Masomphenya zotumphukira

Nkhani lero wathu udzakhala zoyenera masomphenya ndi ntchito yake. Tingaonenso mmene zida zithunzi kuti ndi masomphenya zotumphukira, ndi ngodya kuonera amapezeka kuti thupi la munthu.

Imodzi mwa ntchito za ntchito ya zida za zithunzi ndi masomphenya zotumphukira. Udindo mbali zotumphukira wa diso. The chizindikiro chachikulu cha dzuwa ake - ngodya anthu a view. Pamafunikanso kuti mbali ya malo, amene amanena za maso athu ndi kuliika maso fixation pankhaniyi. Ntchito yaikulu ya masomphenya zotumphukira imatengedwa lathu mu mlengalenga.

Sonyezani munda wa view ali ndi phindu yeniyeni, Mzimuyo malire kwa diso. diso sagwirizana kuyera mu malire zotsatirazi: outwards - 90º, m'mwamba kunja - 70º, m'mwamba mkati - 55º, mkati - 55º, pansi mkati - 50º, pansi - 65º, pansi outwards - 90º. "Loss" zigawo munthu wotchedwa ng'ombe. M'dera zosatha ya munda wa view ali ndi thupi scotoma - otchedwa "akhungu banga". Mwachibadwa ndi kukhalapo angioskotom - riboni woboola "fallout" m'munda wa chidaperekedwa pamaso pa zotengera chachikulu retikalnyh, kutseka maselo photoreceptor. pamaso pawo kwangochepetsako pang'ono chabe impairs masomphenya zotumphukira ndipo amaona ponseponse.

Scotoma ndi mtheradi, wangwiro ndi "imfa" a chiwembu, ndi wachibale - ndi kuwonongeka zikusintha ntchito zithunzi mu imeneyi ankafufuza. Poyankha, mitundu iwiri anawagawa scotoma zabwino ndi zoipa. HIV angapezeke paokha: zimaonekera ngati mawanga mdima mu munda zithunzi, zimene zikusonyeza kuwonongeka kwa diso. Wachisoni scotoma mankhwala omwewo si wapezeka ndipo amaoneka chifukwa cha kuwonongeka njira. Iwo kawirikawiri kuzindikiridwa pa kafukufukuyu. Pali scintillating scotoma. Monga ulamuliro, maonekedwe awo satsatira dongosolo lililonse ndipo mowiriza kwathunthu. Ngati wodwala ndi maso chatsekedwa kuonera osiyanasiyana yokhotakhota mizere anatambasula masomphenya zotumphukira, kumachitika kuphipha ziwiya ubongo. Kusiya ndondomeko imeneyi ndi kusintha kwa zinthu, madokotala amavomereza yomweyo kuyamba kumwa mankhwala antispasmodic.

Scotoma pa malowa akhoza wachinsinsi motere:

• zotumphukira;
• paracentral;
• chapakati.

Pansipa, ife azipereka mndandanda wa mavuto masomphenya zimene zimachititsa kuwonongeka wa zotumphukira zithunzi likukula.

Kuchepetsa ya munda wa masomphenya kumbali zonse 5 - 10 madigiri chifukwa cha kuwonongedwa kwa mitsempha ndipo retinal dystrophy. zodabwitsazi amatchedwa concentric chidule za kuthengo zithunzi. Childs, zimenezo, munthu akadali amaona ndipo ngakhale kuwerenga, koma luso oyendetsa yekha malo Mwamsanga kwathunthu ndipo kwambiri chatsika masomphenya.

Zikatero, ngati wodwalayo wataya malo symmetrical review, m'pofunika kuthetsa kuti akatswiri chifukwa bwinobwino. zizindikiro zotere nthaŵi limasonyeza kukhalapo kwa chotupa wodwalayo, kukha mwazi ndi matenda ena oopsa. Mu magawo oyambirira a zotupa ndi inflammations akhoza kudzakhala imfa ya mbali chabe ya kubwerezako, T. E. Ataye limodzi mwa magawo anayi a m'munda wa view. Mu kudwala kwa diso, masomphenya akhoza kutayika m'madera osiyana. Mwachitsanzo, khungu itsekeke pang'ono m'munda wa view a mbali m'mphuno.

Kusanthula khalidwe malire m'munda wa view, mmisiri waluso akhoza kudziwa kutanthauzira kwa zotupa mu madera osiyana a njira ya zithunzi, komanso kuchuluka kwa zotupa osachiritsika GAWO khungu, ndipo magawo ena.
