Kawirikawiri, mukapita kukayezetsa maso, izi (Visual Acuity Test) zimachitikadi. Madokotala amachita izi kuti azindikire kusintha kulikonse m'maso mwanu pakapita nthawi.

Pali mavuto angapo a maso omwe nthawi zambiri amatha kuzindikirika ndi mayeso awa:

• Myopia : Kulephera kuona zinthu zakutali bwino.
• Kuona Pafupi (Hyperopia): Kulephera kuona zinthu pafupi, makamaka powerenga.
• Astigmatism : Kusawona bwino chifukwa cha diso lomwe silikuyang'ana bwino kuwala.
• Presbyopia : Kutaya masomphenya pafupi ndi ife tikamakalamba. Nthawi zambiri kumayamba munthu akakwanitsa zaka 40.
• Kusazindikira mitundu : Kulephera kusiyanitsa mitundu ina.

Kodi muyenera kuyesedwa maso anu kangati?

Mwa kuyang'ana maso ndi maso anu nthawi zonse, dokotala wanu wa maso amatha kuzindikira mavuto aliwonse msanga . Kuchuluka kwa mayeso anu a maso nthawi zambiri kumasiyana malinga ndi zaka zanu:

• Ana aang'ono: Dokotala wa ana ayenera kuyang'anitsitsa maso a mwana wanu nthawi iliyonse yopita kukaonana ndi dokotala wa ana mpaka atayamba sukulu, kenako chaka chilichonse kapena ziwiri pambuyo pake.
• Akuluakulu osakwana zaka 40: Zaka zisanu mpaka khumi zilizonse.
• Akuluakulu azaka zapakati pa 40 ndi 54: Zaka ziwiri kapena zinayi zilizonse.
• Akuluakulu azaka zopitilira 55: Kamodzi pa chaka chimodzi mpaka zaka zitatu zilizonse.

Komabe, ngati mumavala magalasi kapena ma contact lens, kapena muli ndi matenda monga matenda a shuga, mungafunike kuyesedwa maso anu pafupipafupi . Ndi bwino kufunsa dokotala wa maso anu kangati komwe muyenera kuyesedwa maso anu.

Ndani amachita izi (Kuyesa Kuwona)?

Nthawi zambiri, mayesowa amachitidwa ndi katswiri wa maso , yemwe angakhale dokotala wa maso kapena wa maso.

Nthawi zina, ngakhale dokotala wanu angachite izi (Visual Acuity Test), makamaka ngati mupita kukaonana naye ali ndi zizindikiro zilizonse za maso.

Kodi pali mitundu iti ya mayeso a Visual Acuity Test?

Pali njira zosiyanasiyana zoyesera masomphenya anu. Nazi zina mwa njira zodziwika kwambiri zoyesera kuwona bwino:

• Tchati cha maso a Snellen: Ili ndi bolodi lokhala ndi mizere ya zilembo pakhoma lomwe mumakumbukira mukamva za mayeso a maso. Zilembozo ndi zazikulu pamwamba, ndipo zilembozo zimakhala zazing'ono mukamazisiya pansi. Dokotala adzakuuzani kuti muziziwerenga mpaka mutaziwerenga bwino. M'malo ena, izi zimawonetsedwa pakhoma kapena kuonetsedwa pazenera.

• Tchati cha Random E: Ichi chikufanana ndi tchati cha Snellen. Koma m'malo mwa zilembo zosiyana, chili ndi chilembo "E" chokha. Chilembo cha E ndi chaching'ono komanso chaching'ono, chozungulira, chozondoka, ndi chozungulira mbali zosiyanasiyana. Muyenera kuchiwerenga mpaka mutalephera kudziwa komwe chilembo cha E chili.

• Mayeso a Dynamic Vision Acuity: Mu mayeso awa, dokotala akugwira mutu wanu ndikuwugwedeza pang'onopang'ono kuchokera mbali imodzi kupita mbali ina kuti awone momwe mukuonera. Mayesowa amawunika ngati mungathe kusunga maso anu mosasunthika pamene mutu wanu ukuyenda (izi zimatchedwa vestibulo-ocular reflex).

• Mayeso a Pinhole Visual Acuity: Iyi ndi mayeso omwe adapangidwa kuti azindikire kuwona pafupi, kapena myopia. Monga mayeso wamba, mumapatsidwa chipangizo chotchedwa paddle chomwe chimaphimba diso limodzi. Komabe, lili ndi mabowo ang'onoang'ono amodzi kapena angapo (pinholes). M'malo moyang'ana kudzera m'diso lina, mumawerenga tchati cha Snellen kapena Random E kudzera m'mabowo awa.

• Mayeso a kuwona bwino kwa ana: Pali njira zingapo zoyesera kuwona bwino kwa ana azaka zosiyanasiyana. Mwina munamvapo za mayeso a kuwona bwino a Cardiff. Mayeso ena amagwiritsa ntchito zithunzi kapena ma diagram m'malo mwa zilembo. Mungapatsidwenso zilembozo papepala lina ndikupemphedwa kuti mugwirizane ndi zilembo zomwe zili pakhoma.

Kodi mungatani kuti muyesere mayeso a Visual Acuity?

Mayeso ambiri a kuwona bwino amachitidwa motere:

1. Mudzayikidwa kapena kuyimitsidwa pamtunda wa mamita 20 kuchokera pa chikwangwani chokhala ndi zilembo.

2. Kenako dokotala adzakuuzani kuti mutseke diso limodzi (nthawi zambiri ndi dzanja lanu, kapena ndi bolodi laling'ono limenelo).

3. Kenako, amauzidwa kuti awerenge pang'onopang'ono kuyambira pamzere wapamwamba wa zilembo zazikulu kupita pansi .

4. Muyenera kupitiriza kuwerenga mpaka mutatha kuwona zilembo kapena zizindikiro bwino .

5. Mukamaliza ndi diso limodzi, tsekani diso linalo ndikubwereza mayeso kuyambira pachiyambi.

Palibe vuto kuyesa kuganiza ngati mukuvutika kuwerenga zilembozo pamene zikutsika. Komabe, ngati muyamba kuona zilembozo zikuoneka ngati sizikumveka bwino kapena zikuvuta kuwerenga, uzani dokotala wanu. Musamatseke maso kapena kupotoza maso anu. Cholinga cha mayesowa ndikupeza kuwunika kolondola kwa maso anu. Choncho musadandaule za "kulephera" kapena "kulephera" mulimonsemo.

Ngati mwavala kale magalasi kapena ma contact lenses, dokotala wanu angachite izi (Visual Acuity Test) kangapo. Izi zikutanthauza kuti maso anu adzawunikidwa popanda magalasi anu (izi zimatchedwa uncorrected vision) komanso ndi magalasi anu (izi zimatchedwa corrected vision).

Kodi pali chilichonse chomwe ndikufunika kukonzekera ndisanachite izi (Visual Acuity Test)?

Ayi, palibe kukonzekera kwapadera kofunikira. Ngati muvala magalasi kapena ma contact lenses, onetsetsani kuti mwawabweretsa mukabwera kudzayezetsa maso anu. Dokotala angachotsedwe ndikuyezetsa maso anu osakonzedwa.

Kodi chimachitika ndi chiyani pambuyo pa mayeso a Visual Acuity?

Pambuyo poti mayeso a maso anu atha, dokotala wanu wa maso adzamaliza mayeso ena onse a maso. Mungafunikenso kuchita mayeso ena, monga mayeso a Slit Lamp. Izi zidzayang'ana matenda ena omwe angakhudze maso anu, monga:

• Matenda a Cataract
