Mohlolo bolwetse - heterochromia leihlo

Heterochromia leihlo amanang le tlōlo pigment tswakana - melanoma. Batho ba nang le lefu lena ho ba le mebala e sa tšoaneng ea iris e ho. Melanotropin, li-hormone hore e ya hlahiswa ka pituitary tšoelesa, kena maling le mokelikeli cerebrospinal, ata ho pholletsa le 'mele, kahoo a laolang biosynthesis ea melanin' meleng. Ebe Hormone molek'hule cytocidal peptide hydrolases. Ka lebaka leo, tabeng ea tlōlo ea biosynthesis ea melanin melanotropin, le develops heterophthalmia. E lokela ho ile a bolela hore ea mahloriso ea melanin rerang ho mmala ea mahlo. Mala iris e ea mahlo e haufi-ufi amanang le pigmentation letlalo le moriri. Ho na le mefuta e 'meli e ka sehloohong ea iris e - khanya (boholo putsoa-grey le shades tse fapa-fapaneng) le sootho (lefifi le khanya sootho). Ho 'nile ha e thehilweng hore e ka ho feletseng irises tsoanang na le lintho tsa tlhaho e tšoanang batho ha e yo (khr diriswa le mahloriso tsa pigment).

Heterochromia leihlo ka boela hlahe depigmentation. litsebi tse ngata li rata ho lumela hore depigmentation sebele' Ho thehoa ka lebaka la dithulaganyo holofatsang ka iris e ho. Ntlha ea bohlokoa ka ho ntshetsa pele ba mahlo heterochromia ke lefutso. Tabeng ena, leihlo le leng e tla mebala ntate oa hae, 'me ea bobeli -' mè.

Se ke la lebala hore mahlo a heterochromia develops e loketseng ho tse fapa-fapaneng mafu a fapaneng (iritis, glaucoma, choroidal siderosis, tsoa mali, joalo-joalo). Ka chebo ea mahlo, tabeng ena, ho se tšoane ha 'mala oa iris e ho nkoa e mong oa matšoao a clearest. Leha ho le joalo, ka lefu mantlha beha ka ho ithuta boitsebiso bo eketsehileng.

Heterochromia mahlo li arotsoe ka mefuta e meraro: secretory, e feletseng, e bohareng. A tsobotsi bath ya heterochromia secretory ke hore mebala e ba babeli ba teng le ka iris e ho. Ha ka ho feletseng heterochromia mahlo tsa mebala e fapaneng monna. Ha e bohareng heterochromia iris e na le mebala e fetang tse peli. Ha a bua ka eo, e mong o ema 'mala e ka sehloohong, eaba ba etsa lesale pota thaka ea.

Ka lebaka la ho etsa lipatlisiso mahlo, ho ile ha hlokomeloa hore batho ba na le boloetse ba heterochromia leihlo, lera, le cyclites hangata e tlalehiloeng. Heterochromia lekana hangata e hlokometse bobeli leseling-eyed lekhooa, 'me ba le lefifi-eyed brunettes. Ba bang ba bangodi pheha khang ea hore bolwetse ena ke ntse ho feta tloaelehile har'a bakuli putsoa-eyed. Maemong a mang, heterochromia batho tšoailoe ka bongoaneng ba pele, batho ba bang - Bakuli ba fumane hantle 'nete ena feela motho e moholo. Heterochromia hangata e tlalehiloeng ho bakuli ba lilemo li lilemo tse 20 ho ea ho 45.

Heterochromia le neurogenic etiology ka maemong 'ohle a tsamaea le mosebetsi ho tloaelehile ea mahlo e khanyang, e ntle le mofuta ofe kapa ofe mobung holim'a cornea e, clouding tsa vitreous le lense. Nyenyane ho hlahloba ka lemoha fokotseha stromal pigment mahloriso bapisoa le leihlo le leng. Tabeng ena, ho pigmentation ea iris e ke junifomo ka likarolo tsohle tsa lona. mefuta ena e tšoauoa ke boteng heterochromia le kutloelo-bohloko methapo ea kutlo paresis lehlakoreng moo thaka e discolored. Ntshetsopeleng ya neurogenic heterochromia amanang le eketseha teneha ea cervical le kutloelo-bohloko ganglion. Ka tsela eo o ile a re methapo ea kutlo e ama ntshetsopele ya iris e le pigment lona. Liphetoho tsena li bontša hore motho o dysfunctionality tebileng didirisiwa tsa tsamaiso ea methapo ea kutlo le vascular. lefu lena hlaha ka albinism tšebeliso e mpe ea thuto le mesodermal retina pigment. Heterochromia feela leihlo mong mesodermal iris e pigment. phapang e 'ngoe ho tloha albinism heterochromia ke hore e ha e fane ka mathata le ke lelapa, ho lefa anomaly pigment biosynthesis' meleng.
