Mhedziso

Open-angle glaucoma ndiyo inonyanya kuzivikanwa glaucoma. Glaucoma chirwere chinokuvadza maziso ako uye chinogona kukonzera kudzikisira kuona uye kunyange kupofomara.

Glaucoma inokanganisa zvinopfuura zvepasirese. Icho chiri chikonzero chinotungamira chekupofumara kusingachinjiki.

Yakavharwa-kona (kana kona-kuvhara) glaucoma inogadzira glaucoma kesi muUnited States. Kazhinji zvinonyanya kuomarara pane yakavhurika-kona glaucoma.

Mamiriro ezvinhu ese ari maviri anosanganisira shanduko muziso inodzivirira kukweva kwakaringana kwemvura. Izvi zvinotungamira mukuwedzera kwekumanikidza mukati meziso, izvo zvinokuvadza zvishoma nezvishoma yako optic nerve.

Glaucoma haigone kurapwa. Asi nekutanga kuongororwa uye kurapwa, kazhinji kesi dze glaucoma dzinogona kugoneswa kudzivirira chirwere kubva mukufambira mberi kusvika kukuvara kwekuona.

Glaucoma kazhinji hairatidzi zviratidzo isati yakonzeresa kukuona kwako. Ndicho chikonzero chimwe chakakosha kuti ugare uine bvunzo dzemaziso dzinoongorora glaucoma.

Yakavhurika- vs. yakavharwa-angle glaucoma

Chikamu chepamberi cheziso rako, pakati pecnene uye lens, chakazara nemvura inoyerera inonzi aqueous humor. Iko kusetsa kwemvura:


  • inochengetedza iyo idenderedzwa chimiro cheziso
  • inovaka zvimiro zvemukati zveziso

Nyowani nyowani inosetsa iri kugara ichiburitswa uye ndokuzoburitswa kunze kweziso. Kuti uchengetedze kumanikidza kwakakodzera mukati meziso, huwandu hwakagadzirwa uye huwandu hwakaburitswa hunofanirwa kuchengetwa zvakaenzana

Glaucoma inosanganisira kukanganisa kune zvivakwa zvinobvumidza iyo inosetsa kuseka kubuda. Kune zvivakwa zviviri zvemvura inonwisa mvura yekudonha:

  • iyo trabecular meshwork
  • kubuda kwemukoko

Zvivakwa zvese zviri padhuze nepamberi kweziso, kuseri kwekona.

Musiyano uripo pakati peakavhurika-kona uye yakavharwa-angle glaucoma zvinoenderana nekuti ndeipi nzira mbiri dzemvura dzakakuvara.

In glaucoma yakavhurika, iyo trabecular meshwork inopa yakawedzera kupokana ne fluid kubuda. Izvi zvinokonzera kumanikidza kuvaka mukati meziso rako.

In yakavharwa-angle glaucoma, zvese iyo uveoscleral drain uye iyo trabecular meshwork inozovharwa. Kazhinji, izvi zvinokonzereswa nerisiti yakakuvadzwa (chikamu chine ruvara cheziso) ichivharira chokubuda.


Kuvharirwa kwechimwe chezvitoro izvi kunotungamira mukuwedzera kwekumanikidza mukati meziso rako. Iko kushushikana kwemvura mukati meziso rako kunozivikanwa se intraocular pressure (IOP).

Misiyano mukona

Iyo kona iri mumhando yeglaucoma inoreva iyo kona iyo iris inogadzira nekona.

Mune yakavhurika-angle glaucoma, iyo iris iri munzvimbo chaiyo, uye iyo uveoscleral drainage migero yakajeka. Asi meshwork yetrabecular haisi kunyura zvakanaka.

Mune yakavharwa-angle glaucoma, iyo iris inosvinwa ichipesana nekona, ichivhara iyo uveoscleral draina uye iyo trabecular meshwork.

Zviratidzo zveakavhurika-angle glaucoma

Glaucoma mumatanho ekutanga kazhinji haigadzire chero zviratidzo.Kukuvara kwechiratidzo chako kunogona kuitika usati wazviziva. Kana zviratidzo zvikaonekwa, zvinogona kusanganisira:

  • kuderedzwa kuona uye kurasikirwa kwemaonero ekuona
  • kuzvimba kana kubhururuka cornea
  • kudzikira kwemudzidzi kune saizi yepakati isingashanduke nekuwedzera kana kudzikira kwechiedza
  • kutsvuka mumuchena weziso
  • kusvotwa

Zviratidzo izvi zvinonyanya kuoneka mune yakaoma kesi yeakavharwa-angle glaucoma asi inogona zvakare kuoneka yakavhurika-angle glaucoma. Rangarira, kusavapo kwezviratidzo hakusi humbowo hwekuti hauna glaucoma.


Zvinokonzera open-angle glaucoma

Glaucoma inoitika kana kuvharika kwenzvimbo dzekubudisira mvura yemvura inosetsa kuchikonzera kumanikidza muziso kuvaka. Iyo yepamusoro yemvura inomanikidza inogona kukanganisa iyo optic nerve. Apa ndipo panopinda chikamu chetsinga inonzi retinal ganglion inopinda kumashure kweziso rako.

Hazvina kunyatsonzwisiswa nei vamwe vanhu vachiwana glaucoma uye vamwe vasina. Humwe hunhu hunove hwakaonekwa, asi idzi nhoroondo dzese dzeglaucoma kesi.

Glaucoma inogona kukonzerwa nekushungurudzika kune ziso. Izvi zvinonzi glaucoma yechipiri.

Njodzi zvinhu

Yakavhurika-angle glaucoma inomiririra kesi dzeglaucoma muUnited States. Njodzi zvinhu zvinosanganisira:

  • kukwegura (kumwe kuongorora kwakaratidza kuti glaucoma yakavhurika-glaucoma inokanganisa gumi muzana yevakura kupfuura makumi manomwe neshanu muzana muzana yeavo vakura kupfuura makumi mana)
  • nhoroondo yemhuri ye glaucoma
  • Dzinza reAfrica
  • pedyo-kuona
  • yakakwirira IOP
  • kuderera kweropa (asi kukwidza BP kunotakura dzimwe njodzi)
  • kushandiswa kwemusoro wekorticosteroids
  • kuzvimba
  • bundu

Kuongororwa kweakavhurika-angle glaucoma

IOP yepamusoro inogona kuperekedza glaucoma, asi hachisi chiratidzo chechokwadi. Muchokwadi, chevanhu vane glaucoma vane zvakajairika IOP.

Kuti uone kana iwe uine glaucoma, iwe unoda kuongororwa kwakazara kwemaziso nemaziso ako akawedzeredzwa. Mimwe yemiedzo ichashandiswa nachiremba wako ndeiyi:

  • Kuona zvakanakabvunzo nechati yeziso.
  • Wakaonekwa munda bvunzo kutarisa maonero ako ekunze. Izvi zvinogona kubatsira kusimbisa kuongororwa, asi akawanda semasero ari mumashure eretinal ganglion maseru anogona kurasikirwa mushure mekurasikirwa kunoratidzwa mune yekuyedza munda bvunzo.
  • Dilated ziso bvunzo. Uyu unogona kunge uri muyedzo wakakosha kwazvo. Madonhwe anoshandiswa kuwedzera (kuvhura) vadzidzi vako kuti vabvumire chiremba wako kuti aone mu retina uye neptic nerve kumashure kweziso. Vanozoshandisa chimbo chakakosha chinonzi ophthalmoscope. Maitiro acho haarwadzi, asi iwe unogona kunge wakadzima kuona-kumusoro uye nekunzwisisa kune yakajeka mwenje kwemaawa mashoma.

  • Kurapa kweglaucoma yakavhurika

    Kuderedza kumanikidzwa kwemvura mukati meziso rako ndiyo chete nzira yakaratidza yekurapa glaucoma. Kurapa kunowanzo kutanga nemadonhwe, anozivikanwa semadonhwe e hypotensive, kubatsira kubatsira kudzikisira.

    Chiremba wako anoshandisa ako ekutanga kumanikidza mazinga (kana aripo) kuti aone tarisiro yekumanikidza kuti unyatso kurapa glaucoma yako. Kazhinji, vanozovavarira kumanikidza sechinangwa chekutanga. Chinangwa chinodzikiswa kana chiono chako chikaramba chichiwedzera kana kana chiremba wako achiona shanduko mumutsipa wemaziso.

    Mutsara wekutanga wekumanikidza-kudzikisa zvinodhaka ndeye prostaglandin analogs. Prostaglandins ane mafuta acids anowanikwa mune chero nyama. Vanoita kusimudzira kuyerera kweropa uye kwemuviri wemvura uye nekuvandudza dhiraini yemvura inosetsa kuburikidza neveveoscleral outlet. Izvi zvinotorwa kamwechete husiku.

    Prostaglandins ine mashoma mhedzisiro, asi anogona kukonzera:

    • kukwirisa uye kusviba kwemaziso
    • akatsvuka kana akatsvuka maziso
    • kurasikirwa kwemafuta kwakakomberedza maziso (periorbital mafuta)
    • kusviba kweiri iris kana ganda rakakomberedza ziso

    Zvinodhaka zvinoshandiswa semutsara wechipiri wekudzivirira zvinosanganisira:

    • carbonic anhydrase inhibitors
    • beta-blockers
    • alpha agonists
    • cholinergic agonists

    Mamwe marapirwo

    • Inosarudza laser trabeculoplasty (SLT). Iyi ndiyo nzira yehofisi umo laser inovavarira kune trabecular meshwork yekuvandudza iyo drainage uye yezasi kumanikidza kwemaziso. Paavhareji, inogona kudzikisa kumanikidza ne20 kusvika makumi matatu muzana. Inobudirira mune vangangoita makumi masere muzana yevanhu. Mhedzisiro yacho inotora kubva pamakore matatu kusvika mashanu uye inogona kudzokororwa. SLT iri kutsiva eyedrops mune zvimwe zviitiko.

    • Maonero eakavhurika-angle glaucoma

      Iko hakuna kurapwa kweakavhurika-kona glaucoma, asi kutanga kuongororwa kunogona kukubatsira kuti udzivise yakawanda yenjodzi dzekurasikirwa kwekuona.

      Kunyangwe nemishonga mitsva ye laser uye kuvhiya, glaucoma inoda kuongororwa kweupenyu hwese. Asi eyedrops uye nyowani marapirwo eraser anogona kuita glaucoma manejimendi zvakajairwa.

      Kudzivirira yakavhurika-angle glaucoma

      Kuona nyanzvi yemaziso kamwe chete pagore ndiko kudzivirira kwakanyanya kweakavhurika-angla glaucoma. Kana glaucoma ikakurumidza kuonekwa, mhedzisiro yacho inogona kudzivirirwa.

      Open-angle glaucoma hairatidzi zviratidzo mumatanho ekutanga, saka ongororo dzemaziso nguva dzose ndiyo chete nzira yekuziva kana iri kukura. Zvakanakisisa kuve nekuongororwa kweziso ne ophthalmoscope uye kuwedzera kunoitwa kamwe chete pagore, kunyanya kana iwe uchidarika makumi mana.

      Nepo kudya kwakanaka uye mararamire ane hutano kunogona kupa dziviriro, haisi vimbiso yekurwisa glaucoma.
