Iyi koroidi iri mu jisho ni iki? Reka tubimenye neza!

Ese wigeze wibaza ukuntu amaso yacu akora mu buryo butangaje? Ijisho ni urugingo rugoye cyane kandi rufite agaciro. Uyu munsi rero tugiye kuvuga ku gice cy'ijisho kitazwi cyane, ariko gifite akamaro cyane. Icyo ni koroidi. Ushobora kuba utari warigeze wumva iri zina mbere. Ariko nta kibazo, uyu munsi turarivugaho mu buryo bworoshye, mu buryo ushobora kumva.

Choroid ni iki? Ni iyihe serivisi itanga ku jisho?

Mu magambo make, choroid ni urwego rwo hagati rw'ijisho ryawe, urukuta rw'inyuma rw'ijisho ryawe. Ni urw'inyuma. Mu by'ukuri, choroid ni imwe mu mitsi y'amaraso ikomeye itanga amaso yacu. Ifasha kandi kugenzura ingano y'urumuri rwinjira mu jisho. Bityo rero, choroid ni ingenzi cyane mu buryo tubona isi.

Choroid ifite imirimo ibiri y'ingenzi:

1. Guha ijisho amaraso akenewe.

2. Kumenya urumuri rwinjira mu jisho.

Noneho reka tuvuge kuri ibi bibiri mu buryo burambuye .

1. Amaraso akwira mu jisho

Iyi ni yo nshingano nyamukuru ya choroid. By'umwihariko, ni yo itanga amaraso kuri retina no ku mutsi w'amaso yacu. Tekereza, iyi retina n'umutsi w'amaso bihora byohereza ibimenyetso mu bwonko. Ni nk'imashini ebyiri zikora zidahagarara. Rero, ibi bice bibiri bikenera amaraso menshi n'intungamubiri kurusha izindi ngingo z'ijisho. Choroid ifite imiyoboro myinshi y'amaraso, nk'aho igongana. Niyo mpamvu ishobora gutanga ingano nyayo y'amaraso ikenewe.

2. Gufata urumuri

Indi nshingano y'ingenzi ya choroid ni ukwinjiza urumuri. Iki si ikintu kigaragara cyane, ariko ni ingenzi cyane.

Ese wari uzi ko koroidi irimo ibara ryitwa melanin ku bwinshi kurusha izindi ngingo zose mu maso yacu? Iyi melanin iboneka no mu ruhu rwacu. Ni iyi melanin ikura imirasire ya ultraviolet ituruka ku zuba kandi ikarinda uruhu rwacu ibintu nka kanseri y'uruhu. Melanin ishobora gukuraho imirasire ya ultraviolet gusa, ndetse n'urumuri hafi ya rwose rugaragara.

Melanine mu jisho ikora nk'ifuro ry'amajwi, rikoreshwa mu kwinjiza amajwi. Ushobora kuba warabonye ubwoko bw'ifuro ku nkuta za studio zifata amajwi. Ibuza amajwi kwiruka no kumvikana. Muri ubwo buryo, melanini mu jisho ibuza urumuri gukwirakwira mu jisho. Ibi birinda uturemangingo tw'ifotora mu jisho ryacu kwangizwa n'urumuri rudakenewe. Ibi ni ingenzi cyane kugira ngo umuntu abone neza.

Koroidi iherereye he? Igaragara ite?

Choroid iherereye inyuma ya bibiri bya gatatu by'ijisho ryacu. Mu by'ukuri, iherereye munsi y'urukuta rw'inyuma rw'ijisho rwera (twita sclera) no hejuru ya retina, ari na yo urwego rupima urumuri inyuma y'ijisho. Ubunini bwa choroid bushobora gutandukana kuva kuri milimetero 0.1 (mm) kugeza kuri milimetero 0.22. Ni ukuvuga, hafi y'ubunini bw'impapuro zisanzwe zicapwa.

Ku bijyanye n'ishusho ya choroid, ni ahantu huzuye imitsi y'amaraso . Nanone, ifite ibara ryijimye bitewe na melanin irimo. Igitangaje ni uko, kimwe n'uruhu rwacu, choroid ishobora kugira ibibara byo kuvuka cyangwa utudomo dusanzwe (twitwa nevi). Ibi ntibigaragara inyuma. Abantu benshi bamenya ko bafite iyo umuganga w'amaso abasuzumye.

Ni ibihe bintu bishobora kugira ingaruka kuri koroidi?

Ikibabaje ni uko hari indwara nyinshi zishobora kugira ingaruka kuri koroidi. Ibi bishobora guterwa n'ibintu bitandukanye, kuva ku ndwara ziterwa n'imiyoboro y'amaraso kugeza ku ndwara ziterwa n'ububyimbirwe. Dore ingero nke:

• Albinism : Kubura ibara rya melanin bishobora gutera ibibazo byo kureba no kumva urumuri.
• Indwara zo kuvuka (kuvuka igihe cyo kuvuka) : Urugero, indwara nka choroideremia zishobora kwangiza retina.
• Indwara ya retinopathy iterwa na diyabete .
• Kugaragara neza kw'imitsi mu maraso no kwangirika kw'amagufwa mu maso (cyane cyane imiterere yayo y'ubutose).
• Kanseri z'amaso : cyane cyane melanoma yo mu maso.
• Ischema y'amaso : Ibi ni ukugabanuka kw'amaraso atembera mu jisho. Urugero, indwara yo mu jisho.
• Glaucoma itera kwangirika k'imitsi y'amaso na retina .
• Ibikomere byo mu maso .
• Indwara zo kubyimba : Indwara nka uveitis cyangwa chorioretinitis.

Niba hari ikibazo kuri koroidi, ni ibihe bimenyetso bishobora kugaragara?

Niba ufite ikibazo kijyanye na koroidi, ushobora kugira ibimenyetso bimwe na bimwe. Ibi birimo:

• Uduce twijimye mu kureba (Scotomas) cyangwa ubusembwa bw'aho umuntu abona.
• Kubona nabi .
• Kureba kabiri (Diplopia).
• Kubabara amaso.
• Kuribwa umutwe.
• Kumva urumuri (amaso y'ubururu) (Photophobia)
• Kutabona neza.

Niba ubonye ibi bimenyetso, hita ubonana na muganga!

Hari ibimenyetso bimwe na bimwe bigaragaza indwara ikomeye cyane cyangwa yihutirwa . Muri ibyo bihe, ni ngombwa gushaka inama kwa muganga byihuse.

Ibi ni ibimenyetso bisaba kwitabwaho byihutirwa:

* Isesemi no kuruka hamwe n'ububabare bw'amaso/umuvuduko.

* Kubona impeta z'amabara y'umukororombya zikikije urumuri.

* Gutakaza ubushobozi bwo kureba mu buryo ubwo aribwo bwose .

* Umucyo utunguranye ugaragara imbere y'amaso (Photopsias).

Niba wumva ibintu nk'ibi, nyamuneka gana muganga vuba .

Ni ibihe bipimo biboneka kugira ngo hamenyekane ibibazo bya choroid?

Iyo ugiye kwisuzumisha amaso buri gihe, umuganga w’amaso ashobora kubona impinduka muri koroyide binyuze mu bice bito bya retina, cyangwa agasobanukirwa imiterere ya koroyide binyuze mu mpinduka muri retina ubwayo. Byongeye kandi, hari ibizamini byinshi byihariye bishobora gufasha gusuzuma koroyide no gusuzuma indwara zijyanye nayo. Ibyo ni ibi bikurikira:

• Ikizamini cyo kureba neza : Iki ni ikizamini cyo kureba neza uko ubona.
• Ibipimo byo kureba no kubona ibintu mu buryo bwimbitse.
• Isuzuma ry'itara rikozwe mu buryo bwa "slit light" : Gusuzuma ijisho hakoreshejwe mikorosikopi yihariye.

Bitewe n'isano iri hagati ya choroid na retina, bimwe mu bizamini bisuzuma retina nabyo bishobora gufasha kumenya imiterere ya choroid. Urugero:

• Angiografiya ya fluorescein
• Angiografiya y'icyatsi kibisi ya Indocyanine
• Tomografia y'Ubushobozi bwo Guhuza Ishusho (OCT)

Ibi bizamini bishobora gufasha muganga wawe gusobanukirwa neza imiterere y'amaso yawe.

Ni ubuhe buryo bwo kuvura indwara zifata koroidi?

Kenshi na kenshi, hari uburyo buke bwo kuvura bugira ingaruka ku maraso. Ahubwo, indwara itera maraso iravurwa . Rero, uburyo bwo kuvura bushobora gutandukana cyane bitewe n'indwara. Dore ingero nke:

• Uburyo bwo kuvura Albino : Kubera ko albino ari indwara iterwa n'uturemangingo, ntabwo ishobora kuvurwa mu buryo butaziguye. Ubuvuzi bugamije kugabanya ibimenyetso.
• Imiti irwanya glaucoma : Iyi igabanya umuvuduko w'ijisho imbere kandi ikarinda kwangirika kw'ingingo ziri kuri koroidi no hafi yayo.
• Imiti igabanya ubushyuhe : Iyi miti igabanya ubushyuhe. Ishobora gutangwa mu buryo bw'umubiri cyangwa mu buryo bwihariye mu jisho.
• Imiti irwanya imitsi y'amaraso (VEGF) : Iyi miti irwanya imitsi y'amaraso irinda kuremwa kw'imitsi mishya y'amaraso.
• Uburyo bwo kuvura kanseriKimwe n'izindi kanseri, kanseri y'amaso ishobora gukenera kuvurwa nko kubagwa, imiti ivura indwara ya kanseri, ndetse no kuvurwa hakoreshejwe imirasire.
• Imiti ifasha/ituma amaraso atembera neza : Ibi birimo ibintu byinshi, nko kugabanya amaraso (anticoagulants) n'imiti igenzura umuvuduko w'amaraso.
• Kubagwa amaso : Hari indwara zimwe na zimwe zigira ingaruka kuri koroidi zisaba kubagwa kugira ngo zikosorwe.

Bitewe n'ikibazo cyawe, hari ubundi buryo bwo kuvura bushobora kugufasha. Umuganga w'amaso cyangwa undi muganga w'ubuvuzi ashobora kukubwira byinshi kuri ubu buryo bwo kuvura no kugufasha guhitamo uburyo bukubereye.

Ni iki twakora kugira ngo choroid yacu ikomeze kugira ubuzima bwiza?

Hari ibintu byinshi ushobora gukora kugira ngo amaso yawe akomeze kuba mazima, harimo n'ubuzima bwa choroid yawe. Icy'ingenzi muri ibi ni ukwipimisha amaso buri gihe . Ibi bireba buri wese, si abambara indorerwamo gusa.

Byongeye kandi, ibindi bintu ushobora gukora ni ibi bikurikira:

• Ambara ibikingira amaso . Mu gihe ukora akazi ako ari ko kose, ambara indorerwamo z'umutekano cyangwa amadarubindi yagenewe ako kazi. Ibi ni ingenzi cyane cyane mu gihe ukoresha ivumbi cyangwa imiti.
• Irinde gukoresha nikotine . Kunywa itabi, kunywa inzoga, no guhekenya itabi byose bishobora kugira ingaruka ku mikorere y'amaraso, ibyo bikaba byanangiza amaso yawe.
• Gucunga indwara zidakira . Niba ufite indwara ishobora kugira ingaruka ku maso yawe cyangwa ku mikorere y'amaraso, nka diyabete cyangwa umuvuduko ukabije w'amaraso, kuyicunga neza bishobora gufasha gukumira cyangwa gutinza kwangirika kw'amaso yawe.
• Ite ku buzima bwawe muri rusange . Kugira ibiro byiza no kugira indyo yuzuye ni ingenzi kugira ngo amaso yawe agire ubuzima bwiza bushoboka.

Amaherezo, ibintu byo kwibuka

Sawa, rero ndizera ko ubu usobanukiwe neza na choroid twavuganye uyu munsi.

Wibuke ko retina yawe ari yo imenya urumuri ikaruhindura ibimenyetso by'amaso byoherezwa mu bwonko bwawe. Kugira ngo ibi bishoboke, retina ikenera amaraso menshi kandi adahindagurika. Rero, choroid yawe ni yo ijyana amaraso menshi muri retina yawe no mu mitsi y'amaso. Choroid inafasha gucunga urumuri rwinjira mu maso yawe. Ibi bituma retina yoroherwa no gutunganya urwo mucyo neza.

Choroid ishobora kuba idazwi cyane nk'ibindi bice by'ijisho. Ariko ni igice cy'ingenzi kandi cy'ingenzi cyane mu kureba kwacu . Mu buzima bwawe bwa buri munsi, hari ibintu byinshi ushobora gukora kugira ngo wite ku buzima bwa choroid yawe - ndetse n'amaso yawe muri rusange. Rero, ni byiza gutekereza ku kwita ku maso yawe, sibyo?
