Kushandiswa Kwenguva Yakare KwePrednisone Kana Dzimwe Steroidyi Inogona Kutungamira KuCataracts
Steroid mishonga, kusanganisira prednisone , inowanzoshandiswa kurapa chirwere chinoputika (IBD) . Chimwe chikamu chinonzi prenisone side chinogona kuitika nemisero yakakura kana kushandiswa kwenguva refu ndekukudziridzwa kwehutachiona.
Mafungiro anowanzofungidzirwa semamiriro evanhu vakwegura. Zvisinei, steroids inogona kukonzera nharo kukura muvanhu vaduku. Kusiyana nedzimwe migumisiro, zvakadai sechiso che "mwedzi," kuwedzera kudya, nyuchi kukura, uye mazino, cataract haingarambi mushure mokunge chirwere che steroid chapera.
Zvisinei, kana steroid inotapudzwa kana kuderedzwa, chirwere chekare chinogona kunge chisingawani chero chikuru.
Dambudziko iri rinotyisa zvikuru rinoporesa. Haasi munhu wose anoda steroid anozoita mhuka. Izvi zvinokanganisa steroids inonyatsozivikanwa, zvakadaro, uye chero munhu anotora mishonga iyi anofanira kuona chiremba weziso nguva dzose.
Overview
Muhuwandu huwandu hweUnited States, inofungidzirwa kuti 31% yevanhu vari pakati pemakore makumi matanhatu nemakumi matanhatu nemazana manomwe, uye 53% yevanhu vanopfuura makore makumi manomwe, vane imwe cataract imwechete. Kukanganiswa kwekemukari kunogona kuitika muzvitsva (pamwero we10 000 pagore), asi kazhinji zvinokonzerwa nehutachiona, kana kushandisa zvinodhaka kana doro panguva yekuzvitakura.
Mushure mokunge chiedza chichipfuura nomudzidzi weziso, inopfuura napamusoro pe lens, iyo inosanganisira kunyanya mvura uye mapuroteni. Iyo lens inoshanda zvakadai sekamera, ichiisa chiedza ichocho mu retina.
Ikopa reziso rako rinogona kuchinja mamiriro ekuisa pfungwa pazvinhu zviri pedyo kana kure. Munguva yehutano hwekukwegura, mamwe mapuroteni ari mu-lens anogona kubatana pamwe chete, zvichiita nzvimbo yekunaka - cataract. Nharaunda yacho ichava yakakura uye yakawanda kupfuura nguva, ichivhara lens uye ichiita kuti zvive nyore kuona.
Aina
Kune mhando mitatu yecataract : nuclear, cortical, uye posterior subcapsular. Prednisone, kana mumuromo kana mumadonhwe eziso, inogona kukonzera posterior subcapsular cataracts.
- Nyukliya: Iri rudzi rwekataract rinokura zvishoma nezvishoma, rinonyanya kuonekwa kune vanhu vakwegura, uye rinopa ziso rhizha tinge.
- Cortical: Mhando iyi ye cataract inowanzoonekwa kuvanhu vane chirwere cheshuga. A cortical cataract inowanikwa mu-lens cortex, uye pakupedzisira inowedzera kunze semapiro pairi.
- Posterior subcapsular: Mhando iyi ye cataract inogona kukonzerwa nepamusoro-dhira kana kushandiswa kwenguva refu kwe prednisone, kutarisa zvakanyanya, uye retinitis pigmentosa. Iko rudzi rwekataracita maitiro ari kumashure kwe lens, uye zviratidzo zvinowanzokurumidza kukurumidza (mumwedzi, pane makore). Sezvo chiedza chichipfuura nomugove wekunze kwe lens ne cataract, inopararira pane kungotarisa. Munhu ane kambani posterior subcapsular cataract angave ane dambudziko rakawanda kuona zvinhu zvitsva.
Zviratidzo
Zviratidzo zvehutu zvinosanganisira:
- Blurry chiratidzo
- Makara (kunyanya bhuruu) anooneka akaoma
- Dambudziko kuona mumakamuri akajeka kana akadzikama
- Chiono chechipiri
- Firimu pamusoro pemaonero (zvakafanana nekutarisa mumhepo ine tsvina)
- Kakawanda kemaziso echechi maziso anochinja
- Kuwedzera kwekuswedera pedyo
- Kuona halos pedo nemwenje
- Yakapedzisira kuonekwa usiku
Risk Factors
Kushandiswa kwet prednisone, inoshandiswa pamitambo yakakwirira kana kwenguva yakareba, inokonzerwa nehutachiona. Kunyange zvakadaro, pane zvimwe zvimwe zvinokonzera njodzi, kusanganisira makore, chiratidzo chekuona kwemaziso kana kushungurudzika, zvirwere zvisingaperi, nemimwe mishonga.
Mamiriro ezvinhu akapera anotakura mungozi yehutachiona:
- Chirwere cheshuga
- Down syndrome
- Galactosemia
- Juvenile rheumatoid arthritis
- Muscular dystrophy
- Myotonic dystrophy
- Retinitis pigmentosa
- Uveitis
- Chirwere cheWilson
Mishonga inogona kuwedzera mungozi yehutachiwana inosanganisira:
- Amiodarone (antiarrhythmic)
- Chlorpromazine (sedative)
- Lovastatin (cholesterol-downing drug)
- Phenytoin (antiseizure)
Hapana mishonga inonyatsozivikanwa kuchengetedza cataracts. Zvisinei, zvinofungidzirwa kuti kudya kwakanyanya mu antioxidants (beta-carotene, vitamin C, uye vitamini E) kunogona kubatsira kudzivirira kukanganisa, pamwe nezvimwe zvirwere zvehutano. Ultraviolet chiedza inozivikanwa pangozi; kupfeka magirazi egirasi kana hovha ine brim kuitira kuderedza kusvitsa. Kushungurudzika kweziso kunowedzerawo ngozi; kupfeka kuchengetedza maziso kana uchiita mabasa apo kukuvara kweziso kunogona.
Mishonga
Muchikamu chekutanga checataract, maziso anogona kuvandudzwa kuburikidza nekushandiswa kwegirasi remaziso, chiedza chakafanira, uye lenzi rinokudza pakuverenga kana rimwe basa repedyo. Zvisinei, kana cataract ichienda kune imwe nzvimbo iyo mabasa ezuva nezuva anooma, kuvhiyiwa kunogona kudiwa. Nenzira yakanaka, chirwere chechipatara chinowanzochengeteka, uye vazhinji varwere vanotaura vachivandudza maziso uye hupenyu hwehupenyu shure.
Kune marudzi maviri akasiyana-siyana ekuvhiya kwecataract: phacoemulsification uye extracapsular . Mukuvhiya kwepacemulsification, purojekiti shoma inobvisa mazai e ultrasound inowanikwa muziso kuburikidza nekukanganiswa. Iyo mazai e-ultrasound anoita kuti chirwere chinoputika zvidimbu, izvo zvino zvinotorwa kubva paziso.
Mu extracapsular chirwere checataract, lensi ine cataract inobviswa kubva muziso uye inotsiviwa neinteria yechipraca intensocular. Iko lenzi yekugadzira rinotarisa uye rinonzwa rakanaka, kunyange risingagoni kuchinja maitiro akaita sendima yemhuka. Vanhu vane lens intraocular vachada magirazi emaziso ekuverenga kana kuswedera.
