Pakukora uye arambe achirema pamusoro sclera mune dzimwe nzvimbo hakuna chete. Saka kuwanda yekupindurwa chinoratidza rokunze goko wokutanga kungava 0.3-1 mm.

Chokunze paiva pakati sclera

Saka chii sclera? mhando iyi fibrous zvinyama randinogara anoverengeka akaturikidzana. Uyezve, mumwe nomumwe wavo ane pachake zvachiri. The rokunze rukoko unonzi episcleral. Pane vakawanda tsinga kuti anopa ropa kutenderera unhu. Mukuwedzera, kuruvanze rukoko iri vakachengeteka zvakabatana rokunze ziso mugove Kamudzira. Izvi yayo huru chinhu.

Sezvo unorema ngarava ropa inopfuura mberi dhipatimendi optic muviri kuburikidza tsandanyama, rokumusoro chikamu rokunze rukoko rakasiyana dzomunyika kumativi ndichibvunza ropa rive.

The kwakadzama akaturikidzana

The chaizvo chete sclera rinoumbwa kunonyanya kubva fibroblasts uye collagen. zvinoriumba ava zvikuru kuti seboka. Boka zvinhu rokutanga ave achishingaira munyaya nedanho pakuburitswa collagen, uye kuparadzana fibers ayo. Internal, wokupedzisira paiva zvinyama anonzi "shava ndiro." Rine yakawanda ruvara rwacho iyo inouyisa chaiyo Hue ziso.

Nokuti staining ose ndiro dzakadaro kusangana zvimwe masero - chromatophores. Ivo huri yomukati rukoko akawanda. Brown ndiro kunyanya inoumbwa matete fibers ari sclera, uyewo nouipi zviduku kwakavharwa nenyama zvinoriumba. Kunze rukoko urwu akafukidzwa endothelium.

All midziyo ropa uye tsinga harinzwi riri sclera, ichipfuura nhume - chaiwo makwara.

Ko

sclera mabasa vari siyana chaizvo. Wokutanga imhaka ndechokuti collagen fibers zvisina kurongwa munzira yakarongeka mukati tishu. Nokuda kwaizvozvi, chiedza mwaranzi kungoti havakwanisi kupinda napakati sclera. zvinyama ichi anodzivirira the retina kubva zvikuru kuona chiedza uye chiedza chezuva. Nemhaka iyi inoti, munhu anokwanisa kuona zvakanaka. Ndicho chinangwa chikuru pamusoro sclera.

jira iri rakagadzirirwa kudzivirira meso kwete chete kubva zvikuru chiedza, asi kubva ose kukuvara, kusanganisira avo mumuviri uye chisingaperi. Mukuwedzera, sclera anodzivirira ari nhengo zvaakaratidzwa pashamwari dzezvakatipoteredza zvinhu.

Uyewo, tinofanira kutaura rimwezve kushanda tishu. Conventionally, rinogona kunzi chitunha. It sclera chinhu yepamusoro rutsigiro uye panguva imwecheteyo rakavimbika fastening chaikosha nemarunda, tsandanyama, uye zvimwe zvinoumba ziso.

vachiberekwa chirwere

Pasinei zvakanaka nyore mamiriro, pane zvimwe zvirwere uye zvirwere sclera. Usakanganwa kuti jira uyu anoita zvinokosha kushanda, uye chiitiko chipi nyonganyonga Zvinoipisisa basa kuona midziyo yose. The chirwere unogona kuderedza nokuona acuity uye kutungamirira irreparable nemigumisiro. scleral zvirwere havasi chete chokuziva, asi nokuda mikana yakawanda yokukurudzira siyana uye ndakawana hwechimiro.

zvokurwara ichi, zvitema sclera, rinowanzoberekera somugumisiro magene kubatwa uye malformation zviri zvinyama unobva yeziso, achiri mudumbu. Chechienzi mumvuri nokuda diki rukoko ukobvu. Pashure matete membranes kwemaziso sclera translucent ruvara. Zvinokosha kucherechedza kuti zvokurwara ichi zvinowanzoitika nevamwe anomalies ziso, uyewo kutyorwa paumbwe dzinotsanagura nokunzwa, mapfupa uye mapfundo.

Zvirwere sclera iri kazhinji vachiberekwa. Pakati nezvokunetseka uye melasma kwakadaro. With kukura chirwere pamusoro scleral pamusoro mavara rima vari aumba. Varwere vane chirwere chakadaro chinofanira vakanyorwa nechimwe ophthalmologist. With kukura chirwere ichi zvinoda kugara richiona uye nyevero nekukudziridza zvakakomba yematambudziko mangwanani.

vawana zvirwere

Zvakajairika mazuva kuzvimba sclera. Zvirwere kuti kuitika somugumisiro izvi zvakakodzerwa kutarisirwa. Pokumuka zvirwere zvakadai zvinogona musatsamwisa chete mukuru dysfunction vamwe mugadziriro womunhu muviri, asi utachiona. Kazhinji Utachiona zvinopfuura ocular munyama rokunze goko aibuda node kana ropa. Ndiro kukonzera kushoma.

Pamugumo

Zvino kuti munoziva zvakataurwa sclera uye chero chirwere yacho tishu ikoko. Tikaitira zvirwere varo rinotanga chirwere uye zano chiremba wacho. nyanzvi chete anogona mishonga Mabatirwo chirwere nokuda kuziva zvose zviri zviratidzo. With kukura zvirwere sclera inokurudzirwa kubvunza munhu ophthalmologist. Mazvikokota anofanira kutakura kubuda zvinoverengeka mumarabhoritari nemiedzo. ARV ushandiswe pashure kuongorora chirwere.

Kana chirwere anokonzerwa rwakavhunika mamwe enyika muviri, kurapwa nechinangwa kubvisa runotikurudzira chikonzero. Ndipo kutora matanho vadzorere maonero.
