Ukubuka konke
I-Nuclear sclerosis ibhekisa ebumnyameni, ukuqina, nokuphuzi kwesifunda esiphakathi kwelensi esweni elibizwa ngokuthi i-nucleus.
I-Nuclear sclerosis ivame kakhulu kubantu. Kungenzeka futhi ezinja, amakati, namahhashi. Imvamisa kukhula ku. Lezi zinguquko ziyingxenye yenqubo yokuguga kweso.
Uma i-sclerosis ne-clouding kunzima ngokwanele, kubizwa ngokuthi yi-cataract yenuzi. Ngombono othintwe yi-cataract, ukulungiswa okujwayelekile ukuhlinzwa ukususa ilensi enamafu bese uyifaka esikhundleni selensi yokufakelwa.
Ziyini izimpawu?
I-nuclear sclerosis ehlobene nobudala iguqula ukugxila kwelensi ukubona eduze. Ukufiphala eduze kombono obangelwa yiminyaka kubizwa nangokuthi i-presbyopia. Umbono oseduze usetshenziselwa imisebenzi efana nokufunda, ukusebenza kwikhompyutha, noma ukunitha. Lokhu kungalungiswa kalula ngezibuko zokufunda ezinomuthi ofanele wokulungisa umphumela wokwenza lukhuni ilensi.
Ngokuphambene nalokho, i-cataract yenuzi ithinta umbono webanga ngaphezu kokubona eduze. Omunye umphumela we-cataract ukuthi angenza ukushayela kube nzima kakhulu. Uma une-cataract yenuzi, ungaba nalezi zimpawu ezilandelayo:
- kunzima ukubona izimpawu zomgwaqo, izimoto, umgwaqo, nabahamba ngezinyawo ngenkathi ushayela
- izinto ezibonakala zifiphele futhi imibala yaphela
- kunzima ukubona izinto ekukhanyeni okukhanyayo
- uhlangabezana nokukhanya okukhulu kusuka emalambini ebusuku
Umbono wakho nawo ungabonakala ubuthuntu noma ufiphele, noma kwesinye isikhathi ungahle ube nombono ophindwe kabili.
Kungani kwenzeka?
Izinto ezakha ilensi yeso zakhiwa amaprotheni namanzi. Imicu yento yelensi ihlelwe ngephethini ehleleke kakhulu, evumela ukukhanya kudlule.
Njengoba sikhula, imicu emisha yakha emaphethelweni elensi. Lokhu kuphusha izinto zelensi ezindala zibheke maphakathi nelensi, okwenza isikhungo sibe namandla futhi sibe mnyama. Ilensi nayo ingathatha umbala ophuzi.
Uma i-sclerosis yenuzi inzima ngokwanele, ibizwa ngokuthi yi-cataract yenuzi. Amaprotheni akulensi aqala ukuhlangana, asakaze ukukhanya esikhundleni sokukuvumela kudlule. I-cataract idala konke ukungaboni emhlabeni, kanti i-cataract yohlobo lwenuzi luhlobo oluvame kakhulu.
Ama-cataract angaba yingxenye ejwayelekile yokuguga, kepha angenzeka futhi ngaphambi kwesikhathi ngenxa yokuvezwa ukukhanya kwe-UV, ukubhema nokusetshenziswa kwe-steroid. Isifo sikashukela naso siyingozi engozini yokuphathwa yiso.
Kutholakala kanjani?
Udokotela wamehlo, udokotela wamehlo, noma udokotela wamehlo angahlola i-nuclear sclerosis kanye ne-cataract ngokuhlola iso ngokucophelela. Amafu nokuphuzi kwe-nucleus kungakhonjwa ngesikhathi sokuhlolwa kwamehlo okujwayelekile. Yingakho kubalulekile ukuthi uhlolwe unyaka nonyaka, noma ngabe awunazo izinkinga ezibonakalayo ngombono wakho.
Ukuhlolwa okuningana kuyasiza ekutholeni i-nuclear sclerosis kanye ne-cataract yenuzi:
- Ukuhlolwa kwamehlo okukhanyisiwe. Ngesikhathi sokuhlolwa, udokotela ubeka amaconsi emehlweni ukwenza abafundi bavuleke (bavuleke). Lokho kwenza ukuthi sikwazi ukubona ngeso lens nangaphakathi kweso, kufaka phakathi i-retina ezwela ukukhanya ngemuva kweso.
- Sika isibani noma ukuhlolwa kwe-biomicroscope. Kulesi sivivinyo, udokotela ukhanyisa umsebe omncane wokukhanya esweni ukuze akwazi ukuhlola ngokucophelela ilensi, ingxenye emhlophe yeso, i-cornea, nezinye izakhiwo emehlweni.
- Umbhalo we-red reflex. Udokotela uphonsa ukukhanya ebusweni beso bese esebenzisa umshini wokukhulisa obizwa nge-ophthalmoscope ukubheka ukukhanya. Ngamehlo enempilo, ukubonakaliswa kungumbala obomvu ogqamile futhi kubukeka kufana emehlweni womabili.
Ukwelapha lesi simo
I-sclerosis yenuzi ehlobene nobudala ayidingi ukuhlinzwa, izibuko ezinhle nje zokufunda. Uma ukuqina nokuba mnyama kuphenduka inkalakatha yenuzi, umbono wakho nesimo sakho kuzoba kubi ngokuhamba kwesikhathi. Kepha kungahle kube yiminyaka ngaphambi kokuthi udinge ukushintshwa kwamalensi.
Ungakwazi ukubambezela ukuhlinzwa kwe-cataract yenukliya uma umbono wakho ungathinteki ngokulandela lezi zeluleko:
- Gcina imishanguzo yakho yesibuko seso isesikhathini.
- Gwema ukushayela ebusuku.
- Sebenzisa ukukhanyisa okuqinile ukuze ufunde.
- Gqoka izibuko zelanga zokulwa nokukhanya.
- Sebenzisa ingilazi yokukhulisa ukusiza ngokufunda.
Izinkinga ezinkulu zokuhlinzwa kwe-cataract akuvamile. Uma kwenzeka izinkinga, zingaholela ekulahlekelweni kombono. Izinkinga zingafaka:
- ukutheleleka
- ukuvuvukala ngaphakathi kweso
- Ukuma okungafanele kwelensi yokufakelwa ngesikhathi sokuhlinzwa
- ilensi yokufakelwa eshintsha isikhundla
- ithimba le-retina elivela ngemuva kweso
Kwabanye abantu, iphakethe lesicubu esweni eligcina ilensi entsha endaweni (i-posterior capsule) lingaba namafu liphazamise umbono wakho futhi ngemuva kokuhlinzwa kwe-cataract. Udokotela wakho angakulungisa lokhu ngokusebenzisa i-laser ukususa ubuwula. Lokhu kuvumela ukukhanya ukuthi kudlule kulensi entsha kungaphazanyiswa.
Umbono we-nuclear sclerosis
Izinguquko ezihlobene nobudala ezifana ne-nuclear sclerosis azidingi izidakamizwa noma ukuhlinzwa. Ukuqina kwelensi kungaphazamisa ukubona, kepha lokhu kungalungiswa ngezibuko zokufunda. Uma ukuqina kwelensi kuqhubekela phambili ku-cataract, ukufaka ama-lens ngokuhlinzwa ngokuvamile kuphephile futhi kuguqula ukulahleka kombono.
Amathiphu ngempilo yamehlo
Njengoba ukhula, kubalulekile ukuthi ube nokuhlolwa kwamehlo okuphelele okujwayelekile ukubamba izimo ezifana ne-nuclear sclerosis kanye ne-cataract kusenesikhathi. Uma ubona izinguquko kumbono wakho, ikakhulukazi izinguquko ezingazelelwe, hlola iso.
I-American Academy of Ophthalmology incoma ukuthi uthole ukuhlolwa okuyisisekelo kwamehlo lapho uneminyaka engama-40 noma ngokushesha uma usengozini enkulu ngenxa yalokhu:
- isifo sikashukela
- umfutho wegazi ophakeme
- umlando womndeni wezifo zamehlo
Abantu abaneminyaka engama-65 nangaphezulu abasengozini ejwayelekile yezimo zamehlo kufanele bahlolwe njalo eminyakeni engu-1 kuye kwengu-2, njengoba kunconyiwe udokotela wakho. Ukuhlolwa kwamehlo okuphelele kuthatha imizuzu engama-45 kuye kwengama-90 futhi kuvame ukumbozwa umshuwalense wezokwelapha.
Okunye okubalulekile ekusizeni ukwehlisa ijubane izinguquko zelensi ukugqoka izibuko zelanga nokugwema ukubhema.
