He aha kēia choroid i loko o ka maka? E ʻike pono kākou!

Ua noʻonoʻo paha ʻoe i ke ʻano kupaianaha o ka hana ʻana o ko kākou mau maka? He ʻōkana paʻakikī a waiwai nui ka maka. No laila, i kēia lā e kamaʻilio mākou e pili ana i kahi ʻāpana i ʻike ʻole ʻia, akā he mea nui loa o ka maka. ʻO ia ka choroid. ʻAʻole paha ʻoe i lohe i kēia inoa ma mua. Akā, ʻaʻohe pilikia, i kēia lā e kamaʻilio maʻalahi mākou e pili ana iā ia, ma ke ʻano hiki iā ʻoe ke hoʻomaopopo.

He aha ka choroid? He aha ka lawelawe āna e hāʻawi ai i ka maka?

I ka ʻōlelo maʻalahi, ʻo ka choroid ka papa waena o kou maka, ka paia waho o kou maka. No ka uvea ia. I ka pololei, ʻo ka choroid kekahi o nā kīʻaha koko nui e hoʻolako i ko mākou mau maka. Kōkua pū ia i ka hoʻomalu ʻana i ka nui o ka mālamalama e komo i loko o ka maka. No laila, he mea nui loa ka choroid i ke ʻano o kā mākou ʻike ʻana i ke ao nei.

ʻElua mau hana nui o ka choroid:

1. Ke hoʻolako ʻana i ka maka me ke koko e pono ai.

2. Ka omo ʻana o ke kukui e komo ana i ka maka.

I kēia manawa, e kamaʻilio kākou e pili ana i kēia mau mea ʻelua me nā kikoʻī hou aku .

1. Ka lako koko i ka maka

ʻO kēia ka hana nui o ka choroid. ʻO ka mea nui, ʻo ia ka mea e hoʻolako i ke koko i ka retina a me ke aʻalolo optic i loko o ko kākou mau maka. E noʻonoʻo, ke hoʻouna mau nei kēia retina a me ke aʻalolo optic i nā hōʻailona i ka lolo. Ua like ia me ʻelua mau mīkini e hana mau ana. No laila, pono kēia mau ʻāpana ʻelua i ka nui o ke koko a me nā meaʻai ma mua o nā ʻiʻo ʻē aʻe o ka maka. He nui nā kīʻaha koko o ka choroid, e like me ka tangle. ʻO ia ke kumu e hiki ai iā ia ke hāʻawi pololei i ka nui o ke koko e pono ai.

2. Ka omo ʻana o ka mālamalama

ʻO kekahi hana koʻikoʻi o ka choroid, ʻo ia ke omo ʻana i ka mālamalama. ʻAʻole kēia he mea maopopo loa, akā he mea nui loa ia.

Ua ʻike anei ʻoe aia i loko o ka choroid kahi pigment i kapa ʻia ʻo melanin ma nā nui he nui ma mua o nā ʻiʻo ʻē aʻe i loko o ko kākou mau maka? Loaʻa pū kēia melanin i loko o ko kākou ʻili. ʻO kēia melanin ka mea e omo ai i nā kukuna ultraviolet ʻino mai ka lā a pale i ko kākou ʻili mai nā mea e like me ke kanesa ʻili. Hiki i ka Melanin ke omo ʻaʻole wale i nā kukuna ultraviolet, akā, kokoke i nā kukui ʻike ʻia a pau.

Hana ka Melanin i loko o ka maka e like me ka huʻa acoustic, kahi i hoʻohana ʻia e omo i ke kani. Ua ʻike paha ʻoe i kēia ʻano huʻa ma nā paia o nā keʻena hoʻopaʻa leo. Hoʻōki ia i ke kani mai ka lele ʻana a puni a me ke kani ʻana. Ma ke ʻano like, hoʻōki ka melanin i loko o ka maka i ka mālamalama mai ka hoʻopuehu ʻana i loko o ka maka. Pale kēia i nā cell photoreceptor i loko o ko kākou retina mai ka hōʻino ʻia e ka mālamalama pono ʻole. He mea nui loa kēia no ka ʻike maopopo.

Aia ma hea ka choroid? Pehea kona ʻano?

Aia ka choroid ma nā hapakolu ʻelua o ko kākou maka. I ka pololei, aia ia ma lalo o ka paia keʻokeʻo o waho o ka maka (ka mea a mākou e kapa nei he sclera) a ma luna o ka retina, ʻo ia ka papa ʻike kukui ma ke kua o ka maka. Hiki ke ʻokoʻa ka mānoanoa o ka choroid mai 0.1 millimeters (mm) a i kahi o 0.22 mm. ʻO ia hoʻi, e like me ka mānoanoa o kahi pepa paʻi maʻamau.

No ke ʻano o ka choroid, he wahi ia i piha i nā kīʻaha koko . Eia kekahi, he ʻeleʻele kona kala ma muli o ka melanin i loko. ʻO ka mea kupaianaha, e like me ko kākou ʻili, hiki i ka choroid ke loaʻa nā māka hānau a i ʻole nā ​​kiko maʻamau (i kapa ʻia ʻo nevi). ʻAʻole ʻike ʻia kēia mau mea iā kākou mai waho. ʻIke wale ka hapa nui o ka poʻe he loaʻa iā lākou ke nānā aku kahi kauka maka i ko lākou mau maka.

• ʻO ka Tomography Hoʻohui Optical (OCT)

Hiki i kēia mau hoʻokolohua ke kōkua i kāu kauka e hoʻomaopopo maikaʻi i ke kūlana o kou mau maka.

He aha nā lāʻau lapaʻau no nā maʻi e hoʻopilikia ana i ka choroid?

I ka hapanui o nā hihia, ʻaʻohe lāʻau lapaʻau e pili pono ana i ka choroid. Akā, ua mālama ʻia ke kūlana kumu e hoʻopilikia nei i ka choroid . No laila, hiki ke ʻokoʻa loa nā ʻano lapaʻau ma muli o ke kūlana. Eia kekahi mau laʻana:

• Lapaʻau no ka Albinism : ʻOiai he maʻi hoʻoilina ka albinism, ʻaʻole hiki ke mālama pololei ʻia. ʻO ka manaʻo o ka lāʻau lapaʻau ka hōʻemi ʻana i nā hōʻailona.
• Nā lāʻau lapaʻau anti-glaucoma : Hoʻemi kēia i ke kaomi ma mua o ka maka a pale i ka hōʻino ʻana i nā ʻano ma luna a puni ka choroid.
• Nā lāʻau lapaʻau anti-inflammatory : Hoʻemi kēia mau lāʻau i ka mumū. Hiki ke hāʻawi ʻia ma ke ʻano ʻōnaehana a i ʻole i ka maka.
• Nā lāʻau anti-vascular endothelial growth factor (VEGF) : Pale kēia mau lāʻau anti-VEGF i ke kūkulu ʻia ʻana o nā kīʻaha koko hou.
• Nā lāʻau lapaʻau maʻi kanesaE like me nā ʻano maʻi kanesa ʻē aʻe, pono paha ka maʻi kanesa maka i ka mālama ʻana e like me ke ʻoki ʻana, ka chemotherapy, a me ka radiation therapy.
• Nā lāʻau lapaʻau e kōkua/hoʻomaikaʻi i ke kahe koko : Hoʻokomo pū kēia i nā mea he nui, e like me nā mea hoʻokahe koko (anticoagulants) a me nā lāʻau lapaʻau e kaohi ai i ke koko.
• Nā ʻoki maka : Pono kekahi mau kūlana e hoʻopilikia i ka choroid i ke ʻoki ʻana e hoʻoponopono iā lākou.

Ma muli o kou kūlana maʻamau, hiki ke hāʻawi ʻia aku nā lāʻau lapaʻau ʻē aʻe. Hiki i kāu kauka maka a i ʻole kekahi mea mālama ola kino ke haʻi hou aku iā ʻoe e pili ana i kēia mau lāʻau lapaʻau a kōkua iā ʻoe e koho i ka mea kūpono loa iā ʻoe.

He aha kā mākou e hana ai e mālama i ke olakino o ko mākou choroid?

Aia kekahi mau mea hiki iā ʻoe ke hana e mālama i ke olakino o kou mau maka, me ke olakino o kou choroid. ʻO ka mea nui o kēia mau mea, ʻo ia ka loaʻa ʻana o nā hoʻokolohua maka maʻamau . Pili kēia i nā kānaka a pau, ʻaʻole wale ka poʻe e ʻaʻahu ana i nā aniani maka.

Eia kekahi, ʻo nā mea ʻē aʻe hiki iā ʻoe ke hana:

• E ʻaʻahu i ka pale maka . Ke hana ʻoe i kekahi hana, e ʻaʻahu i nā aniani palekana a i ʻole nā ​​goggles i hana kūikawā ʻia no kēlā hana. He mea nui loa kēia i ka wā e hana ana me ka lepo a i ʻole nā ​​​​​​kemika.
• E hōʻalo i ka hoʻohana ʻana i ka nikotine . Hiki i ka puhipaka, ka vaping, a me ka nau ʻana i ka paka ke hoʻopilikia i kāu ʻōnaehana kahe koko, hiki ke hōʻino i kou mau maka.
• E mālama i nā maʻi maʻi mau . Inā loaʻa iā ʻoe kahi maʻi e hiki ke hoʻopilikia i kou mau maka a/a i ʻole ke kaʻina hana hoʻopuni koko, e like me ka maʻi diabetes a i ʻole ke koko kiʻekiʻe, ʻo ka mālama pono ʻana i kēlā maʻi e hiki ke kōkua i ka pale ʻana a i ʻole ka hoʻopaneʻe ʻana i ka hōʻino hou ʻana i kou mau maka.
• E mālama i kou olakino holoʻokoʻa . ʻO ka mālama ʻana i ke kaumaha olakino a me ka loaʻa ʻana o ka meaʻai kūpono he mea nui ia no ka mālama ʻana i ke olakino maka maikaʻi loa.

ʻO ka mea hope loa, nā mea e hoʻomanaʻo ai

ʻAe, ke lana nei koʻu manaʻo ua ʻike maikaʻi ʻoe i ka choroid a mākou i kamaʻilio ai i kēia lā.

E hoʻomanaʻo, ʻo kou retina ka mea e ʻike ai i ka mālamalama a hoʻololi iā ia i mau hōʻailona ʻike maka i hoʻouna ʻia i kou lolo. No ka hana ʻana i kēia, pono ka retina i kahi lako koko mau a nui. No laila, ʻo kou choroid ke kumu nui o ke koko i kou retina a me ke aʻalolo optic. Kōkua pū ka choroid i ka hoʻokele ʻana i ka mālamalama e komo ana i kou mau maka. ʻO kēia ka mea e maʻalahi ai i ka retina ke hana pono i kēlā mālamalama.

ʻAʻole paha i ʻike nui ʻia ka choroid e like me nā ʻāpana ʻē aʻe o ka maka. Akā, he ʻāpana koʻikoʻi a koʻikoʻi loa ia o kā mākou ʻike . I kou ola o kēlā me kēia lā, nui nā mea hiki iā ʻoe ke hana e mālama i ke olakino o kou choroid - a me kou mau maka holoʻokoʻa. No laila, he mea maikaʻi ke noʻonoʻo e pili ana i ka mālama ʻana i kou mau maka, ʻeā?

ʻO Choroid, olakino maka, retina, aʻalolo optic, melanin, maʻi maka, nā hoʻāʻo maka
