Malo owoneka

Malo owonetserako amatanthauza malo athunthu omwe zinthu zimawoneka paziwonetsero (zotumphukira) pomwe mukuyang'ana kwambiri.

Nkhaniyi ikufotokoza mayeso omwe amayesa gawo lanu lowonera.

Kuyeserera koyang'ana pamunda. Ichi ndi cheke chachangu komanso chofunikira pakuwunika. Wothandizira zaumoyo amakhala kutsogolo kwanu. Mudzaphimba diso limodzi, ndikuyang'anitsitsa kutsogolo. Mudzafunsidwa kuti munene nthawi yomwe mungaone dzanja la woyesa.

Sangent screen kapena kuyesa kwa Goldmann. Mukhala pafupifupi mainchesi 90 (90cm) kutali ndi nsalu yotchinga, yakuda yokhala ndi chandamale pakati. Mudzafunsidwa kuti muyang'ane pa chandamale chapakati ndikudziwitsani woyesayo pamene mutha kuwona chinthu chomwe chimasunthira mbali yanu yamasomphenya. Chinthucho nthawi zambiri chimakhala pini kapena mkanda kumapeto kwa ndodo yakuda yomwe woyeserera amayisuntha. Mayesowa amapanga mapu a masomphenya anu apakatikati a 30. Mayesowa nthawi zambiri amagwiritsidwa ntchito kuti azindikire mavuto aubongo kapena mitsempha (neurologic).

Zojambula za Goldmann ndi zozungulira zokha. Pa mayesero onsewa, mumakhala kutsogolo kwa dome la concave ndikuyang'ana chandamale pakati. Mumasindikiza batani mukawona kuwala kochepa m'maso anu. Ndi kuyesa kwa Goldman, kuwalako kumayang'aniridwa ndikuwonetsedwa ndi wopimitsa. Pogwiritsa ntchito makina, makompyuta amayang'anira kuwala ndi mapu. Mayankho anu amathandizira kudziwa ngati muli ndi vuto m'mawonekedwe anu. Mayesero onsewa amagwiritsidwa ntchito kutsata zinthu zomwe zingawonjezeke pakapita nthawi.

Wopezayo amakambirana nanu mtundu wamayeso oyeserera omwe angachitike.

Palibe kukonzekera kwapadera kofunikira.

Palibe vuto lililonse poyesa kumunda.

Kuyesedwa kwa diso uku kukuwonetsa ngati mulibe masomphenya kulikonse komwe mungawone. Njira yakutaya masomphenya imathandizira omwe akukuthandizani kuzindikira chifukwa chake.

Masomphenya ozungulirawa ndi abwinobwino.

Zotsatira zachilendo zitha kukhala chifukwa cha matenda kapena matenda amitsempha yapakati (CNS), monga zotupa zomwe zimawononga kapena kupondereza (compress) ziwalo zaubongo zomwe zimachita ndi masomphenya.

Matenda ena omwe angakhudze mawonekedwe amaso ndi awa:

• Matenda a shuga
• Glaucoma (kuthamanga kwa diso)
• Kuthamanga kwa magazi
• Matenda okhudzana ndi zaka (matenda amaso omwe amawononga pang'onopang'ono masomphenya akuthwa)
• Multiple sclerosis (matenda omwe amakhudza CNS)
• Optic glioma (chotupa cha mitsempha yamagetsi)
• Chithokomiro chopitilira muyeso (hyperthyroidism)
• Matenda a pituitary
• Gulu la retina (kupatukana kwa diso kumbuyo kwa diso ndi zigawo zake)
• Sitiroko
• Temporal arteritis (kutupa ndi kuwonongeka kwa mitsempha yomwe imapereka magazi kumutu ndi mbali zina za mutu)

Mayesowo alibe zoopsa.
