Ukusetyenziswa kwexesha elide kwe-Prednisone okanye ezinye i-Steroids Inokuthi ikhokele kwiCataracts
Imithi ye-Steroid, kuquka i- prednisone , isetyenziselwa ukunyanga isifo sesisu (IBD) . Esinye isiphumo se-prednisone esinokuthi senzeke ngamanqanaba aphezulu okanye ukusebenzisa ixesha elide kukuphuhliswa kwee-cataract.
Iingxaki ze-cataracts zicatshulwa njengemeko yabantu abadala. Nangona kunjalo, i-steroids inokubangela ukuba i-cataracts iphuhlise kubantu abancinci. Ngokungafani nemiphumo emibi, njengobuso "ukukhwabanisa," ukwandisa ukondla, ukukhula kweenwele kunye ne-acne, i-cataract ayiyi kulandela emva kokuba ikhosi ye-steroid iphelele.
Nangona kunjalo, ukuba umlinganiselo we-steroid uncitshisiwe okanye unqanyulwa, i-cataract esele ikhona ayinakufumana nayiphi na inkulu.
Iingxwaba zinenhlanhla zonyango. Akuyena wonke umntu ofuna i-steroid iya kuba neengxaki zentlungu. Le mpembelelo embi ye-steroid iyaziwa, nangona kunjalo, kwaye nabani na abathatha la mayeza kufuneka babone ugqirha weziliso rhoqo.
Sibanzi
Kulo lonke uluntu lwaseMerika, kulinganiselwa ukuba abantu abangama-31% abaneminyaka engama-65 no-74 ubudala, kunye nama-53% abantu abangaphezu kweminyaka engama-75 ubudala, ubuncinane bodwa. Iingcongcingo zengqungquthela zingabakho kwiintsana (ngezinga le-10 000 ngonyaka), kodwa ngokubanzi zibangelwa sisifo, ukusetyenziswa kakubi kweziyobisi okanye utywala ngexesha lokukhulelwa.
Emva kokukhanya kudlulela kumfundi welihlo, lidlula i-lens, equkwe ngokuyinhloko yamanzi kunye namaprotheni. I-lens isebenza kakhulu njengekhamera, igxininise ukukhanya kwi-retina.
I-lens yelihlo lakho inokutshintsha imeko ukugxila kwizinto ezisondele okanye ezikude. Ngethuba lexesha eliqhelekileyo lokuguga, ezinye zeeprotheyini kwi-lens zingadibanisa kunye, kubangele indawo yecala-cataract. Ummandla uya kuba mkhulu kwaye ube nexesha elingaphezu kwexesha, ulungele i-lensi kwaye wenze kube nzima ukubona.
Iintlobo
Kukho iintlobo ezintathu ze-cataract : i-nyukliya, i-cortical, kunye ne-post-subcapsular. I-Prednisone, mhlawumbi ngomlomo okanye kwinqabana lamehlo, lingabangela i-cataract posterior subattsular.
- Nyukliya: Olu hlobo lwe-cataract lukhula ngokukhawuleza, luqhelekile kubantu abadala, kwaye lunikeza iliso ity yellow.
- I-Cortical: Olu hlobo lwe-cataract luqhelekile kubantu abanesifo sikashukela. Iifom ze-cataract kwi-lens cortex, kwaye ekugqibeleni iqhubekela phambili njengezithethi kwivili.
- I-post subcapsular: Olu hlobo lwe-cataract lunokubangelwa ngamanani aphezulu okanye ukusebenzisa ixesha elide le-prednisone, ubude obuphezulu , kunye ne-retinitis pigmentosa. Olu hlobo lwama-cataract kwi-back lens, kwaye iimpawu zivame ukukhula ngokukhawuleza (kwiinyanga, kunokuba iminyaka). Njengoko ukukhanya kudlula kwinqanaba le-lens kunye ne-cataract, ihlakazekile kunokugxila. Umntu onesifo sengqondo se-postcapusular subcapsular yangaphambili angenenkxalabo yokubona izinto ezikufutshane.
Iimpawu
Izibonakaliso zentlungu zibandakanya:
- Umbono ogqabileyo
- Imibala (ngokukodwa eluhlaza okwesibhakabhaka) ibonakala iphelile
- Ubunzima bubona kumagumbi adibeneyo okanye adibeneyo
- Umbono ombini
- Ifilimu ngaphezulu kombono (okufana nokujonga nge windshield engcolileyo)
- Ukutshintsha kwimiyalelo yesigu
- Ukunyuka kwenyameko
- Ukubona ii-halos zijikeleze izibane
- Umbono wobusuku obuncitshisiwe
Izinto zobungozi
Ukusetyenziswa kwe-prednisone, elawulwa kwimiqathango ephezulu okanye ixesha elide elide, yinto engozi yobungozi. Nangona kunjalo, kukho ezinye izinto ezinobungozi, kubandakanywa neminyaka yobudala, ukuhlinzwa kwangaphambili kweso okanye ukuxhatshazwa, izimo ezingapheliyo kunye nemithi ethile.
Imiqathango engapheliyo enomngcipheko weengxaki zengxaki:
- Sikashukela
- Down syndrome
- Galactosemia
- I-rheumatoid arthritis
- I-muscular dystrophy
- I-myotonic dystrophy
- Retinitis pigmentosa
- Uveitis
- Isifo sikaWilson
Amachiza anokunyusa umngcipheko we-cataracts afaka:
- Amiodarone (i-antiarrhythmic)
- I-chlorpromazine (inzala)
- I-Lovastatin (i-cholesterol-downing drug)
- I-Phenytoin (i-antiseizure)
Akukho mayeza ayaziwa ukukhusela i-cataracts. Nangona kunjalo, kucingelwa ukuba ukutya okuphezulu kuma-antioxidants (i-beta-carotene, i-vitamin C, ne-vitamin E) kunokunceda ukukhusela i-cataracts, kunye nezinye izimo zempilo. Ukukhanya kwe-ultraviolet yinto eyaziwayo yengozi; ukugqoka izibuko zelanga okanye isitya esinomthi wokunciphisa ukutyhila. Ukukhathazeka kwamehlo kuyinkalo yobungozi; bembathe iingubo zokukhusela xa bebandakanyeka kwimisebenzi apho ukulimala kwamehlo kunokwenzeka khona.
Unyango
Kwimigangatho yokuqala ye-cataract, amehlo angathuthukiswa ngokusebenzisa ukukhanya kwamaglasi, ukukhanyisa okufanelekileyo kunye ne-lens magnifying for reading or other work close. Nangona kunjalo, ukuba i-cataract iqhubekela phambili kwindawo apho imisebenzi yemihla ngemihla iba nzima, ukuhlinzwa kungadingeka. Ngethamsanqa, ukuhlinzwa ngonyango kuyinto eqhelekileyo kwaye ikhuselekile, kwaye ezininzi izigulana zibika ukuphucula amehlo kunye nomgangatho wobomi emva koko.
Kukho iintlobo ezimbini ezahlukeneyo zokuhlinzwa: i- phacoemulsification kunye ne- extracapsular . Xa kutyunjwa, iprobefu encinane ephuma kumagagasi e-ultrasound efakwe kwiso ngephi. Amagagasi e-ultrasound enza ukuba i-cataract iqhekeke, ibe ilandelwa kude kwiso.
Ngophenyo lwe-cataract extracapsular, i-lens ene-cataract isuswe kwiso kwaye ithathelwe indawo yelensi yokufakelwa kwe-intraocular lens. I-lens yokufakelwa ibonakala kwaye ivakalelwa ngokuqhelekileyo, nangona ayikwazi ukuguqula umumo njengeliso lendalo. Abantu abane-lens intraocular bayakufuna iiglasi zokufunda okanye ukuvala umsebenzi.
