Namhlanje siza kuthetha ngalo mbandela ubalulekileyo kwezonyango obizwa ngokuba yi-sudden vision loss.
Yintoni i-Sudden View Loss?
Ngamafutshane, ukulahleka kombono ngequbuliso yimeko engxamisekileyo yezonyango efuna unyango olukhawulezileyo. Oku kuthetha ukuba ngequbuliso ulahlekelwa kukubona ngokucacileyo, mhlawumbi kwimizuzwana, imizuzu, okanye kwaneentsuku.
