heterochromia Asiyomeko yokuthintela ukubona. Ayisongeli kwimpilo. Unyango lunokufuneka kuphela xa luphawu lwezinye izifo.

Ziziphi iintlobo ze-heterochromia?

Bhabha uhlobo lwe-heterochromia Nantsi lapho:

Gqibezela i-heterochromia: heterochromia iridium Kwaziwa njenge. Amehlo amabini anemibala eyahlukileyo. Enye ifana noluhlaza omdaka…apha heterochromia ngokupheleleyo umzekelo;

I-heterochromia engaphelelanga: Heterochromia iridis Kwaziwa njenge Uninzi lwe-iris lunemibala eyahlukileyo kwelinye iliso. Inokukhula kwiliso elinye okanye omabini. Kubonakala njengendawo engaqhelekanga kwiliso. Isicelo i-heterochromia eyahlukanayo umzekelo;

Umbala wamehlo unqunywe ngubuninzi be-melanin kwi-iris. Kukho izinto ezininzi zofuzo kunye nezomzimba ezinokuchaphazela ukuxinana kwesi pigment kwaye zibangele utshintsho kumbala wamehlo.

Ngokutsho kolunye uphononongo, uguquko kwijini enceda ukumisela ukuhanjiswa kwe-melanin kwi-8-HTP (hydroxyl tryptophan) indlela, heterochromia kutheni inokuba njalo. Oku kwenzeka xa umntwana efumana imizila yemfuza kubazali bobabini. 

Yibakho ukususela ekuzalweni okanye ekuphuhliseni ngokukhawuleza emva kokuzalwa heterochromiaye i-heterochromia yokuzalwa ibizwa. Kwenzeka ngenxa yee-syndromes ezininzi ezahlukeneyo ezifana:

• Isifo seBloch-Sulzberger
• isifo Bourneville.

okwenzeka kumanqanaba okugqibela obomi heterochromiayitya, ufumana i-heterochromia ibizwa. Ivela ngenxa yezi zizathu zilandelayo:

• ukwenzakala kwamehlo
• ukwenzakala kwamehlo
• Ukungena kwe-melanocytic (ukusabalalisa iris nevus okanye i-melanoma).
• Iingxaki zamehlo ngenxa yomzimba wasemzini.
• I-Hypo- okanye i-hyper-pigmentation yeliso elinye.
• Ilatanoprost
• Ukudumba nokopha emehlweni
• amanye amayeza eglaucoma
• Ubukho be-benign and malignant tumors kwi-iris. 
• I-Chediak-Higashi syndrome
• Isifo seswekile.

Ziziphi iimpawu ze-heterochromia?

Ifumaneka njani i-heterochromia?

• heterochromia, ngenxa yokwahlukana okubonakalayo kwamehlo, ichongiwe ngokujonga.
• heterochromiaibonakala phantsi kweemeko ezithile zokukhanya okanye xa ifota.
• heterochromiaUkuba isifo sibangelwa sisifo esibangela iimpawu kwaye sichaphazela umgangatho wobomi, ugqirha uya kuqhuba uviwo olunzulu. Ukuba lufuzo, unokucebisa uvavanyo lwemfuza okanye lwegazi.

Iphathwa njani i-heterochromia?

heterochromia Abantu abagula ngengqondo bafuna unyango xa imeko ichaphazela ubomi babo. Ukuba akukho zimpawu kwaye akukho sizathu sisisiseko, unyango lusenokungabi yimfuneko.
