La cataract he pilikia o ka hihio hiki ke hana i ka wā e nalowale ai ka lens, kēia lens oval liʻiliʻi ma hope o ka haumāna mäliko.

a hiki aku i ka ʻomiLomini lilo i ao, hiki i nā kukuna māmā i ka retina me ka maikaʻi ʻole, e wehewehe ana i ke kumu o ka popopo ka hihio. Ua koho ʻia ka huaʻōlelo cataract e wehewehe i kēia manaʻo o ka nānā ʻana i kahi wailele (mai ka Latin cataract, ʻo ia hoʻi ka wailele). Hana like ka lens me ka lens o ka pahupaʻikiʻi kiʻi: e kālele i ke kiʻi e like me ka mamao mai ka mea i ʻike ʻia. Hana ka lens i kēia ma ka hoʻololi ʻana i kona curvature.

ʻO ka pinepine, hana mālie nā cataracts, me ka kūnewa. I ka wā lōʻihi, hoʻololi ke ʻano o ka lens. ʻAʻole maopopo iā mākou ke kumu, akā ʻo ke kuhiakau nui ke hoʻololi ʻia nā protein lens e nā radical manuahi, nā mea i hana maoli ʻia e ke kino a kōkua i ka ʻelemakule. Hoʻokaʻawale ʻia nā radical manuahi e nā antioxidants, loaʻa nui mai nā huaʻai a me nā mea kanu.

Hōʻike ka cataract i ka 3^e kumu o makapo ma Kanada. ʻO nā kumu nui o ka makapō - ka macular degeneration, glaucoma a me ka cataracts - hiki pinepine i ka wā ʻelemakule.

ʻO wai ka mea i hoʻopili ʻia?

mai ka 65 makahiki, ka hapa nui o na kanaka i ka mua cataract. ʻAʻole hiki i ka opacification o ka lens ke hōʻeha i ka ʻike inā hana ʻia ia ma nā ʻaoʻao peripheral o ka lens.

Ma hope o ka makahiki o 75 makahiki, ʻelua hapakolu o ka poʻe ʻAmelika i loaʻa i nā maʻi cataract i hiki ke hoʻopilikia i kā lākou ʻike. ʻO ka nalowale hihiʻo ʻoi aku ka ʻino me ka makahiki. Hoʻopilikia ka Cataract i nā kāne a me nā wahine.

He nui nā ʻano o ka cataracts, ʻo ia nā mea nui.

• Senile cataract. Loaʻa ka hapa nui o nā cataracts i ka poʻe ʻelemakule. ʻO ke kaʻina hana maʻamau e hiki ke alakaʻi i ka paʻakikī a me ke ao o ka lens. ʻOi aku ka hopena o ka maʻi cataracts pili makahiki i kekahi maka ma mua o kekahi.
• ʻĀpana lua. ʻO kekahi mau maʻi (ʻoi aku ka maʻi diabetes, inā maikaʻi ʻole ka mālama ʻia ʻana), ka lawe ʻana i kekahi mau lāʻau lapaʻau (e laʻa, cortisone i lawe ʻia e ka waha), a i ʻole ka ʻike ʻana i nā haʻahaʻa kiʻekiʻe o ka radiation ke kumu o ka maʻi cataracts. Eia hou, ua loaʻa iā ʻoe kekahi pilikia o ka maka (e like me ka myopia kiʻekiʻe, glaucoma a i ʻole retinal detachment) ʻoi aku ka pilikia o ka maʻi cataracts.
• ʻO ka maʻi ʻehaʻeha. Loaʻa ia ma muli o ka ʻeha o ka maka e hōʻino ai i ka lens: he pā, ʻoki ʻia, ʻike ʻia i ka wela wela, kahi wela kemika, etc.
• Cataracts i na keiki. Hiki ke hoʻomaka ka maʻi maʻi mai ka hānau ʻana, akā kakaikahi. Hiki ke hele pū me kahi maʻi hānau (no ka laʻana, trisomy 21) a i ʻole he maʻi lele mai ka makuahine i hoʻouna ʻia i ka pēpē i ka wā hāpai, e like me ka rubella, toxoplasmosis, genital herpes a syphilis.

Evolution

Ke 'ʻike kālā hāʻule i kahi o ka hoʻopaʻa ʻana i nā hana o kēlā me kēia lā, he hōʻailona paha kēia o ka cataracts. ʻO ka maʻamau, hele mālie kēia nalowale o ka ʻike, i nā makahiki he nui. Eia naʻe, i kekahi manawa hiki koke mai ia (i loko o kekahi mau mahina).

Ke piʻi aʻe ka maʻi cataract, ka haumana ʻaʻole ʻike hou ʻia ka ʻeleʻele, akā hina a i ʻole a keʻokeʻo waiū. Ma kahi pae holomua, hiki ke kaupalena ʻia ka ʻike i ka ʻike o ka mālamalama.

Āhea e kūkākūkā ai?

La cataract ʻike pinepine ʻia i ka wā a maka maka na ke kanaka ophthalmologist. ʻO ka hoʻololi ʻana i ka maikaʻi o ka ʻike maka pono e ʻike i kahi ophthalmologist.
