Nystagmus - kuyini? nystagmus azalwa naso. Nystagmus - ukwelashwa

Ngezinye izikhathi ukukhuluma nomuntu, ungase uphawule ukuthi "run" iso. Kulokhu, ungase ube nomuzwa wokuthi lo muntu akanandaba inkhulumomphendvulwano noma akusho ethemba you. Ubheka kude, ayigxilile ubuso bakho futhi ayisekeli kuchumana ngemehlo. Ngeshwa, abantu abakwazi baziphathe ngale ndlela ngenxa ukwenqena ukuqhuba ingxoxo, kodwa ngenxa yalokho lesi sifo, okuthiwa i-nystagmus. Kuyini, yiziphi izimbangela ngamandla kwalesi sifo, kodwa kungani pho ukuhlolelwa lesi sifo futhi iphathwa? Konke lokhu, thina ukuchaza ngokuningiliziwe kulesi sihloko.

kwencazelo nystagmus

ukubonakaliswa Clinical yalesi sifo abasakwazi njalo, rhythmical, oscillatory ukunyakaza okungalindelekile we zamehlo. Umuntu onalo nystagmus, akuyona ukugxila yisiphi isihloko. Ngeke ngu umzamo ukuqala noma ukumisa ngokuzimele okungalindelekile iso ukunyakaza. Ngokuvamile lesi sifo kuhambisana ukwehla acuity ezibukwayo. Njengoba bekhula, izimpawu nystagmus kungenzeka kancane encishisiwe. Noma kunjalo, noma yisiphi isimo esicindezelayo noma ukukhathala ezinzima ziphinde zikwazi liyochukuluza Ukuwohloka flow yayo. Nystagmus - akukona ukwephuka yezimonyo, njengoba abaningi bacabange, futhi inkinga engathí sina ngempela. Lesi sifo ngokuvamile ehambisana nobutha iziyaluyalu okubonakalayo uhlelo imisebenzi, njengoba zamehlo kweziguli hambisa engalawuliwe, futhi akunakwenzeka ukubona into kahle. Abanye abantu ngenxa nystagmus, isimo ezinye izifo esweni, babe wawuyivelakancane. On wonke, kungaba ngokuphawulekayo konakalise izinga lokuphila, ezempilo kanye nokulinganisela ngokwengqondo nystagmus womuntu. Kuyini, sabuka manje ukuxoxa izimbangela, izimpawu kanye namafomu lingaze lesi sifo.

Izimbangela nystagmus

Lokhu zokugula oculomotor kungabonakala nasemkhakheni kusukela ekuzalweni, kwasebuntwaneni noma avele lapho usukhulile ngenxa isifo iso noma ukungasebenzi zobuchopho. Nystagmus anganikela ukuvela:

• intrauterine retardation ukukhula ;
• umntwana ngaphambi kwesikhathi;
• lokuzalwa ukuhlukumezeka;
• izifo iso (hyperopia, myopia, strabismus, sokuwohloka ngwengwzi, optic nerve yoma, astigmatism);
• kokubili azalwa naso futhi wathola ongaboni;
• izilonda kuhlasimulise futhi ezithathelwanayo yobuchopho (kwebhuloho, cerebellum, pituitary indlala, wesibili frontal gyrus we oblongata medulla).

Ngaphezu kwalokho, ukunyakaza okungalindelekile of iso kungase kubangelwe unhlangothi noma yi-multiple sclerosis. Kutfutfukiswa nystagmus kungase kubangele ukulwa nokusetshenziswa kwezidakamizwa notshwala. izidakamizwa zakhe ezinjengethi, "Amiodarone", "primidone" barbiturates "Phenytoin" "Fluorouracil", "Carbamazepine" futhi kungase kube nomthelela ukubukeka kwalesi sifo. Kwezinye izimo, izizathu ivela khona kubhekwa izimo ezicindezelayo.

nystagmus azalwa naso futhi wathola. Kuyini lokhu?

Nystagmus angagcina ku isizinda izinkinga ezihambisana iziyaluyalu noma izifo zesimiso womuntu ezibukwayo zezinzwa. nystagmus azalwa naso kuyinto iso ukunyakaza normal, ebonakaliswa kusukela kakhulu ekuzalweni.

Kungaba ukuthuthukisa ngenxa zokugula we subcortical izakhiwo ubuchopho (oculomotor, ezibukwayo, vestibular). Visual acuity e lezinceku nystagmus azalwa naso incike amplitude kanye nokuvama ukunyakaza vibrational futhi okungalindelekile liphansi kakhulu. Njengomthetho, lesi sifo kuhlangene izilonda organic kohlelo ezibukwayo: izinguquko esiwohlozayo we fundus, yoma-optic futhi functional ongaboni. Ngokuvamile-ke kubonakala ngenyanga wokuphila wesibili noma wesithathu. nystagmus Kutholiwe - kuyini? Kuyinto kwezinso oculomotor ukuthi singenzeka nganoma isiphi isikhathi phakathi nokuphila semithambo iziyaluyalu ekhona, izinqubo ukuvuvukala noma neoplastic ezingxenyeni ezihlukahlukene zobuchopho. Lesi sifo kungavuka futhi ngenxa yokulimala ekhanda, ukusetshenziswa kwezidakamizwa, izidakamizwa, utshwala. zokugula Kutholiwe sehlukaniswe nystagmus nokuguqulwa kubangelwa iziyaluyalu we vestibular apharathasi, ukufakwa kanye Optokinetic.

Izinhlobo oculomotor zokugula

Kunezinhlobo eziningana nystagmus. I typology wokuqala kusekelwe ohlangothini ukunyakaza oscillatory. Kukhona lezi zinhlobo ezilandelayo:

• nystagmus ovundlile (iso ukunyakaza iqondiswa kusuka kwesokunxele kuya kwesokudla);
• nystagmus mpo (iso ukunyakaza phezulu naphansi);
• nystagmus idayagonali (ukunyakaza idayagonali);
• nystagmus ukujikeleza (iso ukunyakaza kumbuthano).

Ukwahlukaniswa yesibili lakhela phezu uhlamvu ukunyakaza iso. Libhekene pendular nystagmus iyunifomu ukunyakaza tangential we zamehlo, nesivinini zabo zombili izinkomba kuyafana futhi ngempela kancane. nystagmus Jerky libhekene ukunyakaza kancane amehlo ukuphendukela kunoma iluphi uhlangothi futhi ngokushesha ukubuya edlule. Ezixutshiwe kuhlanganisa zombili izinhlobo: tolchkoobrazny kanye pendulum. Ukwahlukaniswa okwesithathu kuhilela ngokwahlukana uhlobo ekhombisa: okucacile (kumakwe unomphela) futhi kufihlwe (okuvela ukunyakaza engalawuliwe lapho ukuvala amehlo).

izindlela zokuxilonga sokunquma nystagmus kanye nokwelashwa kwezifo

Noma yimuphi udokotela ngesikhathi ukuhlola isiguli bazokwazi kalula ukunquma nystagmus esikhuluma ngezinhlobo ezithile okungalindelekile iso ukunyakaza. Kodwa ukuthola imbangela yalesi sifo kudingeka ucwaningo olubanzi. Okokuqala, ophthalmologist eyonquma acuity ezibukwayo, isimo retina kanye fundus, futhi enze ukuhlolwa isebenze we emsipheni optic futhi uhlelo oculomotor. Ngemva kwalokho, isiguli izothunyelwa kudokotela oyisazi sezinzwa ngezindleko alandele izindlela zokuxilonga: Bheka, i-MRI kanye Echo-EG. Ngemva kokuchaza imbangela inikezwe yokwelapha. kwaqala nge kokukhipha isifo oyinhloko onikezwayo uwukuthi imbangela nystagmus (isibonelo, ukulungiswa: astigmatism, hyperopia, myopia). Ngaphezu kwalokho, ukhombe vasodilating izidakamizwa amavithamini for izicubu abangondlekile futhi retina. Uma kudingeka, letfutfukisa imisipha buthaka, noma, Ngakolunye uhlangothi, kuyadamba engahlula isiguli uyoboniswa nokuhlinzwa, uvumela ukumisa izimpawu nystagmus isifo. Ukwelashwa nge ukuhlinzwa kuzonciphisa amplitude kanye nokuvama ukunyakaza vibrational we zamehlo. Kunoma ikuphi, le zokugula ikhambi oculomotor kuthatha isikhathi esiningi.
