Iingcali sele zikhange iindlela zokukhusela i-cataract
Kulo lonke ihlabathi, i-cataracts iyona nto ibangela ubumpumputhe kunye nokulahleka kombono. EUnited States, abangaphezu kwama-50 ekhulwini kubo bonke abantu abaneminyaka engama-80 ubudala nangaphezulu baye bahlinzwa ngokunyanga, baxabisa i-$ 6.8 yezigidigidi ngonyaka. Utyando lweCataract kuphela yindlela ecacileyo yokuphatha i-cataract.
Ngenxa yobutyebi obunqongophe, abemi bamazwe asakhulayo bahlala bengakwazi ukufumana ukuhlinzwa ngecataract kwaye kufuneka bahlupheke ngokuqhubela phambili kwe-lens opacity eyenza kungabi nzima ukujonga phantsi kweemeko eziqhelekileyo kodwa kunzima kakhulu ukubona ebusuku okanye xa i-glare iyinkinga.
Ngamanye amazwi, kunzima kakhulu (kwaye kuyingozi) kubantu abanenkathazo yokuqhuba ebusuku.
Ngenxa yokungabikho kwe-cataract yokuhlinzwa kumazwe amaninzi kwihlabathi lonke, iingcali endle zide zifuna indlela yokukhusela i-cataracts. Kuqikelelwa ukuba ukufumanisa umlinganiselo wokukhusela ukulibazisa ukuqala kwe-cataracts kwiminyaka eyi-10 kunokubangela ukuhla kweepesenti ezingama-50 kwimithwalo ebonakalayo kunye noxinzelelo. Okwangoku, abaninzi abaphandi bamehlo bakholelwa ukuba ukusetyenziswa kwezidakamizwa ngeendlela ezithile kunokuthintela i-cataract.
I-hypothesis evunyelwe ngokubanzi malunga nokuphuhliswa kwe-cataracts ye-cataracts yokugxininisa kwe-pegs oxidative kunye nokungalingani kwe-osmotic njengesizathu. Ngokukodwa, i-radicals yamahhala yomsindo kunye neepilisi kwi-epithelium ngokugqithiseleyo i-lens kwaye ibangela ukuqhubela phambili kwe-opacity. Ama-antioxidants afana ne-vitamin C kunye ne-vitamin E ukuzinzisa ezi zinto zikhululekileyo, kwaye ngoko ke unqande ukutshabalalisa i-radicals.
Enyanisweni, siyazi ukuba i-lens ikhetha i-anti-oxidants njenge-suchaslutein, i-zeaxanthin, i-vitamin E, ne-vitamin C.
Ngokuqinisekileyo, izinto ngaphandle kokuxinzezeleka kweengcinezelo kunye nee-radicals zamahhala zidlala indima ekuphuhliseni i-cataracts eziquka:
- Ukukhanya kwe-UV
- utywala
- iswekile
- unyango lwehomoni
- ukutshaya
- ukunyanya
Ezi zinto zinokuthi zongezeleleke ngakumbi uxinzelelo lwe-oxidative kwaye zonakalise ukuba amehlo akho alondoloze umonakalo okanye ukulungiswa komonakalo.
Ukukhusela i-Cataract NeDiscoidant-Rich Rich
Iziphumo ezivela kwisiFundo seSweden ezipapashwe kwi- JAMA Ophthalmology ngo-2014 zibonisa ukuba ukunyuka kwe-cataracts kuncitshiswa phakathi kwabantu abadla rhoqo ukutya okunotyebileyo okunga-antioxidant njengemifuno enamagqabi, i-grains epheleleyo kunye nekhofi. Kule sifundo esikhulu sabasetyhini abaneminyaka eliphakathi kunye nabadala, izinto eziphazamisayo ezinjengokutshaya, isibonakaliso somzimba, imisebenzi yomzimba, kunye nezinga lemfundo liye zahlengahlengiswa, kwaye iziphumo zazingabalulekanga.
Ngenxa yokuba amanqanaba okwandisa ama-antioxidants ekudleni komntu ahlanganiswa nobuqhetseba obuncinci bokubunjwa kwe-cataract, uzama ukucinga ukuba izixhobo zokuncedisa i-antioxidant zinganciphisa umngcipheko we-cataract, nayo. Nangona kunjalo, uphando malunga nokuba i-antioxidant supplements isebenze ukukhusela i-cataracts iye yenze iziphumo ezingahambelaniyo.
Olunye uvavanyo olulandelelwano lwangoku nje olulandelwe kwiphephancwadi lwe- Ophthalmology ngo-2014 lubonisa ukuba ii-multivitamines ezizityebi kumxube we-antioxidant zinciphisa umngcipheko we-cataract-uhlobo lwe-cataract-nge-9 ekhulwini ngexesha le-11.2 iminyaka.
Olunye uphando lubonisa ukuba kulabo bathathi-nxaxheba abaphandle batya ukutya okunotye kwi-antioxidants, ukuxhaswa kwe-anti-oxidant ephezulu kakhulu kunokwandisa umngcipheko wesakhiwo se-cataract. Ukufumanisa oku kulandelwayo kubangelwa kwiingcamango ezingaphezulu kweemali, i-antioxidants ingakwazi ukuguqula i-pro-oxidants kwaye idale uxinzelelo lwe-oxidative.
Isizathu sokuba kutheni i-antioxidant supplements okanye i-multivitamin amalungiselelo awancinane ukukhusela i-cataracts mhlawumbi ihambelana nokuxakeka kwe-metabolism yabantu. Kuza kubekho namhlanje, akukho nxu lumano olunqongophele nolunokuthi lube nolunokuvelisa i-antioxidant-rich media environment inokutya okunempilo.
Ukongezelela, kukho i-antioxidants ezininzi ezingabonakaliyo, kwaye ezi antioxidants ezingaziwa zingadlala indima enkulu ekuthinteleni i-cataracts nezinye iintlobo zesifo.
ILizwi
Uphando lubonisa ukuba i-antioxidant supplements ayinanto yokuthintela umdlavuza kunye nesifo senhliziyo. Nangona kunjalo, ukutya okucebile kwimifuno enemiqabunga, iziqhamo ezinemibala kunye neminye imithombo ye-antioxidants iye yadibaniswa nomngcipheko wesifo somhlaza nesifo senhliziyo. Ngokufanayo, kanti ukutya okunokulinganisela okunomdla kwi-antioxidants kunokunceda ukukhutshwa kwe-cataract, ukusetyenziswa kwe-antioxidant yangoku kungenzi nto inokuthintela eso sifo. Ekugqibeleni, ukuba unethemba lokuphucula inzuzo yama-antioxidants, ukubethelwa kweyona ndlela yokutya kubaluleke kakhulu kukutya ii-antioxidants ngaphakathi kwimeko yokutya okunomsoco kwaye ugweme ukuthatha izongezelo ezinokuthi zenze izinto ezincinci kwaye zinokubangela ingozi.
