Nystagmus - chii? Vachiberekwa nystagmus. Nystagmus - kurapwa

Dzimwe nguva kutaura munhu, ungacherechedza kuti akanga "run" ziso. Muchiitiko chino, ungafunga kuti mumwe munhu haasi kufarira nhaurirano kana akasavimba iwe. Iye anotarira kure, haripi tsanangudzo pachiso chako uye haritsigiri mumaziso. Zvinosuruvarisa, vanhu havagoni chetezvo nokuda kusada kutakura pamusoro kukurukura, asi nemhaka chirwere, unonzi nystagmus. Chii, chii vari zvinokonzera chirwere ichi, sei chirwere uye kubatwa? izvi zvose, isu hunonyatsodonongodza munyaya ino.

tsananguro nystagmus

Clinical Kuratidza chirwere ichi vano- kakawanda, rhythmical, oscillatory involuntary kufamba pamusoro eyeballs. Munhu ane nystagmus, haisi kutarisa chero nyaya. Haikwanise nokuda kuedza kutanga kana kumira pasina involuntary ziso kufamba. Kazhinji chirwere achabatsirwa vasanyanye kutarisana acuity. With zera, zviratidzo nystagmus anogona kuderedzwa zvishoma. Kunyange zvakadaro, chero mamiriro ezvinhu anonetsa kana kunyange zvakakomba kuneta aigona zvakare kutsamwisa mumwe Kuipa mvura yacho. Nystagmus - haisi chakaremara zvizorwa, sezvo vakawanda vanofunga, uye dambudziko here chakakomba. chirwere ichi kunowanzoguma zvinetso zviri kutarisana ezvinhu mashandiro, sezvo eyeballs varwere dzisingadzorwi kufamba, uye hazvibviri kuona chinhu zvakanaka. Vamwe vanhu nemhaka nystagmus, pakava nezvimwe zvirwere ziso, vave anenge mapofu. On wose, unogona yekudyidzana kanganisa mararamiro, utano uye zvepfungwa mwero nystagmus kwevanhu. Chii, isu akatarisa zvino kukurukura zvinokonzera, zviratidzo uye symptomatic siyana chirwere.

The zvinokonzera nystagmus

Izvi oculomotor zvokurwara zvinogona kuonekwa kubvira pakuberekwa, muduku kana kuonekwa vakura somugumisiro ziso chirwere kana dysfunction wouropi. Nystagmus anogona kukonzera kwaita:

• intrauterine kukura retardation ;
• munhu vakurumidze mwana;
• nokuberekwa kunotevera;
• zvirwere ziso (hyperopia, myopia, strabismus, retinal dystrophy, optic tsinga atrophy, astigmatism);
• zvose vachiberekwa uye vakatodzidza kutadza kuona zvakanaka;
• zvinorwadza uye zvirwere maronda uropi (zambuko, cerebellum, pituitary shwanu, wechipiri frontal gyrus ari medulla oblongata).

Uyezve, involuntary fambisa ziso kunogona kukonzerwa sitiroko kana nemultiple sclerosis. Kugadzirwa nystagmus kungamutsawo kushandisa zvinodhaka uye doro. mishonga yakadai se "Amiodarone", "primidone" barbiturates "Phenytoin" "Fluorouracil", "Carbamazepine" anogona kubatsira pakuonekwa chirwere. Mune zvimwe zviitiko, zvikonzero parinowanika anonzi anoshungurudza ezvinhu.

Vachiberekwa uye vawana nystagmus. Chii?

Nystagmus anogona kuva pamusoro pakanyorwa matambudziko chokuita chetsinga zvirwere kana zvirwere kwevanhu kuona hurongwa. Vachiberekwa nystagmus chinhu zvemamiriro ziso kufamba, kwakaratidzwa kubva pakuzvarwa.

Inogona kuva somugumisiro zvokurwara nokuda subcortical pfungwa zvivako (oculomotor, kutarisana, vestibular). Visual acuity mu nhaka vachiberekwa nystagmus kunobva amplitude uye kakawanda pamusoro vibrational kufamba uye involuntary yakaderera chaizvo. Kazhinji, chirwere unobatanidzwa pamwe Organic maronda ari kutarisana ezvinhu: chinopedza kuchinja kubva fundus, optic atrophy uye dzichipfekeka kutadza kuona zvakanaka. Kakawanda chinoratidza pacharo rechipiri kana wechitatu mwedzi upenyu. Vawana nystagmus - chii? Inguva oculomotor abnormalities anogona kuitika chero nguva mukati upenyu huripo vascular zvirwere, anogumbura kana neoplastic pezvakaitwa munzvimbo dzakasiyana-siyana uropi. chirwere ichi chinogona kuitika uye nokuda kukuvara mumusoro, kushandisa zvinodhaka, zvinodhaka, doro. Vawana zvokurwara rakakamurwa vaingoerekana nystagmus kunokonzerwa zvinetso zviri vestibular midziyo, chokugadza Optokinetic.

Types oculomotor zvokurwara

Kune classifications wandei nystagmus. The typology wokutanga anobva kutungamirirwa oscillatory kufamba. Kune marudzi anotevera:

• chinjikira nystagmus (ziso kufamba inoendeswa kubva kuruboshwe kuenda kurudyi);
• mira nystagmus (ziso kufamba uye pasi);
• nystagmus diagonal (diagonal mafambiro);
• rotational nystagmus (ziso kufamba mudenderedzwa).

The kupatsanura wechipiri achivaka pamusoro hunhu ziso masangano. Ichazivikanwa pendular nystagmus yunifomu tangential fambisa pakati eyeballs, uye dzichimhanya mune vose kumativi ndiro uye zvikuru kunonoka. Jerky nystagmus kunoratidzwa kunonoka kufamba kwemaziso chero mirayiridzo uye nokukurumidza kudzoka kare. Mixed kunosanganisira mhando: tolchkoobrazny uye zvakavamba kuchinja. Wechitatu kupatsanura kunosanganisira kuparadzana mhando kuratidzirana: zvakajeka (mavara zvachose) uye zvakavanzika (panowanikwa dzisingadzorwi kufamba kana kuvhara maziso omunhu).

Chirwere nzira nokuti kusarudza nystagmus uye mabatiro zvirwere

Chero chiremba ari kuongorora murwere achagona kuona nystagmus nyore dzakananga involuntary ziso kufamba. Asi kuziva chinokonzera chirwere vanoda zvikuru tsvakurudzo. Chokutanga, ophthalmologist achasarudza nokuona acuity, mamiriro ezvinhu the retina uye fundus, uye kuita vakaongorora kushanda ari optic etsinga uye oculomotor gadziriro. Zvadaro, murwere achatumirwa chiremba wetsinga narwo chirwere ezvinhu: eeg, MRI uye Echo-EG. Ataura kuti dzinde iri kupiwa yokurapwa. kutanga kwayo pamwe kubvisa zvinokonzera chirwere ndicho chikonzero nystagmus (somuenzaniso, nokururamiswa: astigmatism, hyperopia, myopia). Uyezve, gadzai vasodilating zvinodhaka uye mavhitaminzi kuti zvinyama muviri uye the retina. Kana zvakakodzera, simbisa simba tsandanyama, kana, Ukuwo, simba wo kwakaderera murwere kucharatidzwa uye kuvhiyiwa, rinobvumira kumisa zviratidzo chirwere nystagmus. Treatment nokuda Kuvhiya kuchaderedza ari amplitude uye kakawanda pamusoro vibrational kufamba pamusoro eyeballs. Chero zvazvingava, mushonga oculomotor zvokurwara anotora nguva yakawanda.
