Amehlo cataract izimbangela, isigaba sesifo nezindlela zokwelapha

Cataract iso - isimo lapho i-lens kuba esinamafu, futhi, ngenxa manifest ukwephulwa of ezingeni ehlukene. Ukuthuthukiswa lesi sifo kungase kube ngenxa yokuba khona izifo ezithile (isib sikashukela), kodwa ngokuvamile kwenzeka ngaphansi kwethonya izici zangaphandle, njengoba umthetho, ukulimala kwamehlo. Phakathi kwezimbangela kungenzeka lesi sifo ubizwa nangokuthi emathonyeni amabi, kakhulu izidakamizwa ubuthi imvelo enobuthi, kanye isenzo emisebeni ultraviolet noma ngemisebe. Ngo-90% amacala cataract eba ngenxa yemvelo inqubo ukuguga, ngoba ngeminyaka kukhona denaturation amaprotheni, okuyinto ingxenye lens.

Ngeshwa, cataract iso - kuyinto isifo engelapheki, ukwelashwa ngoludala akunakwenzeka. Okuwukuphela kwendlela yokuphuma - ukuhlinzwa, lapho lens sisuswa empunga, futhi endaweni yayo ifakwe i lens yokufakelwa.

Lokhu kuzosiza aphinde abone futhi sithuthukise izinga lesiguli zokuphila.

Olunye uhlobo sifo azalwa naso cataract, izimbangela okungase iziyaluyalu umzimba, isifo sikashukela, noma izifo ezithathelwanayo lapho umzimba umzali evezwa ngesikhathi senyanga yokuqala sokukhulelwa. Ukwelashwa kuncike degree obulukhuni isifo, uma kungaphazamisi ukukhula okungokwemvelo ingane, kokungenela kuhlinzwa liyadingeka. Nokho, esimweni okuphambene, uma kuphazamisa kumiswa kokunikezwa kwe-central umbono, isici kumelwe iqedwe ngokushesha ngangokunokwenzeka.

Lapho umuntu eba ngeso cataract, sibonisa ukukholeka zimpawu ezilandelayo:

1. Visual acuity kuyehla.
2. Ngezinye izikhathi kukhona eqinisa ka myopia.
3. Isiguli ubona izinto ngokucacile.
4. Lo mfundi iba tint emhlophe, empunga noma ophuzi.
5. Ukuzwela ukukhanya liyancipha noma iyakhula.

Ngokuvamile, sicephu kuchazwe nokucija kanye kusebenta kwahulumende emkhakheni buka, eyenziwa intraocular ingcindezi control. Udokotela futhi isebenzisa luhlolo electrophysiological kanye ultrasound retina futhi izinzwa. Imiphumela inhlolovo ukuvumela udokotela lokuqoka izinhlobo zokwelashwa noma kuhlinzwa. Khumbula ukuthi ukwelashwa ngoludala alubuqedi isifo, kodwa ivumela kuphela ukubambezela ukuthuthukiswa yayo.

Isifo ovamile kakhulu kubantu abadala - lena iso cataract. Ukwelashwa ngokuvamile eyenziwa usebenzisa phacoemulsification ultrasonic okuvumela ukugxilisa lens ngokusebenzisa micro-imbobo. Isikhathi sokuqala inqubo efanayo yayisetshenziswa iminyaka engaphezu kuka amathathu edlule. Namuhla, isetshenziswa 90% yonke imisebenzi.

Khumbula ukuthi nocwaningo lwanamuhla luveza ukuthi eside isiguli uyaphuza operation, elinde nokuvuthwa egcwele ale nkinga, kwakuya kuba nzima kuyoba ukwelashwa ozolandela.

Cataract iso ukuvuthwa kusukela mayelana 4 kuya ku-6 iminyaka (12% eziguli). Cishe 15% labantu nesineke ke sanda kancane kancane eminyakeni engaphezu kwengu-10-15. Iningi labantu, ama-70%, ukuqhubekela phambili kwesifo kuya esigabeni ezinzima ihlala ezineminyaka engu-6 kuya ku-10. Kodwa ukuhlinzwa namanje kangcono ukuchitha ngaphandle kokulinda ukuba ukulahlekelwa okuphelele umbono.

Abantu abaningi ngephutha ikholelwa ukuthi lolu ngwengwezi - ifilimu kwakhiwa okuyinto ku ebusweni elingaphandle iso. Lena edukisayo ngenxa yokuthi isiguli ubona konke sengathi ngokusebenzisa umgubuzelo. Nokho, ngokuyisisekelo lesi sifo kakhulu ezimbi nakakhulu futhi ajulile, ngoba izindawo ukushintsha kanye nemvelo lens. Yingakho cataract akuyona ziphatha uhlobo olukhethekile lokudla noma amaconsi. Ababona, njengoba sibonile ngaphambili, kungenzeka kancane kancane ukuqhubeka kwesifo, kodwa abahlulekayo ukumphilisa ke.
