Khungu khungu

Khungu khungu ndiko kulephera kuwona mitundu ina mwa njira yanthawi zonse.

Khungu khungu zimachitika pamene pali vuto ndi inki mu maselo ena mitsempha ya diso kuti mtundu mtundu. Maselowa amatchedwa ma cones. Amapezeka m'thambo lakhungu kumbuyo kwa diso, lotchedwa retina.

Ngati mtundu umodzi wokha ukusowa, mutha kukhala ndi vuto kusiyanitsa ofiira ndi obiriwira. Uwu ndiye mtundu wofala kwambiri wakhungu. Ngati mtundu wina ukusowa, mutha kukhala ndi zovuta kuwona mitundu yabuluu yachikaso. Anthu omwe ali ndi khungu la khungu lachikasu nthawi zambiri amakhala ndi vuto lowona zobiriwira komanso amadyera, nawonso.

Mtundu wakhungu kwambiri wakhungu ndi achromatopsia. Izi ndizovuta kwambiri momwe munthu samatha kuwona mtundu uliwonse, koma mithunzi yokha yaimvi.

Khungu khungu ambiri chifukwa cha vuto chibadwa. Pafupifupi m'modzi mwa amuna khumi ali ndi khungu lakuda. Ndi azimayi ochepa kwambiri omwe ndi akhungu.

Mankhwala a hydroxychloroquine (Plaquenil) amathanso kuyambitsa khungu khungu. Amagwiritsidwa ntchito pochiza nyamakazi ya nyamakazi ndi zina.

Zizindikiro zimasiyanasiyana malinga ndi munthu, koma zimaphatikizapo:

• Kuvuta kuwona mitundu ndi kuwala kwa mitundu m'njira wamba
• Kulephera kuzindikira kusiyana pakati pa mithunzi yofanana kapena yofanana

Nthawi zambiri, zizindikiro zimakhala zofewa kwambiri kotero kuti anthu sangadziwe kuti ndi akhungu. Kholo limawona zizindikiro zakhungu khungu mwana wakhanda akangoyamba kuphunzira mitundu.

Kusuntha kwamaso mwachangu, mbali ndi mbali (nystagmus) ndi zizindikilo zina zimatha kupezeka pamavuto akulu.

Wothandizira zaumoyo wanu kapena katswiri wamaso amatha kuwona mawonekedwe anu m'njira zingapo. Kuyesera khungu lakhungu ndi gawo lofala pakuwunika kwamaso.

Palibe mankhwala odziwika. Magalasi apadera olumikizirana ndi magalasi amatha kuthandiza anthu omwe ali ndi khungu khungu kudziwa kusiyana pakati pa mitundu yofananayo.

Khungu khungu ndi moyo wonse. Anthu ambiri amatha kuzolowera.

Anthu omwe mtundu wa colorblind sangathe kupeza ntchito yomwe imafuna kutha kuwona mitundu molondola. Mwachitsanzo, opanga zamagetsi, ojambula, komanso opanga mafashoni amafunika kuti azitha kuwona mitundu molondola.

Itanani omwe akukuthandizani kapena katswiri wamaso ngati mukuganiza kuti inu (kapena mwana wanu) mungakhale ndi khungu losawoneka bwino.

Kusowa kwamitundu; Khungu - mtundu
