Chii uye sei kuziva kumanikidzwa muziso? Norma ziso nevezera.

The mvura riri pamberi mukamuri, neshure mukamuri, uyewo munzvimbo vitreous muviri yeziso, ane kumanikidza pamusoro pamadziro ziso. Tichifunga nezvokuti zvose makamuri vari uninsulated in, vachikurukura mumwe kuburikidza pupillary yokutanga uye rwemberi kamuri dzakaparadzaniswa chete aida kuchinja chaizvo chiputu Zinn vitreous. Naizvozvo, kana kumanikidzwa mu izvi in vatatu vakasiyana, musiyano iri kukurumidza dzichienderana. Izvi zvose zvinoratidza chimwe ziso mhango akazadzwa intraocular zvokunwa. The kumanikidzwa iyo mvura rokufamba pamusoro ziso porusvingo, rinonzi intraocular kana TENSO ziso, i.e. ocular ake.

Ocular kumanikidzwa, mwero izvo anosarudza nhamba pakati vachikwanisa yeziso uye chitsama zviri hungasiyana chimwe masikati, uye hazvizorevi zvokurwara. BP ine simba guru matangiro yakadaro kwakakura sezvo ocular kumanikidzwa. Normal arterial matauriro ari 120/80 yemaminitsi mmHg. Art. Izvi imhaka zvakajairika midziyo kuti uvake muviri ziso. Zvisinei, zvakakwana panofananidzwa BP uye ocular mupfungwa kuti rokumusoro wokutanga kukosha, dzakanga uye wechipiri, kwete. Ziso kumanikidzwa, izvo dzinosiyana mwero 18 kusvika 24 mm HG. v., kuti pamwero mukuru tisingatungamirirwi. Izvi imhaka yokuti dzemo nevezera ropa iri nhengo anozvipira yaidzorwa uye haisi nguva dzose noku nemidziyo makuru. In maziso chakakombama chaizvo nzira kutungamirira midziyo, uye avo vashomashoma saizi kunyevenutsa kumanikidzwa kufamba kweropa wave. Ukuwo, vashomanana makuru venous hunde dzacho hwezvekukurukurirana zvikuru water drainage ropa kubva ziso, zvichivhiringidza paumbwe ichi mamiriro venous stasis. Pane chimwe chinhu zvinova zvinoderedza zvikuru kwokudzvinyirira kwomunhu BP iri ziso, ndiko - the osmotic kumanikidzwa ropa mapuroteni zvikamu zviduku.

Sezvataurwa pamusoro apa, pane nokufamba nezuva iro rine ocular neBP, mwero oscillation amplitude kwakadaro hakuiti kupfuudza 3-5 mm HG miniti. Art. Zvose zvinopfuura zvezvinotaurwa ichi richinzi yakaderera kana mukuru ziso nevezera. Uyu pathological ezvinhu. kuchinja wokutanga anonzi hypotension kana yakaderera BP, uye wechipiri - neBP, yemaziso. Tensa ziso inogona tsunga nehasha nokuda digitaalinen kuongororwa, uyewo uchibatsirwa anokosha mano, akadai ane tonometer kuna Maklakov. Kana intraocular kumanikidzwa nokuyerwa ocular tonometer kare vanofanira anesthetize ziso, kubva ari mudziyo pachaiswa zvakananga pamusoro cornea, ndoupiko unonyanya vasanonoka chikamu muviri kwete chete kuona, asiwo yose muviri. Nokuti Kuvimbika neziso rimwe akabvisa mumwe ivhu shoma. Kufunga kuisa kure nokushandisa chaiyo madhayi zvinogadzirisa sirivha-kwakavakirwa (colloid sirivha) kana zvimwe zvinhu. Nokuti kugadzira nzvimbo Data rupawo, akasiya nokuda cornea weziso, rinoshandiswa mapepa, kare akapusika pamwe donje wetted nedoro. The mufananidzo inofanira kupiwa kuti dziome kwazvo, kuitira kuti kuzora. Zvadaro, chaiyo mutsetse anosarudza pachiyero intraocular kumanikidzwa. The maduku munda, avo kunoreva ophthalmotonus kumusoro, uye, Ukuwo, vanowana zvinowanikwawo pamusika rupawo, ziso kufurirwa dererei. Panguva ino pachikuva, pane yamunenge nzira kuona intraocular kumanikidzwa Somuenzaniso, asiri kuonana tonometry. Zvisinei, nokudyidzana nzira richiri kushanda chaizvo uye, Chikurukuru, inoshanda nzira kuyera tensor maziso.

Kana akawanikwa yakakwirira kwevari ziso kumanikidzwa, kuitisa hwakadzama kuongororwa, izvo zvinosanganisira nezuva zvichiongororwa yavo. Kana wakaiswa zvachose dzakakwirira ophthalmotonus ipapo chirwere yemaziso. Kunogona kukonzera zvishoma nezvishoma kurasikirwa wezvakaonekwa. Kuitira kudzivisa zvachose upofu, murwere mukuru kumanikidzwa muziso (sei kurapa kunogona kuona bedzi nyanzvi) kunoda nokukurumidza uye wakakwana norudaviro ziso, yevasungwa uye kushivirira.
