Te Ao i Roto i te Kanohi: Me Ako Tātou mō te Choroid e Whakaora Ana i Tā Tātou Tirohanga

Kua whakaaro kē koe me pēhea te mahi a ō tātou kanohi pērā i te kāmera tino pai? Ko ngā mea katoa e kitea ana e tātou, arā, ngā tae, te māramatanga, ngā āhua, ka tukuna katoatia ēnei ki te roro i roto i ngā hēkona ruarua, ka taea ai e tātou te kite i tēnei ao. I roto i tēnei kanohi iti, kei reira tētahi toa iti nei te mōhiotia e tino hiahiatia ana mō tō tātou tirohanga, engari kāore tātou e kōrero nui mōna. Koinei te mea e kiia nei e tātou ko te 'Choroid'.

E rua ngā wāhanga matua o te mahi a te choroid ki ō tātou kanohi.

1. Te Putanga Toto

Koinei te mahi tino nui, tino nui hoki o te choroid. He rite ki te tipu hiko matua e tuku ana i te wai me te hiko ki te tāone. Ko te retina me te io whatu i roto i ō tātou kanohi he rite ki ngā wheketere e rua e mahi tonu ana. Nā te mea kei te tuku tonu rātou i ngā tohu ki te roro, he nui ake te toto me te kai e hiahiatia ana e rātou i ērā atu kiko.

Nō reira, kei roto i tēnei koroiroi he whatunga o ngā uaua toto angiangi, e whakatakotoria ana tetahi ki runga i tetahi. Mā roto i tēnei pūnaha uaua toto ka whiwhi tonu te retina me te io whatu i te hāora me ngā matūkai. Mēnā ka iti haere noa iho tēnei hāora, ka tino kino te tirohanga.

2. Te mimiti māramatanga

I ētahi wā, pērā i ngā tohu whānau i runga i tō tātou kiri, ka taea hoki e tēnei choroid te whai tohu whānau (nevi). Kāore e taea e tātou te kite i ēnei mai i waho.

• Ngā āhuatanga whānau: Hei tauira, ko ngā āhuatanga pēnei i te choroideremia ka pā kino ki te retina.
• Te retinopathy e pā ana ki te mate huka: Ka taea e te mate huka te kino i ngā oko toto i roto i te kanohi, ka pā hoki ki te choroid.
• Te pirau o te kanohi: Ina koa i te momo 'māku', ka tupu ngā uaua toto hou, ngoikore i roto i te choroid, ka kino pea te tirohanga.
• Matepukupuku kanohi: Ka puta pea ngā matepukupuku, inā koa ko te melanoma intraocular, i roto i te choroid.
• Te ischemia kanohi: Te ngoikore o te rere o te toto ki te kanohi, pērā i te whiu kanohi.
• Glaucoma: Ina pakaru te io whatu me te retina i te pikinga o te pēhanga i roto i te kanohi, ka pāngia hoki te choroid e te pānga ā-kore.

• Angiography fluorescein: Ka werohia he tae motuhake ki roto i te uaua i te ringa, ā, ka tangohia he whakaahua o ngā oko toto i roto i te kanohi.
• Te Tomography Whārite Ātaahua (OCT): He rite tēnei ki te tango i tētahi matawai whakawhiti-wāhanga o roto o te kanohi. Ka taea te tirotiro i te matotoru o ngā paparanga o te kanohi, me te tirotiro mēnā he pupuhi kei roto.
