Ukulimala kweMithambo yoMbono-03

Ukuphinda Ubone Ngokusebenzisa Inaliti Yeliso Lasemva Kwe-Stem Cell Ukulimala Kwe-Optic Nerve

Ukulimala kwemithambo-luvo yamehlo kudala kube ngumngeni kwicandelo lezonyango, kodwa ngokuqhubeka nonyango lwee-stem cell, izigulane ezininzi zifumana ithemba elitsha. Namhlanje, sabelana ngetyala elikhuthazayo lesigulana, uNksk. Wang, owaphinda wabona ngokujova i-stem cell esweni.

UNksk. Wang, oneminyaka engama-42 ubudala, ungutitshala. Kwiminyaka emibini eyadlulayo, wenzakele kakhulu engqondweni nto leyo eyabangela umonakalo kwimithambo-luvo yakhe yasekunene, nto leyo eyabangela ukwehla ngokukhawuleza kombono kunye nokulahlekelwa phantse ngokupheleleyo kombono kwiliso lakhe lasekunene. Ukulahlekelwa ngumbono ixesha elide akuzange kuchaphazele umsebenzi wakhe nobomi bakhe bemihla ngemihla kuphela kodwa kwamenza wadandatheka kakhulu.

Emva kokuzama iindlela ezahlukeneyo zonyango lwesintu kodwa akaphumelela, ugqirha kaNksk. Wang wamcebisa ukuba azame unyango olutsha—utyando lwe-stem cell posterior eye injection. Emva kokubonisana ngokucokisekileyo nokuqonda inkqubo yonyango, uNksk. Wang wagqiba ekubeni angene kolu nyango lutsha, enethemba lokubuyisela umbono wakhe.

Ngaphambi kokuba aqhubeke nonyango, uNksk. Wang wenze uvavanyo olupheleleyo, oluquka uvavanyo lombono, uvavanyo lwe-fundus, i-optic nerve imaging, kunye novavanyo lwempilo iyonke. Olu vavanyo luqinisekisile ukuba imeko yakhe yomzimba ifanelekile kunyango lweeseli ze-stem kwaye lubonelela ngesiseko sesayensi sokuphuhlisa isicwangciso sonyango esilungiselelwe wena.

Emva kokuba kuqinisekiswe ukuba uNksk. Wang wayefanelekile utyando, iqela lezonyango laqulunqa isicwangciso esineenkcukacha zotyando. Phantsi kwe-anesthesia yendawo, olu tyando lwalubandakanya iindlela ezingaphantsi kakhulu zokufaka ii-stem cells kwinxalenye engasemva yeliso, kufutshane nendawo ekuyo i-optic nerve. Lonke olu tyando lwathatha malunga neyure, apho uNksk. Wang wafumana ukungakhululeki okuncinci. Oogqirha bakhokela ukujova ngokuchanekileyo ii-stem cells besebenzisa imifanekiso yexesha langempela ukuqinisekisa ukuba zifikelela kwindawo ekujoliswe kuyo ngokuchanekileyo.

Emva kotyando, uNksk. Wang wajongwa kwigumbi lokuchacha kangangeeyure ezininzi. Oogqirha baceba isicwangciso esibanzi sonyango emva kotyando, kuquka ukusetyenziswa kwamayeza okubulala iintsholongwane kunye namayeza okulwa nokuvuvukala, ukuvavanywa rhoqo kwamehlo, kunye nothotho lwemisebenzi yokubuyisela impilo. Ekupheleni kweveki yokuqala emva kotyando, uNksk. Wang waqala ukubona ukukhanya okuncinci kwiliso lakhe lasekunene, inkqubela encinci eyamvuyisa yena nosapho lwakhe.

Kwiinyanga ezimbalwa ezalandelayo, uNksk. Wang wayesiya rhoqo kwizikolo zokulandelela esibhedlele kwaye wathatha inxaxheba kuqeqesho lokubuyisela kwimeko yesiqhelo. Umbono wakhe waphucuka kancinci kancinci, esiya ekubeni nombono wokukhanya ekuqaleni ukuya ekubeni akwazi ukubona imida yezinto ezilula aze ekugqibeleni aqonde iinkcukacha ngaphakathi kumgama othile. Kwiinyanga ezintandathu kamva, umbono kaNksk. Wang kwiliso lakhe lasekunene wawuphucuke waya kwi-0.3, nto leyo eyabangela ukuba ubomi bakhe buphucuke kakhulu. Wabuyela eqongeni, eqhubeka nomsebenzi wakhe amthandayo kwezemfundo.

Ityala eliphumeleleyo likaNksk. Wang libonisa amandla amakhulu okufakwa kwe-stem cell posterior eye ekunyangeni ukwenzakala kwe-optic nerve. Olu nyango lutsha aluzisi nje kuphela ithemba elitsha kwizigulane ezenzakeleyo kwi-optic nerve kodwa lukwabonelela ngeenkcukacha ezibalulekileyo zeklinikhi zophando lwezonyango. Sikholelwa ukuba ngokuqhubeka kwenkqubela phambili kubuchwepheshe besayensi, izigulane ezininzi ezenzakeleyo kwi-optic nerve ziya kuphinda zibone ngolu nyango, zamkele ubuhle bobomi kwakhona.
