Ngaba ufuna ukwazi kakuhle ngempilo yamehlo akho? Masifunde ngovavanyo (lwe-OCT)!

Ngaba wakha wahlolwa amehlo? Xa uvavanywa, ugqirha wakho angakuxelela ukuba wenze uvavanyo olukhethekileyo. Olunye uvavanyo olukhethekileyo nolubaluleke kakhulu esiza kuthetha ngalo namhlanje lubizwa ngokuba yi-OCT. Ungakhathazeki, kulula kakhulu kwaye alunantlungu.

Yintoni le (OCT)?

Ngamafutshane, i-Optical Coherence Tomography (OCT) yindlela ekhethekileyo enokuthabatha imifanekiso yoko kungaphakathi kweliso lakho. Kufana ne-ultrasound scan ukujonga ngaphakathi emzimbeni wakho, kodwa le yenziwa elisweni lakho. Isebenzisa ukukhanya kwe-infrared, okungenabungozi elisweni kwaye okungabonakaliyo kuthi, ukuthatha imifanekiso yeengqimba ezingaphakathi kweliso lakho. Ingabona ngokucacileyo iindawo ezibaluleke kakhulu ngasemva kweliso, njenge -retina kunye ne -optic nerve . Kufana ne-eye scan yokwenyani. Ngale ndlela, oogqirha banokulinganisa ubunzulu beliso lakho, bahlole iindawo ezahlukeneyo, kwaye baxilonge kwaye banyange naziphi na iimeko zonyango.

Oku ngamanye amaxesha kubizwa ngokuba yi-"ocular coherence tomography", "ocular" ithetha ukuba inxulumene neliso. Kule mihla, ubuchwepheshe be-OCT abusetyenziswa kuphela emehlweni, kodwa nakwezinye izifo. Umzekelo, busetyenziswa kwizinto ezifana novavanyo lwemithambo yegazi (i-Angiography). Iingcali kwi-cardiology, neurology, kunye ne-oncology nazo ziye zaqaphela iingenelo zale ndlela.

Ndifanele ndilwenze nini olu vavanyo (lwe-OCT)?

Ugqirha wakho angacebisa uvavanyo lwe-OCT ngokusekelwe kwiimpawu zakho okanye into abayibonayo ngexesha lovavanyo lwamehlo. Umzekelo, ukuba utshintshile ekuboneni kwakho okanye ukuba ugqirha wakho ukrokrela ukuba kukho into engalunganga ngeliso lakho, banokujonga okwenzekayo.

Kwakhona, kukho iingxaki zamehlo ezinxulumene nobudala eziza nobudala, ngoko ke kwabo basengozini yokuzifumana, okanye abasengozini yezinye izifo zamehlo, ugqirha unokucebisa ukuba benze i-OCT scan kunye novavanyo lwabo lwamehlo rhoqo. Emva koko banokuthatha ezi scans ngamanye amaxesha baze bazithelekise ukuze babone ukuba kukho naluphi na utshintsho. Kufana nokugcina ingxelo yempilo yamehlo ethu.

Zeziphi iintlobo zezifo zamehlo ezinokunceda i-OCT ukuxilonga nokunyanga?

Iingcali zamehlo zisebenzisa olu vavanyo (OCT) ukuhlola i-retina kunye ne-optic nerve ngasemva kweliso lakho. Lunokunceda ekuchongeni iimeko ezahlukeneyo ezinokuchaphazela umbono wakho. Nazi imizekelo embalwa:

• I-Glaucoma: Isifo seGlaucoma:Kwimeko enjalo, uxinzelelo olungaphakathi kweliso lunokwanda kwaye lonakalise umthambo wokubona. (OCT) ingasetyenziselwa ukubona ubungakanani bomonakalo kunye nobukhulu bomaleko wefayibha yemithambo-luvo.
• Ukonakala kweMacular: Le yimeko eqhelekileyo eyenzeka njengoko sikhula. I-macula, inxalenye yeliso apho sibona khona ngokucacileyo, yonakele. I-OCT inokunceda ekumiseleni uhlobo, nokuba lomile okanye limanzi, kunye nobungakanani bomonakalo.
• I-Diabetes-related macular edema: Ingxaki enkulu enokwenzeka kubantu abanesifo seswekile. I-macula iyadumba ngenxa yokuqokelelana kolwelo. I-Optical coherence tomography (OCT) inokulinganisa ngokuchanekileyo ubungakanani bokudumba.
• I-Retinopathy enxulumene nesifo seswekile: Isifo seswekile singonakalisa imithambo yegazi kwi-retina kwaye sibangele ukuba kubekho imithambo yegazi emitsha. Lo monakalo kunye nokwakheka kolwelo kunokubonakala ngokucacileyo nge-(OCT).
• Umhlaza Wamehlo: Oku kunceda ekuchongeni ezinye iintlobo zomhlaza wamehlo nokubona ubungakanani bazo.
• I-Optic Atrophy: Le meko inokwenzeka ngenxa yomonakalo kwi-optic nerve ngenxa yezizathu ezahlukeneyo. I-Optical coherence tomography (OCT) inokubonisa ukuncitshiswa kwe-nerve fibers.
• Ukuqhekeka kweRetina kunye neenyembezi zeRetina: Oku kubaluleke kakhulu ukuchonga izinto ezifana neenyembezi kunye neenyembezi ezincinci ngaphambi kokuba i-retina iqhekeke.
• Ukususwa kweVitreous yangasemva: Oku kuqhelekile nakubantu abadala. Ngamanye amaxesha i-OCT scan inokunceda ukubona ukuba ayichaphazeli i-retina.
• I-Central Serous Retinopathy: Le yimeko apho ulwelo luqokelelana phantsi kwe-retina, nto leyo enokubangela ukubona okufipheleyo. Olu layer lolwelo lunokubonwa ngokucacileyo nge-(OCT).
• I-Cystoid Macular Edema: Ukwakheka kwama-cyst amancinci, azaliswe lulwelo kwi-macula. Oku kunokwenzeka ngezizathu ezahlukeneyo.
• I-Bull's Eye Maculopathy: Imeko ebangela umonakalo kwipateni ethile "yeliso" (iliso lenkunzi) kwi-macula. Oku kunokubangelwa ngamayeza athile.
• I-Retinoschisis: Ukwahlukana kweengqimba ze-retina enye kwenye.

Ngamanye amaxesha, oogqirha basebenzisa le (OCT) ukujonga umphambili weliso, njenge-cornea kunye ne-iris. Oku kunokunceda ekuchongeni iziphene ezingaphambili kweliso okanye kucetywe utyando lwamehlo.

Lusebenza njani olu vavanyo (lwe-OCT)?

Kulula kakhulu. Ngaba ukhe weva nge-ultrasound scan? Isebenzisa amaza esandi ukuthumela emzimbeni ize emva koko yenze umfanekiso njengoko ebuyela umva. I-OCT iyafana, kodwa endaweni yokusebenzisa amaza esandi, isebenzisa ukukhanya okubomvu okungabonakaliyo.Xa le mitha yokukhanya ibetha izicubu ezingaphakathi kweliso lakho ize ibuyele umva, yenza imifanekiso enamacala amathathu (3D). Oku kuthetha ukuba unokubona okungaphakathi kweliso lakho ngokulandelelana . Cinga ngako njengokusika ikeyiki.

Oku akulimazi amehlo nangayiphi na indlela. Akukho nto ingena emehlweni. Yindlela ekhuselekileyo kakhulu.

Kwenzeka ntoni ngexesha lovavanyo (lwe-OCT)?

Olu luvavanyo olukhawulezileyo kakhulu olunokwenziwa ngemizuzu embalwa nje. Lwenziwa ngqo eofisini kagqirha wakho. Akukho lungiselelo lukhethekileyo lufunekayo. Lungenziwa nasemva kovavanyo lwakho lwamehlo oluqhelekileyo.

Ngaphambi kovavanyo, unganikwa amaconsi amehlo ukuze uvule iliso lakho. Oku kuya kukunceda ubone ingaphakathi leliso lakho ngokucacileyo. Emva koko uya kucelwa ukuba uhlale phambi kweskena kwaye uphumze isilevu sakho kwinkxaso eqhotyoshelwe kuso. Uya kucelwa ukuba ujonge ngqo kwisibane esiluhlaza.

Iskena (i-OCT) siskena iliso elinye ngexesha. Uza kubona umgca obomvu ngexesha lokuskena. Awuyi kuva nto, kwaye akukho nto iya kubetha iliso lakho. Kuthatha umzuzu okanye emibini kuphela ukuskena iliso elinye. Kubalulekile ukugcina iliso lakho likwindawo enye ngaphandle kokushukumisa intloko yakho ngeli xesha. Le yindlela ekuphela kwayo yokufumana umfanekiso ocacileyo.

Ngaba kukho naziphi na iziphumo ebezingalindelekanga koku?

Hayi, uvavanyo (lwe-OCT) ngokwalo alunazo iingozi okanye iziphumo ebezingalindelekanga. Lukhuselekile ngokupheleleyo. Nangona kunjalo, njengoko benditshilo ngaphambili, ukuba usebenzisa amayeza okwandisa iliso (ukwanda komfundi), unokufumana ukungakhululeki okuncinci okwethutyana emva koko. Umzekelo:

• Iyalumkela ukukhanya: Oku kuthetha ukuba amehlo akho anokubonakala ngathi aluhlaza okwesibhakabhaka xa uphuma elangeni. Ukunxiba iiglasi zelanga kunokunceda ekunciphiseni oku.
• Umbono ofipheleyo: Oku kubonakala ngakumbi xa ujonge kufutshane.

Ezi ngxaki zihlala ziphela ngokupheleleyo kwiiyure ezimbalwa (malunga neeyure ezi-4-6). Abanye abantu banokuba nentloko ebuhlungu.

Ngoko ke, ukuba uvavanywa ngaloo mayeza, kungcono ukuba omnye umntu akuqhubele ekhaya, okanye uphephe ukuqhuba, kuba kuthatha ixesha ukuba umbono wakho ubuyele esiqhelweni.

Zithini iziphumo ezifumanekayo? Zisixelela ntoni?

Ingcali yakho yamehlo (OCT) iza kufunda ngononophelo imifanekiso ethathwe kwiskeni. Le mifanekiso ifana nemephu yangaphakathi kweliso lakho. Ukuba ukhe waskeniwa ngaphambili, baza kuthelekisa le mifanekiso mitsha nezo mifanekiso ukuze babone ukuba kukho utshintsho, ukuphucuka, okanye ukuqhubeka kwesi sifo. Baza kuthetha nawe ngokukhawuleza ukuze bakuchazele oku.

Ezi ziphumo zinokunceda ugqirha wakho ukuba afumanise ukuba unesifo esichaphazela i-retina okanye i-optic nerve yakho, kwaye ukuba kunjalo, ukuba sisasazeke kangakanani kwaye sinzulu kangakanani. Esebenzisa olu lwazi, ugqirha wakho uza kucwangcisa unyango lwakho olulandelayo. Banokucebisa ukuba uqalise amayeza, unyango lwe-laser, okanye uhlaselo lwamehlo.

Ndifanele ndimbone nini ugqirha wam?

Kubaluleke kakhulu ukuba uhlolwe amehlo akho rhoqo. Ndwendwela ugqirha wakho rhoqo (rhoqo kwiinyanga ezi-6, kanye ngonyaka, umzekelo). Kulapho ugqirha wakho anokujonga khona naluphi na utshintsho ekuboneni kwakho. Ukuba uneempawu ezingaqhelekanga okanye uqaphele naluphi na utshintsho ekuboneni kwakho, ngokuqinisekileyo kufuneka uxelele ugqirha wakho. Musa ukuyityeshela loo nto, nokuba yinto encinci.

Ukuba unezinye zeempawu ezingezantsi, ungoyiki kwaye ubone ugqirha ngoko nangoko:

• Intlungu yamehlo entsha okanye engapheliyo.
• Ukuba unengxaki yokubona ngokucacileyo, ukuba indlela imibala ebonakala ngayo itshintshile, okanye ukuba izinto zibonakala zingacacanga.
• Ukuba uhlala ubona izinto ezibonakala ngathi zii-floaters phambi kwamehlo akho, okanye ukuba ubona ukukhanya okukhanyayo.
• Ukuba ngequbuliso ulahlekelwa kukubona, okanye ukuba inxalenye yombono wakho ibonakala imnyama.

Ngoko ke, umyalezo wokugqibela oza kugoduka nawo:

Ngamafutshane, olu vavanyo (OCT) luvavanyo olukhawulezayo kakhulu, olulula, olungenantlungu, noluphucukileyo kakhulu. Luthatha imifanekiso ye-layer-by-layer, enobukhulu obuthathu (3D) yangaphakathi kweliso lakho, ingakumbi iindawo ezibuthathaka ezingasemva kweliso, ezifana ne-retina kunye ne-optic nerve, kwaye ikuvumela ukuba uzibone kakuhle njenge-millimeter yewaka.

Oku kuvumela oogqirha ukuba bathathe imilinganiselo ngaphakathi kweliso, babone umonakalo kwi-optic nerve, baze babone iimeko ezinokuchaphazela umbono wakho kwasekuqaleni baze bacebe unyango. Ngoko ke, ukuba ugqirha ucela ukuba wenze olu vavanyo, akukho sizathu sokoyika. Inokuba linyathelo elibaluleke kakhulu kwimpilo yamehlo akho nasekugcineni umbono wakho oxabisekileyo.
