Reka twige ku bijyanye na OCT scan (Optical Coherence Tomography) ireba imbere mu jisho ryawe.

Ese wigeze wibaza uburyo umuganga ashobora kubona imitsi mito n'uduce tw'ijisho ryawe? Ni nko gukata ijisho ryawe ugafata amashusho meza, ariko nta bubabare. Ubu buryo butangaje bwitwa OCT scan. Muganga wawe w'amaso ashobora kuba yarabikubwiye, cyangwa se ukaba warigeze kumva izina mbere. Reka turebe icyo ari cyo n'impamvu ari ingenzi cyane.

Mu magambo make, gupima OCT ni iki?

Tomography y’ubufatanye bw’amaso, cyangwa nkuko twese tubizi, OCT scan , ni uburyo bwihariye bushobora gufata amashusho asobanutse neza y’ibice biri mu jisho, butinjije mu jisho mu buryo ubwo aribwo bwose (butari ubwandu).

Urugero rwiza rwo gusobanukirwa ibi ni scan ya ultrasound. Urabizi, scan ya ultrasound ikoreshwa mu kureba umwana uri mu nda, cyangwa kureba ingingo ziri mu mubiri. Ikibaho ni uko imiraba y'amajwi yoherezwa mu mubiri kandi uburyo igaragara inyuma igapimwa kugira ngo hakorwe ishusho. Ibyo ni nabyo bibaho muri OCT, ariko aho gukoresha imiraba y'amajwi, imiraba y'urumuri (urumuri rwa infrared) ikoreshwa. Iyi miraba y'urumuri ijya mu maso yacu ikagaragara inyuma na retina iri inyuma y'ijisho. Umucyo winjiye urapimwa maze mudasobwa igakora ishusho isobanutse neza, y'urwego ku rundi, ifite imiterere itatu (3D) ishobora kurebwa.

Ubu buryo butuma abaganga b'amaso bapima ubunini bw'ibice by'ingenzi by'ijisho ryawe no kumenya ibyangiritse, kubyimba, cyangwa impinduka muri byo neza cyane. Mbere, nta buryo bwo kubona ibintu nk'ibi neza. Ariko ikoranabuhanga rya OCT ryahinduye imikorere y'amaso.

Ibi ntibigarukira ku maso gusa. Ubu buryo bw'ikoranabuhanga buri gukoreshwa mu nzego nka cardiology, neurology, na oncology mu gusuzuma ibintu nk'imitsi y'amaraso.

Ni ryari ugomba gukora ikizamini cya OCT?

Umuganga w'amaso ashobora kukugira inama yo gupima OCT niba afite impungenge mu gihe cyo gupima amaso bisanzwe, cyangwa niba akeka ko hari ikibazo cy'uburwayi uterwa n'ibimenyetso byawe.

Tekereza ibi. Ufite imyaka irenga 50 kandi urwaye diyabete. Iyo ugiye kwisuzumisha amaso bisanzwe, muganga aravuga ati: "Bisa nkaho umuvuduko w'amaso yawe uri hejuru gato, kandi diyabete yawe ishobora kuba irimo kugira ingaruka ku mitsi yawe y'amaso. Reka dukore OCT kugira ngo turebe ibirimo kuba imbere."

Nanone, abantu bafite indwara zimwe na zimwe bashobora gukomeza kugira ibimenyetso, nubwo badafite.Gupima OCT bikoreshwa mu kugenzura impinduka mu jisho. Urugero, umuntu urwaye glaucoma ashobora gupimwa OCT inshuro imwe mu mwaka kugira ngo barebe niba ibyangiritse ku mitsi y'amaso byiyongereye cyangwa ko byakomeje kuba uko byari bimeze ugereranije n'ibyakozwe mbere. Ibi bishobora gufasha gupima intsinzi y'ubuvuzi no guhindura uburyo bwo kuvura bibaye ngombwa.

Ni izihe ndwara z'amaso zishobora kugaragara no kuvurwa hakoreshejwe OCT?

Gupima OCT ni byo bikunze gukoreshwa mu gusuzuma inyuma y'ijisho, ni ukuvuga retina n'imitsi y'amaso. Ibi bishobora gufasha mu kumenya indwara nyinshi zikomeye zigira ingaruka ku buryo butaziguye ku buryo tubona. Ushobora kubisobanukirwa neza mu mbonerahamwe iri hepfo.

Si ibi gusa, hari n'igihe ikoranabuhanga rya OCT rishobora gukoreshwa mu gusuzuma ibice by'imbere by'ijisho mbere yo kubagwa.

Iki kizamini gikorwa gite? Ese biragoye nkuko ubyibwira?

Oya rwose! Gupima OCT ni uburyo bworoshye kandi butababaza bushobora gukorwa mu minota mike . Ntabwo bisaba gutegura cyangwa imirire yihariye. Bishobora no gukorwa nyuma yo gupimwa amaso yawe buri gihe.

Dore uko bigenda intambwe ku yindi:

1. Kwagura: Hari igihe, kugira ngo ubone amashusho meza y’imbere mu jisho ryawe, muganga wawe azagushyira ibitonyanga mu jisho ryawe kugira ngo yagure imboni. Ibi si ngombwa buri gihe.

2. Kwicara imbere y'imashini: Hanyuma uzicara ku ntebe imbere ya scanner ya OCT. Agahanga kawe n'agahanga kawe bizashyirwa ku gikoresho gifatanye n'imashini. Ibi bizagufasha kugumana umutwe uhagaze kandi ntugire icyo uhindura.

3. Kureba ahantu hamwe: Hanyuma, uzasabwa kureba urumuri ruto rw'icyatsi kibisi ruri muri mashini udahumbya.

4. Gusuzuma: Mu gihe utegereje, imashini izasuzuma rimwe mu jisho ryawe. Ushobora kubona umurongo utukura uzenguruka. Nta kintu na kimwe kizagukubita ku jisho ryawe, kandi ntuzumva ububabare. Gusuzuma ijisho rimwe bizatwara igihe gito, nk'umunota umwe cyangwa ibiri. Icy'ingenzi ni uguhagarara ucecetse uko bishoboka kose muri iki gihe.

Iyo ijisho rimwe rimaze kurangira, irindi jisho risuzumwa muri ubwo buryo. Nguko uko byagenda kose! Igikorwa cyose ni vuba cyane.

Ese hari ingaruka mbi zishobora guterwa n'ikizamini cya OCT?

Iki ni cyo kintu cyiza kurusha ibindi. Nta ngaruka cyangwa ingaruka mbi bishobora kubaho ku isuzuma ryakozwe hifashishijwe OCT scanner. Ni umutekano 100%.

Ariko, nk'uko twabiganiriyeho mbere, niba ukoresheje ibitonyanga by'amaso kugira ngo wongere ijisho ryawe ry'umukara mbere yo gupimwa, bishobora gutera ububabare bw'igihe gito.

• Kubona nabi mu gihe cy'amasaha make.
• Gusobanukirwa urumuri rwinshi(Ni byiza kwambara indorerwamo z'izuba iyo ugiye hanze).
• Hari n'abantu bashobora kugira ikibazo cyo kubabara umutwe .

Ni iki twigira ku bisubizo byatanzwe?

Iyo scan irangiye, amashusho agaragara kuri ecran ya mudasobwa. Umuganga w'amaso azasuzuma amashusho witonze. Azashakisha ibintu nk'ubugari bw'ijisho, kubyimba, amazi yiyongera, cyangwa kwangirika kw'imitsi.

Niba warigeze gupimwa OCT mbere, muganga wawe azagereranya amashusho mashya n'aya kera. Ibi bizagufasha gusuzuma neza uburyo indwara yawe yagiye ihinduka uko igihe cyagiye gihita (ese yarushijeho kuba mbi, ese yarushijeho kuba nziza, cyangwa se yagumye uko yari imeze).

Nyuma yo gusesengura ibisubizo, muganga azagusobanurira uko ibintu bimeze. Hashingiwe ku bisubizo by'iki kizamini, hazafatwa ibyemezo ku bijyanye n'ubuvuzi bwawe bw'ejo hazaza ndetse niba ukeneye guhindura uburyo uvura ubu.

Ni ryari ngomba kubonana na muganga?

Ntukigere wibagirwa ibizamini by’amaso bisanzwe. Ibi bishobora kugufasha kubona ibibazo byinshi bikomeye hakiri kare. Byongeye kandi, niba ubonye kimwe mu bimenyetso biri hepfo, hita ubonana na muganga wawe.

• Ububabare bushya cyangwa buhoraho mu maso.
• Kugorwa no kubona neza cyangwa gutandukanya amabara .
• Ibyuma birebire cyangwa urumuri imbere y'amaso.
• Gutakaza ubushobozi bwo kureba cyangwa kugabanuka gukomeye mu byo umuntu abona.

Ntukirengagize ibi bintu. Hari igihe bishobora kuba ikimenyetso cya mbere cy'indwara ikomeye.
