Ufuna ukwazi kahle impilo yamehlo akho? Ake sifunde ngokuhlolwa (kwe-OCT)!

Wake wahlolwa amehlo? Uma wenza kanjalo, udokotela wakho angase akutshele ukuthi wenze ukuhlolwa okukhethekile. Ukuhlolwa okukhethekile nokubaluleke kakhulu esizokhuluma ngakho namuhla kubizwa ngokuthi i-OCT. Ungakhathazeki, kulula kakhulu futhi akubuhlungu.

Kuyini lokhu (OCT)?

Kalula nje, i-Optical Coherence Tomography (OCT) iyindlela ekhethekile engathatha izithombe zalokho okungaphakathi kweso lakho. Kufana nokuskena kwe-ultrasound ukuze kubhekwe ngaphakathi emzimbeni wakho, kodwa lokhu kwenziwa esweni lakho. Kusebenzisa ukukhanya kwe-infrared, okungenangozi esweni futhi okungabonakali kithi, ukuthatha izithombe zezingqimba ezingaphakathi kweso lakho. Kungabona ngokucacile izingxenye ezibaluleke kakhulu ngemuva kweso, njenge -retina kanye ne-optic nerve . Kufana nokuskena kwangempela kweso. Ngale ndlela, odokotela bangalinganisa ukujula kweso lakho, bahlole izingxenye ezahlukene, futhi baxilonge futhi baphathe noma yiziphi izimo zezokwelapha.

Lokhu ngezinye izikhathi kubizwa ngokuthi "i-ocular coherence tomography", "i-ocular" okusho ukuthi kuhlobene neso. Namuhla, ubuchwepheshe be-OCT abusetshenziswa kuphela emehlweni, kodwa nakwezinye izifo. Isibonelo, busetshenziselwa izinto ezifana nokuhlolwa kwemithambo yegazi (i-Angiography). Ochwepheshe be-cardiology, i-neurology, kanye ne-oncology nabo baye baqaphela izinzuzo zale ndlela.

Kufanele ngilwenze nini lolu vivinyo (i-OCT)?

Udokotela wakho angase asikisele ukuhlolwa kwe-OCT ngokusekelwe ezimpawini zakho noma okuthile akubonayo ngesikhathi sokuhlolwa kwamehlo. Isibonelo, uma ubona ushintsho ekuboneni kwakho noma uma udokotela wakho esola ukuthi kukhona okungahambi kahle ngeso lakho, angabheka ukuthi kwenzekani.

Futhi, kunezinkinga zamehlo ezihlobene nokuguga ezihambisana nokuguga, ngakho kulabo abasengozini yokuzithola, noma abasengozini yezinye izifo zamehlo, udokotela angase atuse ukuthi benze i-OCT scan kanye nokuhlolwa kwamehlo kwabo okuvamile. Ngemuva kwalokho bangathatha lezi scan ngezikhathi ezithile futhi baziqhathanise ukuze babone ukuthi kukhona yini ushintsho. Kufana nokugcina irekhodi lempilo yamehlo ethu.

Yiziphi izinhlobo zezifo zamehlo i-OCT engasiza ekuxilongeni nasekuphatheni?

Odokotela bamehlo basebenzisa lokhu kuhlolwa (i-OCT) ukuhlola i-retina kanye ne-optic nerve ngemuva kweso lakho. Kungasiza ekuxilongeni izimo ezahlukahlukene ezingathinta umbono wakho. Nazi izibonelo ezimbalwa:

• I-Glaucoma:Kulesi simo, ingcindezi engaphakathi kweso inganda futhi yonakalise i-optic nerve. (OCT) ingasetshenziswa ukubona ubukhulu balo monakalo kanye nobukhulu bengqimba ye-nerve fiber.
• Ukonakala kwe-Macular: Lesi yisimo esivamile esenzeka njengoba sikhula. I-macula, ingxenye yeso lapho sibona khona ngokucacile, yonakele. I-OCT ingasiza ekunqumeni uhlobo, ukuthi lomile noma limanzi, kanye nobukhulu bomonakalo.
• I-Diabetes-related macular edema: Inkinga enkulu engenzeka kubantu abanesifo sikashukela. I-macula iyavuvukala ngenxa yokuqongelela koketshezi. I-Optical coherence tomography (OCT) ingalinganisa ngokunembile ubukhulu balokhu kuvuvukala.
• I-Retinopathy ehlobene nesifo sikashukela: Isifo sikashukela singalimaza imithambo yegazi ku-retina futhi sibangele ukwakheka kwemithambo yegazi emisha. Lo monakalo kanye nokuqongelela koketshezi kungabonakala ngokucacile nge-(OCT).
• Umdlavuza Wamehlo: Lokhu kusiza futhi ukuhlonza izinhlobo ezithile zomdlavuza wamehlo nokubona ubukhulu bawo.
• I-Optic Atrophy: Lesi simo singabangelwa ukulimala kwe-optic nerve ngenxa yezizathu ezahlukahlukene. I-Optical coherence tomography (OCT) ingabonisa ukuncipha kwezintambo ze-nerve.
• Ukuhlukaniswa Kwe-Retinal kanye Nezinyembezi Ze-Retinal: Lokhu kubaluleke kakhulu ukuhlonza izinto ezifana nokunyembeza kanye nokunyembeza okuncane ngaphambi kokuba i-retinal ihlukane.
• Ukususwa Kwama-Vitreous Angemuva: Lokhu kuvamile futhi ngokweminyaka. Ngezinye izikhathi i-OCT scan ingasiza ekuboneni ukuthi iyayithinta yini i-retina.
• I-Central Serous Retinopathy: Lesi yisimo lapho uketshezi luqoqana khona ngaphansi kwe-retina, okungabangela ukubona okufiphele. Lolu ngqimba loketshezi lungabonakala kahle nge-(OCT).
• I-Cystoid Macular Edema: Ukwakheka kwama-cyst amancane, agcwele uketshezi ku-macula. Lokhu kungenzeka ngezizathu ezahlukahlukene.
• I-Bull's Eye Maculopathy: Isimo esibangela umonakalo kuphethini ethize "ye-target" (ye-bull's eye) ku-macula. Lokhu kungabangelwa imithi ethile.
• I-Retinoschisis: Ukuhlukaniswa kwezingqimba ze-retina komunye nomunye.

Ngezinye izikhathi, odokotela basebenzisa lokhu (OCT) ukubheka ingaphambili leso, njenge-cornea ne-iris. Lokhu kungasiza ekuboneni amaphutha ngaphambili kweliso noma ukuhlela ukuhlinzwa kwamehlo.

Lolu vivinyo (lwe-OCT) lusebenza kanjani?

Kulula kakhulu. Uke wezwa nge-ultrasound scan? Isebenzisa amaza omsindo ukuthumela emzimbeni bese idala isithombe njengoba ebuyela emuva. I-OCT iyafana, kodwa esikhundleni sokusebenzisa amaza omsindo, isebenzisa ukukhanya okubomvu okungabonakali.Uma le misebe yokukhanya ishaya izicubu ezingaphakathi kweso lakho bese ibuyela emuva, idala izithombe ezinqamula izinhlangothi ezintathu (3D). Lokhu kusho ukuthi ungabona okungaphakathi kweso lakho ngengqimba . Cabanga ngakho njengokusika ikhekhe.

Lokhu akulimazi amehlo nganoma iyiphi indlela. Akukho lutho olungena emehlweni. Kuyindlela ephephile kakhulu.

Kwenzekani ngesikhathi sokuhlolwa (i-OCT)?

Lokhu ukuhlolwa okusheshayo kakhulu okungaqedwa ngemizuzu embalwa nje. Kwenziwa ehhovisi likadokotela wakho. Akukho ukulungiselela okukhethekile okudingekayo. Kungenziwa ngisho nangemva kokuhlolwa kwamehlo okuvamile.

Ngaphambi kokuhlolwa, ungase unikezwe amaconsi amehlo ukuze uvule i-pupil yakho. Lokhu kuzokusiza ukuthi ubone ingaphakathi leso lakho ngokucacile. Uzobe usucelwa ukuthi uhlale phambi kwesithwebuli bese ubeka isilevu sakho esisekelweni esinamathiselwe kuso. Uzocelwa ukuthi ubheke ngqo ekukhanyeni okuluhlaza.

Isikena (i-OCT) siskena iso elilodwa ngesikhathi. Uzobona umugqa obomvu ngesikhathi sokuskena. Ngeke uzwe lutho, futhi akukho lutho oluzoshaya iso lakho. Kuthatha umzuzu owodwa noma emibili ukuskena iso elilodwa. Kubalulekile ukugcina iso lakho lisendaweni eyodwa ngaphandle kokuhambisa ikhanda lakho phakathi nalesi sikhathi. Lena ukuphela kwendlela yokuthola isithombe esicacile.

Ingabe kukhona imiphumela emibi kulokhu?

Cha, ukuhlolwa (kwe-OCT) ngokwako akunazo izingozi noma imiphumela emibi. Kuphephile ngokuphelele. Kodwa-ke, njengoba ngishilo ekuqaleni, uma usebenzisa umuthi wokukhulisa inhlamvu yeso (ukwanda komfundi), ungase uzwe ukungakhululeki okuncane isikhashana ngemva kwalokho. Isibonelo:

• Izwela ekukhanyeni: Lokhu kusho ukuthi amehlo akho angase azizwe eluhlaza okwesibhakabhaka uma uphuma elangeni. Ukugqoka izibuko zelanga kungasiza ekunciphiseni lokhu.
• Umbono ofiphele: Lokhu kubonakala kakhulu uma ubheka eduze.

Lokhu kuvame ukuxazululeka ngokuphelele phakathi namahora ambalwa (cishe amahora angu-4-6). Abanye abantu bangase babe nekhanda elibuhlungu.

Ngakho-ke, uma uhlolwa ngemithi enjalo, kungcono ukuthi omunye umuntu akushayele ekhaya, noma ugweme ukushayela, ngoba kuthatha isikhathi ukuthi umbono wakho ubuyele esimweni esijwayelekile.

Hlobo luni lwemiphumela etholakalayo? Zisitshelani?

Udokotela wakho wamehlo (OCT) uzofunda ngokucophelela izithombe ezithathwe kuskeni. Izithombe zifana nemephu yangaphakathi kweso lakho. Uma uke waskeniwa ngaphambilini, bazoqhathanisa lezi zithombe ezintsha nalezo zithombe ukuze babone ukuthi kube noshintsho, ukuthuthuka, noma ukuqhubeka kwesifo. Bazobe sebekhuluma nawe ngokushesha okukhulu ukuze bakuchazele lokhu.

Le miphumela ingasiza udokotela wakho ukuthi anqume ukuthi unesifo esithinta i-retina noma i-optic nerve yakho, futhi uma kunjalo, ukuthi sesisakazeke kangakanani nokuthi sibi kangakanani. Esebenzisa lolu lwazi, udokotela wakho uzohlela inkambo yakho elandelayo yokwelashwa. Bangase batuse ukuqala imithi, ukwelashwa nge-laser, noma imijovo yamehlo.

Kufanele ngimbone nini udokotela wami?

Kubaluleke kakhulu ukuhlolwa amehlo akho njalo. Vakashela udokotela wakho ngezikhathi ezithile (njalo ezinyangeni ezi-6, kanye ngonyaka, isibonelo). Yilapho udokotela wakho angahlola khona noma yiziphi izinguquko ekuboneni kwakho. Uma unezimpawu ezingavamile noma ubona noma yiziphi izinguquko ekuboneni kwakho, kufanele nakanjani utshele udokotela wakho. Ungakushayi indiva, noma ngabe kuyinto encane.

Uma unezinye zezimpawu ezingezansi, ungesabi futhi ubone udokotela ngokushesha:

• Ubuhlungu bamehlo obusha noma obuqhubekayo.
• Uma unenkinga yokubona ngokucacile, uma indlela imibala ebonakala ngayo isishintshile, noma uma izinto zibonakala zingacacile.
• Uma ubona njalo izinto ezibukeka njengezintanta phambi kwamehlo akho, noma uma ubona ukukhanya.
• Uma ulahlekelwa umbono wakho ngokuzumayo, noma uma ingxenye yombono wakho ibonakala imnyama.

Ngakho-ke, umyalezo wokugcina okufanele uwuthathe uye ekhaya:

Kalula nje, lokhu kuhlolwa (i-OCT) kuyindlela esheshayo, elula, engenabuhlungu, futhi ethuthuke kakhulu. Kuthatha izithombe zengqimba ngengqimba, ezinezinhlangothi ezintathu (3D) zangaphakathi kweso lakho, ikakhulukazi izingxenye ezibucayi ngemuva kweso, njenge-retina kanye ne-optic nerve, futhi kukuvumela ukuthi uzibone kahle njengengxenye eyodwa kweziyinkulungwane zamamilimitha.

Lokhu kuvumela odokotela ukuthi bathathe izilinganiso ngaphakathi kweso, babone umonakalo emsipheni wokubona, futhi bathole izimo ezingase zithinte umbono wakho kusenesikhathi futhi bahlele ukwelashwa. Ngakho-ke, uma udokotela ekucela ukuthi wenze lokhu kuhlolwa, asikho isizathu sokwesaba. Kungaba isinyathelo esibaluleke kakhulu empilweni yamehlo akho nasekulondolozeni umbono wakho oyigugu.

Nakekela amehlo akho! Ungakhohlwa ukuqhubeka nokuhlolwa amehlo akho.
