Ngaba wakha wazibuza ukuba ugqirha angayibona njani imithambo-luvo emincinci kunye neengqimba ezingaphakathi kweliso lakho? Kufana nokusika iliso lakho uvule uze uthathe imifanekiso ecacileyo, kodwa akukho buhlungu. Le teknoloji imangalisayo ibizwa ngokuba yi-OCT scan. Ugqirha wakho wamehlo usenokuba ukuxelele ngayo, okanye usenokuba ukhe wayiva igama ngaphambili. Makhe sijonge ukuba yintoni na kwaye kutheni ibaluleke kangaka.
Ngamafutshane, yintoni i-OCT scan?
I-Optical Coherence Tomography, okanye njengoko sonke sisazi, i -OCT scan , yindlela ekhethekileyo enokuthabatha imifanekiso ecacileyo yeendawo ezingaphakathi kweliso, ngaphandle kokungena elisweni nangayiphi na indlela (engangenisi gazi).
Umzekelo ongcono wokuqonda oku yi-ultrasound scan. Uyazi, ii-ultrasound scans zisetyenziselwa ukujonga usana olusesibelekweni, okanye ukujonga amalungu angaphakathi emzimbeni. Okwenzekayo apho kukuba amaza esandi athunyelwa emzimbeni kwaye indlela abonakaliswa ngayo ngasemva ilinganiswa ukwenza umfanekiso. Kwenzeka into efanayo kwi-OCT, kodwa endaweni yamaza esandi, kusetyenziswa amaza okukhanya (ukukhanya kwe-infrared) . Le mitha yokukhanya ingena emehlweni ethu kwaye ibonakaliswa ngasemva yi-retina ngasemva kweliso. Ukukhanya okungenayo kuyalinganiswa kwaye ikhompyutha idala umfanekiso ocacileyo kakhulu, omaleko ngamaleko, onemilinganiselo emithathu (3D) onokubonwa.
Oku kufana nokusika ikhekhe ngaphandle kokuyisika, kodwa ubona ngokucacileyo zonke iileya zekhrimu kunye neeleya zesiponji ngaphakathi kuyo ngokwahlukeneyo.
Le teknoloji ivumela oogqirha bamehlo ukuba balinganise ubukhulu bezona ndawo zibalulekileyo zeliso lakho baze babone nawuphi na umonakalo, ukudumba, okanye utshintsho kuzo ngokuchanekileyo okukhulu. Ngaphambili, bekungekho ndlela yokubona izinto ezinje ngokucacileyo. Kodwa iteknoloji ye-OCT itshintshe kakhulu i-ophthalmology.
Oku akupheleli nje emehlweni. Le teknoloji ngoku isetyenziswa kwiinkalo ezifana ne-cardiology, neurology, kunye ne-oncology ukuhlola izinto ezifana nemithambo yegazi.
Ufanele wenze nini uvavanyo lwe-OCT?
Ingcali yakho yamehlo inokucebisa uvavanyo lwe-OCT ukuba inenkxalabo ngexesha lovavanyo lwamehlo oluqhelekileyo, okanye ukuba irhanela imeko yempilo ngokusekelwe kwiimpawu zakho.
Khawucinge nje ngoku. Uneminyaka engaphezu kwama-50 ubudala kwaye unesifo seswekile. Xa usiya kuvavanyo lwamehlo oluqhelekileyo, ugqirha uthi, "Kubonakala ngathi uxinzelelo lwamehlo akho luphezulu kancinci, kwaye isifo sakho seswekile sisenokuba sichaphazela imithambo-luvo yakho yamehlo. Masenze i-OCT ukuze sibone ukuba kwenzeka ntoni ngaphakathi."
Kwakhona, abantu abaneengxaki ezithile zempilo banokuqhubeka benazo iimpawu, nokuba abanazo.Ii-OCT scan zisetyenziselwa ukujonga utshintsho olusesweni. Umzekelo, umntu one-glaucoma unokwenziwa i-OCT scan malunga kanye ngonyaka ukuze kubonwe ukuba umonakalo kwi-optic nerve unyukile okanye awukatshintshi na xa kuthelekiswa nee-scan zangaphambili. Oku kunokunceda ukulinganisa impumelelo yonyango kunye nokulungisa unyango ukuba kuyimfuneko.
Zeziphi izifo zamehlo ezinokufunyaniswa kwaye zilawulwe nge-OCT?
I-OCT scan isetyenziswa kakhulu ukuhlola umva weliso, oko kukuthi i-retina kunye ne-optic nerve. Oku kunokunceda ekufumaneni izifo ezininzi ezinzulu ezichaphazela ngqo umbono wethu. Ungafumana umbono olungileyo ngale nto kwitheyibhile engasezantsi.
| Imeko | Kalula nje... |
|---|---|
| I-Glaucoma | Ukonakala kwe-optic nerve, i-optic nerve ephambili ethwala umbono ukuya ebuchosheni, ngenxa yoxinzelelo oluphezulu elisweni. I-OCT ilinganisa ubukhulu bale maleko ye-nerve fiber ukuze ihlole umonakalo. |
| Ukuwohloka kwe-macular okunxulumene nobudala | Ukonakala kwenxalenye esembindini ye-retina (macula), enika umbono obukhali. I-OCT ibonisa ngokucacileyo utshintsho olwenzeka apha. |
| Ukonakala kwamehlo ngenxa yesifo seswekile (i-Diabetic Retinopathy) | Isifo seswekile singonakalisa imithambo yegazi kwi-retina, nto leyo ebangela ukuba ulwelo luvuze okanye ludumbe (i-macular edema). I-OCT inokulinganisa ngokuchanekileyo oku kudumba. |
| Ukuqhekeka kweRetinal okanye iinyembezi | Inwebu ebukhali engasemva kweliso enika umbono yahlukile kwiileya ezingaphantsi. Le yimeko engxamisekileyo. |
| Ukudumba kwesokhethi yeliso (i-Cystoid Macular Edema) | Umbono ofipheleyo ngenxa yokwakheka kwamaqhuqhuva amancinci azaliswe lulwelo kwi-macula, embindini wombono. |
| Ukuwohloka Kwamehlo | Ukonakala kwe-optic nerve kunye nokoma kwayo kancinci kancinci. |
Akupheleli apho, kukwakho neemeko apho ubuchwepheshe be-OCT bungasetyenziswa ukuhlola iindawo ezingaphambili zeliso ngaphambi kotyando lweliso.
Lwenziwa njani olu vavanyo? Ingaba lunzima njengoko ucinga?
Akunjalo konke konke! I-OCT scan yinkqubo elula, engenabuhlungu enokwenziwa ngemizuzu embalwa . Ayifuni naluphi na ulungiselelo olukhethekileyo okanye imiqathango yokutya. Ingenziwa nasemva kovavanyo lwakho lwamehlo oluqhelekileyo.
Nantsi into eyenzekayo inyathelo ngenyathelo:
1. Ukwandisa: Ngamanye amaxesha, ukuze ufumane imifanekiso ecacileyo yangaphakathi kweliso lakho, ugqirha wakho uza kubeka amaconsi emehlweni akho ukuze andise umbungu. Oku akusoloko kuyimfuneko.
2. Ukuhlala phambi komatshini: Emva koko uza kuhlala kwisitulo esiphambi kweskena se-OCT. Isilevu sakho kunye nebunzi ziya kubekwa kwisiseko esiqhotyoshelwe kumatshini. Oku kuya kukunceda ugcine intloko yakho ingashukumi.
3. Ukujonga kwindawo enye: Okulandelayo, uza kucelwa ukuba ujonge isibane esiluhlaza esincinci ngaphakathi kumatshini ngaphandle kokuqhwanyaza.
4. Ukuskena: Ngelixa ulindile, umatshini uza kuskena elinye lamehlo akho. Ungabona umgca obomvu uhambahamba. Akukho nto iya kukuchukumisa iliso, kwaye awuyi kuva ntlungu. Ukuskena iliso elinye kuya kuthatha ixesha elifutshane, malunga nomzuzu okanye emibini. Eyona nto ibalulekileyo kukuhlala uzolile kangangoko ngeli xesha.
Xa elinye iliso ligqibile, elinye iliso liyaskenwa ngendlela efanayo. Yiyo leyo! Yonke le nkqubo ikhawuleza kakhulu.
Ngaba kukho naziphi na iziphumo ebezingalindelekanga ezivela kuvavanyo lwe-OCT?
Le yeyona nto ilungileyo. Akukho zingozi okanye iziphumo ebezingalindelekanga kuvavanyo olwenziwe nge-OCT scanner. Ikhuselekile ngokupheleleyo.
Nangona kunjalo, njengoko besitshilo ngaphambili, ukuba usebenzisa amaconsi amehlo ukwandisa iliso lakho elimnyama ngaphambi kovavanyo, kunokubangela ukungakhululeki okwethutyana.
- Umbono ofipheleyo kangangeeyure ezimbalwa.
- Uvakalelo ekukhanyeni okukhanyayo(Licebo elihle ukunxiba iiglasi zelanga xa uphuma phandle).
- Abanye abantu banokuba nentloko ebuhlungu .
Eyona nto ibalulekileyo kukuba ukuba uyazi ukuba uza kufakwa amaconsi emehlweni akho, ungaqhubi ngaloo mini. Kuyingozi ukuqhuba ude ubone kwakhona. Ngoko ke, bubulumko ukuza nomnye umntu okanye usebenzise olunye uhlobo lokuhamba.
Sifunda ntoni kwiziphumo?
Nje ukuba iskeni igqityiwe, imifanekiso iboniswa kwiscreen sekhompyutha. Ugqirha wakho wamehlo uza kuyihlola ngononophelo imifanekiso. Uza kukhangela izinto ezinje ngobukhulu beeleya zeliso, nakuphi na ukudumba, ukwakheka kolwelo, okanye umonakalo kwimicu yemithambo-luvo.
Ukuba ukhe wavavanywa i-OCT ngaphambili, ugqirha wakho uza kuthelekisa imifanekiso emitsha neyakudala. Oku kuya kukunceda uvavanye ngokuchanekileyo indlela imeko yakho etshintshe ngayo ngokuhamba kwexesha (ingaba iye yaba mandundu, ingaba iye yaba ngcono, okanye ihlale injalo).
Emva kokuhlalutya iziphumo, ugqirha uza kukuchazela imeko. Ngokusekelwe kwiziphumo zolu vavanyo, kuza kwenziwa izigqibo malunga nonyango lwakho lwexesha elizayo kunye nokuba kufuneka utshintshe unyango lwakho lwangoku na.
Ndifanele ndibonane nogqirha nini?
Ungaze ululibale uvavanyo lwakho lwamehlo oluqhelekileyo. Oku kunokukunceda ufumane iingxaki ezininzi ezinzulu kwangethuba. Ukongeza, ukuba ufumana naziphi na iimpawu ezingezantsi, bonana nogqirha wakho ngoko nangoko.
- Intlungu yamehlo entsha okanye engapheliyo.
- Ubunzima bokubona ngokucacileyo okanye ukwahlula imibala .
- Iingqayi zamehlo okanye ukukhanya okukhanyayo phambi kwamehlo.
- Ukulahlekelwa ngumbono ngequbuliso okanye ukuncipha okukhulu kombono.
Musa ukuzityeshela ezi zinto. Ngamanye amaxesha zinokuba ziimpawu zokuqala zesifo esinzulu.
Umyalezo Wokuya Ekhaya
- I-OCT scan luvavanyo olukhuselekileyo nolungenabuhlungu oluthatha umfanekiso weengqimba ezingaphakathi kweliso lakho.
- Oku kuvumela ukufunyanwa kwangethuba kunye nonyango lwezifo ezininzi, ezifana ne-glaucoma kunye ne-diabetes retinopathy.
- Nangona kungekho ziphumo zimbi ezivela kwiskeni, amathontsi eliso asetyenziselwa ukwandisa iliso anokubangela ukubona okufipheleyo kangangeeyure ezimbalwa. Ngoko ke, kuphephe ukuqhuba imoto.
- Ukuba ubona naluphi na utshintsho olukhawulezileyo ekuboneni kwakho, kwiintlungu, okanye nantoni na engaqhelekanga, funa ingcebiso yezonyango ngokukhawuleza. Ungaze uyityeshele.
