I-Optic Nerve Injury-03

Ukufumana kwakhona uMbono nge-Stem Cell Ngasemva kweLiso lokutofa kwi-Optic Nerve Injury

Ukulimala kwe-nerve ye-Optic kudala kudala umngeni kwinkalo yezonyango, kodwa ngenkqubela eqhubekayo yonyango lwe-stem cell, izigulane ezininzi zifumana ithemba elihlaziyiweyo. Namhlanje, sabelana ngemeko ekhuthazayo yesigulana, uNksk. Wang, owaphinda wafumana umbono ngenaliti ye-stem cell yangasemva.

UNksk. Wang, oneminyaka engama-42 ubudala, ungumfundisi-ntsapho. Kwiminyaka emibini edlulileyo, wonzakala kanobom ebuchotsheni nto leyo eyakhokelela kumonakalo kwimithambo-luvo yakhe yasekunene, yabangela ukwehla ngokukhawuleza kombono kunye nokulahlekelwa ngumbono ngokupheleleyo kwiliso lakhe lasekunene. Ukulahlekelwa ngumbono ixesha elide akuzange kuchaphazele umsebenzi wakhe nobomi bemihla ngemihla kuphela kodwa kwamfaka kudandatheko olunzulu.

Emva kokuzama iindlela ezahlukeneyo zonyango lwesintu ngaphandle kwempumelelo, ugqirha owayeza kugqirha uNksk. Emva kokubonisana okunzulu kunye nokuqonda inkqubo yonyango, uNksk.

Ngaphambi kokuqhubeka nonyango, uNksk. Wang wafumana iimviwo ezibanzi, kubandakanywa iimvavanyo zombono, ukuhlolwa kwe-fundus, i-imaging ye-optic nerve, kunye novavanyo lwezempilo jikelele. Ezi mvavanyo zaqinisekisa ukuba imeko yakhe yomzimba ifanelekile kunyango lwe-stem cell kwaye ibonelele ngesiseko senzululwazi sokuphuhlisa isicwangciso sonyango lomntu.

Emva kokuba kuqinisekiswe ukuba uNksk. Ngaphantsi kwe-anesthesia yendawo, utyando lubandakanya ubuchule obuncinci bokujova iiseli ze-stem kwindawo engasemva yeso, kufutshane nendawo ye-optic nerve. Yonke le nkqubo yathatha malunga neyure, apho uNksk. Oogqirha bakhokele inaliti echanekileyo yeeseli ze-stem besebenzisa umfanekiso wexesha lokwenyani ukuqinisekisa ukuba bafikelele kwindawo ekujoliswe kuyo ngokuchanekileyo.

Emva kotyando, uNksk. Wang wayebekwe esweni kwigumbi lokuchacha kangangeeyure eziliqela. Oogqirha bayila isicwangciso esibanzi sokumnyamekela emva kotyando, kuquka ukusetyenziswa kwamayeza okubulala iintsholongwane namayeza okulwa nokudumba, ukuxilongwa kwamehlo ngokuthe rhoqo, nothotho lwemithambo yokubuyisela kwimeko yesiqhelo. Ekupheleni kweveki yokuqala emva kokuhlinzwa, uNksk. Wang waqala ukubona ukukhanya okuncinci kwiliso lakhe lasekunene, inkqubela encinci eyayivuyisa yena kunye nosapho lwakhe.

Kwiinyanga ezimbalwa ezalandelayo, uNksk. Umbono wakhe waphucuka ngokuthe ngcembe, eqhubela phambili ukusuka kumbono wokukhanya ekuqaleni ukuya kukwazi ukuqaphela izinto ezilula kwaye ekugqibeleni waqonda iinkcukacha kumgama othile. Kwiinyanga ezintandathu kamva, umbono kaNksk. Wabuyela kwiqonga, eqhubeka nomsebenzi wakhe owuthandayo kwimfundo.

Ityala likaNksk. Wang eliphumeleleyo libonisa amandla amakhulu enaliti ye-stem cell posterior eye enyangeni ukwenzakala kwemithambo ye-optic. Olu nyango lulutsha aluzisi kuphela ithemba elitsha kwizigulana ezinokulimala kwemithambo ye-optic kodwa lukwabonelela ngedatha ebalulekileyo yeklinikhi kuphando lwezonyango. Sikholelwa ukuba ngokuhambela phambili okuqhubekayo kubugcisa benzululwazi, abaguli abangakumbi abonzakele kwimithambo-luvo baza kuphinda babone ngolu nyango, bamkele ubuhle bobomi kwakhona.
