Yini i-nystagmus, ukuthi ungayibona kanjani futhi uyiphathe kanjani

• Ungayibona kanjani i-nystagmus
• Izimbangela eziyinhloko
• Yelashwa kanjani

I-Nystagmus ukunyakaza okungazibandakanyi nokukhipha iso, okungenzeka noma ikhanda limile, futhi kungaholela kwezinye izimpawu, njengesicanucanu, ukuhlanza nokungalingani, ngokwesibonelo.

Ukuhamba kwamehlo kungenzeka kusuka kolunye uhlangothi kuya kolunye, kubizwa ngokuthi i-nystagmus evundlile, kusuka phezulu kuye phansi, ukuthola igama le-nystagmus emile, noma kwimibuthano, lolu hlobo lubizwa nge-rotary nystagmus.

I-Nystagmus ingathathwa njengokujwayelekile, uma kwenzeka ngenhloso yokuqapha ukuhamba kwekhanda nokugxila esithombeni, ngokwesibonelo, kepha futhi kungabhekwa njengokugula uma kwenzeka noma ikhanda limile, okungaba umphumela we i-labyrinthitis, ushintsho lwezinzwa noma imiphumela emibi yemithi, ngokwesibonelo.

Ungayibona kanjani i-nystagmus

I-Nystagmus ibonakala ikakhulukazi ngokunyakaza kwamehlo okungahlangene, okungaba okujwayelekile noma ngenxa yesimo esithile somuntu, lapho kubizwa khona ngokuthi i-pathological nystagmus. INystagmus ineminyakazo emibili, eyodwa ihamba kancane futhi eyodwa iyashesha. Ukunyakaza okuhamba kancane kwenzeka lapho amehlo elandela ukuhamba kwekhanda, kugxile endaweni eqondile. Lapho amehlo efinyelela umkhawulo wawo, ukunyakaza okusheshayo kubabuyisela endaweni yokuqala.

Lapho ukunyakaza okuhamba kancane nokushesha kwenzeka ngisho nalapho ikhanda limisiwe, ukunyakaza kwamehlo kuyabonakala kakhulu, futhi lesi simo sibizwa ngokuthi i-pathological nystagmus.

Ngaphezu kokunyakaza kweso okungazibandakanyi, i-nystagmus ingabonwa ngenxa yokuvela kwezinye izimpawu, njengokungalingani, isicanucanu, ukuhlanza nesiyezi.

Izimbangela eziyinhloko

Ngokwesizathu, i-nystagmus ingahlukaniswa ngezinhlobo ezimbili eziyinhloko:

1. I-nystagmus yomzimba, lapho amehlo ahamba khona ngokujwayelekile ukuze agxile esithombeni lapho siphendula amakhanda ethu, ngokwesibonelo;
2. I-nystagmus yezifo, lapho ukunyakaza kwamehlo kwenzeka ngisho nekhanda linganyakazi, okuvame ukukhombisa ukuthi kunezinguquko ohlelweni lwe-vestibular, okuluhlelo olubhekele hhayi kuphela ukuzwa nokugcina ibhalansi, kepha futhi nokuthumela imizwa kagesi ebuchosheni nasezifundeni ezilawulayo ukunyakaza kwamehlo.

Ngaphezu kokuhlukaniswa komzimba nokugula, i-nystagmus nayo ingahlukaniswa njenge-congenital, lapho ibonwa ngemuva nje kokuzalwa, noma ukutholwa, okwenzeka ngenxa yezimo eziningana ezingenzeka kuyo yonke impilo, okuyizimbangela eziyinhloko:

• I-labyrinthitis;
• Izinguquko ze-neurological kumisinga yamathumba noma ukushaya ekhanda, ngokwesibonelo;
• Ukulahleka kombono;
• Ukushoda kokudla okunempilo, njengevithamini B12, isibonelo;
• Unhlangothi;
• Ukuphuza ngokweqile iziphuzo ezidakayo;
• Imiphumela emibi yemithi.

Ngaphezu kwalokho, abantu abane-Down syndrome noma i-albinism, ngokwesibonelo, banamathuba amaningi okuba ne-nystagmus.

Ukuxilongwa kwenziwa ngudokotela wamehlo ngokubuka ukunyakaza kwamehlo, ngaphezu kokwenza izivivinyo ezithile, njenge-electro-oculography kanye ne-video-oculography, ngokwesibonelo, lapho ukunyakaza kwamehlo okungazibophezeli kugcinwa khona ngesikhathi sangempela futhi ngokunembile.

Yelashwa kanjani

Ukwelashwa kwe-nystagmus kwenziwa ngenhloso yokunciphisa ukwenzeka kokunyakaza kwamehlo okungazibandakanyi, ngakho-ke, ukwelashwa kwesizathu kungakhonjiswa ngudokotela wezifo zamehlo, futhi kunganconywa ukumiswa kwesidakamizwa esibhekele i-nystagmus noma ukwengeza amavithamini, lapho kwenzeka ngenxa yokushoda kokudla okunempilo.

Ngaphezu kwalokho, udokotela wamehlo angancoma ukusetshenziswa kwemithi ethile engasebenza ngqo ohlelweni lwe-neurotransmitter, ngaphezu kokusetshenziswa kwamalensi wokuxhumana.

Ezimweni ezinzima kakhulu, lapho ukunyakaza okungazibandakanyi kuvame kakhulu futhi kwenzeka kungakhathalekile ukuthi ikhanda limi kuphi, ukuhlinzwa kungadingeka ukushintsha indawo yemisipha ebhekene nokunyakazisa iso, ngaleyo ndlela kuthuthukiswe ikhono lokugxila ezintweni, ngaphezu kokuthuthukisa ikhono lokubona.
