iqembu semehlo - sisifo esibi ezigqeba umbono. Ngexesha uphuhliso esi sifo siyahlukana retina le choroid. Okwangoku, njengebutho le retina yeyona kakhulu phantsi kweemeko zophendlo lwezifo kunye notyando. Kule minyaka ilishumi idlulileyo siye sabona ukwanda ngcembe yale nosology. Minyaka le, iqembu semehlo kwenzeka abantu omnye 10,000 kwaye yenye ezibangela ngokungaboni nokukhubazeka. Phakathi madoda malunga nama-70% nokubandezeleka kulo disorder ngabantu abasebenzayo.

Unobangela ephambili looding semehlo kuba phambi umsantsa retina, ngalo, phantsi kwiretina iqala ndzulu fluid vitreous, njalo otslaivaya kuyo nxamnye choroid. Kwakhona kukho into kwindawo ukuphuhlisa zesifo ukuphazamiseka yokujikeleza, ekhokelela kukuvela iinkqubo sisiba mandundu, kwaye ngenxa yoko, ukuhlukumeza ubudlelwane phakathi umzimba vitreous kunye retina.

iqembu semehlo kuba buhlungu, sisiba mandundu, yaye idiopathic. Iimpawu eziphambili amehlo alilayo flash ebengezelayo phambi kwamehlo am njengombane. Imbonakalo lokuqhambuka sichazwe yi "nokuveza 'lo vitreous ukuya retina, ngelo xesha ithe fluid kunye retina uqalisa" angqubeke "kuyo. Izikhalazo malunga "umkhusane" okanye komkhusane phambi kwamehlo ethintela umbono eqhelekileyo kusenokuthetha ekuqaleni kwenkqubo looding semehlo. Phambi ezi mpawu imfuneko engxamisekileyo ukubona zamehlo eyodwa lokubhalela uviwo semehlo phambi kokuba imeko yaba kakhulu. Xa kungekho tyala kufuneka sizame ziphilise naziphi amathontsi okanye iinaliti, indlela kuphela ngayo ngamava semehlo aphathwe - umsebenzi Injongo ogama iphambili ukuchonga iinyembezi semehlo ezikhoyo kunye nokupheliswa kwayo.

Kwenzeka iqembu semehlo Singafumana na ubudala, kodwa ke kwiimeko ezininzi, esi sifo kwenzeka abantu yobudala abaqolileyo ukusuka kwiminyaka engama-25 ukuya ku-50 abaye ukubona (ukubona), iqondo eliphezulu, kwakunye kwi utyando nobunzi- asebekhulile ukususwa cataract. Imiba yomngcipheko ephambili esi sifo zezi: a ukubona olomeleleyo, ezahlukeneyo yokulimala kwamehlo, yofuzo.

Indlela ephambili unyango kotyando, nto leyo efunekayo lwempumelelo zexesha layo kwakunye njengoko ubukho ixesha elide ngamava semehlo kukhokelela neuronal ukufa kweeseli kunye notshintsho ayibuyiseki umva kwiretina.

Eyona ngoyena usetyenziswa rhoqo iindlela recovery yaxobuka retina ziquka:

1. sclerosing indlela - on umaleko olungaphandle piece iliso indawo kunye kwentsini abicah sponge okanye iplastiki ilastiki eqhotyoshelweyo, nto leyo ethintela ukuyilwa nakujoliso olutsha delamination, kuncitshiswe uxinzelelo retina, kwaye ixhasa izaleko semehlo.
2. Indlela retinopexy womoya - emehlweni zenyuse iqamza lomoya, leyo aya kwisiza delamination kunye neebhloko ngayo, ngaloo ndlela ethintela ulwelo ukuba yande ngaphezulu phantsi retina.

Ngamanye amaxesha ukuze kuzuzwe snuggling epheleleyo looding semehlo kuyimfuneko yokuqhuba izihlandlo eziliqela. Kwimeko apho kwecala ayikhange yachukumisa indawo macular, uqikelelo ukwenzela ukufunyanwa kakhulu babenethemba, kodwa kungenjalo umbono sinesiphene ziya kuhlala ngonaphakade. Ubungqongqo unesiphako uya kuxhomekeka uqina lokhathalelo abanezakhono ejikeleza.

unyango umbala for iinyembezi semehlo kunye nemingxuma okwangoku kwakhokelela wona semehlo: cryotherapy kunye laser photocoagulation ngamanye impembelelo emhlabeni ngu ubushushu okanye ebandayo, nangokurhala iqala apho ngelotha lwenzeka kwaye retina choroid.
