M Pathology - heterochromia ido

Heterochromia ido hade da pigment kira take hakkin - melanin. Mutane da wannan cuta da launi daban-daban na Iris. Melanotropin hormone da aka samar a cikin pituitary gland shine yake, shiga cikin jini, kuma cerebrospinal ruwa, shimfidawa a ko'ina cikin jiki, haka gudãnar da biosynthesis na melanin a cikin jiki. Sa'an nan hormone kwayoyin cytocidal peptide hydrolases. Saboda haka, idan akwai take hakkin da biosynthesis na melanin melanotropin kuma tasowa heterophthalmia. Ya kamata a ce cewa taro na melanin kayyade launi da idanu. Launi Iris na idanu ne a hankali alaka fata pigmentation da kuma gashi. Akwai biyu main iri Iris - haske (kagaggun blue-m tare da daban-daban inuwõyinta suna kusa,) da kuma ruwan kasa (dark da haske launin ruwan kasa). An tabbatar da cewa shi ne cikakken m irises da wannan dabi'ar mutum ba ya zama (watau sarrafawa da kuma maida hankali pigment).

Heterochromia ido kuma iya haifar da daga depigmentation. Mai masana suna karkata zuwa imani da cewa real depigmentation aka kafa a sakamakon degenerative matakai a cikin Iris. An muhimmanci factor a ci gaba da idanu heterochromia ne gadar hali. A wannan yanayin, wanda ido zai zama mahaifinsa launuka, kuma na biyu - da mahaifiyarsa.

Kada ka manta da cewa idanu heterochromia tasowa saboda wani iri-iri daban-daban cututtuka (iritis, glaucoma, choroidal siderosis, zubar da jini, da dai sauransu). A duban farko, a wannan yanayin, bambanci a launi na Iris an dauki daya daga cikin mafi tsabta bayyanar cututtuka. Duk da haka, da ainihin cutar kafa a cikin wani karin cikakken nazari.

Heterochromia idanu ya kasu kashi uku iri: secretory, complete, tsakiyar. A halayyar alama na secretory heterochromia ne cewa biyu launuka ne ba a cikin Iris. Lokacin da cikakken heterochromia idanu na launi daban-daban mutumin. Lokacin da tsakiyar heterochromia Iris yana da fiye da biyu launuka. Magana wadda, daya tsaye rinjaye launi, forming wani zobe kusa da almajiri.

A sakamakon ophthalmic bincike, an lura da cewa, mutane kamu da heterochromia ido, cataracts, kuma sau da yawa rubuta cyclites. Heterochromia daidai sau da yawa lura biyu a cikin haske-sa ido m, kuma suna da duhu-sa ido brunettes. Wasu marubuta gardamar cewa wannan Pathology ne har yanzu more kowa daga blue-sa ido marasa lafiya. A wasu lokuta, heterochromia mutane alama tare da farkon yara, wasu - Marasa lafiya binciki wannan al'amari kawai a adulthood. Heterochromia sau da yawa na rubuce a cikin marasa lafiya shekaru 20 zuwa shekaru 45.

Heterochromia da neurogenic etiology a duk lokuta tare da al'ada aiki na mai haske da idanu, ba tare da wani irin adibas a farfajiya na cornea, clouding na vitreous da ruwan tabarau. Microscopic jarrabawa gano rage stromal pigment maida hankali idan aka kwatanta da sauran ido. A wannan yanayin, da pigmentation na Iris ne uniform a duk sassanta. Wannan nau'in shi ne halin gaban heterochromia m jijiya paresis a gefe inda da Iris ne discolored. Development of neurogenic heterochromia hade tare da ƙara irritability na mahaifa m ganglion. Kamar wancan ce jijiya rinjayar da ci gaban da Iris da pigment. Wadannan canje-canje nuna wani tsanani dysfunctionality a cikin na'ura na juyayi da kuma jijiyoyin bugun gini tsarin. Wannan cuta tasowa a zabiya zagi da ilimi da kuma mesodermal retinal pigment. Heterochromia iyakance zuwa daya ido mesodermal Iris pigment. Wani bambanci daga zabiya heterochromia ne cewa shi ba ya bayar da rikitarwa da kuma ne iyali, da hereditary anomaly pigment biosynthesis a cikin jiki.
