Ophthalmology: lapho kubhujiswa lesi Vitreous iso

Vitreous kuyinto gel okusobala ukuthi igcwalisa ngalo ingaphakathi of yeso futhi itholakala ngemuva lens. Ngaphandle lizungezwe ulwelwesi ngaphakathi ihlukaniswe yaba iziteshi (izindlela). Uma kukhona is thinning, ukuba nemibimbi noma lamabutho ka ijeli, bese ucoca ngaloko emehlweni DST.

Kuyini lokhu?

Ukuvela ukuma ahlukahlukene, usayizi noma turbidity ku amahlaya Vitreous kusikisela izinqubo esiwohlozayo. The njalo kunazo kutholakale ukuthi une pathologies lapho izakhiwo medium kwashintsha.

Ngokuvamile, kuba esobala, kodwa iqukethe ekhethekile ngentambo - fibrils. Ngo izinguquko ezihlobene nokukhula, noma ngenxa izifo ezithile, ziba ngaphansi nokunwebeka, futhi zingase zephule, okuholela a ukuwohloka embonweni. Ngesikhathi esifanayo eba iso floater. Kufanele kuqashelwe ukuthi ukuphulwa enjalo kunzima yokwelapha, kanye nezinguquko elimazayo kwasebekhulile cishe hhayi ziphathwe (bangakwazi kuphela ukubambezela lapho kufaneleka yokwelapha).

omsakazo

Ngokuvamile, izimbangela floater iso okungaba zahlukahlukene kakhulu, is phetho umonakalo mechanical iso, ukubhema, ukudla izidakamizwa noma imithi ehlukile. Izimali nazo izinguquko sokugembula elihlobene ne yemvelo inqubo yokuguga. Ngaphezu kwalokho, ukuba khona esifushane okwesa-, lapho zihlatshwa ukucindezeleka isikhathi eside futhi njalo phezu izinhlaka umbono, nerve uthuthumele ingase futhi ukuthuthukisa floater iso.

Uma ucacise izici etiological, liphinde Kuhle kokusho sokuwohloka noma ukuvuvukala kwe-retina, ukukhathala ngokomzimba, izilonda retinopathy we choroid, izinguquko umzimba e yeso.

Kubalulekile ukukhumbula ukuthi izinguquko abukhali elimazayo ingase ibe kokumethemba lamabutho ngwengwzi, lapho kukhona ukulahleka ephelele futhi engelapheki umbono, ngakho iseluleko esifike kudokotela wezifo zamehlo Kuphoqelekile.

Izimpawu izinguquko ebhubhisayo Vitreous

Uma kwenziwa noma usuhlakazekile ke, njengoba umthetho, izinguquko sokugembula babonakala ezindaweni ezimaphakathi. Azungeze umzimba Vitreous aliguquki. Ezimweni eziningi, voids akhiwa zazo zigcwele by izinhlayiya yemisipha imikhiqizo coagulation. Futhi, kungase kube bands noma amafilimu, okuyinto ukuntanta ngokukhululekile medium kuncibilike noma exhunywe phansi iso, okuholela izinguquko abukhali sokugembula umbono.

Ukubhujiswa iso umzimba Vitreous e ukubonakaliswa olunzima - kuyinto ukuncipha yayo. It kuhambisana ukungezwani compounds vitreoretinal ukuthi ekuholeni ezinzima ukuze photopsias, izinyembezi ngwengwzi, ukubukeka nokopha emzimbeni Vitreous.

Kufanele kuqashelwe ukuthi ushintsho olunjalo elimazayo kulula ukubona aku-slide encanyana. Ukuhlonza Ukugula izinkinga besebenzisa izindlela zokwelashwa uphenyo kunzima kakhulu futhi lidinga ukuba abanolwazi kwezokwelapha.

ukubonakaliswa emitholampilo

Uma kwenziwa floater, izimpawu iziyaluyalu ingase ihlanganise ukubukeka phambi kwamehlo azo zonke izinhlobo izakhi elintantayo, okuyinto babe esikufezile lapho sicabangela isikhala ezinombala ofanayo - white walls, liqhwa nezikhatha esibhakabhakeni. Iziguli zingenza futhi ukugubha esilufifi. It kuvela ngenxa kwalungiswa izinkunga zokubona izinguquko ukukhanya, edabula uhlelo optical we iso, futhi lihlotshaniswa ithunzi iconsi kuyi-retina, lapho kukhona kunciphisa izinga, futhi zingase zibe Indlela zikhubazeke ngaphezulu iso. Ukwephuza ukufinyelela udokotela kungaholela ukuqedela ukulahlekelwa umbono.

fibrils Ohlukunyezwayo of izikhwebu Vitreous kubonakale nesineke, izindawo, izindikimba noma amafilimu okuyinto kakhulu konakalise ukubonakala, futhi siqhubekele nalezi ukunyakaza iso.

Kufanele kuqashelwe ukuthi esinye sezizathu ezijwayeleke kakhulu ukwelashwa kudokotela wezifo zamehlo ukukhononda mayelana nokubonakala "Yizimpukane flying" phambi kwamehlo, okuyindawo akunakwenzeka ukuqeda. Ngemva survey olufanele uyibonise floater.

A uphawu "imvula osemqoka"

Ngezinye izikhathi iziguli abaya kudokotela, udokotela wamehlo, esekhala izinhlansi segolide ngaphansi ukunyakaza iso. abazange Nivelaphi?

izifo Functional kwezitho ezihlukahlukene (isib, izinso, isibindi kanye endocrine nezindlala) kuholele ukuphazamiseka izinqubo umzimba futhi kubangele izinguquko Colloid lomzimba nokumbiwa kwengoma. Lokhu kusebenza futhi umzimba Vitreous, okuyinto ukuthuthukisa izinguquko sokugembula nezinqubo lwendawo kwezulu kanye coagulation, futhi kukhona sebethule zinhlayiya kabani Ubukhulu ezincane - esingaphansi 0.05 mm.

Lezi ezifakwa abizwa ngokuthi synchisis scinlillans. Zakhiwa ikakhulu cholesterol noma tyrosine, buthelela ku uketshezi emzimbeni Vitreous ngamanani amakhulu, futhi pendulum oscillate ngeso ukunyakaza uqale ziyakhazimula futhi libalele, okuyinto predetermines uphawu "imvula osemqoka", elisho ezingavamile yokubhubha, okubangela isiguli ukuba afune usizo lwezokwelapha ukusiza.

ukuhlola

Ukubhujiswa iso Vitreous ukutholwa zokukhwabanisa ngobuchwepheshe elula - ophthalmoscopy. Ngo izinguquko filamentous elimazayo kutholwa ingaphakathi optically ezingenalutho, okuyinto isimo izimbotshana mpo noma ezihlukile. Ngaphambili ipuleti emdeni umzimba Vitreous ngaphandle kwezinguquko ezithile, kodwa nje ngemva kwaso ungabona kwezintambo zesivikelo sesifuba empungana. Bangaba ukujiya ezahlukene kanye ehle efomini enezintambo.

Uma inqubo sokugembula iqhubeka, imigodi okukhulunywa uhlangane ukwakha umgodi owodwa. Lokhu kuhambisana ukubhujiswa isakhiwo Vitreous. Lapho ophthalmoscopy kungabonwa izinsalela fibrils izindikimba. Uma turbidity iseduze retina, kunzima ngempela ukubona (ngisho osayizi enkulu).

Mangisho ukuthi lezi zinguquko zivame kakhulu otholakala abagugile ezigulini uxilongwe ngesikhathi esifanayo myopia okusezingeni eliphezulu noma izilonda esiwohlozayo iso ulwelwesi lwangaphakathi.

ukwelashwa kwemithi

Naphezu kweqiniso lokuthi umuthi (zamehlo, kuhlanganise) ezingeni eliphezulu, akukho izindlela ezisebenzayo usuku ukuthi ngabe waxwayisa lapho kubhujiswa lesi fibrils Vitreous noma nomthelela ukunyamalala sele atjhabalalise. Iningi izidakamizwa ukuthi kuyabekwa ukubhujiswa nje kuphela ukuvimbela ukuqhubeka izinguquko sokugembula. Ngakho-ke kufanele uqaphele izidakamizwa, abazidumbu zabo abakhiqizi zithi imikhiqizo yabo elaphe DST.

Ngokuvamile, ihlelwe ngokulandelana kwezihloko isicelo instillation 2% potassium iodide noma umenzeli 3% "Emoksipin" ukuthi injected parabulbarly. Ukuze abaphathi temlomo babelwa amalungiselelo absorbable, isibonelo, "Vobenzim" noma "Traumel C". Ngaphezu kwalokho, iziguli belulekwa ukuba ibhekane Yiqiniso yokwelapha Vitamin. Ngakho, emehlweni DST kokuthola ukwelashwa kufanele kufake ascorbic acid namavithamini yeqembu B.

Uma kudingekile, ingasatshenziswa Physiotherapy - electrophoresis Lydasum futhi ukwelashwa ultrasound.

ukwelashwa laser

Kuze kube manje, sekuvame ethandwa laser zokukhwabanisa, ngaleso DST kukhona ephumelela kunazo kukho ukubhubha ezintantayo. Impatho enjalo kancane koda, kodwa kudinga nemakhono lasetulu nobuchwepheshe bale udokotela. Uhlinzeka lapho kubhujiswa lesi laser izingcezwana opaque emzimbeni Vitreous, okuyinto sokudiliza ku izinhlayiya ezincane ukuthi musa kuthinte umbono.

kokungenela Laser Vitreous ngokuthi vitreolysis. Lungase luhlanganise a ukuvuvukala cut vitreorogovichnyh. Uma usuqala hernia endawo umzimba Vitreous, okuyinto abangela ukusonteka of umfundi kanye nokubekwa okungafanele lens intraocular senziwa excision we ingxenye efanele PT. Kulokhu, sebenzisa laser YAG. ishayela amandla abelethwe ngamunye (kusukela 1.5 kuya 8.0 MJ). impumelelo Ukusebenza kuxhomeke viscosity futhi obala amahlaya Vitreous, futhi ufasimbe ezinobukhulu.

ukwelashwa op

iso ukwelashwa ekubhujisweni Vitreous esikhombisa indlela yokuhlinza okuthiwa vitrectomy. Lokhu yokwelapha ihilela ukususwa esinqunyiwe noma ephelele CT, esiqhutshwa nge uhlelo vitrectomy ehlanganisa vitreotoma (ukusika ithuluzi) futhi Endo-lwenkanyiso.

Kwezinye izimo, vitrectomy isetshenziswa? Njengomthetho, it is eyenziwa ngaleso umonakalo Vitreous yokulimala evulekile, lapho turbidity, kanye ukopha futhi retinopathy.

Isikhathi msebenzi kusukela imizuzu engu-30 kuya kwangu-90. Isilawuli Samandla kwenziwa ngaphansi izinzwa wendawo noma jikelele, kungase kudingeke izigaba eyodwa noma ngaphezulu, kuye ngokuthi isiphi isigaba kanye nohlobo zokugula.

isicelo polymers yokufakelwa, futhi olinganiselayo usawoti izixazululo esikhundleni Vitreous. Ezimweni eziningi, ukuthatha ketshezi izinto perfluoroorganic, amagesi noma uwoyela abicah. Noma yimuphi esikhundleni Vitreous kumele kube sicaca, nge viscosity ezifanele namandla yezokubona. Iphinde akanayo ukuba sinqotshwe resorption noma kubangele ukuphendula anobuthi, ukuvuvukala noma nomzimba.

Ngemva kokuhlinzwa, iziguli belulekwa ukuba kubuka kudokotela wezifo zamehlo, nomkhawulo imithwalo ngokomzimba futhi ezibukwayo, ngokuphazima kweso lapho izinga lokushisa. Kungenjalo kwengozi yokuthola ukuvuvukala okuphindaphindiwe haemorrhages, ale nkinga, ophezulu intraocular noma ngwengwzi occlusions semithambo.
