Disinsertion semehlo

iqembu semehlo yinkqubo iliso zophendlo lwezifo apho kwiretina ngenxa yesizathu esithile zisuswe ukusuka choroid. Oonobangela looding semehlo zizinto ezahlukeneyo, kuquka yokulimala kwamehlo, retinopathy seswekile, ubani angakwazi kwiretina kunye nangezilonda intraocular.

Lidla ngamava semehlo kukhokelela ukuhla okubonakalayo kwizinga umbono. Unobangela olukhawulezileyo izifo ziba discontinuities retina. Kwimeko komsipha kolwelo semehlo vitreous seeping phantsi retina kwaye eyohlula esingxotyeni. iinyembezi semehlo oludla ngokwenzeka xa utshintsho kubume kunye nokwakhiwa umzimba vitreous (ukwanda lexinene iziyobisi kunye nophuhliso ezintambo abaqhagamshelwe kunye retina). Xa uhambisa iliso retina imisonto ukugqabhuza, ebangela ombane kumphezulu wayo kwaye kunokukhokelela iqhuma.

iqembu semehlo na iimpawu isici. ukufikelela ngexesha zamehlo ngexesha kuphuhliso mpawu zilandelayo ziya kukunceda ukuba ugcine umbono:

1. Imbonakalo komkhusane phambi kwamehlo. Amaxesha amaninzi, izigulane musa ziwuthathele ingqalelo lo mba yaye akukho ungxamile ukuya kugqirha, ukwenza self-unyango. Ukuba kukho isigqubuthelo phambi kwamehlo, ukuze ukhumbule ukuba ngubani oqale uphuhliso iimpawu, ukususela ngexesha esithumela oyingcali, kuthatha yonke intsimi ngayo.
2. ukukhanya original ukukhanya (ngokohlobo iintlantsi, nemibane). izenzakalo enjalo aphela rhoqo zibonisa inkqubo ibutho retina kwaye umqondiso ukuba utyelelo ngokukhawuleza zamehlo.
3. Le deformation izinto kunye nokulahleka kwimimandla yabo ngamnye wentsimi umbono, uhlaba oonobumba kunye neenamba. uphawu uthe ibonisa ezimashakeleyo central zone retina.

Nceda uqaphele ukuba lo wona libutho semehlo akukho amathontsi okanye iinaliti ngayo. ngoncedo kule ngezifo ukuze adityaniswe (ngamanye amazwi, ukuhlanganiswa iindlela ezahlukeneyo), kodwa ngokuyimfuneko kubandakanya unyango ngotyando looding semehlo. Ukuze umbono wabuyiselwa kangangoko inkulu kunokwenzeka kufuneka ibe utyando ophthalmologic ezintsonkothileyo kwenziwa ngokukhawuleza kangangoko kunokwenzeka. ukukrala ezingapheliyo izakhiwo iso zingenzeka kwiimeko obuphambili sifo. Kwezinye iimeko, ngamava semehlo iphela ziimfama.

Kuba impumelelo unyango semehlo wona eye Ugqirha kuqala kufuneka ayinakubhaqa ikhefu semehlo, uze ukubusiphula. Ngexesha ukusebenza kwindawo isikhewu kwebala ngokuzenzela generated nangokurhala, ibangela loloyiko, sivumele isithuba ukuba kutywinwe imiphetho. zobugcisa zale mihla ikuvumela ukuba ukunyanga ngamava semehlo ngu laser okanye cryotherapy (ukungakhuseleki ebandayo).

bungabonakala Ezi ndlela zilandelayo olufanayo unyango zoqhaqho le emoyeni:

• ukuzaliswa rotary okanye iindawo ingxaki wengingqi kwindawo retina komsipha;
• Vitrectomy, okt kokususa le zendalo vitreous replacement ngezinto ezenziwe ziyafana iimpawu zabo;
• Laser coagulation - kobudala zoqhaqho kummandla umsantsa encediswa a laser umqadi zonyango.

Lokhuseleko okanye ubhaqo looding semehlo yokuqala siyakukhuthaza ukuba kutyelela zamehlo. Ixesha elichithwa uphethwe uya ukuchonga isifo kunye nokuqhuba ngonyango kunye ngeendlela engephi. ukulimala retina angasoloko ukuthintelwa ngokubona iimfuno zokhuseleko ezingundoqo ekhaya yaye umdlalo, kwakunye imigaqo yokhuseleko ilandelayo ngelixa esenza umsebenzi umsebenzi.
