Kua whakaaro koe ki te āhua o te tae o ō kanohi? Me pēhea rānei te arotahi o ō kanohi ki tētahi mea e tata ana, ki tētahi mea rānei e tawhiti ana? Ko te uvea tētahi wāhanga o te kanohi e whai wāhi ana ki tēnei katoa, pērā i tētahi miihini iti i roto i te kanohi. Me kōrero poto tātou mō tēnei i tēnei rā.
He aha te Uvea?
Ki te kī māmā noa iho, ko te uvea te paparanga waenga o ngā paparanga matua e toru e hanga ana i tō tātou kanohi. I ahu mai tōna ingoa i te kupu Latina mō te "karepe". Ko te take o tēnei, ina tirohia mai i waho, he rite te āhua o tēnei wāhanga ki te karepe.
Ko tētahi atu ingoa mō tēnei ko te 'tunika toto'. Ko tōna tikanga he 'hāte he uaua toto tōna.' Nā te mea e takai ana i te kanohi pērā i te hāte, ā, kua whakakiia ki ngā uaua toto e whakarato ana i ngā matūkai e hiahiatia ana e te kanohi.
Ehara te uvea i te wāhanga kotahi. He huinga o ngā wāhanga matua e toru.
- Ārihi
- Tinana kiriuhi
- Koroiti
Ngā wāhanga matua o te uvea me ā rātou mahi
He rerekē ngā mahi a ēnei wāhanga e toru o te kanohi, engari he tino hira. Me titiro tātou ki ēnei.
| Wāhanga | Kei te aha koe? |
|---|---|
| Ārihi | Koinei te wāhanga e homai ana te tae ki ō kanohi. Mā tēnei ka whakatau i ngā tae pēnei i te kikorangi, te parauri, me te mangu. He mowhiti uaua anō hoki. Ka nui haere, ka iti haere hei whakahaere i te nui o te mārama e tomo ana ki te kanohi. He rite ki te "pūwhera" o te kāmera. |
| Tinana kiriuhi | Kei muri i te iris tēnei. Ka whakarerekē ngā uaua o tēnei wāhanga i te āhua o te karu o te kanohi, ā, ka āwhina i a tātou ki te arotahi mārama ina titiro tātou ki tētahi mea e tata ana ki a tātou, ki tētahi mea rānei e tawhiti ana. Ka puta hoki te wai i roto i te kanohi e kiia nei ko te "waikawa wai". Ko tēnei wai te mea e homai ana ki te kanohi tōna āhua porowhita. |
| Koroiti | Koinei te wāhanga nui rawa atu o te uvea. He kiriuhi angiangi kua whakakiia ki ngā uaua toto. Whakaarohia tō kanohi he whare. He rite te choroid ki ngā paipa wai o te whare. Pērā i te wai e tomo ana ki te whare, ka tohatohahia ki ngā wāhi pēnei i te kīhini me te kaukau, ko te choroid te kaituku toto ki ngā wāhanga tino nui o te kanohi, inā koa te retina. He pōuri hoki te tae nā te mea kei roto he tae e kiia nei ko te "melanin." Mā tēnei ka whakaitihia te whakaata koretake o te mārama ki roto i te kanohi. |
He aha ngā āhuatanga hauora ka pā ki te uvea?
Nā te mea he kohinga o ngā wāhanga e toru te uvea, he maha ngā momo āhuatanga ka pā ki a ia. Ahakoa he iti noa iho ētahi āhuatanga, ka pā kino ētahi ki tō tirohanga.
Kei raro nei ētahi o ngā āhuatanga ka pā ki te uvea:
- Uveitis: Koinei te mate tino noa, tino kino hoki e pā ana ki te uvea. Ka mumura ētahi wāhanga o te uvea.
- Ngā mate pukupuku kanohi: Ina koa ko ērā e puta ana i roto i te kanohi (intraocular melanoma).
- Te retinopathy e pā ana ki te mate huka: Ka pāngia pea ngā oko toto o ngā kanohi o te hunga mate huka.
- Whiu kanohi: Te kino i puta mai i te hekenga o te rere o te toto ki te kanohi.
- Te mate kiriuhi: Te korenga o te tae e homai ana he tae ki te kiri me ngā kanohi.
- Presbyopia: Ka heke te kaha o te arotahi o te karu i te pakeketanga.
- Coloboma: Te ngaronga o tētahi wāhanga o te uvea i te whānautanga.
- Ngā Whara Kanohi: Ka taea e tetahi momo aituā te kino i te uvea.
- Ētahi mate pāwera me ētahi atu mate: Ko ngā mate e pā ana ki ētahi atu wāhanga o te tinana, pērā i te sarcoidosis, ka pā hoki ki ngā kanohi.
He aha ngā tohu noa o ēnei mate?
Ina he raruraru kei te uvea, ka rerekē pea ngā tohu i runga i te wāhanga o te uvea e pāngia ana. Heoi, tera ētahi tohu noa ka kitea.
| Tohu | He whakaahuatanga māmā |
|---|---|
| Te tirohanga pōuri | Te āhua o te kore e mārama te kite i ngā mea. |
| Mamae kanohi | Te mamae e puta mai ana i roto, i te taha rānei o ngā kanohi. |
| Te aro nui ki te mārama (Photophobia) | He uaua ki te titiro ki te mārama, me te mea kei te kikorangi ngā kanohi. |
| Kanohi whero | Te whero, te mumura rānei o te wāhanga mā o te kanohi. |
| Te ngaronga o te tirohanga | Te ngaronga ohorere, te ngaro haere rānei o te tirohanga. |
| Ngā huringa o te kanohi pango | Ka huri te āhua o te tauira mai i te porowhita ki tētahi āhua, ki tētahi rahi rānei. |
| Ngā kanohi wai (Epiphora) | Kei te heke tonu mai ngā roimata. |
Me pēhea tā tātou tiaki i te uvea o ō tātou kanohi?
He tino taonga ō tātou kanohi, nō reira he iti noa ngā mea māmā ka taea e tātou te mahi hei pupuri i te hauora o te kanohi katoa, tae atu ki te uvea.
- Tirohia ō kanohi i ia wā: He mea nui kia tirohia ō kanohi e te katoa, kaua ko te hunga e mau ana i ngā mōhiti anake, i te iti rawa i te kotahi, i ngā tau e rua rānei . Mā tēnei ka āwhina i te tautuhi i ngā raruraru i mua i te puta o ngā tohu.
- Mauria ngā mōhiti haumaru: Ka taea e koe te ārai i ngā aituā mā te mau i ngā mōhiti haumaru ina tapahi ana i te konganuku, ina mahi ana ki te rakau, ina mahi ana ki ngā matū, ina takaro hākinakina rānei.
- Āta karohia te momi hikareti me te whakamahi tupeka: Ka taea e te momi hikareti te kino i ngā uaua toto ngawari o ngā kanohi, ka pā tika tēnei ki te hauora o te uvea.
- Kaua e whakaititia ngā mate kanohi: KanohiMena he mate pāwera, he whero, he mamae rānei e roa ana i ngā rā torutoru, me toro atu ki te tākuta. Kaua e tukua kia horapa, kia nui ake ai te raruraru.
He aha ngā wā pai rawa atu hei toro atu ki te tākuta?
Haunga ngā whakamātautau kanohi auau, me toro atu koe ki tētahi tākuta kanohi i runga i te wā tonu mēnā ka pāngia koe e tētahi o ēnei e whai ake nei:
- Mena ka roa ake ngā tohu o te kanohi (mamae, whero, pōuri) mō ngā rā maha .
- Mena ka aukati ēnei tohu i a koe ki te mahi i ō mahi o ia rā .
- Mena ka pāngia koe e tētahi momo ngaronga tirohanga, e tētahi panoni rānei .
He mea tino nui: Ko te ngaronga ohorere o te tirohanga, te pōuri ohorere o te tirohanga, te pango rānei o te mata i mua i ngā kanohi, e kiia ana he āhuatanga ohorere hauora. Mēnā ka puta tēnei, haere tonu ki te Tari Ohorere o te hōhipera tata (ETU) .
Ko te uvea tētahi wāhanga o te kanohi kāore e tino kōrerohia ana, engari he mea nui ki tana mahi. Kāore tātou e mōhio ki tōna uara kia kore rā anō e mahi tika. Engari ina puta he raruraru, ka tino whakamataku. Koia te mea nui kia tirohia ō kanohi i ia wā, kia mōhio hoki ki ngā tohu.
