Umntwana osandul 'uzalwayo uzalwe ngumbono obude. Ubuntwaneni, izifo zamehlo ziqhelekile. Izifo ezinjalo zibandakanya i-hypermetropia (ukugqithisa) - uhlobo lokuphula umthetho, apho umntwana ebona ngokucacileyo umgama, kodwa izinto ezikufutshane ziphazamisekile. Njengomthetho, uqhubeka ude uneminyaka engama-7 kwaye unokuphela ngokupheleleyo ngenxa yokuphuhliswa kwenkqubo ebonwayo. Kwezinye iimeko, i-hyperopia ingena kwi-myopia.
I-Hyperopia yeli liyabantwana: kubangele
I-hyperopia ingabangela izizathu ezilandelayo:
- umsebenzi obuthathaka kwinkqubo yokucoca;
- ubukhulu becala liso;
- utshintshe umlo we-eyeball;
- ukuzalwa.
Amagatya e-hypermetropia
Kukho amazinga amathathu okujonga:
- ababuthathaka (ukuya kwi-diopters ye-2);
- umyinge (2-5 diopters);
- phezulu (ngaphezu kwe-5 diopters).
- I-Hypermetropia yezinga elibuthathaka kubantwana liqhelekileyo ngenxa yokuphuhliswa kweminyaka kwaye ayifuni ukulungiswa okukhethekileyo. Xa umntwana ekhula, isakhiwo saso sitshintsha: i-eyeball ibonisa ubungakanani, imisipha yamehlo iqina, kwaye ngenxa yoko umfanekiso uqala ukwenza i-retina ngokwayo. Ukuba ukugqithisela akudluli ngaphambi kokuba uneminyaka engama-7, kufuneka udibanise ne-ophthalmologist yezilwanyana ekukhetheni unyango olufanelekileyo.
- I-Hypermetropia yezinga elimodareyithwa kubantwana ayifuni ukungenelela ngoncedo. Ugqirha ukhetha ukugqoka iiglasi ukuze usebenze kwibala elifutshane, umzekelo, ngelixa ufunda nokubhala.
- I-Hypermetropia yezinga eliphezulu kubantwana lifuna ukulungiswa rhoqo kwamehlo kunye nezibuko okanye ngoncedo lwama-lens.
Hypermetropia kubantwana: unyango
Ingozi ye-hypermetropia yinkxalabo enokwenzeka emva koko kwisakhiwo nokusebenza kwenkqubo yokubonwa:
- i-amblyopia (ukuphungula umbono kwiso linye);
- i-strabismus;
- microphthalmos;
- I-disseudo-optic disc ye-optic nererve;
- i-alpha engqinelanayo.
Ukulungiswa kwe-hypermetropia kubantwana kuqhutyelwa ngoncedo lwama-lens athile nakwiimeko zokuxilongwa ngezinga elincinci, ngaphandle kokuba kungekho nxinano. Oku kuya kuthintela ukuphuhliswa kweengxaki kunye nokukhubazeka okubonakalayo.
Ukongezelela ekulungiseni iziglasi kunye neelensi, ezi ndlela zonyango kunye nokukhuselwa kweengxaki zingasetyenziswa:
- ukucoca umzimba;
- unyango lwe ultrasound;
- unyango olumandla;
- ukuchithwa kwelanga kweso;
- iyeza laser;
- uqeqesho lwe-auto-computer.
Ezi ndlela zonyango ziyakunciphisa i-spasm yokuhlala kunye nokuphucula inkqubo yokuxilongwa kweso.
Kufuneka kukhunjulwe ukuba ukufumanisa ngexesha kunye nokulungiswa kwezifo zamehlo ezikhoyo kuza kusindisa umbono womntwana.
