Ezibangela amehlo abanale, isigaba kwezifo kunye neendlela ngokuphatha

Cataract eye - yimeko apho ilens uba welifu, kwaye, ngenxa yokuba kubonakale olwaphula kwinqanaba eyahlukileyo.

Phakathi ezibangela isifo kunokwenzeka kwakhona ngokuba imeko embi, omninzi yityhefu ichiza indalo ityhefu, kwakunye nenyathelo yemisebe yelanga okanye radiation. Ngowe-90% amatyala cataract eyenzeke ngenxa wokwaluphala yendalo, ngokuba kunye yobudala kukho nokuguqulwa ye kwiproteni, eyinxenye ye lens.

Ngelishwa, cataract amehlo - sisifo vuhlayiseki, unyango elondoloza akunakwenzeka. Indlela kuphela phandle - utyando, apho ilens isusiwe ingqongwe, kwaye endaweni yayo ifakwe i se ngumntu.

Oku kuya kunceda ukubuyisela emehlweni nokuphucula umgangatho yesigulane yobomi.

Olunye uhlobo sifo awazalwa enaso cataract, ebangela of enokuba neengxaki pathways, isifo seswekile, okanye izifo ezosulelayo ukuba eziphilayo umzali ndazi apho ngexesha ekhulelwe yokukhulelwa. Unyango kuxhomekeke iqondo ukuntsonkotha sifo, ukuba ngaba kuphazamisana kunye nophuhliso wendalo womntwana, ungenelelo ngotyando iyafuneka. Nangona kunjalo, kwimeko esahlukileyo, xa buphazamisana ukuyilwa yaphula engundoqo umbono, isiphako kufuneka lupheliswe ngokukhawuleza kangangoko kunokwenzeka.

Xa umntu luphuhlisa cataract iliso, ibonakalise mpawu zilandelayo:

1. acuity Visual sinciphile.
2. Ngamanye amaxesha kukho nokuqiniswa ukubona.
3. Isigulane ubona izinto ngokucacileyo.
4. Umfundi uba ithinti emhlophe, angwevu okanye omthubi.
5. Ubuntununtunu liyancipha ukukhanya okanye ukunyuka.

Ngokuqhelekileyo, le sicatshulwa sichazwa ngokuthi ndikho noxilongo yintsimi lwembono, ithwalelwe ulawulo xi intraocular. Ugqirha kwakhona isebenzisa electrophysiological ultrasound zoviwo kwiretina nemithambo. Iziphumo zophando ukuvumela ugqirha ukuba anyule unyango okanye yotyando. Khumbula ukuba unyango endala akuthethi ukuphelisa esi sifo, kodwa ikuvumela kuphela ukuba isantya lwalo lokukhawulelana nophuhliso.

Isifo ukuba aqheleka kakhulu kubantu abadala - oku cataract iliso. Unyango isikakhulu yenziwa usebenzisa phacoemulsification cuke evumela betyale ilens ngokusebenzisa micro-liqatywe. Ixesha lokuqala inkqubo efanayo yasetyenziswa iminyaka engaphezu kwama-amathathu eyadlulayo. Namhlanje, kusetyenziswa 90% kuzo zonke iintengiselwano.

Khumbula ukuba uphando lwale mihla lubonise ukuba elide umguli kade ukusebenza, elinde nokwanda ngokupheleleyo seengxangxasi, ukuba kuya kuba nzima unyango ukulandela-up.

Cataract eye ikhula ukususela kwiminyaka emalunga-4 ukuya kwelesi-6 (12% yezigulane). Malunga nama-15% yabantu isigulane ukuba kancane kancane ngaphezu kweminyaka 10-15. Inkoliso yabantu, malunga nama-70%, ukuqhubela phambili kwesifo ukuya kwinqanaba kakhulu ithatha kwiminyaka emi-6 ukuya kweli-10. Kodwa kwegazi kungcono nangoku ku tirhisa ngaphandle kokulinda ukuba ilahleko ngokupheleleyo umbono.

baqamba Abantu abaninzi bakholelwa ukuba seengxangxasi - umboniso oluthi luqokelelane phezu olungaphandle iliso. Oku elahlekisayo ngenxa yokuba isigulane ubona yonke ngokungathi nge isigqubuthelo. Noko ke, umongo esi sifo kakhulu kakhulu kwaye nzulu ngakumbi, kuba iimpawu atshintshe kunye nohlobo lens. Kungenxa yoko le nto cataract akuxhomekekanga ziphathwe yi ukutya ekhethekileyo okanye amachaphaza. Bona, njengoko kubonisiwe ngaphambili, kungenza kancinane ukuqhubela phambili kwesifo, kodwa hayi ukunyanga nto.
