Uvea ni iki?
Mu magambo make, uvea ni urwego rwo hagati rw'ibice bitatu by'ingenzi bigize ijisho ryacu. Izina ryayo rikomoka ku ijambo ry'ikilatini risobanura "imizabibu." Impamvu ni uko, iyo uyirebye inyuma, iki gice gisa n'imizabibu.
Irindi zina ry'ibi ni 'ikanzu y'imitsi'. Bisobanura 'ishati ifite imitsi y'amaraso.' Izina ryayo ryamenyekanye kuko izunguruka ijisho nk'ishati kandi yuzuyemo imitsi y'amaraso iha ijisho intungamubiri rikeneye.
Mu by'ukuri uvea si igice kimwe. Ni uruvange rw'ibice bitatu by'ingenzi.
- Iris

- Choroid
Ibice by'ingenzi bya uvea n'imikorere yabyo
Ibi bice bitatu by'ijisho bikora imirimo itandukanye ariko y'ingenzi cyane. Reka turebe ibyo ari byo.
| Igice | Urimo gukora iki? |
|---|---|
| Iris | Iki ni cyo gice giha amaso yawe ibara ryayo. Kigena amabara nk'ubururu, umukara n'umukara. Ni kandi uruhererekane rw'imitsi. Igenda irushaho kuba nto kugira ngo igenzure ingano y'urumuri rwinjira mu jisho. Ni nk'aho "aperture" iri kuri kamera. |
| Umubiri w'igishishwa | Ibi biri inyuma y'ijisho ry'amaso. Imitsi iri muri iki gice ihindura imiterere y'ijisho, ibi bidufasha kwibanda neza iyo tureba ikintu kiri hafi yacu cyangwa ikintu kiri kure. Binatanga amazi imbere mu jisho yitwa "aqueous humor". Aya mazi ni yo atuma ijisho rigira imiterere y'uruziga. |
| Choroid | Iki ni cyo gice kinini cya uvea. Ni agace gato kuzuyemo imiyoboro y'amaraso. Tekereza ijisho ryawe nk'inzu. Choroid ni nk'amazi yo mu nzu. Nk'uko amazi yinjira mu nzu agakwirakwizwa ahantu nko mu gikoni no mu bwiherero, choroid ni yo ijyana amaraso mu bice by'ingenzi by'ijisho, cyane cyane retina. Nanone ifite ibara ryijimye kuko irimo ibara ryitwa "melanin." Ibi bigabanya urumuri rutari ngombwa mu jisho. |

Dore zimwe mu ndwara zishobora kugira ingaruka ku ndwara ya uvea:
- Uveitis: Iyi ni yo ndwara ikunze kugaragara cyane kandi ikomeye ifata uvea. Ibice bimwe bya uvea birabyimba.
- Kanseri z'amaso: Cyane cyane iziba mu jisho (intraocular melanoma).
- Indwara ya retina iterwa na diyabete: Abantu barwaye diyabete bashobora kwangirika kw'imitsi y'amaraso mu maso yabo.
- Gucika kw'ijisho: Kwangirika guterwa no kugabanuka kw'amaraso ajya mu jisho.
- Ubuswa: Kutagira ibara rituma uruhu n'amaso bitagira ibara.
- Presbyopia: Ubushobozi bw'ijisho bwo kwibandaho bugabanuka uko umuntu asaza.
- Coloboma: Kutagira igice cy'uruhinja rw'ijisho mu gihe cyo kuvuka.
- Ibikomere by'amaso: Impanuka iyo ari yo yose ishobora kwangiza ururenda.
- Indwara zimwe na zimwe n'izindi ndwara: Indwara zifata izindi ngingo z'umubiri, nka sarcoidosis, zishobora no kugira ingaruka ku maso.
Ni ibihe bimenyetso bisanzwe by'izi ndwara?
Iyo habayeho ikibazo kuri uvea, ibimenyetso bishobora gutandukana bitewe n'igice cya uvea cyafashwe. Ariko hari ibimenyetso bimwe na bimwe biboneka.
| Ibimenyetso | Ibisobanuro byoroshye |
|---|---|
| Kureba nabi | Ingorane yo kutabona ibintu neza. |
| Kubabara amaso | Ububabare buturuka imbere cyangwa hafi y'amaso. |
| Kudakira urumuri (Photophobia) | Kugorwa no kureba urumuri, kumva nk'aho amaso arimo guhinduka ubururu. |
| Ijisho ritukura | Gutukura cyangwa kubyimba kw'igice cy'umweru cy'ijisho. |

| Impinduka mu jisho ry'umukara | Imboni ihindura imiterere iva ku ruziga ijya ku yindi miterere cyangwa ingano. |
| Amaso y'amazi (Epiphora) | Amarira ahora aturuka. |
Ni gute twakwita ku ruhu rw'amaso yacu?
Amaso yacu ni ay'agaciro cyane, bityo hari ibintu bike byoroshye dushobora gukora kugira ngo ijisho ryose, harimo n'ijisho rya uvea, rikomeze kuba rizima.
- Suzuma amaso yawe buri gihe: Ni ngombwa ko buri wese, atari abambara indorerwamo gusa, yisuzumisha amaso nibura rimwe mu mwaka cyangwa ibiri . Ibi bishobora gufasha kumenya ibibazo mbere yuko ibimenyetso bitangira kugaragara.
- Ambara indorerwamo z'umutekano: Ushobora kwirinda impanuka wambaye indorerwamo z'umutekano mu gihe ukata ibyuma, ukoresha ibiti, ukoresha imiti, cyangwa ukina siporo.
- Irinde kunywa itabi no kunywa itabi: Kunywa itabi bishobora kwangiza imiyoboro y'amaraso yoroshye mu maso, ibyo bikaba bigira ingaruka ku buzima bw'inyama zo mu maso.
- Ntugasuzugure indwara z'amaso: IjishoNiba hari ubwandu, gutukura, cyangwa ububabare bumara iminsi irenga mike, jya kwa muganga. Ntureke ngo bikwirakwire maze bibe ikibazo gikomeye.
Ni ibihe bihe byiza byo kujya kwa muganga?
Uretse kwipimisha amaso buri gihe, ugomba guhita ubonana n'umuganga w'amaso mu gihe uhuye n'ibi bikurikira:
- Iyo ibimenyetso by'amaso (ububabare, gutukura, ububobere) bikomeje iminsi irenga mike .
- Niba ibi bimenyetso bikubuza gukora imirimo yawe isanzwe .
- Niba uhuye n'ikibazo cyo kutabona neza cyangwa impinduka .
Icy'ingenzi cyane: Gutakaza amaso mu buryo butunguranye, kutabona neza, cyangwa kwisiga ibara ry'umukara imbere y'amaso bifatwa nk'ikibazo cyihutirwa. Ibi nibibaho, jya ku bitaro bikuru byita ku barwayi ba ETU (ibitaro bikuru biri hafi yawe) .
Uvea ni igice cy'ijisho tudakunze kuvugaho cyane, ariko ni ingenzi ku mikorere yaryo. Ntitumenya akamaro karyo kugeza igihe ritagikora neza. Ariko iyo habayeho ikibazo, gishobora gutera ubwoba cyane. Niyo mpamvu ari ngombwa ko ujya usuzuma amaso yawe buri gihe kandi ukamenya ibimenyetso byaryo.
Ubutumwa bwo kujyana mu rugo
- Uvea ni igice cy'ingenzi cyane cy'ijisho ryawe giha ibara, kigakomeza kureba neza, kandi kigatanga amaraso mu jisho.
- Ntukirengagize ibimenyetso nko gutukura amaso, ububabare, no kutabona neza. Bishobora kuba ikimenyetso cy'ikibazo cya uveitis.
- Indwara nyinshi zishobora kumenyekana hakiri kare iyo wisuzumishije amaso yawe nibura rimwe mu mwaka.
- Iyo utakaje amaso yawe mu buryo butunguranye cyangwa ukagira impinduka ikomeye mu maso yawe, ni ikibazo cyihutirwa. Jya ku bitaro byita ku barwayi ba ETU byihutirwa.
