Ophthalmology: kev puas tsuaj rau lub qhov muag vitreous

Vitreous yog ib tug pob tshab gel uas nyob rau kab noj hniav ntawm cov ceev ceev thiab yog nyob qab lub lens. Sab nraum no nws yog surrounded los ntawm ib tug membrane hauv yog muab faib ua raws (paths). Yog hais tias muaj yog thinning, wrinkling los yog detachment ntawm lub gel, ces tham txog cov DST ob lub qhov muag.

Yuav ua li cas yog nws?

Lub rov tshwm sim los ntawm ntau yam zoo, me me los yog turbidity nyob rau hauv lub vitreous lom zem qhia degenerative dab. Cov feem ntau thiaj paub hais tias pathologies nyob rau hauv uas lub thaj chaw ntawm qhov nruab nrab yog hloov.

Feem ntau, nws yog pob tshab, tab sis muaj tshwj xeeb xov - fibrils. Nyob rau hauv lub hnub nyoog-kev hloov, los yog vim tej yam kab mob, lawv ua tsawg elastic, thiab tej zaum yuav lov, ua rau ib tug deterioration nyob rau hauv lub zeem muag. Nyob rau tib lub sij hawm npaj floater qhov muag. Nws yuav tsum tau muab sau tseg hais tias xws li kev ua txhaum tsis yooj yim rau txoj kev kho, thiab puas hloov nyob rau hauv cov neeg laus yog luag tsis kho (lawv tsuas qeeb thaum tsim nyog txoj kev kho).

etiology

Feem ntau, cov floater qhov muag ua rau uas yuav ua tau heev ntau haiv neeg, yog ib lub txim ntawm cov neeg kho tshuab kev puas tsuaj rau lub qhov muag, haus luam yeeb, siv yeeb tshuaj, los yog nyias muaj nyias ib cov tshuaj. Nyiaj kuj pathological kev hloov uas txuam nrog rau tej yam ntuj tso laus txheej txheem. Nyob rau hauv tas li ntawd, lub xub ntiag ntawm luv luv-sightedness, thaum raug heev thiab nquag kev nyuaj siab nyob rau hauv lub nruab nrog cev uas tsis pom kev zoo, hlab hlwb shocks kuj tsim floater qhov muag.

Yog hais tias koj qhia kom meej rau etiological yam, nws tseem yog muaj nqis mentioning dystrophy los yog o nyob rau hauv lub retina, lub cev qaug, retinopathy txhab ntawm lub choroid, metabolic kev hloov nyob rau hauv lub ceev ceev.

Nws yog ib qho tseem ceeb yuav tau nco ntsoov hais tias tus ntse puas hloov tej zaum yuav precursors ntawm retinal detachment, nyob rau hauv uas muaj tiav thiab irreversible tsis pom, yog li raws sij hawm tswv yim ntawm ib tug ophthalmologist yog yuav tsum tau.

Cov yam ntxwv ntawm tug kev hloov ntawm lub vitreous

Thaum tsim nws xaus, ces, raws li ib tug txoj cai, pathological kev hloov tau cai nyob rau hauv lub central chaw. Periphery ntawm lub vitreous lub cev yog tsis tau hloov. Nyob rau hauv feem ntau tus neeg mob, voids raug tsim uas yog lawm ua tus sau los ntawm hais thiab fibers khoom coagulation. Tsis tas li ntawd, tej zaum yuav muaj bands los yog films, uas ntab dawb nyob rau hauv lub liquefied nruab nrab los yog txuas mus rau hauv qab ntawm lub qhov muag, uas ua rau yus mus rau ib tug ntse pathological kev hloov ntawm view.

Cov kev puas tsuaj rau lub qhov muag vitreous lub cev nyob rau hauv lub loj tshaj plaws manifestation - yog nws shrinkage. Nws yog nrog los ntawm nro vitreoretinal tebchaw uas nyob rau hauv kev mob loj coj mus photopsias, retinal los kua muag, tsos ntawm hemorrhages nyob rau hauv lub vitreous lub cev.

Nws yuav tsum tau muab sau tseg hais tias xws li puas hloov yooj yim mus ntes rau ib tug me me swb. Diagnosing teeb meem siv cov kev soj ntsuam txoj kev tshawb nrhiav no nyuaj heev thiab yuav tsum tau ib tug ntau ntawm kev kho mob kev.

soj ntsuam ces

Thaum tsim floater, cov tsos mob ntawm tus mob tej zaum yuav muaj xws li tsos ua ntej lub qhov muag ntawm tag nrho cov hom ntawm floating hais, uas ua ntau hnov thaum xaiv cov monochrome qhov chaw - dawb phab ntsa, daus thiab ntuj. Cov neeg mob yuav tau noj peb caug qhov muag plooj. Nws tshwm sim vim cov refraction ntawm lub teeb hloov, dhau los ntawm tus kho qhov muag system ntawm lub qhov muag, thiab yog txuam nrog ib tug nco tus duab ntxoov ntxoo rau lub retina, uas thiaj li muaj qhov zoo, thiab tej zaum yuav qhia ntau loj qhov muag puas. Zoo nyob rau hauv kev nkag mus rau ib tug kws kho mob yuav ua kom tiav tsis pom.

Ntaus fibrils ntawm vitreous tsuab zoo li tus neeg mob, me ntsis, threads los yog films uas ho tsis tau visibility, thiab tsiv mus nyob nrog lub qhov muag taw.

Nws yuav tsum tau muab sau tseg hais tias ib tug ntawm feem ntau yog vim li cas rau kev kho mob rau ib tug ophthalmologist yog ib tug tsis txaus siab txog cov tsos ntawm "ya yoov" nyob rau hauv pem hauv ntej ntawm lub qhov muag, los ntawm uas nws tsis yooj yim sua kom tshem tau ntawm. Tom qab cov kev tshawb fawb qhia nws floater.

A cov tsos mob ntawm lub "golden nag"

Tej zaum cov neeg mob uas mus rau tus kws kho mob, kws kho qhov muag, kev tsis txaus siab ntawm golden sparks nyob rau hauv lub qhov muag taw. Qhov twg lawv tuaj los ntawm?

Kev cov kab mob ntawm ntau yam kabmob (e.g., raum, siab thiab endocrine qog) ua rau muaj kev cuam tshuam ntawm metabolic dab thiab ua rau kev hloov colloid lub cev thiab mineral muaj pes tsawg leeg. Qhov no kuj siv rau cov vitreous lub cev, uas tsim pathological kev hloov thiab lub zos dab yog nag lossis daus thiab coagulation, thiab kuj muaj yog ib deposition ntawm cov muaju uas nws qhov ntev yog me me - tsawg tshaj li 0.05 hli.

Cov deposits yog hu ua synchisis scinlillans. Lawv muaj xws li mas ntawm roj los yog tyrosine, noog nyob rau hauv lub liquefied vitreous lub cev nyob rau hauv loj tus xov tooj, thiab pendulum oscillate nrog qhov muag taw pib txim taws thiab ci, uas predetermines ib cov tsos mob ntawm lub "golden nag", uas yog ib tug tsis tshua daim ntawv ntawm kev puas tsuaj, yuav ua rau tus neeg mob mus nrhiav kev kho mob pab.

diagnostics

Kev puas tsuaj ntawm cov vitreous qhov muag kuaj tau los ntawm technically yooj yim manipulation - ophthalmoscopy. Nyob rau hauv filamentous puas hloov kuaj optically npliag kab noj hniav, uas muaj rau hauv daim ntawv ntawm ntsug slits los yog ntau daim. Lub pem hauv ntej phaj ntawm tus ciaj ciam ntawm lub vitreous lub cev tsis muaj kev hloov, tab sis cia li tom qab nws koj yuav saib tau lub grey-dawb fibers. Tej zaum lawv yuav muaj ntau thickness thiab sag nyob rau hauv daim ntawv ntawm cov hlua.

Yog hais tias lub pathological kev loj zuj zus, lub hais voids hauj lwm ua ke los tsim ib tug tib kab noj hniav. Qhov no yog nrog los ntawm kev puas tsuaj ntawm cov vitreous qauv. Thaum ophthalmoscopy yuav pom tawg tsam ntawm fibrils threads. Yog hais tias turbidity yog nyob ze ntawm lub retina, nws yog heev yooj yim mus saib (txawm nyob rau hauv loj qhov ntau thiab tsawg).

Kuv yuav tsum hais tias cov kev hloov no yog feem ntau pom muaj nyob rau hauv cov neeg laus, thiab nyob rau hauv cov neeg mob uas tshuaj mob nyob rau tib lub sij hawm siab myopia los yog degenerative txhab ntawm Internal qhov muag week.

pharmacological txoj kev kho

Txawm tias muaj tseeb tias cov tshuaj (Ophthalmology, xws li) nyob rau hauv ib theem siab, muaj yog tsis muaj txhais tau tias zoo rau hnub tim uas yuav tau ceeb toom kev puas tsuaj ntawm cov vitreous fibrils los yog pab rau cov disappearance ntawm twb puas tsuaj lawm. Feem ntau ntawm cov tshuaj uas cov kws kho rau kev puas tsuaj tiv thaiv kev vam meej ntawm pathological kev hloov. Nws yuav tsum yog li ntawd yuav ceev faj ntawm cov tshuaj, uas nws manufacturers hais tias lawv cov khoom yuav kho tau DST.

Feem ntau, topically thov instillation ntawm cov 2% poov tshuaj iodide los yog ib tug 3% neeg sawv cev "Emoksipin" uas yog txhaj parabulbarly. Rau qhov ncauj thawj coj raug absorbable npaj, piv txwv li, "Vobenzim" los yog "Traumel C". Nyob rau hauv tas li ntawd, cov neeg mob yuav tsum tau mus yauv ib chav kawm ntawm vitamin txoj kev kho. Yog li, lub DST ob lub qhov muag uas tau txais kev kho mob yuav tsum muaj xws li ascorbic acid thiab vitamins ntawm pab pawg neeg B.

Yog hais tias tsim nyog, yuav tsum muab physiotherapy - electrophoresis Lydasum thiab ultrasound txoj kev kho.

laser kev kho mob

Rau hnub tim, nws tau ua nce nrov laser manipulation, uas nyob rau DST yog qhov zoo tshaj rau txoj kev puas tsuaj ntawm floaters. Tej kev kho mob yog tsawg kawg tus, tab sis yuav tsum tau siab txawj ntse thiab kev professionalism ntawm tus kws kho mob. Nws muab rau cov kev puas tsuaj ntawm cov laser opaque tawg tsam mus rau hauv lub vitreous lub cev, uas zom rau hauv me me hais uas tsis muaj kev cuam tshuam tsis pom kev.

Laser kev pab vitreous hu ua vitreolysis. Nws yuav muaj xws li ib qho kev txiav vitreorogovichnyh adhesions. Yog hais tias koj tsim lub zos hernia ntawm lub vitreous lub cev, uas ua rau deformation ntawm tus menyuam kawm ntawv thiab cov kev tso chaw kawm ntawm lub intraocular lens yog ua excision ntawm cov feem ntawm PT. Nyob rau hauv cov ntaub ntawv no, siv ib tug yag laser. mem tes zog khaws ib lub zuj zus (los ntawm 1.5 mus 8.0 mj). Lub lag luam txoj kev vam meej nyob rau hauv lub viscosity thiab transparency ntawm lub vitreous lom zem, thiab taws kub nnyiab ya ntawm ntau thiab tsawg pab.

operative txoj kev kho

qhov muag vitreous kev puas tsuaj kev kho mob ntawm ib tug phais txoj kev hu ua vitrectomy. Qhov no txoj kev kho yuav lub feem los sis tag kev tshem tawm ntawm lub CT, uas yog ua ntawm ib tug vitrectomy system muaj vitreotoma (txiav lub cuab tam) thiab endo-illuminator.

Nyob rau hauv tej rooj plaub, vitrectomy yog siv? Raws li ib tug txoj cai, nws yog nqa tawm nyob rau vitreous puas tsuaj los ntawm qhib kev raug mob, thaum turbidity, raws li zoo raws li hemorrhage thiab retinopathy.

Lub caij ntawm lub lag luam no yog los ntawm 30 mus rau 90 feeb. Calibration yog ua li cas nyob rau hauv lub zos los sis ua kom tsaug zog, tej zaum yuav muaj ib tug los yog ntau tshaj theem, nyob ntawm seb cov theem thiab hom ntawm pathology.

thov dag polymers, thiab kuas ntsev dlaws hloov vitreous. Nyob rau hauv feem ntau tus neeg mob, cov tshuaj ua kua perfluoroorganic tshuaj, gases, los yog silicone cov roj. Tej kev hloov ntawm lub vitreous yuav tsum ua raws li tshab li sai tau, uas tsim nyog viscosity thiab refractive lub hwj chim. Nws kuj tsis muaj rau succumb mus rau lub resorption los yog ua tshuaj lom, inflammatory los yog tsis haum cov tshuaj tiv thaiv.

Tom qab lub lag luam, cov neeg mob yuav tsum tau mus soj ntsuam los ntawm ib tug ophthalmologist, txwv lub cev thiab kev loads, cia li hloov nyob rau hauv kub. Txwv tsis pub ib tug muaj feem mob inflammatory mob pheej rov qab ua haemorrhages, cataracts, siab intraocular siab los yog retinal vascular occlusions.
