Ngasemva kwamehlo ethu, kukho inxalenye efana nesikrini ebuthathaka kakhulu. Le yinto esiyibiza ngokuba yi-retina . Ifana nefilimu ekwikhamera. Ukukhanya okuvela kwizinto esizibonayo kuguqulwa kube ziimpawu zombane ezinokuqondwa yingqondo. Emva koko, ezo zimpawu zihamba nge-optic nerve ziye engqondweni, apho sibona khona umfanekiso.
Le 'retina' ikwaqulathe indawo encinci ebaluleke kakhulu ebizwa ngokuba yi-macula . Le 'macula' yiyo esinceda sibone iinkcukacha ezincinci, njengokufunda oonobumba abancinci ngokucacileyo nokubona imbonakalo yobuso engabonakaliyo. Ukuze le nxalenye isebenze kakuhle, kufuneka ifumane igazi elifanelekileyo kwimithambo yegazi ekwi 'retina'.
Ngoku kulapho ingxaki iqala khona. Ukuba isifo sakho seswekile asilawulwa kakuhle, ngokuhamba kwexesha le mithambo yegazi mincinci iyonakala. Ingaqala ukuvuza igazi okanye ulwelo. Le meko siyibiza ngokuba yiDiabetic Retinopathy . Lo ngumonakalo omkhulu emehlweni obangelwa sisifo seswekile.
Ayipheleli apho, abantu abanesifo seswekile basengozini enkulu yokufumana ezinye izifo ezininzi:
- I-Glaucoma: Le yimeko apho uxinzelelo ngaphakathi kweliso lunyuka. Olu xinzelelo lunyukayo lunokonakalisa umthambo we-optic kwaye lukhokelele ekulahlekelweni kokubona kancinci kancinci. Umngcipheko uyanda njengoko umntu enesifo seswekile ixesha elide.
- IiCataracts: Abantu abanesifo seswekile basengozini enkulu yokuba ne-cataracts, ukufiphala kwelensi yeliso, besebancinci kunabantu ngokubanzi.
