Wake wahlolwa amehlo akho, udokotela wathi, "Ake sithathe isithombe sengaphakathi leso lakho"? Lapho esho lokho, cishe wazizwa wesaba kancane, uzibuza, "Usithatha kanjani isithombe sengaphakathi leso lakho? Ingabe kuzolimala? Kungani ukwenza lokho?" Empeleni, lokhu akumelwe ukwesabe. Namuhla, sizokhuluma ngokuhlolwa okubaluleke kakhulu okubizwa ngokuthi i-retinal imaging, noma i-retinal imaging .
Kalula nje, kuyini i-Retinal Imaging?
Ukuthwebula izithombe nge-retinal, kafushane nje, ubuchwepheshe obukhethekile obusetshenziswa ukuthatha izithombe zedijithali zangaphakathi, ingxenye yangemuva yeso lakho. Kufana nokuthatha isithombe ngekhamera, kodwa kuthatha izithombe zalokho okungaphakathi kweso lakho.
Bheka manje, iso lethu lifana nekhamera encane. Ulwelwesi olungemuva kwalo yilokho esikubiza ngokuthi i-retina . Kufana nokugoqwa kwefilimu kumakhamera amadala. Izithombe zezinto esizibonayo zakheka kule retina. Le retina inendawo ekhethekile ebizwa ngokuthi i-macula esisiza sibone ngokucacile. Futhi, kunezinye izingxenye eziningi ezibalulekile ngaphakathi kwaleli liso, njenge -optic nerve, ethwala ulwazi oluvela esweni luye ebuchosheni.
Ngakho-ke, lokho okwenziwa ukuhlolwa kwe-retinal imaging ukuthatha isithombe esicacile se-retina, i-macula, kanye ne-optic nerve, nakho konke okuphakathi. Udokotela wakho wamehlo angafunda okuningi ngempilo yamehlo akho ngokubuka lezi zithombe.
Kungani kwenziwa lokhu kuhlolwa?
Ake sithi uya kohlolwa amehlo njalo ngonyaka. Udokotela uthatha isithombe esinjengalesi asigcine efayeleni lakho. Uma uya ngonyaka olandelayo, uthatha esinye isithombe asiqhathanise neso esidala. Uma kukhona ushintsho oluncane ngaphakathi kweso, lungabonakala ngaphambi kokuba lube yinkinga enkulu. Futhi, uma welashelwa isifo samehlo, lezi zithombe ziyasiza ukubona ukuthi ukwelashwa kuyaphumelela yini nokuthi isimo ngaphakathi kweso siyathuthuka yini.
Yiziphi izifo ezingabonakala nge-retinal imaging?
Lokhu kuhlolwa okuwusizo kakhulu ngoba kungabona izimo eziningi ezimbi zamehlo ezingalimaza ukubona kwakho kusenesikhathi. Uma kutholakala kusenesikhathi, kunethuba elikhulu lokwelashwa nokusindisa ukubona kwakho.
Nazi ezinye zezimo zezokwelapha eziyinhloko ezingabonakala ngalolu vivinyo:
| Isimo | Incazelo elula |
|---|---|
| Ukulimala kwamehlo okubangelwa isifo sikashukela (i-Diabetes-related Retinopathy) | Abantu abanesifo sikashukela bangaba nomonakalo emithanjeni yegazi emehlweni abo. Lezi zithombe zibonisa ngokucacile lowo monakalo. |
| I-Macular Edema ehlobene nesifo sikashukela | Isifo sikashukela sibangela uketshezi ukuthi luqoqeke futhi luvuvuke ku-macula, ingxenye yeso. Lokhu kungabangela nokulahlekelwa umbono. |
| I-Glaucoma | Ukulimala kwe-optic nerve ngenxa yokucindezela okukhulu esweni. Lezi zithombe zingakusiza ukuthi uhlole kangcono isimo se-nerve. |
| Ukonakala kwe-Macular | Ukubona okufiphele lapho ubheka phambili ngenxa yomonakalo ku-macula njengoba sikhula. |
| Ukuhlukaniswa kwe-Retinal | Ukuqhekeka kwe-retinal ngemuva kweso. Lokhu kuyisimo esiphuthumayo. |
| Umdlavuza Wamehlo | Lokhu kusiza futhi ukuthola izimo zomdlavuza ezenzeka ngaphakathi kweso. |
Uma lezi zithombe zibonisa noma yiziphi izinkinga, udokotela wakho uzoncoma ukuthi yiluphi uhlobo lokwelashwa oludingayo.
Lokhu kuhlolwa kwenziwa kanjani? Ingabe kubuhlungu?
Lona umbuzo abantu abaningi abanawo. Impendulo ithi, akubuhlungu nhlobo . Kulula kakhulu, akubuhlungu. Akubuhlungu nhlobo emehlweni akho.
Kunezindlela ezimbili eziyinhloko zokuthatha lezi zithombe.
1. Izithombe ze-Fundus zombala:Lena yindlela evame kakhulu. I-Fundus elinye igama langemuva kweso. Lokhu kuhilela ukuthatha izithombe ezinemibala zangaphakathi kweso lakho usebenzisa ikhamera ekhethekile. Uma izithombe zithathwa, kukhishwa ukukhanya okukhulu, njenge-flash yekhamera. Amakhamera amasha angathatha izithombe ezicacile kakhulu, ezinesinqumo esiphezulu. Amanye amakhamera angathatha ngisho nombono obanzi wendawo enkulu yangaphakathi kweso. Le ndlela ilungele ukubheka umonakalo emithanjeni yegazi obangelwa isifo sikashukela.
2. I-Optical Coherence Tomography (OCT): Lena indlela ethuthuke kancane. Kufana nokuthatha isithombe sengxenye engaphakathi kweso. Ingahlukanisa izendlalelo ezahlukene ze-retina futhi ilinganise ukujiya kwazo. Lokhu kuhlolwa kwe-OCT kuyasiza kakhulu ekuxilongeni ngokunembile izimo ezifana ne-macular edema kanye ne-macular degeneration ebangelwa isifo sikashukela.
Into ebaluleke kakhulu ukuthi kuzo zombili lezi zindlela, okumele ukwenze nje ukuhlala esihlalweni, ubeke ikhanda lakho emshinini, bese ubheka isibani esincane njengoba sikutshela. Akukho lutho oluzolimaza amehlo akho. Ngakho-ke asikho isizathu sokwesaba.
Ngezinye izikhathi, uma udokotela efuna ukubhekisisa imithambo yegazi engaphakathi kweso, angenza futhi olunye uhlolo olubizwa ngokuthi i-Fluorescein Angiography . Lokhu kuhilela ukufaka idayi ekhethekile emthanjeni osengalweni yakho. Uma idayi ihamba negazi liye emithanjeni engaphakathi kweso, kungabonakala ngokucacile ukuthi kukhona yini ukuvaleka noma ukuvaleka kuleyo mithambo yegazi.
Kwenzekani ngaphambi nangesikhathi sokuhlolwa?
Kulungile, manje ake sibone ukuthi kufanele uzilungiselele kanjani lolu vivinyo nokuthi kuzokwenzekani phakathi nalo.
Ngaphambi kokuhlolwa
- Ngokuvamile, ngaphambi kwalokhu kuhlolwa, amehlo akho avuleka ngamaconsi amehlo. Kungani kwenziwa lokhu? Impumputhe ifana nefasitela lekhamera ukuze ibuke ngaphakathi kweso lakho. Uma ivuleka, ivumela izithombe ezicacile zangaphakathi kweso lakho.
- Okubalulekile: Uma umfundi wakho evuleke kanje, umbono wakho uzoba lufifi kancane amahora ambalwa. Namehlo akho azoba luhlaza okwesibhakabhaka uma uphuma ngaphandle. Ngakho-ke, ungashayeli ngosuku lokuhlolwa kwakho. Kungcono ukuba othile akushayele.
Ngesikhathi sokuhlolwa
Lonke lolu hlelo luthatha imizuzu emi-5 kuya kweyi-10. Lushesha kakhulu.
1. Uzohlaliswa esihlalweni phambi komshini wokuhlola.
2. Uzocelwa ukuthi ubeke isilevu sakho nebunzi lakho ezindaweni ezibekiwe. Lokhu kwenzelwa ukugcina ikhanda lakho lizinzile ngaphandle kokunyakaza.
3. Udokotela noma uchwepheshe ulungisa ikhamera neso lakho bese eqala ukuthatha izithombe.
4. Uzocelwa ukuthi ubheke ukukhanya okuncane okuluhlaza. Ukukhanya kukhanya kancane, ngakho-ke ungase uzizwe ungakhululekile, kodwa kuzohlala imizuzwana embalwa kuphela.
5. Uma usuqedile ukuthatha izithombe ngeso elilodwa, thatha izithombe ngeso elinye.
6. Uma umsebenzi usuqediwe, uzocelwa ukuba uvuke esihlalweni sakho. Yilokho kuphela!
Uma une-Fluorescein Angiography test, kungathatha cishe imizuzu engama-30.
Kwenzekani ngemva kokuhlolwa? Ingabe zikhona izingozi?
Ngemva kokuhlolwa
Njengoba sixoxile ngaphambili, umbono wakho uzoba lufifi amahora ambalwa ngenxa yokukhula komfundi wakho. Ngakho-ke:
- Ungashayeli.
- Yeka ukwenza izinto ezikhathaza amehlo akho, njengokufunda izincwadi, ukubuka ifoni yakho, noma ukubuka ikhompyutha.
- Uma uphuma, qiniseka ukuthi ugqoka izibuko zelanga. Lokhu kuzonciphisa amathuba okuba amehlo akho abe luhlaza okwesibhakabhaka.
Ingozi
Azikho izingozi ezaziwayo ngokuhlolwa kwe-retinal imaging ejwayelekile (i-fundus photography kanye ne-OCT). Ziphephile ngokuphelele ngoba zithatha isithombe ngekhamera kuphela.
Kodwa-ke, uma une-Fluorescein Angiography test (ukufaka idayi engalweni yakho), kungase kube nemiphumela emibi emincane kakhulu. Kodwa lokhu akuyona into okufanele ukhathazeke ngayo.
- Isikhumba singase siphenduke siphuzi kancane okwesikhashana.
- Umchamo ungaba phuzi noma ube nombala ophuzi (lokhu kuzonyamalala ngokuphelele zingakapheli amahora angama-24).
- Akuvamile kakhulu, abanye abantu bangase babe nokuqubuka kwesikhumba kanye nokulunywa ngenxa yokusabela kokungezwani komzimba.
- Isiyezi, umlomo owomile, ukunambitheka kwensimbi emlonyeni, isicanucanu, noma ukuhlanza kungenzeka kungavamile kakhulu.
Uma unokungabaza nganoma iyiphi yalezi zinto, buza udokotela wakho ngaphambi kokwenza ukuhlolwa.
Uthola kanjani imiphumela?
Lokhu kuhlolwa kukhiqiza izithombe zedijithali. Udokotela wakho uzohlola izithombe ngokucophelela. Angase akubonise izithombe futhi akuchazele ukuthi zikhombisa ini.
Lezi zithombe zigcinwa njengengxenye yerekhodi lakho lezokwelapha. Inzuzo yalokhu ukuthi uma usuphinda wenza lokhu kuhlolwa esikhathini esizayo, ungakuqhathanisa nezithombe ezindala bese ubona ngokunembile ukuthi amehlo akho ashintshe kanjani ngokuhamba kwesikhathi.
Ngakho-ke, ngesikhathi esizayo udokotela wakho ekucela ukuthi uthathe isithombe sengaphakathi leso lakho, ungesabi. Khumbula ukuthi kuwukuhlolwa okubaluleke kakhulu, okungenabuhlungu, futhi okusheshayo ukuvikela impilo yamehlo akho.
Umlayezo Wokuya Nawe Ekhaya
- Ukuthwebula Izithombe Ze-retinalKuwukuhlolwa okungenabuhlungu okuthatha izithombe zedijithali ze-retina, etholakala ngaphakathi kweso ngemuva.
- Lokhu kungasiza ekutholeni izifo eziningi ezinkulu kusenesikhathi, njengokulimala kwamehlo okubangelwa isifo sikashukela, i-glaucoma, kanye nokuwohloka kwe-macular.
- Akukho lutho oluzothintwa esweni lakho ngesikhathi sokuhlolwa. Ngakho-ke asikho isizathu sokwesaba.
- Ngenxa yokuthi umfundi uvame ukuvuleka ngaphambi kokuhlolwa, umbono ungase ufiphale amahora ambalwa. Ngakho-ke, gwema ukushayela ngosuku bese uletha othile ozokushayela ekhaya.
- Ukugcina izithombe zalolu vivinyo kurekhodi lakho lezokwelapha kuzokwenza kube lula ngodokotela wakho ukuqapha noma yiziphi izinguquko esweni lakho esikhathini esizayo.
- Uma unemibuzo mayelana nalolu vivinyo, ungangabazi ukubuza udokotela wakho.
