Ese wigeze witegereza amaso yawe mu ndorerwamo? Iyo uyarebye, ubona ko hari igice cy'uruziga giha amaso yawe ibara ryiza. Hari abantu bagira ibara ry'umukara wijimye, abandi bafite ibara ry'umukara woroshye, kandi rimwe na rimwe rishobora kuba ubururu cyangwa icyatsi kibisi. Icyo gice cy'ibara ni cyo twita mu buvuzi 'iris'. Ni nk'urutoki rwawe. Ni umwihariko kuri wowe. Nta wundi muntu ku isi ufite ibara ry'amaso nk'iryo.
Ni iyihe nshingano nyayo y'iris?
Mu magambo make, inshingano nyamukuru y'iris ni ukugenzura ingano y'urumuri rwinjira mu jisho ryawe. Ni nk'umwobo uri muri lenzi ya kamera. Urabona ako kadomo gato k'umukara kari hagati mu jisho ryawe? Tukabyita imboni. Umucyo mu by'ukuri winjira mu jisho ryawe unyuze muri iyo mboni.
Rero, imitsi yoroshye cyane iri mu jisho ni yo igenzura ingano y'iyi mpeta y'umukara.
- Iyo ugiye ahantu hari izuba kandi hafite urumuri rwinshi: Imitsi iri mu jisho ituma iris iba ntoya uko bishoboka kose (yifatana) . Hanyuma urumuri rukenewe ni rwo rwonyine rwinjira mu jisho. Umucyo mwinshi unyuramo ukangiza ijisho.
- Iyo ugiye ahantu hijimye kandi hatagaragara neza: Indorerwamo y'ijisho yongera (yagura) iris, ikemerera urumuri rwinshi rushoboka kwinjira mu jisho, ikagufasha kubona neza ibintu bikukikije.
Tekereza winjiye mu nzu umaze igihe uri ku zuba, ukumva umeze nk'aho ntacyo ubona, sibyo? Bifata igihe kugira ngo amaso yawe amenyere umwijima. Ni bwo mboni yawe igenda yaguka buhoro buhoro ikamenyera umwijima. Ibi byose bibaho mu buryo bwikora, utanabizi .
Ibi biri he imbere mu jisho?
Amaso yacu ameze nk'igitunguru. Agizwe n'ibice byinshi by'ijisho. Iri iri munsi y'ijisho, ari na ryo gice cy'ijisho gisobanutse, no hejuru y'ijisho, riri imbere mu jisho. Ni ukuvuga ko igice cy'ibara giherereye hafi y'uruziga rw'umukara.
Ibi bikozwe n'iki? Ibara ry'amaso rigenwa gute?
Isosi y'amaso igizwe ahanini n'imitsi n'imitsi. Ibi bikora mu buryo bwikora, nta bushobozi bwacu bwo kubigenzura.
Noneho reka turebe uko ibara ry'amaso rikorwa. Ushobora kuba warumvise ibara karemano ryitwa "Melanin" riha uruhu rwacu n'umusatsi wacu ibara. Ibara ry'amaso rigenwa n'ingano y'iryo bara rya melanini mu mboni y'ijisho.
- Iyo melanin ari nyinshi: amaso ahinduka umukara wijimye.
- Iyo melanin iri hasi: Amaso ashobora kuba ari umukara woroshye, icyatsi kibisi, cyangwa ubururu.
Ingano ya melanin dufite iterwa n'uturemangingo twacu. Ibi bivuze ko uhabwa iyi mico na nyoko na so .
Ni ibihe bintu bigira ingaruka ku ibara ry'amaso (iris)?
Indwara iyo ari yo yose ifata ijisho ishobora no kugira ingaruka ku njyana y'ijisho. Dore zimwe mu ndwara zikunze kugaragara.
| Imiterere | Mu magambo make ... |
|---|---|
| Aniridia | Kuba indorerwamo y'ijisho idafite burundu cyangwa igice cyayo igihe umuntu yavukaga. |
| Indwara ya Horner | Kwangirika k'umutsi wo mu maso bishobora gutera ibimenyetso nko kugira ijisho rito ry'umukara n'ijisho rinanutse. |
| Glaucoma | Ubwiyongere bw'umuvuduko imbere mu jisho bushobora kwangiza imitsi y'amaso. Ibi bishobora no kugira ingaruka ku mikorere y'indorerwamo y'ijisho. |
| Ubuswa bw'abalubino | Umubiri ufite ibara rike cyane rya melanin cyangwa nta na rimwe rifite, ibyo bigatuma amaso agira ibara ryoroheje cyane. |
| Indwara z'amaso | Gupfuka kw'indorerwamo y'ijisho. Ibi bigira ingaruka ku buryo butaziguye ku kureba. |
| Uveitis | Kubyimba k'urwego rwo hagati rw'ijisho, harimo n'ikirahuri. Amaso ashobora gutukura no kubabara. |
| Indwara ya Waardenburg | Indwara y’uturemangingo itera impinduka mu ibara ry’amaso, uruhu n’umusatsi, ndetse rimwe na rimwe no kubura amatwi. |
Igikuru ni uko niba ubonye ikintu nk'impinduka mu kureba kwawe, ububabare, cyangwa impinduka mu ibara ry'amaso yawe, ugomba guhita ubonana na muganga .
Bigenda bite iyo iris yangiritse?
Impanuka iyo ari yo yose igera ku jisho ishobora kwangiza indorerwamo y'ijisho. Imiterere y'ibyangiritse biterwa n'uburyo impanuka yagenze. Hari imvune nto zishobora kuvurwa hakoreshejwe uburyo bwo kuruhuka no mu rugo. Ariko, zimwe muri zo zishobora kwangiza bikomeye ndetse no kutabona neza .
Kubwibyo, niba hari akaga ku maso, ikintu cyiza wakora ni ukubonana n'umuganga w'amaso. Urugero, niba ibintu bikomeye, niba uhita uta ubwenge cyangwa ukagira ububabare bukabije, jya mu ishami ryita ku bibazo byihutirwa (ETU) ry'ibitaro biri hafi yawe vuba aha.
Ni ibihe bizamini bikorerwa kugira ngo harebwe imiterere y'amaso?
Iyo ugiye kwisuzumisha amaso bisanzwe, umuganga w'amaso azasuzuma n'indorerwamo yawe. Bashobora gukoresha igikoresho cyihariye cyitwa "Slit Tamp" kugira ngo babikore.
Iyo hari ukeka ko hari ikibazo cy’uburwayi, ibizamini nk’ibi bishobora kuba ngombwa ko bikorwa kugira ngo byemezwe neza.
| Ikizamini | Ibisobanuro |
|---|---|
| MRI (Ishusho ya Magnetic Resonance) | Gushaka amashusho arambuye y'imbere mu mubiri hakoreshejwe imbaraga za rukuruzi. |
| Gupima CT (Isuzuma rya mudasobwa) | Gufata amashusho y'imbere mu jisho hakoreshejwe ikoranabuhanga rya X-ray. |
| Ultrasound | Gusuzuma imiterere y'ijisho hakoreshejwe amajwi. |
| Tomografia y'Ubushobozi bwo Guhuza Ishusho (OCT) | Gukoresha imiraba y'urumuri kugira ngo ubone amashusho asobanutse neza kandi arambuye ya retina n'ibindi bice by'ijisho. |
None se, twakwitaho dute uru rugingo rw'agaciro?
Amaso yacu ni yo mutungo w'agaciro kacu. Kurikiza izi ntambwe zoroshye kugira ngo urinde ijisho ryawe ryose, harimo n'ijisho.
- Ambara indorerwamo z'izuba: Igihe cyose ugiye ku zuba, ambara indorerwamo z'izuba nziza zifite uburinzi bwa UV 100% cyangwa icyapa cya UV400 . Ibi bizarinda amaso yawe imirasire ya ultraviolet (UV) yangiza izuba.
- Shaka inama kwa muganga ukimara kubona impinduka: Niba ubonye impinduka mu maso yawe, nko kubabara mu maso cyangwa gutukura, hita ugana muganga aho gutegereza kureba. Bishobora kuba ibintu byoroshye nko guhindura indorerwamo zawe, cyangwa bikaba ikimenyetso cy'indwara ikomeye.
- Mu gihe cy’impanuka: Niba uhita uta ubwenge, ukagira ububabare bukabije, cyangwa ukagira igikomere gikomeye mu jisho , jya ku bitaro byita ku barwayi ba ETU .
Ese Iris Scanners muri terefone zibangamira amaso?
Muri iki gihe, ikoranabuhanga ryo gupima isura n'amaso (Iris Scanners) rikunze gukoreshwa cyane mu gufungura ibintu nka telefoni na mudasobwa. Ibi bikoresho bikumenya binyuze mu gutanga urumuri ruto cyane, rutagaragara rwa infrared ku maso yawe no ku maso yawe. Dukurikije ubushakashatsi buriho ubu, nta bimenyetso bigaragaza ko ibi bikoresho biteje akaga cyangwa konona amaso . Bityo rero nta mpamvu yo kubitinya.
Hanyuma, iris yawe si ikintu kidasanzwe kuri wewe gusa kandi giha amaso yawe ibara ryiza. Ni igice cy'ingenzi cyane kigufasha kubona neza mu gihe cy'urumuri urwo ari rwo rwose. Bityo rero jya usuzuma amaso yawe buri gihe kandi uyafate neza.
Ubutumwa bwo kujyana mu rugo
- Iris ni igice cy'ijisho ryawe giha ibara ryacyo kandi ni umwihariko kuri wowe.
- Inshingano yayo nyamukuru ni ukugenzura urumuri rwinjira mu jisho.
- Buri gihe wambara indorerwamo z'izuba nziza kugira ngo urinde amaso yawe imirasire y'izuba yangiza.
- Niba ubonye impinduka mu kureba, ububabare, cyangwa ikindi kibazo kidasanzwe, gana muganga vuba.
- Mu gihe habaye impanuka cyangwa gutakaza ubushobozi bwo kureba butunguranye, jya kwa muganga wita ku barwayi ba ETU byihutirwa.
- Indwara nyinshi z'amaso zishobora kumenyekana hakiri kare binyuze mu kwipimisha amaso buri gihe.
