I-Cataract yisona sifo esiqhelekileyo esibonakaliswe ukuguga. Ngexesha lokubunjwa kwe-cataracts, iprotheni ifakwe kwi-lens (khumbula ukuba i-lens yincinane "iglasi yokukhulisa" malunga ne-12 mm ububanzi kunye no-5 mm ubukhulu emva kwe-iris engxenyeni yangaphambili yeliso.) Sidinga ilensi yokujolisa okongeziweyo komfanekiso kwi-retina. Ukwabela i-glacoma yesibalo sokuqala, yesibini kunye nesibini. Iimpawu zesi sifo zonyuka uxinzelelo lwe-intraocular, ukunciphisa intsimi ebonakalayo, i-atrophy ye-optic nerve, ukuphazamiseka kwe-outflow nokunyuka kwe-intraocular fluid. Izigulane ezininzi zikhalaza iintloko. Iinkqubo ezenzileyo kwi-retina kunye ne-choroid (i-dystrophy ye-retina) kubangelwa ukunyuka kwemithambo yegazi kwindawo ephakathi. Ukutya kwe-retina kummandla ojongene nokujonga ukukhanya kuphazamiseka. I-retin dysstrophy ingakhokelela ekulahlekelweni ngokupheleleyo kombono.
Ukubona kakuhle kukuqinisekisile impilo, ngoko ke, ukugcina imisebenzi ebonakalayo, abantu bayayincedo imifuno, iziqhamo, intlanzi. Iikaroti, iklabishi, isipinashi, ii-oranges (umthombo we-antioxidants) kunye neentlanzi ezinamafutha (umthombo we-omega-3 fatty acids) yindlela yokulungisa izifo zamehlo. I-Journal ye-American Medical Association yenze isifundo. Kwabakho abo bathatha iimveliso ezizityebi kwi-beta-carotene, i-zinc, iivithamini C no-E, izinga lokuphuhliswa kwe-retinal dysstrophy lehle ngo-35%. Ukusetyenziswa kweentlanzi ezinamafutha kanye ngeveki kunciphisa izinga lokuphuhliswa kwe-retinal nge-70%. Kwi-American Journal of Epidemiology, ingxelo-yokubonisana kwezigulane ezingama-4000 yashicilelwe: phakathi kwabasetyhini abadla rhoqo i-tuna kunye ne-salum, umngcipheko we-cataracts wehle ngo-15%.
Ukujonga amehlo
Ukutya okuMhlophe kunye nokutya kweswekile okunomxholo ophezulu we-glycemia (izinga leshukela legazi) negalelo ekuphuhliseni i-dysstrophy ye-retinal. Iimveliso ezinjalo zinciphisa i-metabolism, enokubangela, ngokutsho kwezenzululwazi, ukuphuhliswa kwezifo zeso. Ngokuphambene noko, ukujonga kakuhle - isibambiso sempilo sinomdla ekusebenziseni iivithamini, imifuno kunye neziqhamo.
Antioxidants
Ekulweni nezifo zamehlo, indima yama-antioxidants, "adibanisa" iiseli ezonakaliswe ukukhanya kwelanga, inkulu. Ilanga elisebenzayo likhuthaza ukuphuhliswa kwama-radicals kumahhala egazini, okonakalisa iimitha zegazi ezincinci. I-Antioxidants iyanciphisa i-radicals yamahhala.
Uqeqesho lwamaziko
Imisebenzi yezemidlalo, ukulawula ubunzima obuninzi kunciphise izinga lokuphuhliswa kwe-retinal dystrophy. Ukunyuka kwiindawo zokuzivocavoca kwanciphisa ukuphuhliswa kweeklasi ze-glaucoma kunceda ukunciphisa uxinzelelo lwe-intraocular. Nangona uzalwe ngesifo sikashukela, imidlalo iya kukunceda uthobe izifo ezikhankanywe ngasentla. Kubantu, isalathisi sesiswini somzimba (i-index ye-Kettle) ingaphezulu kweeyunithi ezingama-25, ingozi yokuphuhlisa i-dystrophy ye-retinal iphindwe kabini kweso sineziqhelo. Yiya kwindawo yokuzivocavoca okungenani kathathu ngeveki, kwaye izinga lokuphuhliswa kwezifo zamehlo liya kuhla nge-25%. Iingcali zenzululwazi zikholelwa ukuba zonke izifo zengxubevange, kungekudala okanye kamva, zikhokelela kwi-dysstrophic retinal.
Ukupheliswa ngokupheleleyo kokutshaya
Ukubhema ngenye yezimbangela ezibalulekileyo zokutshatyalaliswa kwe-dystrophy. Iifomsi eziqulethwe kwi-cigarettes zinokunciphisa ukuhamba kwegazi kwaye zikhokelela ekuphuhlisweni kwamacengezi egazi ngaphakathi kwamehlo e-eye, kwaye zibonisa ama-radicals amahhala. Iimveliso zamakhemikhali eziqulethwe kumsiya zonakalisa iinqanawa zokubuyisela, zinciphisa. Kwaye oku kuholele ekutheni i-dysstrophic retinal.
Ukunyamekela ngononophelo lwama-lens
Naluphina uhlalutyo lwamafayili akho oqhagamshelwano lukhokelela ekusasazeni kweebhaktheriya, eziwela kwisakhiwo esibucayi kwiso, zingonakalisa i-cornea kwaye ibangele isifo sayo. I-fungus ibhubhisa izicubu ze-corneal, ezibangela ukuvutha kwayo, okunzima kakhulu ukuyilawula. Inkqubo yokuvutha ingakhokelela ekulahlekelweni kombono. Ukukhusela amehlo akho, soloko uhlamba izandla ngaphambi kokuba ufake iilensi. Soloko usebenzisa i-lens liquid cleaning. Ungasebenzisi i-lens for lenses ezide ziphelile ngobomi bokugcina bokugcina.
Ukubonisana rhoqo ne-ophthalmologist
Ukususela kwiminyaka engama-35 ubudala, jonga amehlo akho nge-ophthalmologist yonke iminyaka emi-2-4 (emva kweminyaka engama-65 - amaxesha amabini ngonyaka). Ugqirha unyanzelekile ukuba ahlolisise i-fundus kunye noxinzelelo, acwangcise ukulungiswa okuchanekileyo kwaye abhale iiglasi (ukuba umbono ubonakele, kuyimfuneko ukufaka iiglasi). Namela ugqirha, nokuba ubani ohlala kwintsapho yakho ahlupheke ngenxa yezifo zamehlo, ingakumbi i-glaucoma, ingaba kukho intsapho yabaswekile. Konke oku kwenziwa ukwenzela ukuthintela ingozi yokuqala yezifo zamehlo.
Sebenzisa amaconsi asehlo
Akukho mzekelo ungayishiyi iliso lehlohlo ugqirha elimiselayo xa kunesifo sengqondo okanye ukusuleleka kweso. Nangona kunjalo, ukuba umnqweno wakho ukunyanzela amehlo akho omileyo okanye "uhlaziye" emva kobusuku bokulala, sebenzisa amaconsi asekelwe kwinto yokwakheka "yendalo". Gwema ukulawulwa kwamanyango okujoliswe kukukhupha amehlo obomvu. Bakhulula ubomvu ixesha elifutshane ngenxa yokunciphisa imithwalo yegazi. Ngokukhawuleza ukuba umphumo weehlahla ziphelile, izitya ziya kwandisa kwaye amehlo aya kuvuka kwakhona.
Iimvaneli
Ukugqoka izibuko zelanga nakwiimozulu zenkwenkwezi zikhuseleke kakhulu kwizifo zamehlo. Kwaye ngokukhawuleza ulandela lo mgaqo, bhetele. Ngokubhenca amehlo akho ukukhanya kwelanga, ukuphindaphinda kathathu umngcipheko we-cataracts xa kuthelekiswa nalabo basebenzisa izibuko zelanga. Xa uthenga, qaphela ukuba bakukhusela kwiifom zombane ezifutshane kunye namaxesha amade (ii-UV zemibala ye-A kunye neB). Imibala ye-spectrum Ingena ngokukhawuleza kwesikhumba, iyanciphisa ukunyusa, iyanciphisa ukuxakaniseka kwaye ivuselele imbonakalo yobunzima.
