Ekubulaleni luvo oculomotor: Iimpawu

Oculomotor luvo ibhekisa kwiqela luvo exutyiweyo. Siqulathe injini neerhali parasympathetic. Oku kungenxa luvo oculomotor lwenziwa wokuthwala, yandisa, ujikelezo, kunye nezinye iintshukumo lweliso lakho. Kodwa indima yakhe ebalulekileyo kakhulu, kwaye kuphela oku. Eli licandelo kuyimfuneko ezisebenzayo ukusebenza eqhelekileyo le analyzer olubonakalayo luvo kwakhona ibonelela eliqhelekileyo ijwabu intshukumo kunye umfundi reaction ekukhanyeni.

Ekubulaleni luvo oculomotor: iimpawu, wabonakala eziphambili

Kufuneka kuqatshelwe ukuba ukuhlukumeza ekwanti yale luvo kunqabile kakhulu. Nazi ezi iimpawu eziphambili:

• nokungakwazi kwe izihlunu ijwabu eliphezulu kwaye, ngenxa yoko, ukushiywa yayo buso okanye epheleleyo;
• ukungabikho uxhathiso rectus ephezulu nesezantsi elibhalwe ngokumileyo, ngaloo ndlela unako ukubona Exotropia;
• nokungakwazi lwangaphakathi izihlunu rectus yaye ngenxa yoko, kokuvela lo mkhuba ghosting (umbono kabini);
• ukungabikho impendulo umfundi ekukhanyeni;
• ukuhlukunyezwa innervation imisipha lwangaphakathi kwaye ngenxa yoko, i ukungakwazi ukuqhelana amehlo imigama ezahlukeneyo kulo ezithoba;
• akukho ukuncitshiswa izihlunu rectus amehlo omabini, nto ke leyo ebangele akunakwenzeka ukuba babuye amehlo zibe;
• Buze iso ngenxa yokulahleka kwezihlunu ngaphandle, oku kuqinisekisa ukuba kukho ekubulaleni luvo oculomotor.

Kakhulu, zonke ezi mpawu zidityaniswe kunye neempawu ezihamba ezibangela kwekhono Imisonto luvo lula, kufutshane iqela izihlunu kunye namaziko.

uxilongo iimpawu

Ukuba usindwa zonke Imicu luvo oculomotor, ngokubonakala oku Kucacile kangangokuba kungabikho mathandabuzo inkcazelo uxilongo akubangeli. Oku kuqala ptosis (netshiki ijwabu phezulu), mydriasis, ecaleni ukhozo lweliso ngaphandle kwaye phantsi.

Noko ke, ngokufuthi kukho imidibaniso ezahlukeneyo ptosis kunye umfundi komlomo, kwakunye naziphi na ezinye izifo ezibangelwa paresis kwezihlunu. Kwiimeko ezinjalo, sinako ukuthetha soyisa ngendlela kwisigaba sokuqala Imicu luvo oculomotor, kunye nezinye iintshukumo zokwaphulwa kwemithetho kunokwenzeka ezinxulumene imizimba. Ndihlangule sifo ngexesha nangokuchanekileyo kwiimeko ezinjalo kunzima kakhulu ngakumbi.

Izizathu kokoyiswa, indima loxilongo ngexesha kunye nonyango

Izizathu eziphambili ezibangela ekubulaleni luvo oculomotor zezi:

• ukuphatheka;
• isifo neuroinfec-;
• yamathumba ingqondo umyalezo ezahlukeneyo;
• pnevrizma iimpahla palsy;
• diabetes;
• stroke.

Noko ke, amaxesha amaninzi kubangela buso okanye epheleleyo kwintshabalalo nuclei okanye imicu oculomotor luvo kuhlala kuphela vekeleke xona. Ngokufanayo, azinako ukusekwa bona. Umzimba womntu - inkqubo entsonkothileyo kakhulu, kwaye fundanga ngokupheleleyo, kodwa siqiniseke ngokupheleleyo ukuba ukuphazamiseka enye inxalenye yayo kwekhonkco adlulisele kuye kwabanye amalungu, imizwa kunye nezihlunu.

Umzekelo, peripheral le oculomotor luvo zodwa kunqabile kakhulu, kwaye kaninzi njengokubonisa esihamba kunye zezifo ezingapheliyo okanye enaso, ngokunjalo kuba ngenxa yokwenzakala kwengqondo siganeko kunye nangezilonda. Ngonyango olufanelekileyo kwaye ngexesha esi sifo zinokudluliselwa ngaphandle iingxaki kunye ezilwenza.

Ukuba kurhanelwa neuropathy le luvo oculomotor, qiniseka ukuba izifundo ze iimvavanyo, kuquka igazi CNS zomzimba. Kuphela emva kokuba iziphumo kunye nasekuziqiniseni kwam Uxilongo banikwe unyango kwaye kuyimfuneko ukuba enze iimvavanyo ngokuphindaphindiweyo.

lokufunyaniswa kwesifo

Ukuba kukho urhano ye ukugxojwa imisebenzi luvo oculomotor, ukuqinisekisa okanye ukuphika oku, kwaye kananjalo ukuba achaze isizathu ngokwenene ukulahlwa kunokwenzeka kuphela ukwenza baphethwe ezikumgangatho ophezulu. Kaninzi oku kwenziwa zamehlo, yaye kuphela kwezinye iimeko, ukuba uphethwe uyathandabuza, ingcebiso engaphezulu umiselwa emine.

Uxilongo kunye nokuhlolwa iliso eyenziwe kunye nezixhobo zekhompyutha mihla, kwakunye ngokusebenzisa iintlobo zovavanyo ezizodwa. Ngenxa yoko, emva kokuba wenza oluntsonkothileyo isigulane ukuba yintoni na unobangela.

Kwakhona, ukongeza kwiinkqubo eziqhelekileyo kwenziwa ukujonga imeko ye fundus, inkcazelo yomgangatho, ukushukumiseka Iliso Ubhaqo abasabela ngayo umfundi ekukhanyeni yenziwa MRI kunye angiography. Ukuba umyalezo ayenziwanga ukubonakala ngokupheleleyo, kwanokuba ke sisilonda esidumbileyoesingaphakathi le-luvo oculomotor baqinisekisa esweni nomonde ngokuyimfuneko ngokuqhubekayo, kwakunye nokuqhuba uphando ngokuphindaphindiweyo.

esweni abasisigxina welungu ochaphazelekayo - kuyimfuneko zonyango

Oku kubaluleke kakhulu, kuba ukuchongwa yokuqala nangakumbi ukuqhubeka kwesifo, kunye nokuhlolwa rhoqo lokutshona kunyango ebekiweyo zibaluleke kakhulu kuba yonke imeko ngeliso kunye lonke ikamva ebomini bomntu. Hi xikombiso, le neuritis oculomotor luvo kwiimeko ezininzi uba namandla entle kwimeko ukuthotyelwa zonke iimfuno yomguli, Noko ke, unyango wenziwa kuphela phantsi kweliso lomgadi ziingcali.

Inzululwazi ukuma ngxi, yaye omnye esandukubakho iindlela ezintsha zokufumanis a ukuskena superposition kagesi kwemisipha iliso nokuvavanya umsebenzi wabo ezisebenzayo. Ngale ndlela kunciphisa ngokubonakalayo ixesha ekhoyo ukuchonga oonobangela neziphithiphithi, kwaye kusenokwenzeka ukuba ukuqala unyango ngokukhawuleza baze bazuze iziphumo ezihle.

Eyona ndlela isebenzayo zonyango

Xa kukho urhano ye ukugxojwa imisebenzi luvo oculomotor kunokwenzeka, isigulane nangoko Siyaleza ukwenza imithambo ukomeleza izihlunu unoxanduva intshukumo amalungu lokubona. Kakade ke, zama kangangoko unako ukuqinisa oku kakuhle, kungabi kuphela xa kwakukho iingxaki, kodwa ngenxa nokuthintela, kodwa oku kuphela kanye ekuqaleni yemposiso. Ukuba yahlaselwa kakhulu inxalenye enkulu, le mithambo aziyi kukunceda ukuze achache, nangona kukho inxalenye ebalulekileyo unyango, kusenjalo nangoku.

Isiphakamiso zixhaphakileyo olandelayo abafumana iivithamini ezifanelekileyo kunye namayeza afanelekileyo, isiphumo apho kwakhona ngqo ikukukhuthaza izihlunu ocular kwaye ubuyisele ukusebenza kwawo. Kusenokuba iivithamini ezizodwa, iliso amathontsi, iiglasi, amabhandeji, ezenza iliso nomonde ukuba asebenze ngaphezulu ngenkuthalo.

Luxhaphakile namhlanje iinkqubo ezikhethekileyo zekhompyutha. Oku ikakhulu umfanekiso ekuthiwa-yesitiroyo.

Ukusetyenziswa iinkqubo zekhompyutha kwi unyango ukuphazamiseka misebenzi eye kwezihlunu

Oku kubonakaliswa ukuba xa ukubonisa imifanekiso lukaloliwe izihlunu esweni yaye kuphucula igazi kubo. Ngeli xesha, kwimithambo- zinoxanduva ukusebenza okuqhelekileyo iliso, ibekwe ngobume kwempixano esiba, nabo bonke oovimba umzimba ejoliswe iliso kubo, ngenxa yokuba uninzi namanye amalungu ngexesha ukubukela bekhululekile kwaye musa kufuna ingqalelo enjalo.

ngokwenene Stereopicture abe nombono entle kakhulu, kodwa ke zinokusetyenziswa kuphela emva kokubonisana ugqirha. Eneneni, kwezinye iimeko, ukuba nje ilikhubalo, yaye abanye - kunokubangela umonakalo noqhekeko.

zonyango zangoku

Ukuba emva noxilongo eziliqela macala edibanayo baqinisekisa ukuba wambetha oculomotor luvo, unyango kufuneka ziqalwe ngaphandle kokulibazisa. Elinye icala elihle eqinisekisiwe kwaye yasetyenziswa zamehlo nesisebenzayo kwiminyaka embalwa edlulileyo kukuba unyango kunye elektrofarez izitshanguba 1.5% neuromidin.

It ikhutshwa phandle superimposing ezintathu setyhula ezahlukeneyo enye kwenye kwingingqi i electrode, ezimbini apho abe ezincinci Orbital kummandla isikhumba ijwabu ongentla uvale amehlo. Ixhume kwabo i electrode indawo wire olusabufolokhwe enkulu, nto leyo ibekwe kummandla Nape zentloko yesigulane.

Ngethuba lokuqhuba kwale nkqubo kwisifundo imithi iiseshoni 15 wabamba yonke imihla - imizuzu eli-15-20. Le ndlela ivumela abantu ekujoliswe kwaye ekuhlaleni ziyayiphembelela leesynapse ezineziphene neuromuscular lweliso lakho, yaye imithambo oculomotor isakhiwo yenyukliya.

Xa ahlinzwe kuyimfuneko

Xa uninzi amatyala ukuqhuba ungenelelo olukhawulezileyo yotyando. Ijoliswe bayeke oonobangela esi sifo. Kwiimeko ezininzi, ngenxa izakhono lwemisebenzi amayeza namhlanje ziqhutywa phantsi zomzimba zasekuhlaleni, yaye ujika ngaphandle esibhedlele.

Nayiphi kwekhono kwemisipha iliso nezifundo ezahlukeneyo yokwenzakala ye-luvo oculomotor nemiphumela emibi kakhulu. Ukuba iliso omnye uqala ukubona embi, ezona yesibini uzama ukubuyisela le ukuhlukunyezwa. Kwimeko apho eqala ukuphuhlisa ptosis, ebekwe ecaleni izihlunu ngelixa esenza ngenkulungwane kokususa yedwa. Yiyo loo nto Kucetyiswa ukuba iimviwo rhoqo zamehlo ukususela kanye ukuzalwa komntwana, kwaye nasiphi na isiganeko ukuba ukuphoswa kubo. Oku kubaluleke kakhulu, kuba kuphela yokuthintela isifo ngexesha eqinisekisa isiphumo kakhulu kangangoko.
