Ua ʻike anei ʻoe e pili ana i kēia pale liʻiliʻi i loko o kou maka? E kamaʻilio kākou e pili ana i ka cornea!

Ke nānā ʻoe i kou maka i loko o ke aniani, aia kahi ʻāpana ʻālohilohi a piʻo e like me ke aniani ma ke alo, ʻeā? ʻO ia ka mea a mākou e kapa nei he cornea. E like me ka makani o ke kaʻa, ua like kēia me kahi pale pale e pale ai i nā mea e like me ka lepo a me nā germs mai ke komo ʻana i loko o ko mākou mau maka. Eia kekahi, he mea nui loa ke ʻano o kēia cornea no mākou e ʻike maopopo ai.

Aia ka cornea ma ke alo o kahi keʻena piha wai i loko o ka maka (ʻo ia hoʻi ka 'anterior chamber'). Ma ka ʻaoʻao o ia mea ʻo ka iris a me ka pupil. ʻO ka ʻāpana keʻokeʻo o ka maka e hoʻopuni ana i ka cornea ua kapa ʻia ʻo sclera. ʻOiai ʻo ka cornea ka mea pale mua o ko kākou maka, hiki ke hōʻino maʻalahi ʻia e nā ulia a me nā ʻeha. Akā, ʻo ka mea kupaianaha, hiki i ka cornea ke ho'ōla koke iā ia iho, ʻoiai mai nā ʻeha liʻiliʻi.

He aha nā papa o ka cornea?

E noʻonoʻo he ʻeono (6) papa o kēia cornea liʻiliʻi i hoʻopaʻa ʻia ma luna o kekahi. E like me ke aniani laminated, hana pū kēia mau papa e hoʻoikaika i ka cornea.

• ʻEpithelium: ʻO kēia ka papa waho loa o ka cornea. Hana ia e like me ka paia, e pale ana i nā germs a me ka lepo mai ke komo ʻana i ka maka. He ʻoluʻolu loa kēia papa i ka ʻeha. Ua ʻōlelo ʻia he 300-600 mau manawa ka nui o nā mea loaʻa ʻeha ma aneʻi ma mua o ko mākou ʻili. ʻO ia ke kumu hiki i kahi ʻāpana lepo liʻiliʻi ke hoʻoulu i ka ʻeha hiki ʻole ke hoʻomanawanui i ko mākou mau maka. Mālama kēlā ʻano ʻike i ko mākou mau maka.

• ʻO ka papa Bowman: He papa ikaika kēia i hana ʻia me ka collagen. Kōkua ia i ka cornea e mālama i kona ʻano.

• Stroma: ʻO kēia ka papa mānoanoa loa o ka cornea. ʻAʻole ia e hoʻoikaika wale i ka cornea, akā kōkua pū kekahi i ka hoʻohuli ʻana i ka mālamalama e komo ana i ka maka a hoʻopili pololei iā ia ma ka retina.

• Papa Pre-Descemet (PDL): Ua kapa ʻia kēia ʻo "papa Dua." Ua hōʻike ʻia e ka noiʻi he pale ikaika kēia ʻaʻole hiki i ka ea ke hele ma waena. He papa hou kēia, i ʻike ʻia i ka makahiki 2013 wale nō.

• ʻO ka papa o Descemet: He papa lahilahi kēia, palupalu, akā ikaika loa. He mea nui loa ia i ka pale ʻana i loko o ka maka mai ka hōʻino a me ka maʻi.

• Endothelium: ʻO kēia papa ke kuleana nui no ka mālama ʻana i ke kaulike o ka wai i loko o ka cornea. Hoʻomalu ia i ka nui o ka wai e pono ai no ka hana pono ʻana o ka stroma.

ʻO nā maʻi a me nā pilikia e hoʻopilikia pinepine ai i ka cornea

ʻOiai ʻo ia ka mea pale o ko mākou mau maka, hiki i ka cornea ke loaʻa i nā maʻi like ʻole, nā ʻeha, a me nā maʻi puʻupuʻu.

• Maka maloʻo:ʻO ka epithelium, ʻo ia ka papa waho loa o ka cornea, pono i nā waimaka e hana pono ai. Hoʻomālū nā waimaka i ka maka a kōkua iā ia e omo i ka oxygen mai ka lewa. He ʻeha nā maka maloʻo a hiki ke hoʻopilikia i ka ʻike.

• Nā maʻi: Inā he pōʻino i ka ʻili o ka cornea, hiki i nā germs - me nā virus, bacteria, fungi, a me nā parasites - ke komo maʻalahi a hoʻoulu i nā maʻi.

• Keratitis: ʻO nā maʻi, nā ulia, a me nā maʻi ʻē aʻe e hiki ke hoʻoulu i ka cornea e pehu, ʻulaʻula, a ʻeha. Ua kapa ʻia kēia he keratitis.

• Nā ʻeha: E like me ka pale makani o ke kaʻa, hiki ke hōʻino ʻia ka cornea e nā mea o waho. Hiki i kēia ke hana i nā ʻōpala, nā ʻokiʻoki, a me nā ʻōpū.

• Ka pōʻino o ke kaiapuni: ʻO ke anu nui, ka wela, nā kemika (wai a kinoea paha), a me ka radiation UV hiki ke hōʻino i ka cornea.

• Nā Maʻi Kūkulu (Dystrophies): Hoʻololi kekahi mau maʻi i ke ʻano a me ke kūkulu ʻana o ka cornea. Ua kapa pinepine ʻia kēia mau mea he 'corneal dystrophies'. ʻO Keratoconus lāua ʻo Fuchs' dystrophy ʻelua mau maʻi like.

He aha nā lāʻau lapaʻau no kēia mau kūlana?

ʻOkoʻa nā koho lapaʻau ma muli o ka pilikia me ka cornea. Na kāu kauka e hoʻoholo i ka lāʻau lapaʻau i kūpono loa i kou kūlana.

• Lapaʻau Maʻalahi: No ka maloʻo iki a i ʻole ka ʻeha ʻoluʻolu ʻole i nā maka, hiki i kāu kauka ke ʻōlelo i kahi mea e like me nā kulu maka maʻalahi.
• Nā lāʻau lapaʻau: Hoʻohana ʻia nā lāʻau lapaʻau, ʻoi aku hoʻi no nā mea e like me nā maʻi. Hiki ke hele mai kēia mau mea ma ke ʻano o nā kulu maka a i ʻole nā ​​​​​​mea ʻaila, a i ʻole he mau pila āu e lawe ai.
• Ka hoʻopili ʻana i ka maka: I kekahi manawa e noi ʻia ʻoe e ʻaʻahu i kahi pale maka e pale i kou maka a hiki i ka ho'ōla ʻana o ka cornea.
• ʻO nā ʻoki laser: He ʻano ʻoki e hoʻoponopono ai i ka ʻike. Maanei, hoʻohana ʻia kahi kukuna laser e hoʻololi i ke ʻano o ka cornea. He ʻano ʻoki kaulana ʻo LASIK .
• ʻO ke ʻoki maka: Pono paha ke ʻoki ʻana e hoʻoponopono i ka hōʻino ʻia o ka cornea a i ʻole e hoʻoponopono i kekahi mau kūlana olakino.
• Hoʻoili Cornea: I ka hala ʻana o ka manawa, hiki i ka cornea ke lilo i ao a i ʻole hiki ʻole ke pelu pono i ka mālamalama. I nā hihia koʻikoʻi, pono paha e wehe ʻia ka cornea i hōʻino ʻia a hoʻoili ʻia kahi cornea olakino.

Pehea e pale ai i kou cornea mai nā pōpilikia?

"ʻOi aku ka maikaʻi o ka pale ʻana ma mua o ka hoʻōla ʻana," wahi a lākou. He ʻoiaʻiʻo 100% kēlā no ko mākou mau maka. ʻO ke kau ʻana i nā aniani palekana a i ʻole nā ​​goggles ke ala maikaʻi loa e pale ai i ka cornea mai nā ulia. Hiki i kēia mea liʻiliʻi ke pale aku i nā pōʻino nui e hiki ke hana i loko o kekona.

E hōʻoia e komo i nā aniani palekana i nā manawa e like me kēia:

• I ka wā e hana ana me nā mīkini a me nā mea hana: ʻOiai ke hoʻohana ʻana i nā mea hana lima liʻiliʻi ma ka home, he mea nui ia i ka wā e hana ai me kahi mea e like me ka wili a i ʻole ka wili.
• I ka wā e hana ana i loko o ka māla: I ka wā e ʻokiʻoki ai i ka lau nahele a i ʻole e hoʻohana ana i ka chainsaw, hiki i nā pōhaku liʻiliʻi, ka lepo, a me nā ʻoki mauʻu ke lele i loko o kou mau maka.
• I ka hoʻohana ʻana i nā kemika: ʻAʻole pili i ka akahele o kāu hoʻohana ʻana i nā huahana hoʻomaʻemaʻe hale e like me ka bleach a me ka mea hoʻomaʻemaʻe lua, hiki nō iā lākou ke komo i loko o kou mau maka.
• I ka hana ʻana me ke ahi a me ka wela loa: E pale i kou mau maka mai ka uahi a me ka wela mai ke ahi.
• ʻOiai e pāʻani ana: Ma nā haʻuki i pāʻani ʻia me ka pōpō wikiwiki, e like me ka cricket, tennis, a me ka hockey.
• Ke hōʻike ʻia i ka lā nui: Ke noho ʻoe ma ke kahakai a i ʻole ma kahi hau, hiki i nā kukuna UV i hōʻike ʻia mai ka wai a me ka hau ke puhi i ka cornea. Ua kapa ʻia kēia he photokeratitis . E hoʻohana i nā aniani maka me ka pale UV maikaʻi.

He aha kāu e hana ai inā komo kekahi mea i kou maka?

ʻO ka mea nui loa, ʻaʻole e hopohopo inā komo kahi mea e like me ka lepo a i ʻole ka lepo i loko o kou maka. Eia kekahi mau mea e pono ai a me nā mea ʻaʻole e pono ai.

Inā loaʻa iā ʻoe kēia mau hōʻailona, ​​e ʻike koke i ke kauka!

Inā loaʻa iā ʻoe kekahi o kēia mau hōʻailona, ​​mai hoʻowahāwahā iā lākou. E ʻike koke i ke kauka.

• Nā loli o ka ʻike: ʻike pālua, ʻike pōwehiwehi, ʻike kolohe.
• Ka nalowale koke ʻana o ka ʻike.
• He manaʻo o kahi mea i paʻa i ka maka (inā paha e ʻike ʻia a ʻaʻole paha).
• ʻEha nui o ka maka.
• Ka hoʻokahe mau ʻana o nā maka (epiphora).
• ʻAʻole hiki ke nānā i ka mālamalama (photophobia).
• ʻUlaʻula a mumū paha o nā maka.
• He hahau i ka maka.
• He ʻeha i ʻike ʻia, kahi kahakaha, a i ʻole kahi ʻoki ma ka ʻili o ka maka.
