Cudurada dahsoon - isha heterochromia

Heterochromia isha la xiriira xadgudub Avv Midabka ah - melanin. Dadka qaba cudurka this leeyihiin midab kala duwan ee iris ka. hormone Melanotropin in la soo saaray ee qanjirka pituitary ee, galaa dhiigga iyo dheecaanka lafdhabarka, fidaa jirka oo dhan, sidaas sharciyeynta biosynthesis ee melanin ee jirka. Markaas hormoonka hydrolases peptide cytocidal Britain. Sidaa darteed, in ay dhacdo xadgudub biosynthesis ee melanotropin melanin iyo heterophthalmia yeesho. Waa in la sheegay in fiirsashada ee melanin go'aamisa midabka indhaha. iris Color indhaha ula xiriira midabka maqaarka iyo timaha. Waxaa jira laba nooc oo waaweyn oo iris - iftiinka (inta badan buluug-cawlan oo leh midabo kala duwan leh) iyo brown (mugdiga iyo iftiinka brown). Waxa loo sameeyey in ay tahay gabi ahaanba irises isku leeyihiin nooca la mid ah aadanaha kajirin (ie ee deegaamaynta iyo ka-fiirsashada of Midabka).

Heterochromia isha sidoo kale waxay keeni kartaa ka depigmentation. khubaro intooda badan waa dhiiran tahay in ay aaminsan yihiin in depigmentation dhabta ah waxaa la aasaasay oo sabab u ah geeddi-side ee iris ka. factor muhiimka ah ee horumarinta heterochromia indhaha waa hiddo. Xaaladdan oo kale, indhaha ka mid ahaan doonaa aabbihiis ee midabada, iyo labaad - hooyada.

Ha illoobin in heterochromia indhaha yeesho sabab u tahay noocyo kala duwan oo cudurro kala duwan (iritis, glaucoma, siderosis choroidal, dhiigbaxa, iwm). Ugu jaleecada hore, haddii ay taasi ku, ku kala duwan yihiin midabka of iris waxaa loo arkaa mid ka mid ah calaamadaha cad. Si kastaba ha ahaatee, cudurka aasaasiga dhigay in daraasad faahfaahsan oo dheeraad ah.

indhaha Heterochromia kala qaybsan yihiin saddex nooc: secretory, dhamaystiran, dhexe. Muuqaalka caan ku heterochromia secretory waa in labada midabada ay joogaan in iris ah. complete Marka indhaha heterochromia nin midabo kala duwan. Marka heterochromia dhexe iris leedahay in ka badan laba midabo. Isagoo ka hadlayay kuwaas oo, mid u taagan midabka xukuma, la xirrira giraan ah agagaarka ardayga.

Natiijada cilmi-indhaha, waxaa loo sheegay in dadkii laga helay il heterochromia, caadka, iyo cyclites inta badan duubay. Heterochromia siman inta badan labada arkay brunettes mugdi-weershe light-weershe ah timo cad, oo ay leeyihiin. qorayaasha Qaar ka mid ah ku doodayaan in cudurada ay tani tahay weli mid ah bukaanka buluug-weershe badan. Xaaladaha qaarkood, dadka heterochromia calaamadeeyay la carruurnimada hore, kuwa kale - Bukaan-socodka loo ogaado xaqiiqda kaliya ee qaangaarnimada. Heterochromia inta badan laga diiwaangeliyey bukaanka da'doodu u dhaxayso 20 ilaa 45 sanno.

Heterochromia la etiology neurogenic in dhammaan xaaladaha weheliyay shaqada caadiga ah ee indhaha u dhalaalaya, oo aan nooc kasta oo kayd ah oo ku saabsan dusha sare ee wilka, aleelka of hallawda iyo gashto. baaritaan cqaadir ogaado hoos u fiirsashada Midabka stromal indhaha ku kale la barbar dhigo. Xaaladdan oo kale, midabka ah ee iris waa labis in dhammaan qaybaha ay. noocyada Tani waxa lagu gartaa heterochromia joogitaanka paresis dareemayaasha dabacsanaadaan dhinaca halkaas oo iris la discolored ah. Horumarinta heterochromia neurogenic la xiriira caro kordhay ganglion ee afka ilmo-galeenka u dabacsanaadaan. wuxuu leeyahay, dareemayaasha oo saamayn ku horumarka ah iris iyo Midabka. isbedel waxay tilmaamayaan dysfunctionality halis ah in hay'adaha ka mid ah hababka dareemayaasha iyo xididdada dhiigga. Cudurkaan uu yeesho waxbarashada xadgudub albinism iyo Midabka isha mesodermal. Heterochromia ku koobnayn hal il Midabka iris mesodermal. Arin kale ka heterochromia wada cadyahay oo waa in aysan u siin dhibaatooyinka iyo waa qoyska, biosynthesis ku Midabka logu kala dhaxlo ee jirka.
