Mboni - chii ichi? Description, mamiriro, mabasa uye zvinhu. pupillary kwomusikirwo chiedza

Kana chete kwekanguva kuti maziso ako uye edza kurarama murima, unotanga kunzwisisa kuti zvinokosha zvikuru kuti chiono kwevanhu. Ndezvipi vanhu havakwanisi vakafirwa kugona kwavo kuona. Uye kana meso - girazi kwemweya, mboni - ndiwo hwindo edu kunyika.

The nemamiriro ziso

Muviri womunhu ane akaoma Manyiminya hurongwa. Chinangwa charo chikuru - uchatamisa mifananidzo kuburikidza optic etsinga kuuropi.

Yeziso kuva chimiro rinosvika, iri muna muchadenga uye ane nguvo matatu: fibrous, uye retinal vasculature. Inside nayo ndiyo aqueous zvinosetsa, izvo uye vitreous muviri.

White chidimbu yeziso rinosanganisira mucosa (sclera). , Front läpinäkyvä mugove inonzi cornea chinhu Manyiminya izvo ane hombe simba refractive. Pasi ndiro Iris kuti anoita kushanda diaphragm.

Chiedza nekubudisa airatidza kubva chinhu pamusoro anowira kutanga pamusoro cornea uye refracted, ichipfuura mboni pamusoro izvo, riri rimwe biconvex izvo uye anopinda Manyiminya ezvinhu neziso.

Rakatevera pfungwa munzira mufananidzo wavaiona - the retina. Zviri goko masero kuti vane hanya chiedza; asi pasikweya uye matanda. Retin anofukidza yomukati pose ziso uye kuburikidza tsinga fibers kuburikidza optic etsinga transmits mashoko kuuropi. Izvi kunodiwa finite maonero uye kuziva zvaakanga aona.

mboni basa

Pane nevakawanda dimikira vanhu, "kuikoshesa," asi vanhu vashoma nhasi vanoziva kuti Apuro inonzi mboni pamazuva akare. Mashoko aya rinoshandiswa kare uye ndiyo yakanakisisa anoratidza sei tinofanira kubata meso edu - sezvo chinokosha uye zvinodhura.

mboni kwevanhu inotongwa tsandanyama vaviri sphincter uye dilator. Vari neKomisheni akasiyana mapoka tsinga kungova tsitsi uye parasympathetic nehurongwa.

Mboni - iwo, chaizvoizvo, pokupinda napo iro chiedza anopinda the retina. Iye anoita somunhu regulator, tapering mune chiedza uye anowedzera zviri nokushaiwa kwayo. Saka, mboni ziso inodzivirira the retina kubva kutsva uye anovandudza kutarisana acuity.

mydriasis

Zvinoita Norm, kana munhu akawedzera mudzidzi? Zvinoenderana zvinoverengeka pamusoro. Mune zvokurapa kwezvakatipoteredza, zvakadai kutanga anonzi mydriasis.

Zvakaratidza kuti kwete chete vadzidzi vakaitei chiedza. kuwedzera zvavo zvinogona kukonzerwa yaifara kunetsa: kufarira simba (kusanganisira kurara), mufaro, zvisingatsungiririki kurwadziwa kana kutya.

pamusoro apa inokonzera dzinongoitika mydriasis pasina kukanganisa kuona acuity uye ziso utano. Kazhinji, vagumirwe mboni inomhanya, kana mupfungwa kumashure ikadzoka dzose.

Mydriasis Fani maitiro evanhu riri chidhakwa kana marwadzo kudhaka. Uyezve, dilated vadzidzi kazhinji anoratidza zvakakomba chepfu, akadai zvanga zvine utachiona uhu.

Pathological mydriasis kazhinji kunoonekwa varwere zvinorwadza kukuvara pfungwa. Kuramba dilated vadzidzi kunoratidza kuvapo munhu ane vanoverengeka zvichibvira zvirwere:

• yemaziso;
• migraine;
• rutivi rwomuviri ari oculomotor etsinga ;
• encephalopathy;
• thyroid dysfunction;
• Eddie syndrome.

Vanhu vakawanda vanoziva kubva mafirimu kuti vaneta amburenzi vanachiremba kutanga aongororwe maziso. pupillary kwomusikirwo chiedza, uyewo avo saizi anogona kuudza vanachiremba chaizvo. A zvishomanana kuwedzera rinoratidza kudzika kufenda, ukuwo "girazi", anenge maziso matema chiratidzo chakakura chaizvo ezvinhu.

corestenoma

Kutarisira constricted mboni - mamiriro zvinopesana neizvi mydriasis. Ophthalmologists vanouti miosis. kutsauka uyu ane zvikonzero, angava chisingakuvadzi kutarisana rakaremara, asi kazhinji ndiko chikonzero kuona chiremba pakarepo.

Nyanzvi kusiyanisa dzakawanda mhando mioza:

1. Functional, umo aienda imhaka zvoga, dzakadai murombo chiedza, mamiriro hope, mucheche kana kukwegura, hyperopia, nokusevenza zvakapfuuridza.
2. Medical miosis - kugamuchirwa mugumisiro kugadzirira iyo, kuwedzera kumboenda basa, ine zvainoita nokushanda ziso netsandanyama.
3. Akafa mitezo - dzinoratidzwa kwakakwana kana kukwana kushaya gwenya kugona dilator.
4. Miosis kutsamwa - kuchengetwa spasm pamusoro sphincter. Kazhinji kuwanikwa namamota muuropi, yomumuzongoza, encephalitis, uyewo vanhu vachitambura multiple sclerosis netsviyo.
5. Syphilitic chinyamunhari chinorwadza - kunogona kuitika chero pavaipfuura chirwere, kunyange zvazvo nenguva kurapa iri apo neapo.

anisocoria

Maererano nenhamba, ose wechishanu munhu Panyika vadzidzi kuti inosiyana. asymmetry iyi inonzi anisocoria. Kazhinji, misiyano vari kunyora nezvavo uye chete kuonekwa kune ophthalmologist, asi mune dzimwe musiyano inogona kuonekwa chinoabatsira. Mutemo pupillary dhayamita panguva ino chaiyo asynchronously, uye mune zvimwe zviitiko saizi dzakasiyana-siyana chete ziso rimwe, apo mumwe inoramba mira.

Anisocoria anogona kuva nhaka uye akava. Muchiitiko chokutanga, kwakadaro nemamiriro ziso imhaka genetics, rechipiri - yokukuvara kana vamwe chirwere.

Vadzidzi vane diameters siyana zvinowanika vanhu vachitambura kubva zvirwere zvakadai:

• optic kukuvara tsinga;
• aneurysm;
• gumo uropi;
• bundu;
• chetsinga zvirwere.

Policoro

Dual mboni - isingawanzowanikwi muchimiro ziso abnormalities. Izvi yokusafa zvazviri inonzi POLYCOR, dzinoratidzwa maviri kana kupfuura rimwe vadzidzi Iris.

Kune mhando mbiri chirwere ichi: dzenhema uye yechokwadi. Ipfungwa kwenhema zvinoratidza kuti mboni rinovharwa Kamudzira vasiri noruvara, uye zvinoita sokuti yakabvooka shoma. Muchiitiko chino, kwomusikirwo chiedza chiri chipo mune mumwe chete.

POLYCOR True chokuita zvokurwara yacho optic mukombe. Maumbirwe vadzidzi haisi kumativi nguva dzose, pane maburi muchimiro ane denderedzwa, kuderera, mumwe keyhole. Kwomusikirwo chiedza, kunyange asina haana, pane mumwe nomumwe wavo.

Vanhu vane zvokurwara ichi vanonzwa yakawanda kusanzwa, ari chakaremara ziso anoona zvikuru kupfuura dzose. Kana nhamba vevaanodzidzisa mukuru 3, uye vava guru (2 mm kana kupfuura), mwana kusvikira pagore, kungangova kuti kuchengeta kuvhiyiwa. Adults kugadza vachipfeka kwokururamisa kuonana lenses.

zera zvinhu

Vanaamai vakawanda vechiduku kazhinji cherechedzai kuti mwana dilated vadzidzi. Ndinofanira kumutsa nekuda vhunduka ichi? Isolated kacho - havasi ngozi, inogona kukonzerwa murombo chiedza mukamuri uye hunhu kukakavara tsinga. Kuona chitoyi yakanaka kana kutya nokuda unotyisa Barmaley mwana achava reflexively kuwedzera vadzidzi, nokukurumidza vachava shure kune dzose zvakare.

Kana ichi kunoitika nguva dzose - inguva kuridza aramu uye kutsvaka nechimbichimbi kurapwa. Izvi zvingaratidza chetsinga zvirwere, uye imwe zano nyanzvi haisiri kukuvara.

pupillary pakarambwa chiedza kuchinja zera. In kuyaruka, pane vaifanira zvichibvira uyewo, kusiyana vakuru vanhu, riri kuramba constricted vadzidzi - hwandaiva musiyano.
