Ngaba wakha wahlolwa amehlo akho waza ugqirha wathi, "Masithathe umfanekiso wangaphakathi kweliso lakho"? Xa wayesitsho loo nto, mhlawumbi waziva usoyika kancinci, uzibuza, "Uthatha njani umfanekiso wangaphakathi kweliso lakho? Ngaba liza kuba buhlungu? Kutheni usenza loo nto?" Enyanisweni, oku akuyonto yokoyika. Namhlanje, siza kuthetha ngovavanyo olubaluleke kakhulu olubizwa ngokuba yi-retinal imaging, okanye i-retinal imaging .
Ngamafutshane, yintoni iRetinal Imaging?
Ukujonga nge-retinal, ngokufutshane, bubuchwepheshe obukhethekileyo obusetyenziswa ukufota imifanekiso yedijithali yangaphakathi, inxalenye engasemva yeliso lakho. Kufana nokufota ngekhamera, kodwa kuthatha imifanekiso yoko kungaphakathi kweliso lakho.
Ngoku khangela, iliso lethu lifana nekhamera encinci. I-membrane engasemva kwayo yileyo siyibiza ngokuba yi-retina . Ifana nefilimu eqengqelekayo kwiikhamera ezindala. Imifanekiso yezinto esizibonayo yenziwe kule retina. Le retina ikwanayo nendawo ekhethekileyo ebizwa ngokuba yi-macula esinceda sibone ngokucacileyo. Kwakhona, kukho nezinye iindawo ezininzi ezibalulekileyo ngaphakathi ngasemva kweli liso, njenge -optic nerve, ethwala ulwazi oluvela kwiliso ukuya engqondweni.
Ngoko ke, into eyenziwa luvavanyo lwe-retina kukuthatha umfanekiso ocacileyo we-retina, i-macula, kunye ne-optic nerve, nayo yonke into ephakathi. Ugqirha wakho wamehlo unokufunda okuninzi malunga nempilo yamehlo akho ngokujonga le mifanekiso.
Kutheni kwenziwa olu vavanyo?
Khawucinge ukuba uya kujongwa amehlo minyaka le. Emva koko ugqirha uthatha umfanekiso onje aze awugcine kwifayile yakho. Xa uya kunyaka olandelayo, uthatha omnye umfanekiso aze awuthelekise nowakudala. Emva koko, ukuba kukho utshintsho oluncinci ngaphakathi kweliso, lunokuchongwa ngaphambi kokuba lube yingxaki enkulu. Kwakhona, ukuba unyangelwa isifo samehlo, le mifanekiso inceda ekuboneni ukuba unyango luphumelele na kwaye imeko engaphakathi kweliso iyaphucuka na.
Zeziphi izifo ezinokuchongwa nge-retina imaging?
Olu luvavanyo oluluncedo kakhulu kuba lunokubona iingxaki ezininzi ezinzulu zamehlo ezinokonakalisa ukubona kwakho kwasekuqaleni. Ukuba lufunyenwe kwangethuba, kukho ithuba elikhulu lonyango nokusindisa ukubona kwakho.
Nazi ezinye zeengxaki eziphambili zempilo ezinokuchongwa ngolu vavanyo:
| Imeko | Ingcaciso elula |

Lwenziwa njani olu vavanyo? Ingaba lubuhlungu?
Lo ngumbuzo abantu abaninzi abanawo. Impendulo kukuba, ayibuhlungu konke konke . Ilula kakhulu, ayibuhlungu. Ayibuhlungu konke konke emehlweni akho.
Kukho iindlela ezimbini zokuthatha le mifanekiso.
1. Iifoto zeFundus ezinemibala:Le yeyona ndlela ixhaphakileyo. I-Fundus lelinye igama lomva weliso. Oku kuquka ukuthatha imifanekiso enemibala yangaphakathi kweliso lakho usebenzisa ikhamera ekhethekileyo. Xa imifanekiso ithathwa, kukhutshwa ukukhanya okuqaqambileyo, njengefleshi yekhamera. Iikhamera ezintsha zinokuthatha imifanekiso ecacileyo kakhulu, enesisombululo esiphezulu. Ezinye iikhamera zinokuthatha umbono obanzi wendawo enkulu yangaphakathi kweliso. Le ndlela ilungile ekujongeni umonakalo kwimithambo yegazi obangelwa sisifo seswekile.
2. I-Optical Coherence Tomography (OCT): Le yindlela ephucuke kancinci. Ifana nokuthatha umfanekiso wecandelo elingaphakathi kweliso. Ingahlulahlula iileya ezahlukeneyo ze-retina kwaye ilinganise ubukhulu bazo. Olu vavanyo lwe-OCT lunceda kakhulu ekuchongeni ngokuchanekileyo iimeko ezifana ne-macular edema kunye ne-macular degeneration ebangelwa sisifo seswekile.
Eyona nto ibalulekileyo kukuba kuzo zombini ezi ndlela, okufuneka ukwenze kukuhlala esitulweni, ubeke intloko yakho kumatshini, uze ujonge isibane esincinci njengoko sikuxelela. Akukho nto iza kukwenzakalisa amehlo akho. Ngoko ke akukho sizathu sokoyika.
Ngamanye amaxesha, ukuba ugqirha ufuna ukujonga ngokusondeleyo imithambo yegazi engaphakathi kweliso, angenza olunye uvavanyo olubizwa ngokuba yiFluorescein Angiography . Oku kuquka ukufaka idayi ekhethekileyo emthanjeni osengalweni yakho. Xa idayi ihamba negazi iye kwimithambo engaphakathi kweliso, kunokubonwa ngokucacileyo ukuba kukho na ukuvaleka okanye ukuvaleka kwezo mithambo yegazi.
