I-atrophy ye-optic yentsholongwane

I-optic nerve atrophy ngumonakalo kwi-optic nerve. Imithambo-luvo ye-optic ithwala imifanekiso yento ebonwa liliso kwingqondo.

Zininzi izinto ezibangela ukuba i-optic atrophy. Eyona nto ixhaphakileyo kukuhamba gazi okungalunganga. Oku kubizwa ngokuba yi-ischemic optic neuropathy. Ingxaki ihlala ichaphazela abantu abadala. Iimbilini ze-optic nazo zingonakaliswa ngumothuko, i-toxins, i-radiation kunye ne-trauma.

Izifo zamehlo, ezifana ne-glaucoma, nazo zinokubangela uhlobo lwe-optic nerve atrophy. Imeko inokubangelwa zizifo zobuchopho kunye nenkqubo ye-nervous system. Oku kunokubandakanya:

• Ithumba lobuchopho
• I-cranial arteritis (ngamanye amaxesha ibizwa ngokuba yi-tempter arteritis)
• Isifo sokugubhuka
• Ukubetha

Kukwakho neendlela ezinqabileyo ze-atrophy yelifa elichaphazela abantwana kunye nabantu abadala. Ngamanye amaxesha ukulimala ebusweni okanye entloko kunokubangela i-optic nerve atrophy.

I-optic nerve atrophy ibangela umbono ukuba unciphise kwaye unciphise intsimi yombono. Ukukwazi ukubona iinkcukacha ezintle kuya kulahleka. Imibala iya kubonakala ngathi iphelile. Ixesha elingaphezulu, umfundi uya kuba nakho kancinci ukusabela ekukhanyeni, kwaye ekugqibeleni, amandla akhe okuphendula ekukhanyeni anokulahleka.

Umboneleli wezempilo uya kwenza uvavanyo olupheleleyo lwamehlo ukukhangela imeko. Uviwo luya kubandakanya iimvavanyo:

• Umbono wombala
• Ukukhanya kwesibane somfundi
• Ithemetri
• Ubunzima bokubonakalayo
• Indawo ebonakalayo (umbono wecala) kuvavanyo

Unokufuna uvavanyo olupheleleyo lomzimba kunye nolunye uvavanyo.

Ukonakala kwe-optic nerve atrophy akunakubuyiselwa umva. Isifo esisisiseko kufuneka sifumaneke kwaye sinyangwe. Ngaphandle koko, ukulahleka kombono kuya kuqhubeka.

Rhoqo, iimeko ezikhokelela kwi-optic atrophy inokunyangeka.

Umbono ophulukene ne-optic nerve atrophy awunakubuyiselwa. Kubaluleke kakhulu ukukhusela elinye iliso.

Abantu abakule meko kufuneka bahlolwe rhoqo ngugqirha wamehlo anamava kwiimeko ezinxulumene nemithambo-luvo. Tshela ugqirha wakho kwangoko ngalo naluphi na utshintsho kumbono.

Uninzi lwezinto ezibangela i-optic nerve atrophy azinakuthintelwa.

Amanyathelo othintelo abandakanya:

• Abantu abadala abadala kufuneka babe nomboneleli wabo ngokulawula uxinzelelo lwegazi.
• Sebenzisa amanyathelo okhuseleko aqhelekileyo ukuthintela ukwenzakala ebusweni. Ukonzakala okukhulu ebusweni ziziphumo zeengozi zeemoto. Ukunxiba amabhanti ezihlalo kunokunceda ukuthintela ukwenzakala.
• Cwangcisa uvavanyo lwamehlo rhoqo ngonyaka ukujonga i-glaucoma.
• Ungaze usele utywala obenziwe ekhaya kunye neentlobo zotywala ezingenzelwe ukusela. I-Methanol, enokufumaneka kubutywala obenziwe ekhaya, inokubangela i-optic nerve atrophy emehlweni omabini.
