Vadzidzi dzakasiyana size: zvinokonzera, fungidziro

Vadzidzi vane inosiyana vari kuchengetwa vanhu zvimwe zvirwere ophthalmic uye chetsinga. Mukurapa, asi chiratidzo akaratidza kusaruramisira kwakakura ziso vadzidzi, rinonzi anisocoria. zvokurwara iri kuchengetwa kana kuzotadzira tsitsi fibers ziso chokuita tsandanyama dilates mboni , kana ocular parasympathetic fibers enzvimbo tsandanyama basa aienda pamusoro mudzidzi.

Vadzidzi vane inosiyana, zvinokonzera chirwere

Kana anisocoria ndiwo mugumisiro yokukuvara ziso, umo ukama tsandanyama kuti constricts mboni, mboni pakarepo pashure pokunge zvaitika wokutanga nhete, asi nokukurumidza anowedzera zvakare, uye akarega kuteerera pekugara uye ziso kuitika.

dzimwe nguva vadzidzi kuti inosiyana kunogona kukonzera kuzvimba Iris, inonzi iritis.

Maitiro All kudukupiswa pamwe mudzidzi-kuvhara yemaziso kunobva ischemia Iris. Yemaziso achabatsirwa munhu kuoneka kurwadziwa mukati yeziso, murwere kuona zvishoma nezvishoma shoma.

Kana vadzidzi inosiyana zvikuru kuoneka sechiedza, ichi ndicho angangodaro ari kuratidzwa zvinetso zviri parasympathetic innervation. chirwere ichi chinokonzera dilatation ari mudzidzi (mydriasis) uye zvose zvayo kuita uyewo simba. Kakawanda, mydriasis ndiyo migumisiro kukundwa ari oculomotor etsinga, izvo pamwe chete yakashatiswa mumufambiro squint, yakarambidza injini mashandiro yeziso, ptosis uye diplopia.

Nevamwe vadzidzi vari anisocoria angava nokuda bundu kana aneurysm, compressing ari oculomotor etsinga.

The parasympathetic denervation (vadzidzi vane inosiyana) imhaka ane chirwere kuzvimba ziso kana ziso panosangana kukuvadzwa mune ciliary ganglion.

Panyaya iyi mboni asingadi sei chiedza, asi mano kuderedza pekugara (kuchinja) iri zvabatwa.

Adie syndromes uye Horner

Adie chirwere kunoratidzwa ne chokwadi kuti kana iwe ringabviswa maonero, mboni dilates zvishoma nezvishoma, uye izvi, uyewo, anotyora pekugara, uye akarasikirwa kutarisana acuity. chirwere ichi Kazhinji vakadzi vaduku uye ndicho chikonzero mydriasis ziso rimwe.

Kana anisocoria yakakura murima kana kana iwe kubvisa chiedza, ipapo zviri nyore kuratidzwa anisocoria kana Horner kuti syndrome.

chirwere ichi pamwe chete ptosis, chiso anhidrosis (zvaipesana vangadikitira) uye aienda pamusoro mudzidzi, uye kazhinji mhedzisiro munhu pakaputsika tsitsi innervation ziso. Vadzidzi pana Horner kuti chirwere vanoteerera anowanzoita kuti pekugara uye chiedza.

Mhaka Horner urwere, kenza ndiyo kumusoro zvemapapu, uropi hunde musana lesion kana repamusoro remuromo nomuzongoza. Kana Horner urwere, izvo yakabuda iri pamusoro kenza yemapapu, panguva iyoyo vakachengeta uremu duku tsandanyama kwemaoko, marwadzo zvichiratidza kuti medial pechiso ruoko.

Vadzidzi dzakasiyana kukura vari nemhaka compression pamusoro tsitsi fibers kenza thyroid somugumisiro dzakasiyana-siyana maoparesheni, kunotevera, namamota, rakawedzerwa node nodes zviri pamutsipa, kuti carotid tsinga thrombosis, uye nokuda kwezvimwe zvikonzero.

Kana mugumisiro pfungwa stratified carotid tsinga, Horner chirwere pamwe chiso marwadzo kudivi rimwe, uye kusagadzikana chepfungwa kweropa.

chirwere Horner mune vana rinoita neuroblastoma ari remuromo kana thoracal chikamu.

Kana nyore anisocoria (zvinokosha) Kakawanda chirwere zvishomanana mutsauko kwakakura mboni (kwete kupfuura 0.5 mm).

dzimwe nguva A Kurwisa migraine kungaita yaitsigira divi mydriasis. Vadzidzi dzakasiyana kukura iyi, pane ndevenguva uye mudzidzi maitiro ari zvabatwa chose.

Nevamwe vadzidzi - chikonzero chakakura kunorapwa kwachiremba, sezvo vangada kuva nokuda nezvirwere zvakakomba.
