I-optic nerve atrophy

I-optic nerve atrophy ingumonakalo we-optic nerve. Imizwa ye-optic ithwala izithombe zalokho iso elikubonayo ebuchosheni.

Kunezimbangela eziningi ze-optic atrophy. Okuvame kakhulu ukungahambi kahle kwegazi. Lokhu kubizwa ngokuthi yi-ischemic optic neuropathy. Inkinga ivame ukuthinta abantu abadala asebekhulile. Imizwa ye-optic nayo ingalimala ngokushaqeka, ubuthi, imisebe kanye nokuhlukumezeka.

Izifo zamehlo, njenge-glaucoma, nazo zingadala uhlobo lwe-optic nerve atrophy. Isimo singabangelwa futhi yizifo zobuchopho kanye nesistimu yezinzwa emaphakathi. Lokhu kungafaka:

• Isigaxa sobuchopho
• I-cranial arteritis (kwesinye isikhathi ibizwa ngokuthi i-temporal arteritis)
• I-Multiple sclerosis
• Unhlangothi

Kunezinhlobo ezingavamile ze-hereditary optic nerve atrophy ezithinta izingane nabantu abadala. Kwesinye isikhathi ukulimala ebusweni noma ekhanda kungaholela ekutheni i-optic nerve atrophy.

I-optic nerve atrophy ibangela umbono ukufiphala futhi inciphise inkambu yombono. Amandla okubona imininingwane emihle nayo izolahleka. Imibala izobonakala ifiphele. Ngokuhamba kwesikhathi, umfundi uzobe esehluleka ukusabela ekukhanyeni, futhi ekugcineni, amandla akhe okuphendula ekukhanyeni angalahleka.

Umhlinzeki wezokunakekelwa kwempilo uzokwenza ukuhlolwa kwamehlo okuphelele ukubheka isimo. Ukuhlolwa kuzobandakanya izivivinyo ze:

• Umbono wombala
• I-reflex light yomfundi
• I-Tonometry
• Ubukhali obubukwayo
• Ukuhlolwa kwenkambu yokubuka (umbono ongaseceleni)

Ungadinga futhi ukuhlolwa okuphelele ngokomzimba nezinye izivivinyo.

Ukulimala kwe-optic nerve atrophy akunakuhlehliswa. Lesi sifo esiyisisekelo kufanele sitholakale futhi silashwe. Ngaphandle kwalokho, ukulahleka kombono kuzoqhubeka.

Imvamisa, izimo eziholela ekutheni i-optic atrophy ingelapheka.

Umbono olahlekelwe yi-optic nerve atrophy awutholakali. Kubaluleke kakhulu ukuvikela elinye iso.

Abantu abanalesi simo badinga ukuhlolwa njalo ngudokotela wamehlo onolwazi ngezimo ezihlobene nemizwa. Tshela udokotela wakho ngokushesha nganoma yiluphi ushintsho embonweni.

Izimbangela eziningi ze-optic nerve atrophy azikwazi ukuvinjelwa.

Izinyathelo zokuvimbela zifaka:

• Abantu abadala asebekhulile kufanele babe nomhlinzeki wabo baphathe ngokucophelela umfutho wegazi.
• Sebenzisa izindlela zokuphepha ezijwayelekile ukuvikela ukulimala ebusweni. Ukulimala okuningi ebusweni kungumphumela wezingozi zemoto. Ukugqoka amabhande esihlalo kungasiza ukuvimbela lokhu kulimala.
• Hlela ukuhlolwa kwamehlo konyaka okujwayelekile ukuze uhlole i-glaucoma.
• Ungalokothi uphuze utshwala obenziwe ekhaya nezinhlobo zotshwala ezingahloselwe ukuphuza. I-Methanol, engatholwa otshwaleni obuphekwe ekhaya, ingadala i-optic nerve atrophy emehlweni womabili.
