Ngoku kutshanje, bekukholelwa ukuba kwizilwanyana ijwabu leso eliqhawulayo (elibizwa ngokuba liyesithathu) lilungu eliyingozi elingenzi naliphi na umsebenzi. Kodwa uphando lwangoku kwintsimi ye-ophthalmology yezilwanyana (iinkonzo ngokukhethekileyo) ziye zabonisa ukuba ijwabu leso elimhlophe liyimfuneko yokuba kugcinwe ubuso kwimeko enempilo. Inkophelo, xa ixhamla ebusweni beso liso, isusa iinqununu zothuli kuwo, isasaza i-tardrop efanayo phezu kwayo yonke indawo kwaye ikhusela i-cornea kwi-trauma. Ngako oko, naluphi na ukuvuvukala kwangaphakathi (imiqathango efanayo - inkulungwane yesibhakabhaka, yesithathu) kwikati inokubangela iingxaki ezinzulu ngombono.
Unyango lwenkulungwane yesithathu kwiikati
Ukuba ikati inomlenze wesithathu (ichanekile ngakumbi ukuba kukho ukuvuvukala okanye ukulahleka okucacileyo), okokuqala, isizathu solu hlobo kufuneka sisungulwe. Kwaye izizathu zokuphambuka kokusebenza ngokuqhelekileyo kwekhulu lesithathu kwiikati zingafani kakhulu. Isizathu esivamekileyo sokusabalalisa kwesosididi esikhanyayo kukukho kwiso lokuvuselela (umzekelo, ukungena komzimba wangaphandle) okanye ukuphulwa kwe-cornea yelihlo. Ngokuphindaphindiweyo ukuvuvukala kwethambo lesithathu kwiikati kubonakala kwizifo zamehlo, umzekelo, ngokudibanisa . Ukuchaphazela imeko ye-eyelidi yangaphakathi kunye nesifo se-virtual etiology kunye neengxaki ekusebenzeni kwimihlathi yesisu. Kodwa, nokuba kunjalo, ukunyanga nayiphi na inguqu kwikhulu lesithathu kwiikati , kwaye nangona kunjalo ukuba isifo sihamba kunye nokulahleka kwesidlo, isifo sohudo, umkhuhlane, kufuneka uhambe kwiklinikhi yezilwanyana. Ugqirha wezilwanyana kuphela, xa uhlalutye zonke iimpawu, unokunikezela inkqubo yokwelashwa oluyimfuneko. Ngendlela, imbangela yokulahlekelwa kwekhulu leminyaka yesithathu, engafuneki ukungenelela kwezonyango, inokubakho ukuxhatshazwa kwezilwanyana (umzekelo, ngokuzama kwemizamo). Ngokuqhelekileyo, ukuba impilo yekati ngokubanzi ingabangeli ukuxhalaba, imeko yesikhumba sekhaya ngaphakathi kule meko iqhelekile ngaphandle kokungenelela kwezonyango.
