Retina - E aʻo e pili ana i ka hana mana liʻiliʻi e pale ai i kou ʻike

ʻIke ʻoe i nā mea nani o kēia ao, ʻike i nā helehelena o kāu poʻe aloha, a heluhelu i kahi puke me kou mau maka, ʻeā? He mea kupaianaha maoli ko kākou mau maka. E like me ke kāmela ʻenehana kiʻekiʻe. No laila, i loko o kēia kāmela, aia kahi kiʻiʻoniʻoni e hoʻololi i ka mālamalama i kiʻi, a i ʻole kahi sensor i nā kāmela hou. I ka lāʻau lapaʻau, kapa mākou i kēia ʻo retina . I kēia lā, e aʻo hou kākou e pili ana i kēia hana mana liʻiliʻi he mea nui i kou ʻike.

I ka ʻōlelo maʻalahi, he aha ka retina?

He papa lahilahi loa ka retina o nā hunaola nerve ma ke kua o kou maka. Ke nānā ʻoe i kekahi mea, komo ka mālamalama mai kēlā mea i kou maka a hāʻule pololei ma luna o kēia retina.

E noʻonoʻo ʻoe e nānā ana i kahi pua nani. Hele nā ​​kukuna mālamalama i hōʻike ʻia mai ka pua ma o ke aniani o kou maka a kau ʻia ma ka retina. A laila hana ʻia kekahi mea kupaianaha. Hoʻololi nā pūnaewele kūikawā i loko o ka retina (kapa mākou i kēia mau photoreceptors ) i kēia mālamalama i nā hōʻailona aʻalolo uila. E like me ka hoʻololi ʻana o kahi sensor kāmela i ka mālamalama i ʻikepili kikohoʻe.

A laila hele pololei kēia mau hōʻailona aʻalolo i ka lolo ma o kahi aʻalolo kūikawā i kapa ʻia ʻo ke aʻalolo optic. Hoʻopili ka lolo i kēia mau hōʻailona a haʻi iā ʻoe, "ʻAuē... he rose ʻulaʻula kēia." Hana ʻia kēia kaʻina holoʻokoʻa i ka ʻimo o ka maka. ʻAʻole anei he mea kupaianaha?

He aha nā ʻāpana nui ʻelua o ka retina?

Hiki ke hoʻokaʻawale ʻia ko kākou retina i ʻelua ʻāpana nui. He ʻokoʻa nā hana a lāua ʻelua.

1. Macula: ʻO kēia ka ʻāpana liʻiliʻi o ka retina ma waenakonu e hāʻawi ana i ka ʻike ʻoi loa. Kōkua ka macula iā ʻoe e hana i nā mea maikaʻi e like me ka heluhelu ʻana i kahi puke me ka maopopo, ka ʻike ʻana i nā ʻano helehelena, ka hoʻokele ʻana i kahi kaʻa, a me ke kaula ʻana i kahi nila. He mea nui loa kēia ʻāpana no ka ʻike maopopo ʻana i nā kala.

2. Retina Peripheral: ʻO kēia ka mea a mākou e kapa nei ʻo ka ʻāpana nui a puni ka macula. Hāʻawi kēia ʻāpana iā mākou i ka ʻike peripheral. E noʻonoʻo ʻoe e hele ana ma ke alanui e nānā pololei ana i mua. Hiki iā ʻoe ke ʻike maopopo i ke kanaka i mua ou ma muli o ka macula. I ka manawa like, ʻaneʻane ʻaʻole hiki iā ʻoe ke ʻike i kahi kaʻa a i ʻole ke kaʻa paikikala e hele mai ana mai ka ʻaoʻao. Hāʻawi ʻia kēlā ʻike peripheral e ka retina peripheral. ʻO kēia ʻāpana hoʻi e kōkua iā ʻoe e ʻike i nā mea i ka pōʻeleʻele.

Nā maʻi maʻamau a me nā kūlana e pili ana i ka retina

ʻO ka mea pōʻino, aia kekahi mau maʻi e hiki ke hōʻino i ko kākou retina makamae. Hiki i kekahi o kēia mau mea ke alakaʻi i ka nalowale mau loa o ka ʻike inā ʻaʻole mālama koke ʻia. No laila he mea nui e makaʻala i kēia.

He aha nā hōʻailona e hōʻike ana i kahi pilikia me ka retina?

Inā ʻike ʻoe i kekahi mau loli i kou mau maka a i ʻole ka ʻike, mai hoʻowahāwahā iā ia. Inā loaʻa iā ʻoe kekahi a ʻoi aku paha o kēia mau hōʻailona, ​​e ʻike i ke kauka, ʻoiai he kauka maka, i ka hikiwawe loa.

Pehea e nānā ai ke kauka i ka retina?

Ke ʻike ʻoe i kahi ophthalmologist, e hoʻohana ʻo ia i nā ʻano hana like ʻole e nānā ai i kāu retina.

• Dilation: E kau kāu kauka i kekahi mau kulu o ka lāʻau lapaʻau i loko o kou maka e hoʻonui i kāu pupil i hiki iā ʻoe ke ʻike maopopo i kou retina . Hiki ke blurry iki kou ʻike no kekahi mau hola ma hope.
• Hoʻokolohua Kukui ʻoki: Hoʻohana ʻia kahi microscope kūikawā a me ke kukui e nānā i ke alo holoʻokoʻa o ka maka, mai ke kua a i ka retina.
• Fundoscopy / Ophthalmoscopy: He mea hana lima e hoʻomālamalama i ka maka e nānā i ka retina, ke aʻalolo optic, a me nā kīʻaha koko.
• Kiʻi Fundus: Lawe kahi kāmela kūikawā i nā kiʻi hoʻonā kiʻekiʻe o ka retina. He mea nui loa kēia no ka nānā ʻana i nā kūlana maʻi.

Pehea e hiki ai iā mākou ke mālama i ko mākou retina?

ʻAʻole mākou e ʻōlelo wale aku "e pale i kou mau maka e like me nā maka ʻelua". No laila, e hana pono i kēia mau mea e mālama i kou mau retina, ka mea e pale ai i kou ʻike.

• E nānā pinepine i kou mau maka: Inā ʻoe e kau ana i nā aniani a i ʻole, e nānā ʻia kou mau maka e ke kauka maka ma ka liʻiliʻi i hoʻokahi manawa i ka makahiki a ʻelua paha .
• Inā loaʻa iā ʻoe ka maʻi diabetes a i ʻole ke koko kiʻekiʻe: ʻOiai ʻo kēia mau maʻi e hoʻopilikia pololei i nā maka, he mea nui e nānā ʻia kou mau maka i hoʻokahi manawa i ka makahiki . E kāohi i kou maʻi e like me ka ʻōlelo a kāu kauka.
• E kiʻi i ka meaʻai maikaʻi: He mea maikaʻi loa nā meaʻai waiwai i nā wikamina A, C, E, a me ka zinc no nā maka. E hoʻokomo i nā mea kanu ʻōmaʻomaʻo (spinach, kale), kāloti, ʻuala, ʻalani, a me ka iʻa i kāu papaʻai.
• E mālama i ke kaumaha olakino: ʻO ke kāohi ʻana i ke kaumaha o ke kino e kōkua i ka pale ʻana i nā maʻi e like me ka maʻi diabetes a me ke koko kiʻekiʻe.
• E pale i kou mau maka mai ka lā: E ʻaʻahu i nā aniani maka maikaʻi e pale aku ai i nā kukuna UV ke hele ʻoe i waho. Mai nānā pololei i ka lā.
• E ʻaʻahu i nā aniani palekana: E hōʻoia e ʻaʻahu i nā aniani palekana i nā kūlana i loaʻa ai ka pilikia i kou mau maka, e like me ka pāʻani ʻana i nā haʻuki, ka wili ʻana, a i ʻole ka hana ʻana me nā mīkini.
• Mai hoʻowahāwahā i nā loli i kou ʻike: ʻOiai inā manaʻo ʻoe e hōʻino mālie ana kou ʻike, mai manaʻo wale he hōʻailona ia o ka ʻelemakule. E ʻike i ke kauka e ʻike i ke kumu.

Nā kūlana ke pono ʻoe e ʻike koke i ke kauka!

He mea nui loa kēia. Inā loaʻa iā ʻoe kekahi o kēia mau mea, mai hoʻonele i ka manawa a hele i ka haukapila kokoke loa ʻo Emergency Treatment Unit (ETU) . He mau hōʻailona paha kēia o kahi pilikia, e like me ka retina i hemo. Hiki i ka mālama koke ke hoʻōla i kou ʻike.

ʻO ka hoʻowahāwahā ʻana i kēia mau hōʻailona hiki ke alakaʻi i ka makapō mau loa. No laila, mai hopohopo a hopohopo paha, a e ʻimi koke i ke kōkua lapaʻau.
