Ingabe ukubona kwakho kuncipha kancane kancane? Lokhu kungaba yi-Corneal Ectasia!

Ingabe ngezinye izikhathi uzizwa sengathi ukubona kwakho kuncipha kancane kancane? Mhlawumbe awukwazi ukubona kahle njengakuqala, futhi amehlo akho aba luhlaza okwesibhakabhaka uma ubheka ukukhanya? Esinye sezizathu zalokhu kungaba yisimo samehlo esikhethekile. Namuhla sizokhuluma ngesinye isimo esinjalo, esidinga ukunakwa okuncane, esibizwa ngokuthi i-corneal ectasia . Ungesabi, into ebaluleke kakhulu ukuqaphela lokhu.

Iyini i-Corneal Ectasia?

Kalula nje, i-corneal ectasia iyiqembu lezimo ezithinta i-cornea (ingxenye ecacile, eyindilinga yangaphambili yeso, njengelensi yekhamera). Okwenzekayo kulokhu ukuthi isimo se-cornea yakho siyashintsha kancane kancane. I-cornea iyancipha futhi iqhume phambili. Cabanga ngayo njengebhaluni elincane elivuvukalayo. Lokhu kushintsha indlela ukukhanya okungena ngayo iso, okubangela i-astigmatism (iphutha lokubona) elinganda ngokuhamba kwesikhathi. Ngenxa yalokho, umbono wakho uba buthakathaka ngokuhamba kwesikhathi. Ngokuvamile, lesi simo sithinta womabili amehlo, kodwa ngezinye izikhathi singathinta iso elilodwa nje. Kwabanye abantu, le- corneal ectasia ingaba mnene kangangokuthi ayitholakali ngisho nokuhlolwa kwezokwelapha. Kodwa njengoba lokhu kuqhubeka, umbono wakho ungaba mpofu kangangokuthi awukwazi ukubona kahle ngisho nangezibuko noma ama-contact lens. Kodwa-ke, izinkinga ezinkulu njengokungaboni azivamile, ngakho-ke akukho okufanele ukhathazeke ngakho. Kodwa-ke, umbono ompofu ungaphazamisa imisebenzi yakho yansuku zonke, njengokuya emsebenzini noma ukunakekela umndeni wakho. Ngakho-ke, kubaluleke kakhulu ukuxilonga lesi simo kusenesikhathi futhi ufune ukwelashwa okudingekayo.

Yiziphi izinhlobo ze-cornea ectasia?

Kunezinhlobo eziningana eziyinhloko ze-corneal ectasia . Ake sibheke ukuthi ziyini ngamagama alula:

I-Keratoconus

Lolu uhlobo oluvame kakhulu lwe-cataract . Kulesi simo, i-cornea iyancipha bese iqhuma kancane kancane ibe yisimo esimise okwe-cone. I-cornea, evame ukuba yindilinga, iba yisimo se-cone. Cabanga ngayo njengengxenye ephezulu ye-ayisikhilimu cone.

I-Keratoglobus

Kulokhu, lonke i-cornea liba mncane ngendlela engavamile futhi liqhume phambili ukuze livumelane nalo. Lonke i-cornea lingase libonakale liqhume, njengebhola elikhulu.

Ukuwohloka kwe-pellucid emaphethelweni

Kulokhu, ungabona ukuncipha engxenyeni engezansi ye-cornea, njengenyanga ecwebezelayo. Lokho kuncipha kubangela ukuthi i-cornea iphume phambili isuka phezulu.

I-ectasia yokuhlinzwa ngemva kokususwa kwezicubu

Lokhu kukhethekile kancane. Kwenzeka ngemva kokuhlinzwa ukuze kulungiswe izinkinga zokubona njenge- myopia ( ukubona eduze).I-Corneal ectasia . Isibonelo yi -post-LASIK ectasia . Kulinganiselwa ukuthi cishe umuntu oyedwa kwabayi-166 abahlinzwa amehlo nge-LASIK uzoba nalesi simo. Singenzeka futhi ngemva kokunye ukuhlinzwa kwe-cornea, njenge -PRK .

I-ectasia ye-keratoplasty engemva kokungena

Kulesi simo, i-ectasia ivela njengenkinga yokufakelwa i-cornea . Ivame ukuthinta abantu abaye bafakelwa i-cornea njengendlela yokwelapha isimo i -keratoconus . Ingenzeka cishe kumuntu oyedwa kwabayi-10 phakathi neminyaka eyi-10 yokuhlinzwa.

Ubani othinteka kakhulu yilesi simo?

I-corneal ectasia ingenzeka kubantu banoma yimuphi ubudala nohlanga. Ayihlukanisi phakathi kwabesilisa nabesifazane. Ngezinye izikhathi ingaqala ebuntwaneni futhi iqhubeke kuze kube seminyakeni ephakathi noma ngisho nangemuva. Ubudala lapho izimpawu ziqala khona (ukuqala) buyahlukahluka kuye ngohlobo:

• I-Keratoglobus : Ngokuvamile kwenzeka ebuntwaneni noma ebusheni (abaneminyaka eyi-10).
• I-Keratoconus : Ubuntwana obuncane (ekupheleni kweminyaka eyi-10 kuya kweye-20).
• Ukuwohloka kwe-pellucid marginal : Ngeminyaka yama-20, yama-30, noma yama-40.
• I-ectasia yangemva kokuhlinzwa : Noma nini kusukela ezinyangeni ezimbalwa kuya eminyakeni ngemva kokuhlinzwa .

Ziyini izimpawu ze-Corneal Ectasia?

I-corneal ectasia ingase ingabi nazimpawu ezigabeni zokuqala. Kodwa-ke, njengoba isimo siqhubeka, izimpawu ezifana nalezi:

• Ukubona kuya ngokuya kuba kubi ngokuhamba kwesikhathi.
• Ukukhazimula lapho ubheka ukukhanya . Abanye abantu bathi kuzwakala sengathi amehlo abo ayavutha.
• Ama-Halos: Ukubona indandatho zizungeze izibani ngenkathi ushayela ebusuku.
• I-Diplopia (ukubona okuphindwe kabili) ukubona izithombe ezimbili esikhundleni sesithombe esisodwa.

Izimpawu ezivame kakhulu kulezi ukuwohloka kancane kancane kombono eminyakeni edlule. Ekuqaleni, lokhu kungaba yinto ecashile kakhulu, futhi ungase ukwazi ukulungisa kalula umbono wakho ngezibuko. Kodwa ngokuhamba kwesikhathi, umbono wakho ungaba mubi kangangokuthi ngisho nezibuko noma ama-contact lens awasakwazi ukusiza.

Kwezinye izinhlobo, njenge- keratoconus , kungenzeka ukuthi kube nezibazi ze-cornea, okunganciphisa nokubona kwakho.

Ingabe zikhona izinkinga eziyingozi ze-cornea ectasia?

Akuvamile kakhulu, i-corneal ectasia ingaholela ezinkingeni ezinkulu. Enye yalezi yi- corneal hydrops . Lesi yisimo lapho i-cornea ivuvukala khona ngokuzumayo bese iba namanzi. Lesi yisimo esiphuthumayo sezokwelapha . Sithinta cishe abantu abangu-3% abane -keratoconus . Izimpawu ze- corneal hydrops zifaka:

• Umbono ofiphele ngokuzumayo
• Ukuzwela okukhulu ekukhanyeni (amehlo aluhlaza okwesibhakabhaka)
• Ubuhlungu obusemehlweni ami abubekezeleleki.

Uma unalezi zimpawu, kufanele uye emnyangweni wezimo eziphuthumayo wesibhedlela esiseduze nawe ngokushesha. Lokhu kuyinto okungafanele ibambezelwe.

Yiziphi izimbangela zalokhu? Yiziphi izici eziyingozi?

Ngokuvamile kunzima ukukhomba imbangela eqondile ye-corneal ectasia . Izimo ezifana ne -keratoconus ne -keratoglobus zibonakala zisebenza emindenini (okusho ukuthi othile emndenini kungenzeka ukuthi wayenayo). I-Ectasia ngemuva kokuhlinzwa ingase ibangelwe ubuthakathaka be-cornea obungatholakalanga ngesikhathi sokuhlolwa kwangaphambi kokuhlinzwa. Ungase ube sengozini enkulu yokuthola i-corneal ectasia ngezizathu ezilandelayo:

• Uma unesifo sezicubu ezixhumeneyo , njenge- Ehlers-Danlos syndrome .
• Uma unesifo esikwenza uhlikihle amehlo njalo. Isibonelo , umkhuhlane we-hay , ukungezwani nothuli, noma i-eczema . Ukuhlikihla amehlo akho kaningi nakho kungaba nomthelela kulokhu, ngakho-ke kudingeka uqaphele nangalokho.
• Uma ugqoka ama-contact lens, ikakhulukazi ama-hard lens, isikhathi eside.
• Uma uke wahlinzwa ukulungisa umbono.

Ukuthola kanjani lokhu? (Ukuxilongwa)

Ochwepheshe bokunakekelwa kwamehlo baxilonga i-cornea ectasia ngokwenza okulandelayo:

• KuqediweKwenziwa ukuhlolwa kwamehlo okuphelele.
• Bazokhuluma nawe bakubuze ngomlando wakho wezokwelapha nokuthi ngabe kukhona yini emndenini wakho oke waba nezimo ezifanayo.
• Kuhlolwa okukhethekile, njengokuhlolwa kwesibani esinqunyiwe ( ukuhlolwa kweso ngesibani esinqunyiwe esikhethekile) kanye ne -topography ye-cornea ( ukuhlolwa okuthatha imephu yobuso be-cornea bese kubheka izinguquko esimweni sayo).
