Chidule

Arcus senilis ndi theka la buluu wa imvi, yoyera, kapena wachikaso m'mphepete mwakunja kwa cornea yanu, gawo lakunja loyang'ana kutsogolo kwa diso lanu. Zimapangidwa ndi mafuta ndi mafuta.

Okalamba, arcus senilis ndiofala ndipo nthawi zambiri amayamba chifukwa cha ukalamba. Kwa achinyamata, atha kukhala okhudzana ndi kuchuluka kwama cholesterol.

Arcus senilis nthawi zina amatchedwa corneal arcus.

Zoyambitsa

Arcus senilis amayamba chifukwa cha madontho a mafuta (lipids) kunja kwa cornea yanu. Cholesterol ndi triglycerides ndi mitundu iwiri ya mafuta m'magazi anu. Zina mwa lipids m'magazi anu zimachokera ku zakudya zomwe mumadya, monga nyama ndi mkaka. Chiwindi chako chimatulutsa zotsalazo.

Chifukwa chakuti muli ndi mphete kuzungulira kornea yanu, sizitanthauza kuti muli ndi cholesterol yambiri. Arcus senilis ndiofala kwambiri anthu akamakalamba. Izi ndichifukwa choti mitsempha yamagazi m'maso mwanu imayamba kutseguka ndi ukalamba ndipo imalola cholesterol yambiri ndi mafuta ena kutayikira mu cornea.

Pafupifupi 60 peresenti ya anthu azaka zapakati pa 50 ndi 60 ali ndi vutoli. Atakwanitsa zaka 80, pafupifupi 100% ya anthu azipanga arc iyi mozungulira cornea yawo.

Arcus senilis amapezeka kwambiri mwa amuna kuposa akazi. Anthu aku Africa-America atha kukhala ndi vutoli kuposa anthu amitundu ina.

Mwa anthu ochepera zaka 40, arcus senilis nthawi zambiri amakhala chifukwa chobadwa nawo chomwe chimakulitsa cholesterol ndi triglyceride.

Nthawi zambiri, ana amabadwa ndi arcus senilis. Kwa achinyamata, vutoli nthawi zina limatchedwa arcus juvenilis.

Arcus senilis amathanso kuwoneka mwa anthu omwe ali ndi Schnyder central crystalline dystrophy. Mkhalidwe wosawerengekawu, wobadwa nawo umayambitsa makhiristo a cholesterol kuti aike pa diso.

Zizindikiro

Ngati muli ndi arcus senilis, mudzawona theka-loyera loyera kapena loyera kumapeto ndi kumunsi kwa cornea yanu. Theka-bwalo lidzakhala ndi malire akunja lakuthwa komanso malire amkati amkati. Mizere pamapeto pake imadzaza kuti ipange bwalo lathunthu kuzungulira Iris yanu, yomwe ndi gawo lakuda la diso lanu.

Mosakayikira simudzakhala ndi zisonyezo zina zilizonse. Bwalo lisakhudze masomphenya anu.

Njira zothandizira

Simusowa kuchiza vutoli. Komabe, dokotala wanu angakulimbikitseni kuti muyese kuchuluka kwanu.

Ngati simunakwanitse zaka 40 ndipo muli ndi arcus senilis, muyenera kuyezetsa magazi kuti muwone kuchuluka kwanu kwama cholesterol ndi lipid. Mutha kukhala pachiwopsezo chachikulu cha cholesterol komanso mitsempha yamagazi.

Dokotala wanu amatha kuchiza cholesterol yambiri m'njira zingapo. Mutha kuyamba ndikuyesera kusintha kwa moyo wanu, monga kuchita masewera olimbitsa thupi komanso kudya zakudya zopanda mafuta ambiri, mafuta osakaniza, ndi cholesterol.

Ngati zakudya ndi masewera olimbitsa thupi sizokwanira, mankhwala angapo angathandize kuchepetsa milingo yanu ya lipid:

• Mankhwala osokoneza bongo amachotsa chinthu chomwe chiwindi chanu chimagwiritsa ntchito kupanga cholesterol. Mankhwalawa amaphatikizapo atorvastatin (Lipitor), fluvastatin (Lescol), lovastatin (Altoprev), pravastatin (Pravachol), ndi rosuvastatin (Crestor).
• Mafuta a asidi omanga amakakamiza chiwindi chanu kuti chigwiritse ntchito cholesterol yambiri kuti apange zinthu zam'mimba zotchedwa bile acid. Izi zimasiya mafuta ochepa m'magazi mwanu. Mankhwalawa akuphatikizapo cholestyramine (Prevalite), colesevelam (Welchol), ndi colestipol (Colestid).
• Zoletsa mafuta m'thupi monga ezetimibe (Zetia) zimachepetsa mafuta m'thupi mwanu.

Mankhwala atha kugwiritsidwa ntchito kutsitsa milingo ya triglyceride:

• Mafinya amachepetsa kupanga lipids m'chiwindi chanu ndikuwonjezera kuchotsedwa kwa triglycerides m'magazi anu. Amaphatikizapo fenofibrate (Fenoglide, TriCor) ndi gemfibrozil (Lopid).
• Niacin amachepetsa kupanga lipids ndi chiwindi.

Arcus senilis ndi cholesterol yambiri

Chiyanjano pakati pa arcus senilis ndi cholesterol yachilendo mwa okalamba chakhala chovuta. ati vutoli limalumikizidwa ndi mavuto a cholesterol komanso matenda amtima mwa okalamba. kunena kuti arcus senilis ndichizindikiro cha ukalamba, ndipo sichizindikiro chazowopsa zamtima.

Arcus senilis ayamba asanakwanitse zaka 45, nthawi zambiri zimakhala chifukwa cha vuto lotchedwa hyperlipidemia ya banja. Mtundu wamtunduwu umadutsa kudzera m'mabanja. Anthu omwe ali ndi vutoli ali ndi cholesterol kapena triglycerides ochuluka modabwitsa m'magazi awo. Ali pachiwopsezo chachikulu cha matenda amtima.

Zovuta ndi zoopsa

Arcus senilis palokha sichimayambitsa mavuto, koma cholesterol chokwera kwambiri chomwe chimayambitsa anthu ena chitha kuwonjezera zoopsa za mtima.Mukakhala ndi matendawa musanathe zaka 40, mutha kukhala pachiwopsezo chachikulu cha matenda amitsempha yamtima kapena matenda amtima.

Chiwonetsero

Arcus senilis sayenera kukhudza masomphenya anu. Komabe, ngati muli nacho - makamaka ngati mukudziwika musanakwanitse zaka 40 - mutha kukhala pachiwopsezo chachikulu chodwala mtsempha wamagazi. Kuchepetsa cholesterol yanu ndi zakudya, masewera olimbitsa thupi, komanso mankhwala kumachepetsa matenda anu amtima.
