Nystagmus

INystagmus ligama elichaza intshukumo ekhawulezayo, engalawulekiyo yamehlo anokuba:

• Icala kwicala (i-nystagmus ethe tye)
• Phezulu nasezantsi (nkqo inystagmus)
• Rotary (rotary okanye torsional nystagmus)

Kuxhomekeke kwisizathu, ezi ntshukumo zinokubonakala emehlweni okanye kwiliso elinye.

I-Nystagmus inokuchaphazela umbono, ibhalansi kunye nokulungelelanisa.

Ukuhamba kwamehlo okungazibandakanyi kwe-nystagmus kubangelwa ngumsebenzi ongaqhelekanga kwimimandla yengqondo elawula intshukumo yamehlo. Inxalenye yendlebe yangaphakathi evakalelwa kukuhamba kunye nokuma (i-labyrinth) inceda ukulawula ukuhamba kwamehlo.

Zimbini iindlela zenystagmus:

• I-infantile nystagmus syndrome (INS) ikhona ekuzalweni (kokuzalwa).
• I-nystagmus efumanekayo ikhula kamva ebomini ngenxa yesifo okanye ukwenzakala.

I-NYSTAGMUS EBEKELWEYO (usana lwe-nystagmus syndrome, okanye i-INS)

I-INS ihlala iphakathi. Ayibi nzima, kwaye ayihambelani nayiphi na ingxaki.

Abantu abakule meko bahlala bengazi ngokuhamba kwamehlo, kodwa abanye abantu banokubabona. Ukuba iintshukumo zinkulu, ubukhali bombono (ukubonwa kakuhle) kunokuba ngaphantsi kwama-20/20. Utyando lunokuphucula umbono.

I-Nystagmus inokubangelwa zizifo ezizalwe liliso. Nangona oku kunqabile, ugqirha wamehlo (ophthalmologist) kufuneka avavanye nawuphina umntwana one-nystagmus ukujonga isifo seso.

KUFUNEKE NYSTAGMUS

Unobangela oqhelekileyo wokufunyanwa kwe-nystagmus ngamachiza athile okanye amayeza. I-Phenytoin (i-Dilantin) - iyeza lokuthomalalisa umzimba, utywala obuninzi, okanye naliphi na iyeza lokuthambisa linokuphazamisa ukusebenza kwelabyrinth.

Ezinye izizathu zibandakanya:

• Ukwenzakala entloko kwiingozi zeemoto
• Ukuphazamiseka kwendlebe kwangaphakathi njengelebyrinthitis okanye isifo seMeniere
• Ukubetha
• I-thiamine okanye i-vitamin B12

Nasiphi na isifo sobuchopho, esifana ne-multiple sclerosis okanye izicubu zobuchopho, sinokubangela i-nystagmus ukuba iindawo ezilawula ukuhamba kwamehlo zonakele.

Kuya kufuneka wenze utshintsho ekhaya ukuze uncede ngesiyezi, iingxaki ezibonakalayo, okanye ukuphazamiseka kwenkqubo yemithambo-luvo.

Fowunela umboneleli wakho wezempilo ukuba uneempawu ze-nystagmus okanye ucinga ukuba unale meko.

Umboneleli wakho uya kuthatha imbali ngononophelo kwaye enze uvavanyo lomzimba olucokisekileyo, egxile kwinkqubo yeemvakalelo nakwindlebe yangaphakathi. Umboneleli unokukucela ukuba unxibe iigogg eziphakamisa amehlo akho ngenxalenye yoviwo.

Ukujonga i-nystagmus, umboneleli unokusebenzisa le nkqubo ilandelayo:

• Ujikeleza malunga nemizuzwana engama-30, yima, kwaye uzame ukujonga into.
• Amehlo akho aya kuqala athi chu kancinci esiya kwicala elinye, emva koko aya kukhawuleza akhawuleze aye kwelinye icala.

Ukuba une-nystagmus ngenxa yonyango, ezi ntshukumo zamehlo ziya kuxhomekeka kwisizathu.

Unokuba nale mvavanyo ilandelayo:

• Ukuvavanywa kwentloko kwe-CT
• Electro-oculography: Indlela yombane yokulinganisa intshukumo yamehlo usebenzisa ii-electrode ezincinci
• I-MRI yentloko
• Uvavanyo lweVestibular ngokurekhoda ukuhamba kwamehlo

Akukho lunyango kwiimeko ezininzi zesibeleko se-nystagmus. Unyango lwe-nystagmus efunyenweyo luxhomekeke kwisizathu. Ngamanye amaxesha, i-nystagmus ayinakubuyiselwa umva. Kwiimeko ngenxa yamayeza okanye usulelo, i-nystagmus ihlala ihamba emva kokuba unobangela ungcono.

Olunye unyango lunokunceda ukuphucula ukusebenza kwabantu abane-syndrome ye-nystagmus syndrome:

• Iiprism
• Ugqirha olunje nge-tenotomy
• Unyango lweziyobisi kwi-nystagmus yeentsana

Ukuhamba naphambili kokuhamba kwamehlo; Iintshukumo zamehlo ezingafunekiyo; Ukuhamba kwamehlo okukhawulezayo ukusuka kwelinye icala ukuya kwelinye; Iintshukumo zamehlo ezingalawulwayo; Ukuhamba kwamehlo -ukungalawuleki

• I-anatomy yangaphandle yamehlo nangaphakathi
