Macular kudzikira
Seizvo zita rinoratidzira, iyo macular degeneration zvinokonzerwa nekuparara kwe macula, nzvimbo diki ye retina iri pazasi peziso, pedyo netsinga yemaziso. Iri kubva kuchikamu ichi che retina iyo yakanyanya kunaka yekuona acuity inouya. Macular degeneration inotungamira kune zvishoma nezvishoma kurasikirwa uye dzimwe nguva zvakakosha zve chiratidzo chepakati, iyo inova isina kujeka zvikuru.
Macular degeneration inonyanya kubata vanhu vane makore makumi mashanu nemashanu zvichikwira. Inobva yasarudzwa nekutaura Macular kudzikira ou AMD. Kune nzira dzakasiyana-siyana dzekudzikisa kufambira mberi kwezera-rinoenderana nezera remacular degeneration.
Kune zvakare fomu nhaka yechirwere ichi, icho chinoparadzirwa kuburikidza nemajini: Chirwere cheStargardt. Izvi zvinoitika panguva yehudiki kana kuyaruka. Mupepa iri, hazvizokurukurwa.
Zvikonzero zvemacular degeneration
Zvinhu zvakasiyana-siyana zvinogona kukonzera macular degeneration. THE'zera ndiyo inonyanya kukosha yengozi. Anenge munhu mumwe chete pavanhu 1 vane makore 7 kusvika ku55 anacho, uye 64 muvatatu pane vane makore 1 zvichikwira.22. Vanhu vane nhoroondo yemhuri macular degeneration inonyanya kukanganiswa.
The maitiro ehupenyu kuita basa rinokosha. Kusvuta chinhu chikuru chengozi: zvichienzaniswa nevasingasvuti, vanosvuta vane 2 kusvika ku3 nguva yakawanda yekuva nechirwere ichi rimwe zuva.19. Pamusoro pezvo, chero chinhu chinotadzisa kuyerera kweropa kumatumbu eziso chinowedzera njodzi. Izvi ndizvo zvakaita hypertension uye hypercholesterolemia.
Muchidzidzo che epidemiological chevakadzi ve1 vane makore 113 kusvika ku55, vanhu vaidya zvakanaka, vasingasvuti uye vaive vakagwinya vaive ne74 nguva shoma vari panjodzi yekuparara kwema macular pane avo vakatora mararamiro akaipisisa.20. The impact force of nzira yehupenyu zvinogona kusiyana kubva kune mumwe munhu kuenda kune mumwe, zvichienderana neiyo nhaka yenhaka.
Pakupedzisira, kuzvimba kunogona kukonzera kutanga kwechirwere. Zvechokwadi, vatsvakurudzi vakawana kuwirirana pakati pemazinga eropa eC reactive protein, chiratidzo chekuzvimba, uye macular degeneration.2.
Mhando dzemacular degeneration
- Zera-yakabatana yakaoma macular degeneration. Iyo inonziwo zera-yakabatana atrophic kana isiri-neovascular macular degeneration, ndiyo yakaderera fomu uye kazhinji kazhinji kuderera kwe macular degeneration. Inoshanduka kwemakore akawanda. Zvose zvinokonzerwa nezera-macular degeneration zvinotanga nefomu yakaoma isati yafambira mberi, munenge 1 muvanhu gumi, kusvika kune iyo yakanyorova.
- Zera-rinoenderana wet macular degeneration. Iyo inonziwo exudative kana neovascular, iyi fomu ye macular degeneration ndeyekuwedzera kweiyo yakaoma fomu. Iyo inoratidzirwa nekuumbwa kwe mitsva yeropa muchoroid, pasi pe retina. Ropa kana zvimwe zvinwiwa zvinogona kubuda uye kuwedzera kukuvadza macula. Zvinokonzera kurasikirwa kwekuona nekukurumidza kupfuura fomu yakaoma, dzimwe nguva mukati memazuva kana mavhiki. Iyo yakanyorova fomu inogona kutungamirira mukurasikirwa kwakakwana kwepakati pekuona. Hazvinyatsonzwisiswi kuti chii chinoita kuti tsinga dzeropa idzi dziumbe.
Dambudziko rekuona pigment Chiedza chinopinda muziso kuburikidza nelenzi. Mwaranzi yechiedza inomhara paretina, kamukanda katete kanovhara mukati meziso. Iyo retina inoumbwa, pakati pezvimwe zvinhu, photoreceptor nerve masero: pasikweya uye sticks. Masero aya anodiwa pakuona zvakanaka nekuti anopindirana nemavara uye kusimba kwechiedza. Visual acuity ndiyo yakanyanya kunaka mu macula, nzvimbo diki iri pakati pe retina. Iyo macula inobvumira kuona kwepakati. Vanhu vane macular degeneration vane zviduku, zvipembenene zveyero mumacula avo, anonzi drusens kana madhiri. Izvi zvinoshanduka kuita vanga. Ichi chiitiko chigumisiro chekubviswa kusina kunaka kwe mavara ekuona, photosensitive zvinhu zviri mu photoreceptor masero. Munguva dzakajairika, mavara aya anobviswa uye anogara achivandudzwa. Mune avo vanobatwa, vanounganidza mu macula. Nekuda kweizvozvo, zvakanyanya kuomera kuti tsinga dzeropa dzipe macula. Mushure mechinguva, maziso anotadza kuona. |
Evolution ye macular degeneration
Kana yakaoma fomu, vanhu vakawanda vacharamba vachiona zvakanaka muupenyu hwavo hwose kana kuti zvishoma nezvishoma vacharasikirwa nechiono chavo chepakati. Iyi fomu ye macular degeneration hairapike. Kune rimwe divi, kushanduka kwayo kunogona kudzikiswa nekutora mamwe mavhitamini e antioxidant uye kurovedza muviri. Sezvo chirwere ichi chinogona kuramba chiri asymptomatic kwenguva yakareba, izvi zvinogona kunonoka kuongororwa uye nekudaro kurapwa - izvo zvinogona kuderedza kushanda kwayo.
Kana nyoro fomu, vanhu vanogona kukurumidza kurasikirwa nechiono chavo chepakati. Sezvineiwo, kune marapirwo ekurapa nyoro fomu. Ichi chimiro chinokonzera zviratidzo nekukurumidza: kudonha kamwe kamwe muchiratidzo uye kukanganisa kwezvinhu (mitsetse yakatwasuka inoshatiswa).
Kune ese ari maviri mafomu ezera-ane hukama macular degeneration, kuona kunogona kuderera mune rimwe ziso uye kuramba mune rimwe kwemakore.
Chirwere ichi usambotsamwisa de upofu hwakazara sezvo kuona kweparutivi kunoramba kwakasimba.
