Bakuman kudwala - heterochromia diso

Heterochromia diso kugwirizana ndi kuphwanya pigment kaphatikizidwe - melanin. Anthu ndi matenda ali mumtundu wa Iris lapansi. Melanotropin timadzi kuti amapangidwa mu pituitary England, alowa m'magazi ndi madzimadzi cerebrospinal, kufalikira thupi lonse, motero malamulo a biosynthesis wa melanin mu thupi. Ndiye timadzi molekyulu cytocidal peputayidi hydrolases. Choncho, vuto la kuphwanya biosynthesis wa melanin melanotropin ndipo akufotokozera heterophthalmia. Izo ziyenera kuti anthu ambiri melanin ndiyo mtundu wa maso. Mtundu Iris cha maso ndi yogwirizana mtundu ndi tsitsi. Pali mitundu iwiri waukulu Iris - kuwala (makamaka buluu imvi ndi mithunzi zosiyanasiyana) ndi zofiirira (mdima ndi kuunika bulauni). Pali umboni kuti ali mwamtheradi irises zofanana ndi umunthu kulibe (mwachitsanzo, kutanthauzira ndi ndende ya pigment).

Heterochromia diso akhoza n'chiyani depigmentation. Akatswiri ambiri okonda amakhulupirira kuti depigmentation weniweni aumbike chifukwa cha njira osachiritsika mu Iris lapansi. Chinthu chofunika kwambiri pa chitukuko cha maso heterochromia ndi chibadwa. Pankhaniyi, diso limodzi adzakhala mitundu bambo ake, ndipo chachiwiri - mayi.

Musaiwale kuti maso heterochromia akufotokozera chifukwa zosiyanasiyana matenda osiyana (iritis, khungu, choroidal siderosis, magazi, etc.). Koyamba, mu nkhani iyi, kusiyana mtundu wa Iris ndi chimodzi cha zizindikiro momveka. Komabe, matenda zofunika kukhala phunziro mwatsatanetsatane.

Heterochromia maso anawagawa mitundu itatu: secretory wonse, chapakati. Mbali khalidwe la heterochromia secretory ndi kuti mitundu iwiri alipo mu Iris lapansi. Pamene wathunthu heterochromia maso a mitundu yosiyanasiyana munthu. Pamene chapakati heterochromia Iris ali mitundu oposa awiri. Ponena za amene aliyense akuimirira mtundu wamphamvu, kupanga mphete mozungulira mwana wa.

Chifukwa cha kafukufuku ophthalmic, izo inafotokoza kuti anthu anapezeka ndi heterochromia diso, maso, ndi cyclites zambiri olembedwa. Heterochromia mofanana zambiri anati onse mu kuwala eyed tsitsi, ndipo ndi mdima-eyed brunettes. Ena Olemba kudwala izi komabe ambiri pakati pa odwala maso a buluu. Nthawi zina, heterochromia anthu amalembedwa ndi ana aang'ono, ena - Odwala kutsimikizira mfundo imeneyi okha mukadzakula. Heterochromia zambiri olembedwa odwala zaka 20 kuti 45.

Heterochromia ndi neurogenic etiology milandu onse limodzi ndi ntchito wabwinobwino wa maso owala, popanda mtundu uliwonse madipoziti padziko diso la, clouding wa vitreous ndi mandala. Tosaoneka Kupenda wapezeka kuchepa stromal pigment ndende poyerekeza ndi diso ena. Mu nkhani iyi, mtundu wa Iris ndi yunifolomu ziwalo zake zonse. mtundu wofanana ndi kukhalapo heterochromia wachifundo mitsempha paresis kumbali komwe Iris ndi discolored. Development wa neurogenic heterochromia kucheza ndi anthu irritability wa khomo lachiberekero wachifundo ganglion. Choncho anati mitsempha kumakhudzanso Kukula kwa Iris ndi pigment ake. kusintha zikuonetsa dysfunctionality kwambiri za zida za machitidwe mantha ndi mtima. matenda akufotokozera mu alubino nkhanza maphunziro ndi mesodermal retinal pigment. Heterochromia okha diso limodzi mesodermal Iris pigment. Kusiyana kwina kwa alubino heterochromia ndi kuti sapereka mavuto ndipo ndi banja, kumtundu anomaly pigment biosynthesis mu thupi.
