhiwo zobuchopho subcortical (oculomotor, ezibonwayo, vestibular). acuity ebonwayo nystagmus ilifa iziphene ixhomekeke awo kunye amaza iintshukumo vibrational kunye vukele iphantsi kakhulu. Njengoko umthetho, esi sifo kudityaniswe amanxeba somgquba inkqubo olubonakalayo: utshintsho sisiba mandundu le fundus, yoma optic kunye ongaboniyo olusebenzayo. Amaninzi ukuthi kuziveza ngenyanga yesibini okanye yesithathu zobomi. nystagmus Acquired - ntoni na? Kuyinto i makhwiniba oculomotor ukuba kwenzeka ngalo naliphi na ixesha ngethuba ubomi ukuphazamiseka semithambo ekhoyo, iinkqubo ukudumba okanye neoplastic kwiindawo ezahlukeneyo zobuchopho. Esi sifo kunokwenzeka yaye ngenxa ukonzakala entloko, ukusebenzisa kakubi iziyobisi, iziyobisi, utywala. pathology Acquired wohlulwe nystagmus ezizenzekelayo okubangelwa ukuphazamiseka ze izixhobo vestibular, ufakelo kunye Optokinetic.

Types oculomotor zokugula

Kukho ukuhlelwa eziliqela nystagmus. Le typology lokuqala isekelwe kwindlela intshukumo oscillatory. Kukho ezi ndidi zilandelayo:

• nystagmus oxwesileyo (intshukumo eye sibhekiswe ukusuka ekhohlo ukuya ekunene);
• nystagmus nkqo (iintshukumo eye phezulu kwaye phantsi);
• nystagmus oxwesileyo (intshukumo oxwesileyo);
• nystagmus ukujikeleza (eye intshukumo isangqa).

Ulwahlulo yesibini yakhela phezu umlinganiswa kweentshukumo amehlo. Lubonakala pendular nystagmus uniform iintshukumo tangential ke amehlo, nesantya yabo kumacala omabini kuyafana yaye kade. nystagmus ezixhuzuxhuzulayo luphawulwa intshukumo olucothayo kwamehlo kulo naliphi icala kunye imbuyekezo ngokukhawuleza eyadlulayo. Mixed ubandakanya zombini iindidi: tolchkoobrazny kunye pendulum. Ulwahlulo wesithathu ibandakanya uhlobo ukwahlukana ekhombisa: a ecacileyo (ziphawulwe ngokusisigxina) kunye efihliweyo (nasisihlo intshukumo olungalawulwayo xa ukuvala amehlo kabani).

iinkqubo zokuxilonga ukuze kugqitywe nystagmus kunye nonyango kwezifo

Nayiphi ngugqirha iimviwo ze isigulane liya kuba nako ukumisela nystagmus ngokulula kwi intshukumo ethile eye ngokuzenzekelayo. Kodwa ukufumanisa ingcambu unobangela sifo kufuneka uphando ngakumbi. Okokuqala, lo zamehlo uya kumisela acuity ezibonwayo, imeko retina kunye fundus, enze uhlolo lokusebenza lwe-luvo optic kunye nenkqubo oculomotor. Kamva, isigulana siya kuthunyelwa emine ukuze bangenele inkqubo yoxilongo lwezilwanya: EEG, MRI kunye Echo-EG. Emva kokuchaza ingcambu unobangela wabelwa unyango ngamayeza nokunyanga. owaqaliswa ngokususa esi sifo engundoqo yintoni unobangela nystagmus (umzekelo, ukulungiswa: astigmatism, hyperopia, ukubona). Ukongeza, kuqesha vasodilating iziyobisi kunye neevithamini kwezihlunu abangondlekanga kunye retina. Ukuba kuyimfuneko, ukomeleza izihlunu buthathaka, okanye, icala, buthathaka ngamandla kakhulu isigulane zizakuboniswa kwegazi, likuvumela ukuba bayeke iimpawu ze-nystagmus sifo. Treatment ngu utyando kuya kunciphisa awo kunye amaza iintshukumo vibrational le amehlo. Kuyo nayiphi na imeko, ezi ngezifo unyango oculomotor kuthatha ixesha elininzi.
