Kuberekwa cataract

Kuzvarwa cataract ndiko kudzikamisa kwemaziso eziso iro riripo pakuzvarwa. Iyo lens yeziso inowanzo kujeka. Inotarisa mwenje unouya muziso pane iyo retina.

Kusiyana nemakara mazhinji, ayo anoitika nekukwegura, kuberekwa kwemaziso kunowanikwa pakuzvarwa.

Kuberekwa kwemaziso kunowanzoitika. Muvanhu vazhinji, hapana chikonzero chinogona kuwanikwa.

Kuberekwa kwemaziso kunowanzoitika sechikamu chekukanganisa kwekuberekwa kunotevera:

• Chondrodysplasia chirwere
• Kuberekwa rubella
• Conradi-Hünermann chirwere
• Down syndrome (trisomy 21)
• Ectodermal dysplasia syndrome
• Kuzivikanwa kwekuzvarwa kwemaziso
• Galactosemia
• Hallermann-Streiff chirwere
• Lowe chirwere
• Marinesco-Sjögren chirwere
• Chirwere chePierre-Robin
• Trisomy 13

Congenital cataract kazhinji inotaridzika zvakasiyana kupfuura mamwe maratidziro.

Zviratidzo zvinogona kusanganisira:

• Mwana mucheche anoita kunge asiri kuona pasirese nyika yakavapoteredza (kana katsi iri mumaziso ese)
• Grey kana chena kuchena kwemudzidzi (izvo zvinowanzo kuve nhema)
• I "ziso dzvuku" kupenya kwemudzidzi kuri kushaikwa mumifananidzo, kana rakasiyana pakati pemaziso maviri
• Kufamba kusingawanzo kufamba kwemaziso (nystagmus)

Kuti uongorore kuberekwa kwemaziso, mucheche anofanira kuve nekuongororwa kwakakwana kwemaziso na ophthalmologist. Mucheche anogona zvakare kuda kuongororwa nachiremba wevana ane ruzivo mukurapa kusagadzikana kwakagara nhaka. Kuongororwa kweropa kana x-ray kunogona kudiwa zvakare.

Kana congenital cataract iri nyoro uye isingakanganise kuona, vangangodaro vasingadi kurapwa, kunyanya kana vari mumaziso maviri.

Pakati nepakati kusvika pakakomba pakaipa zvinokanganisa kuona, kana chirwere chiri muziso rimwe chete, chinoda kurapwa nekuvhiya kwekatsi. Mune mazhinji (noncongenital) cataract kuvhiya, yekugadzira intraocular lens (IOL) yakaiswa muziso. Iko kushandiswa kweIOLs muvacheche kunopokana. Pasina IOL, mucheche anozoda kupfeka lenzi yekuonana.

Kubata kumanikidza mwana kuti ashandise ziso risina kusimba kunowanzodiwa kudzivirira amblyopia.

Mucheche anogona zvakare kuda kurapwa chirwere chakagarwa nhaka chiri kukonzera maziso.

Kubvisa kuberekwa kwemaziso kunowanzove nzira yakachengeteka, inoshanda. Mwana anozoda kuteedzerwa kuitira kugadzirisa chiratidzo. Vazhinji vacheche vane mwero we "ziso rine usimbe" (amblyopia) pamberi pekuvhiya uye vanozoda kushandisa chigamba.

Nekuvhiyiwa kwekati kune njodzi shoma ye:

• Kubuda ropa
• Utachiona
• Kuzvimba

Vacheche vanovhiyiwa kuberekwa kwemaziso vanogona kukudziridza rumwe rudzi rwecataract, iyo ingangoda kumwe kuvhiyiwa kana kurapwa kwemalasi.

Zvakawanda zvezvirwere zvinosanganisirwa nekuzvarwa cataract zvinogona zvakare kukanganisa dzimwe nhengo.

Dana musangano wekukurumidzira nemubatsiri wehutano hwemwana wako kana:

• Unocherekedza kuti mwana weziso rimwe kana maviri maziso anoonekwa akachena kana kuchera.
• Mwana anoita seasina hanya nechikamu chenyika yavo yekuona.

Kana iwe uine nhoroondo yemhuri yezvinetso zvekugara nhaka zvinogona kukonzeresa kuberekwa kwemaziso, funga kutsvaga kwehungwaru.
