Chiyani komanso mmene kudziwa kuthamanga diso? Norma diso kuthamanga.

The madzi limene lili mu chipinda kutsogolo, kumbuyo chipinda, komanso mu thupi vitreous wa mwana wa diso, ali ndi kuthamanga pa khoma la diso. Poganizira kuti zipinda onse uninsulated mphako, iwo tilankhule wina ndi mnzake mwa pupillary kutsegula ndi chipinda kumbuyo ankasiyana chabe mtolo kusintha kwambiri Zinn vitreous. Choncho, ngati kuthamanga mu cavities awa atatu osiyana, kusiyana yatsala limagwirizana. Zonsezi zikusonyeza limodzi diso M'mimbamo wodzazidwa ndi madzi intraocular. Kuthamanga imene madzi ochitachita pa khoma diso, wotchedwa intraocular kapena TENSO diso, i.e. ocular wake.

Ocular kuthamanga, mlingo wa amene amasankha chiŵerengero pakati pa mphamvu ya mwana wa m'diso la ndi kuchuluka kwa nkhani zimachitika mosiyana masana, ndipo sadzatero kudwala. magazi ali ndi chikoka chachikulu pa chiyambi chikuperekedwa monga ocular kuthamanga. Normal wolumikizira kamvekedwe ndi 120/80 mphindi mmHg. Art. Ichi ndi chifukwa zipangizo wamba amene kuyamwitsa diso. Komabe, wathunthu kufanana pakati pa magazi ndi ocular m'njira yakuti apamwamba phindu woyamba, apamwamba ndi chachiwiri, palibe. Diso kuthamanga, amene zimasiyanasiyana mlingo wa 18 ndi 24 mamilimita Hg. v., Pamlingo waukulu paokha. Ichi ndi chifukwa chakuti m'dera kuthamanga magazi mu ziwalo wodzilamulira malamulo ndipo si nthawi zonse ikufanana sitima zazikulu. Pamaso pa njira tortuous kwambiri kutsogolera ziwiya, kukula ochepa pansi kuthamanga zimachitika yoweyula. Komano, ochepa makungwa lalikulu venous kwambiri facilitates outflow wa magazi kwa diso, inhibiting mapangidwe nyumba imeneyi venous stasis. Pali chinthu china chimene kwambiri kuchepetsa kuthamanga kwa magazi mu diso, ndi - kuthamanga osmotic wa tuzigawo twa magazi mapuloteni.

Monga taonera, pali tsiku kusinthasintha amene ali ocular oopsa, mlingo wa totere oscillation matalikidwe si upambana 3-5 mamilimita Hg yokha. Art. Chirichonse kosaoneka ukulu uwu limanenedwa ngati otsika kapena mkulu diso kuthamanga. Ichi ndi chikhalidwe pathological. Kusintha woyamba amatchedwa hypotension kapena chipsyinjo otsika magazi, ndipo chachiwiri - matenda oopsa, khungu. Tensa diso zingadziŵike ziri mwa Kupenda digito, komanso ndi thandizo la zipangizo zapadera monga munthu tonometer wa Maklakov. Pamene intraocular kuthamanga muyeso wa tonometer ocular poyamba ayenera anesthetize diso, kuyambira chida adzaikidwa mwachindunji pa diso, ndilo gawo yovuta kwambiri kwa thupi osati kuona, komanso lonse chamoyo. Pakuti kudalirika ndi diso limodzi kuchotsedwa ndi zitsanzo zochepa. Kuzilingalira nyamukani ndi ntchito njira yapadera utoto siliva ofotokoza (colloid siliva) kapena zinthu zina. Pakuti kukonza amaonekera malo deta kumanzere ndi diso la diso, umagwiritsidwa ntchito pepala, poyamba kuwapukuta ndi thonje wasambitsa ndi mowa. chithunzi laperekedwa kuti ziume bwinobwino, kuti dzola mafuta. Kenako, mzere wapadera Mzimuyo mlingo wa kuthamanga intraocular. The kuchepera munda, zimenezi ophthalmotonus pamwamba, ndipo Kwenikweni onse pamsika amaonekera, diso kuthamanga n'chozama. Pa gawo lino, pali njira yabwino kwambiri kudziwa kuthamanga intraocular Mwachitsanzo, si kukhudzana tonometry. Komabe, njira kukhudzana akadali zogwirizana kwambiri ndi, Chofunika kwambiri, njira kuyeza tensor maso.

Ngati anapeza mpweya wambiri wa diso kuthamanga, kuchititsa tinafotokoza mwatsatanetsatane, womwenso polojekiti wawo. Ngati kalekale atathana ophthalmotonus okwera ndiye anapezeka ndi glaucoma. Zimenezi zingachititse kuti imfa mwapang'onopang'ono masomphenya. Pofuna kupewa khungu, wodwalayo kuthamanga diso (mmene tiyenera kuchitira izo angathe kudziwa yekha ndi katswiri a) ungabwere mwamsanga ndi chokwanira zimene diso, ndende ndi kuleza mtima.
