Isi Imbere mu Ijisho: Reka Twige Ku byerekeye Choroid Itanga Ubugingo ku Iyerekwa Ryacu

Ese wigeze wibaza uburyo amaso yacu akora nka kamera ikomeye? Ibyo tubona byose, ni ukuvuga amabara, urumuri, imiterere, byose byoherezwa mu bwonko mu masegonda make, bigatuma tubona iyi si. Muri iri jisho rito, hari intwari itazwi cyane, ariko ntabwo tuyivugaho cyane. Ni cyo twita 'Choroid'. Nubwo izina ritangaje gato, akazi karyo ni ingenzi cyane. Reka tubiganireho mu buryo bworoshye kandi bwiza uyu munsi.

Mu magambo make, iyi koroidi ni iki?

Tekereza ko ijisho ryacu ari umupira ugizwe n'ibice bitatu. Igice cyo hagati cyitwa uvea. Choroid ni igice cy'ingenzi cyane cy'icyo gice cyo hagati. Inshingano yacyo nyamukuru ni ugutanga amaraso, ari na yo ntungamubiri zikenewe n'ibindi bice by'ingenzi by'ijisho ari ingenzi ku kureba kwacu. Byongeye kandi, binafasha kugenzura ingano y'urumuri rwinjira mu jisho no kuduha kureba neza.

Ni iyihe mirimo ibiri y'ingenzi ya choroid?

Serivisi itangwa na choroid ku maso yacu ishobora kugabanywamo ibice bibiri by'ingenzi.

1. Itangwa ry'amaraso

Iyi ni yo nshingano y'ingenzi kandi y'ingenzi ya koroidi. Imeze nk'uruganda rutanga amazi n'amashanyarazi mu mujyi . Retina n'imitsi y'amaso biri mu jisho ryacu ni nk'inganda ebyiri zikora ubudahagarara. Kubera ko zihora zohereza ibimenyetso mu bwonko, zikenera amaraso menshi n'indyo kurusha izindi ngingo.

Rero, imbere muri iyi koroidi hari urusobe rw'imitsi mito y'amaraso , ifatanye hejuru y'indi. Ni muri urwo rwego rw'imitsi y'amaraso aho retina n'imitsi y'amatwi bihabwa umwuka wa ogisijeni n'intungamubiri bidashira. Iyo uwo mwuka ugabanutseho gato, ubushobozi bwacu bwo kureba bushobora kwangirika cyane.

2. Gufata urumuri

Iyi ni imikorere izwi cyane, ariko ifite akamaro kanini. Ese wigeze ubona ifuro ry'umukara rifite imyenge rifata ku nkuta za studio zifata amajwi kugira ngo ribuze amajwi kumvikana? Ibyo ni byo koko koroidi ikora imbere mu jisho.

Ushobora kuba warumvise melanin , ibara rituma uruhu rwacu rugira ibara ry'umukara. Iyi melanin iboneka ku bwinshi muri koroyide. Melanin ikoreshwa mu ruhu mu kurinda imirasire yangiza y'izuba.Irinda uruhu binyuze mu kwinjiza imirasire ya UV. Imbere mu jisho, iyi melanin irinda urumuri rwinjiramo gukwirakwira mu jisho bitari ngombwa.

Iyi koroidi iherereye he?

Choroid iherereye inyuma ya bibiri bya gatatu by'ijisho ryacu. Muri make, iherereye hagati y'urukuta rw'umweru rw'ijisho ryacu (sclera) n'urwego rw'imbere rw'ijisho, retina . Imeze nk'urwego rwo hagati rw'isahani.

Uru ni agahu gato cyane. Ni ukuvuga ko gafite ubunini nk'urupapuro rwa A4 dusanzwe ducapa. Ariko imbere muri ubwo bunini buto hari urusobe runini rw'imitsi y'amaraso navuze. Rimwe na rimwe, nk'uko tugira ibibara ku ruhu rwacu, iyi koroidi ishobora no kugira ibibara ku ruhu (nevi). Ntitushobora kubibona inyuma. Ibi bibonwa gusa iyo umuganga w'amaso asuzumye amaso.

Ni ibihe bintu bishobora kugira ingaruka kuri koroidi?

Ibintu byinshi bigira ingaruka ku gutembera kw'amaraso mu mubiri wacu, nk'indwara zo kubyimba, nabyo bishobora kugira ingaruka kuri koroidi. Kubera ko igizwe gusa n'imitsi y'amaraso. Zimwe mu ndwara z'ingenzi zishobora kugaragara ni izi:

• Albinism: Indwara ya genetiki igabanya ibara rya melanin mu ruhu no mu maso. Uku kubura melanin bituma amaso adashobora kwihanganira urumuri (photophobia) kandi bigatera ubumuga bwo kutabona neza.
• Indwara zo mu nda: Urugero, indwara nka choroideremia zishobora kwangiza retina.
• Indwara ya retina iterwa na diyabete: Diyabete ishobora kwangiza imiyoboro y'amaraso mu jisho, ibyo bikaba byanagira ingaruka kuri koroidi.
• Kwangirika kw'amagufwa y'amaraso: Cyane cyane iyo imiyoboro y'amaraso imeze nk'iy'amazi, imiyoboro mishya y'amaraso idakomeye ikurira muri koroyide, ibi bikaba byangiza ubushobozi bwo kureba.
• Kanseri z'amaso: Kanseri, cyane cyane melanoma yo mu maso, zishobora kugaragara muri choroid.
• Ischemia y'amaso: Amaraso adakora neza mu jisho, urugero nko mu gihe cyo gucika intege mu jisho.
• Glaucoma: Iyo umuvuduko wiyongereye mu jisho wangiza imitsi y'amaso na retina, choroid nayo ishobora kwibasirwa mu buryo butaziguye.
• Ibikomere byo mu maso.
• Indwara zo kubyimba: Kubyimba no kwandura imbere mu jisho, nka uveitis cyangwa chorioretinitis.

Ni gute wamenya ikibazo kiri muri koroidi?

Iyo hari ikibazo kuri koroidi, bigira ingaruka ku buryo butaziguye ku buryo tubona. Kubwibyo, ni ngombwa cyane kwitondera impinduka iyo ari yo yose mu iyerekwa.

Ni ibihe bipimo bikorwa kugira ngo hamenyekane bene ibyo bibazo?

Iyo ugiye kwa muganga w’amaso, azabaza ibimenyetso byawe kandi asuzume amaso yawe. Niba bakeka ko hari ikibazo kuri koroidi, bashobora gukora ibizamini bikurikira:

• Ikizamini cy'ubuhanga bwo kureba: Ikizamini rusange gipima ubukana bw'amaso yawe.
• Ikizamini cyo kureba: Ikizamini cyo kureba niba hari ikibazo mu bushobozi bwawe bwo kureba (urugero ushobora kurebamo utanyeganyeje umutwe).
• Isuzuma ry'itara rikozwe mu buryo bwa "slit tamp": Muri ibi, muganga asuzuma neza imbere mu jisho ryawe akoresheje igikoresho cyihariye gisa na mikorosikopi.
• Ibizamini byo gufata amashusho ya retina: Bitewe n'isano iri hagati ya choroid na retina, gusuzuma retina bishobora no gutanga amakuru kuri choroid.
• Isuzuma rya fluorescein angiography: Irangi ridasanzwe rishyirwa mu mitsi iri mu kuboko, hanyuma hagafatwa amashusho y'imitsi y'amaraso iri mu jisho.
• Isuzuma ry’imiterere y’ijisho (OCT): Ibi ni nko gupima imbere mu jisho. Rishobora kugenzura ubunini bw’ijisho ndetse no kureba niba hari ikibyimba.

Ni ubuhe buryo bwo kuvura indwara zifitanye isano na koroidi?

Akenshi, aho kuvura choroid mu buryo butaziguye, indwara itera iyi ndwara iravurwa. Ibi bivuze ko iyo impamvu ivuwe, imiterere ya choroid nayo irushaho kuba myiza. Uburyo bwo kuvura bushobora gutandukana cyane bitewe n'indwara.

Bitewe n'uko indwara yawe imeze, ushobora gukenera ubundi buryo bwo kuvura, muganga wawe akagusobanurira birambuye.

Ni gute wakomeza ubuzima bwa choroid n'amaso?

Amaso yacu ni umutungo w'agaciro gakomeye. Bityo twese tugomba kugerageza kuyarinda. Hari ibintu byinshi ushobora gukora kugira ngo ijisho ryose rikomeze kugira ubuzima bwiza, harimo na choroid.

• Suzuma amaso yawe buri gihe: Waba wambaye indorerwamo cyangwa utambaye, ni ngombwa ko muganga w'amaso agusuzuma nibura rimwe mu mwaka. Muri ubwo buryo, ibibazo byose bishobora kumenyekana mbere yuko ibimenyetso bigaragara.
• Rinda amaso yawe: Niba urimo gusudira, ukoresha imiti, cyangwa ukorera ahantu hari ivumbi, menya neza ko wambaye indorerwamo/amataratara yo kwirinda.
• Irinde kunywa itabi no kurinywa: Kunywa itabi no kurihekenya byangiza urusobe rw'amaraso mu buryo butaziguye. Kubera ko koroidi ari igice cy'imitsi y'amaraso, kunywa itabi bishobora kubyangiza mu buryo butaziguye.
• Gucunga indwara zidakira: Niba ufite indwara nka Diyabete Mellitus na Hypertension , zicunge neza ukurikije amabwiriza ya muganga. Niba izi ndwara zidacunzwe, kwangirika kw'amaso bishobora kuba bikomeye cyane.
• Ite ku buzima bwawe muri rusange: Kurya indyo yuzuye, kugira ibiro byiza, no gukora imyitozo ngororamubiri buri gihe, ntabwo ari byiza ku maso yawe gusa, ahubwo no ku mubiri wawe wose.

Choroid ni igice cy'ijisho ryacu kidatuje, ariko gifite akamaro kanini. Gitanga ubuzima ku kureba kwacu kandi kikadufasha kubona isi neza. Rero, ni inshingano zacu kubimenya no kwita ku maso yacu.
