i-heterochromia Akusona isimo sokuvimbela ukubona. Ayisongeli impilo. Ukwelashwa kungase kudingeke kuphela uma kuwuphawu lwezinye izifo.

Yiziphi izinhlobo ze-heterochromia?

Abathathu uhlobo lwe-heterochromia nakhu:

I-heterochromia ephelele: i-heterochromia iridium Obeye aziwe njengo. Amehlo amabili anemibala ehlukene. Enye ifana nokuluhlaza okunsundu...lapha i-heterochromia ephelele isibonelo;

I-heterochromia eyingxenye: I-Heterochromia iridi Obeye aziwe njengo. Iningi le-iris linombala ohlukile kwelinye iso. Ingakhula esweni elilodwa noma womabili. Kubonakala njengendawo engavamile esweni. Isicelo i-heterochromia ehlukene isibonelo;

Umbala wamehlo unqunywa ukuminyana kwe-melanin ku-iris. Kunezici eziningana zofuzo nezokuphila ezingathinta ukuminyana kwalesi sombala futhi zibangele izinguquko kumbala wamehlo.

Ngokocwaningo oluthile, ukuguqulwa kwesakhi sofuzo esiza ekunqumeni ukusatshalaliswa kwe-melanin ku-8-HTP (hydroxyl tryptophan) indlela, i-heterochromia kungani kungaba njalo. Lokhu kwenzeka lapho ingane ithola ufuzo kubo bobabili abazali. 

Ikhona kusukela ekuzalweni noma ekukhuleni ngokushesha ngemva kokuzalwa i-heterochromiaye i-heterochromia yokuzalwa ubizwa. Lokhu kwenzeka ngenxa ye-syndromes ehlukahlukene, njenge: 

• I-Sturge-Weber syndrome

okwenzeka ezigabeni zakamuva zempilo i-heterochromiadla, wathola i-heterochromia ubizwa. Kuvela ngenxa yezizathu ezilandelayo:

• ukuhlukumezeka kwamehlo
• ukulimala kwamehlo
• Ukungena kwe-melanocytic (isabalalisa iris nevus noma melanoma).
• Izinkinga zamehlo ngenxa yomzimba wangaphandle.
• I-Hypo- noma i-hyper-pigmentation yeso elilodwa.
• I-Latanoprost
• Ukuvuvukala nokopha emehlweni
• eminye imithi ye-glaucoma
• Ukuba khona kwezimila ezimbi neziyingozi ku-iris. 
• I-Chediak-Higashi syndrome
• Isifo sikashukela.

Yiziphi izimpawu ze-heterochromia?

Izimpawu ze-heterochromia Kuyinto kanje:

• Umehluko wombala phakathi kwamehlo amabili. 
• Ukuvuvukala kwamehlo.

• Okunye umehluko wemibala.

I-heterochromia ibonakala kanjani?

• i-heterochromia, ngenxa yomehluko obonakalayo wamehlo, ibonakala ngokubheka.
• i-heterochromiakuba sobala ngaphansi kwezimo ezithile zokukhanya noma lapho uthatha izithombe.
• i-heterochromiaUma lesi sifo sibangelwa isifo esibangela izimpawu futhi sithinta izinga lokuphila, udokotela uzohlola ngokucophelela. Uma kuwufuzo, angase atuse ukuhlolwa kofuzo noma igazi.

Yelashwa kanjani i-heterochromia?

i-heterochromia Abantu abagula ngengqondo badinga ukwelashwa lapho isimo sithinta izimpilo zabo. Uma zingekho izimpawu futhi ingekho imbangela ewumsuka, ukwelashwa kungase kungadingeki.

Izindlela zokwelapha i-heterochromiaezinye zazo yilezi:

• Ukusebenza: Uma kukhona i-cyst ku-iris, ukuhlinzwa kuyindlela yalokhu.
