Wake wazizwa amehlo akho ehambahamba emuva naphambili, phezulu naphansi, noma ezindilinga, ngokungalawuleki? Mhlawumbe uzizwa sengathi izinto ozibukayo ziyathuthumela noma ziyanyakaza. Lokhu kungaba yinto eyesabekayo. Kodwa ungakhathazeki. Namuhla sizokhuluma ngalesi simo. Kwezokwelapha, sikubiza ngokuthi i-nystagmus. Ake sibheke ukuthi iyini, kungani yenzeka, nokuthi yini ongayenza ngayo.
Kalula nje, iyini i-Nystagmus?
Kalula nje, i-Nystagmus iwukunyakaza okungalawuleki, okusheshayo, nokuphindaphindayo kwamehlo ethu. Lokhu kungenzeka esweni elilodwa noma kuwo womabili amehlo. Lokhu kunyakaza kwamehlo kungaba ngezindlela ezahlukene.
- Uhlangothi nohlangothi: Amehlo ahamba ngokushesha ukusuka kolunye uhlangothi kuya kolunye, njengezihlanzi zemoto. Lokhu sikubiza ngokuthi i-nystagmus evundlile.
- Ukukhuphuka nokuhla: Ukunyakaza okusheshayo kwamehlo phezulu naphansi. Lokhu kuyi-nystagmus eqondile.
- Isiyingi: Ukunyakaza okubonakala sengathi kwenza amehlo ahambe ngendlela ejikelezayo. Lokhu kubizwa ngokuthi i-rotary nystagmus.
Iphethini yalezi zinyathelo ingahluka futhi.
- I-Jerk Nystagmus: Lokhu kuwukunyakaza okusheshayo nokungazelelwe kwamehlo kusuka kolunye uhlangothi kuya kolunye, njengokungathi uzama ukulungisa iphutha.
- I-Pendular Nystagmus: Lokhu kwenzeka lapho amehlo womabili enyakaza eceleni ngesivinini esifanayo, njenge-pendulum yewashi elidala elijika liye phambili naphambili.
Lokhu kunyakaza okungalawulwa kwamehlo kungabangela izinkinga ngokubona , ukuqonda okujulile , ukulinganisela komzimba , kanye nokuxhumana kwezitho .
Yiziphi izinhlobo eziyinhloko ze-nystagmus?
I-Nystagmus ingathinta kokubili izingane kanye nabantu abadala. Siyihlukanisa ibe izinhlobo ezimbili eziyinhloko, kuye ngokuthi lesi simo siqala nini.
1. I-Nystagmus yokuzalwa noma yobuntwana
Lolu uhlobo oluvame kakhulu. Njengoba igama lisho, lungaba khona lapho luzalwa noma lukhule ezinyangeni ezimbalwa zokuqala zokuphila, ngokuvamile phakathi kwamasonto ayisithupha nezinyanga ezi-3. Ngezinye izikhathi lungaba yifa. Kodwa-ke, asikho isizathu esicacile salokho. Izingane ezine-nystagmus yokuzalwa zinalo lolu hlobo emehlweni womabili. Futhi amehlo avame ukuhamba ukusuka kolunye uhlangothi kuya kolunye. Inkinga enkulu yalezi zingane ukubona okufiphele .
2. I-Nystagmus Etholakale
Lolu hlobo lungakhula kamuva empilweni, ngokuvamile kunoma yimuphi ubudala ngemva kwezinyanga eziyisithupha. Luvame kakhulu kubantu abadala. I-Acquired Nystagmus ivame ukuba uphawu lwesinye isimo esiyisisekelo. Lokhu kusho ukuthi kukhona umonakalo ebuchosheni bakho, emehlweni , noma ezindlebeni.Lokhu kungabangelwa yisimo sezokwelapha esithinta amehlo. Ngezinye izikhathi kungabangelwa nokusetshenziswa kotshwala noma izidakamizwa. Into eyodwa abantu abadala abanalolu hlobo lwe-nystagmus abavame ukuyisho ukuthi, "Dokotela, izinto engizibonayo zibonakala zihamba, sengathi ziyathuthumela."
I-Spasmus Nutans uhlobo lwe-Acquired Nystagmus oluvela ezinganeni. Ngokuvamile luvela ezinganeni eziphakathi kwezinyanga eziyi-6 neminyaka eyi-3. Kodwa izindaba ezinhle ukuthi lolu hlobo luvame ukuba ngcono ngokwalo phakathi kweminyaka eyi-2 neyi-8 ngaphandle kokwelashwa.
Ingabe lesi simo sibucayi?
Lena inkinga abantu abaningi abanayo. I-Nystagmus iyodwa ayiyona ingozi. Kodwa-ke, ingaba uphawu lwezinye izimo ezimbi kakhulu, ikakhulukazi izimo ezihlobene nobuchopho. Isibonelo:
- Isifo sohlangothi
- Isimila sobuchopho
- Ukulimala ekhanda
- Ubuthi
- Izifo zokuvuvukala zobuchopho
Ngakho-ke, nakuba uphawu lwe-nystagmus ngokwalo lungeyona ingozi, isimo sezokwelapha esibangela lokhu singaba sibi kakhulu. Ngakho-ke, kungcono ukungalokothi uzishaye indiva lezi zimpawu.
Ziyini izimpawu ze-nystagmus?
Uphawu oluyinhloko ukunyakaza kwamehlo okungalawuleki esixoxe ngakho ekuqaleni. Kodwa-ke, kungase kube nezinye izimpawu eziningana kuye ngokuthi imbangela iyini.
| Isibonakaliso | Incazelo elula |
|---|---|
| I-Oscillopsia | Umuzwa wokuthi izwe elikuzungezile liyathuthumela futhi liyadlidliza. Kuzwakala sengathi izwe liyadlidliza ngisho noma umile. |
| Umbono ofiphele | Ngenxa yokuthi amehlo ahlala ehamba, kunzima ukugxila isithombe endaweni eyodwa. Ngakho-ke, umbono awucacile. |

| I-Vertigo | Isiyezi esinzima esizwakala sengathi uyajikeleza futhi uyajikeleza. |
| Ukuzwela ekukhanyeni | Ubunzima bokugxila ekukhanyeni okukhulu kanye nobunzima bokubona ebumnyameni. |
Kungani lokhu kwenzeka? Yiziphi izimbangela ze-nystagmus?
Ukuze uqonde lokhu, udinga ukuba nombono omncane wokuthi amehlo ethu ahamba kanjani. Ukunyakaza kwamehlo ethu kulawulwa uhlelo oluyinkimbinkimbi kakhulu. Lokhu kuhilela ubuchopho , amehlo , kanye nohlelo lwe-vestibular, okuyingxenye yendlebe yangaphakathi elawula ibhalansi . Kufana 'nesiqinisi sesithombe' ekhamera enhle. Ngisho nalapho sishukumisa amakhanda ethu, lokho esikubonayo kuhlala kuzinzile ngenxa yokusebenza kwalolu hlelo. Ku-nystagmus, kunenkinga ndawana thize kulokhu.
Nazi ezinye zezimbangela eziyinhloko ze-nystagmus:
- Izinkinga ngokuthuthukiswa kobuchopho noma kwamehlo.
- Izifo ze-retina noma i-optic nerve.
- Izinkinga zokulinganisela indlebe yangaphakathi, njenge- Benign Paroxysmal Positional Vertigo (BPPV) kanye nesifo sikaMénière .
- Isifo sohlangothi.
- Isimila sobuchopho.
- Ukulimala esweni noma ekhanda.
- Ukusetshenziswa kotshwala noma izidakamizwa ezithile.

- Izinkinga zamehlo ezinganeni ezincane. Isibonelo, izimo ezifana ne-strabismus kanye ne-cataracts.
Ngezinye izikhathi asikho isizathu esicacile esingatholakala salokhu. Siyibiza ngokuthi i-Idiopathic Nystagmus .
Ungakubona kanjani lokhu?
Uma unezimpawu ze-nystagmus, kufanele uqale uhlolwe udokotela wamehlo.Kungenzeka. Uzohlola amehlo akho ngokucophelela, abuze ngezimpawu zakho, futhi ahlole ezinye izimo zamehlo ezingase zihlobane nalokhu.
Kodwa ukuze uthole imbangela, kungadingeka ukuthi ubonane nabanye ochwepheshe.
- Udokotela Wezinzwa: Hlola inkinga ehlobene nobuchopho.
- Udokotela we-Otorhinolaryngologist noma udokotela we-ENT: Hlola izinkinga zokulinganisela endlebeni yangaphakathi.
Ukuze uthole imbangela eqondile, ungenza izivivinyo ezilandelayo:
- Ukuhlolwa okuphelele kwezinzwa.
- Ukuhlolwa kwendlebe.
- Ukuhlolwa okukhethekile okuqopha ukunyakaza kwamehlo, njenge -Electronystagmography (ENG) kanye ne-Video-nystagmography (VNG) .
- Ukuhlolwa kokubona ubuchopho, njenge -CT scan (i-Computed Tomography scan) noma i-MRI (i-Magnetic Resonance Imaging) .
- Ukuhlolwa kwezakhi zofuzo ukuze kutholakale amaphutha ezakhi zofuzo abangela i-nystagmus yokuzalwa.
Yiziphi izindlela zokwelapha i-nystagmus?
Ukwelashwa kwalokhu kuncike ngokuphelele embangweni oyisisekelo we-nystagmus. Okusho ukuthi, selapha imbangela eyisisekelo, hhayi nje uphawu.
Ukwelapha isimo esiyisisekelo
Ku-Acquired Nystagmus, uma sibona futhi selapha isimo esiyisisekelo, izimpawu ze-Nystagmus zingase zinciphe noma zinyamalale ngokuphelele. Isibonelo, uma i-Nystagmus ibangelwa inkinga endlebeni yangaphakathi, ukwelashwa lokho kuzonciphisa isiyezi kanye nokudlidliza kwamehlo.
Izibuko noma amalensi okuxhumana
Njengoba ukubona kwakho kuthuthuka, ukunyakaza kwamehlo okusheshayo kungalawulwa ngezinga elithile. Ngakho udokotela wakho angase atuse izibuko noma ama-contact lens. Angase futhi akunike uhlobo olukhethekile lwelensi ebizwa ngokuthi ama-prism lens . Lokhu kunciphisa inani lokucindezeleka amehlo akho okufanele akusebenzele ukuze abone.
Imithi
Kunemithi eminingana engasiza ekunciphiseni izimpawu ze-nystagmus kubantu abadala. Isibonelo, i-Gabapentin , i-Baclofen , ne -Onabotulinumtoxina (Botox®) . Udokotela wakho uzonquma ukuthi le mithi ingakusiza yini.
Ukuhlinzwa kwemisipha yamehlo
Lokhu kwenziwa kaningi kakhulu. Lokhu kuhlinzwa kuhilela ukushintsha indawo yemisipha eshukumisa amehlo. Lokhu kuhlinzwa akukwazi ukwelapha ngokuphelele i-nystagmus, kodwa kungenza kube lula ukuhambisa amehlo. Lokhu kunciphisa inani lokujika nokutshekisa ikhanda lakho ukuze ubone kahle.
Ukuhlinzwa kokulungisa umbono
Uma unenkinga yokubona ibanga nge-nystagmus, i-LASIKUkuhlinzwa nge-laser, njengalokhu, kungaba usizo. Khumbula, lokhu kuhlinzwa ngeke kwelaphe i-nystagmus. Kodwa-ke, njengoba ukubona kwakho kuthuthuka, izimpawu ze-nystagmus zingase zinciphe.
Kufanele ubonane nini nodokotela?
