I-Astigmatism kubantwana abangaphantsi komnyaka omnye ubudala
Ukuxilongwa kwe-astigmatism kwintsana kungenziwa kuphela yi-oculist. Kule minyaka uhlala efa. Kukho iindlela ezimbini zokuxilonga:
- Ngoncedo lwee-refractometers (i-refractometer okanye i-Harklinger refractometer).
- Ngendlela yokuhlolwa kwesitimu (skiascopy).
Unyango luqeshwe ngabanye, luqwalasele zonke izinto ezichaphazela ukuphuhliswa kunye nesithintelo kwisifo. Kuze kube unyaka, i-astigmatism kubantwana ixhaphake kakhulu kwiifom ezincinci. Kwixesha elizayo, umbono ulingana kunye kunye neemviwo eziqhelekileyo ze-ophthalmologist, kunye nayo yonke imiqathango kadokotela, i-astigmatism ilawulwa kwaye iphathwe.
I-Astigmatism kwiimpawu zezingane
- ukhathala okwandisiweyo kunye nomsebenzi obonakalayo obude (ukufunda iincwadi, ukubukela iTV, ukusebenza kwikhompyutha);
- iintloko ngexesha okanye emva komthwalo obonakalayo;
- iphosakele, idibanise okanye ibonwe umbono wezinto.
Unyango lwe-astigmatism kubantwana
Ngokuqhelekileyo i-astigmatism kubantwana ibonakaliswe nge-hyperopia okanye i-nearsightedness. Kukho iintlobo ezintathu ze-astigmatism:
- I-astigmatism edibeneyo ( ukujonga okufutshane kweso kunye nokujonga kwangaphambili kwesibini). Nge-astigmatism edibeneyo kubantwana, ubunzima obubonakalayo obubonakalayo.

Kukho nezixhobo zokwenza uqeqesho olubonakalayo. Indlela ephakamileyo yokulungiswa kombono iiglasi kunye neelenzi zeclindrical (ezibizwa ngokuthi "iiglasi eziyinkimbinkimbi") okanye ii-lens (kunye nexesha lethu, iilensi zentsimbi zenziwe, zenza ukuphazamiseka okuncinci emehlweni). Uvavanyo oluqhelekileyo lufunekayo ukuze kufakwe iiglasi, kuba izibonakaliso ze-dioptric ze-astigmatism ezixutywa kubantwana zihlala ziguquka.
- I-Myopic (myopic). I-astigmatism ye-Myopic kubantwana inokuphuhliswa kumazinga aphakamileyo aphantsi. Qinisekisa kuya kunceda ophthalmologist ngexesha lokuqeshwa ngokuqhelekileyo. Iphathwe kubantwana ngokuncediswa kwindlela yokulondoloza (i-gymnastics yeziliso, ukondla okukhethekileyo, iiglasi, iilensi). Ukuhlinzwa kunye nokulungiswa kwelayisensi kuvumelekile emva kwe-18
minyaka. - I-hypermetropic (ende ende) njenge-astigmatism kubantwana.
