Yintoni i-nystagmus, indlela yokuchonga nokunyanga

Umxholo

• Ungayichonga njani i-nystagmus
• Izizathu eziphambili
• Unyango lwenziwa njani

I-Nystagmus yintshukumo yamehlo engazibandakanyiyo kunye ne-oscillatory, enokuthi yenzeke nokuba intloko ithe cwaka, kwaye inokubangela ezinye zeempawu, ezinje ngokuba isicaphucaphu, ukugabha kunye nokungalingani, umzekelo.

Ukuhamba kwamehlo kunokwenzeka kwelinye icala ukuya kwelinye, kubizwa ngokuba yi-nystagmus ethe tye, ukusuka phezulu kuye ezantsi, ufumana igama le-nystagmus ethe nkqo, okanye kwizangqa, olu hlobo lubizwa ngokuba yi-rotary nystagmus.

I-Nystagmus inokuthathwa njengesiqhelo, xa isenzeka ngenjongo yokujonga ukuhamba kwentloko kunye nokujolisa kumfanekiso, umzekelo, kodwa inokuthi ithathelwe ingqalelo njenge-pathological xa isenzeka nokuba intloko imisiwe, inokuba sisiphumo I-labyrinthitis, utshintsho lwe-neurological okanye isiphumo secala lamayeza, umzekelo.

Ungayichonga njani i-nystagmus

I-Nystagmus ibonakaliswa ikakhulu kukuhamba ngokungakhathali kwamehlo, okunokuba yinto yesiqhelo okanye ngenxa yemeko ethile yomntu, kwimeko apho ibizwa ngokuba yi-nystagmus yezifo. INystagmus inezinto ezimbini ezenziwayo, enye iyacotha kwaye enye iyakhawuleza. Ukuhamba kancinci kuhamba xa amehlo elandela intshukumo yentloko, egxile kwindawo esisigxina. Xa amehlo efikelela kumda wawo, ukuhamba ngokukhawuleza kubabuyisela kwindawo yokuqala.

Xa intshukumo ecothayo kunye nekhawulezayo isenzeka nokuba intloko imisiwe, intshukumo yamehlo iyaqapheleka, kwaye le meko ibizwa ngokuba yi-nystagmus yezifo.

Ukongeza kwiintshukumo zamehlo ezingafunekiyo, i-nystagmus inokuqatshelwa ngenxa yokuvela kweempawu ezithile, ezinjengokungalingani, isicaphucaphu, ukugabha nokuba nesiyezi.

Izizathu eziphambili

Ngokwesizathu, i-nystagmus inokuhlelwa ngokweendidi ezimbini eziphambili:

1. Nystagmus yomzimba, apho amehlo ahamba ngesiqhelo ukuze ajonge umfanekiso xa sijika iintloko, umzekelo;
2. Nystagmus yezifo, apho intshukumo yamehlo iyenzeka nkqu nasentloko isamile, ngesiqhelo ibonisa ukuba kukho utshintsho kwinkqubo ye-vestibular, eyinkqubo enoxanduva kungekuphela ukuva nokugcina ibhalansi, kodwa nokuthumela iimpembelelo zombane kwingqondo nakwimimandla elawula iintshukumo zamehlo.

Ukongeza kukwahlulahlula ngokwasemzimbeni nangokwe-pathological, i-nystagmus nayo inokuhlelwa njenge-congenital, xa ibonwa kungekudala emva kokuzalwa, okanye ifunyenwe, eyenzeka ngenxa yeemeko ezininzi ezinokwenzeka ebomini, ingoyena nobangela uphambili:

• Isifo seLabyrinthitis;
• Utshintsho lwe-Neurological kwimisipha yamathumba okanye ukubetha entloko, umzekelo;
• Ukuphulukana nombono;
• Ukungabikho kwesondlo, njengevithamini B12, umzekelo;
• Ukubetha;
• Ukusela kakhulu iziselo ezinxilisayo;
• Iziphumo ebezingalindelekanga zamayeza.

Ukongeza, abantu abane-Down syndrome okanye i-albinism, umzekelo, kunokwenzeka ukuba babe ne-nystagmus.

Uxilongo lwenziwa ngugqirha wamehlo ngokujonga ukuhamba kwamehlo, ukongeza ekwenzeni iimviwo ezithile, ezinje nge-electro-oculography kunye nevidiyo-oculography, umzekelo, apho ukuhamba kwamehlo okungazibandakanyi kugcinwa ngexesha lokwenyani nangokuchanekileyo.

Unyango lwenziwa njani

Unyango lwe-nystagmus lwenziwa ngenjongo yokunciphisa ukubakho kwentshukumo yamehlo engazibandakanyi, ngenxa yoko, unyango lwesizathu lunokuboniswa ngugqirha wamehlo, kunye nokunqunyanyiswa kwesiyobisi esinoxanduva lwe-nystagmus okanye ukongezwa kweevithamini kunokucetyiswa, kwenzeka ngenxa yokusilela kwesondlo.

Ukongeza, ugqirha wamehlo unokucebisa ngokusetyenziswa kwamayeza athile anokusebenza ngqo kwinkqubo ye-neurotransmitter, ukongeza ekusebenziseni iilensi zonxibelelwano.

Kwiimeko ezinzima kakhulu, xa intshukumo engazibandakanyiyo ixhaphake kakhulu kwaye isenzeka nokuba ithini na intloko, utyando lunokuba yimfuneko ukutshintsha indawo yemisipha inoxanduva lokuhambisa iliso, ngaloo ndlela kuphuculwe amandla okujonga izinto, kwi ukongeza ekuphuculeni ukubonwa.
