Umbono - ubumpumputhe ebusuku

Ubumpumputhe basebusuku ukungaboni kahle ebusuku noma ekukhanyeni okuncane.

Ubumpumputhe basebusuku bungadala izinkinga ngokushayela ebusuku. Abantu abanobumpumputhe ebusuku bavame ukuba nenkinga yokubona izinkanyezi ngobusuku obucwathile noma ukuhamba egumbini elimnyama, njengethiyetha yaseshashalazini.

Lezi zinkinga zivame ukuba zimbi kakhulu ngemuva nje kokuba umuntu esendaweni ekhanyayo. Amacala amaMilder angahle abe nesikhathi esinzima ukuzivumelanisa nobumnyama.

Izimbangela zobumpumputhe basebusuku ziwela ezigabeni ezi-2: ziyelapheka futhi azilapheki.

Izimbangela ezelaphekayo:

• Isifo senkwethu
• Ukubona eduze
• Ukusetshenziswa kwemithi ethile
• Ukushoda kukavithamini A (kuyaqabukela)

Izimbangela ezingalapheki:

• Ukukhubazeka kokuzalwa, ikakhulukazi ukungaboni kobusuku obumile bokuzalwa
• I-retinitis pigmentosa

Thatha izinyathelo zokuphepha ukuvimbela izingozi ezindaweni zokukhanya okuphansi. Gwema ukushayela imoto ebusuku, ngaphandle uma uthola imvume kudokotela wamehlo akho.

Izithako ze-Vitamin A zingasiza uma unenkinga kavithamini A. Buza umhlinzeki wakho wezempilo ukuthi kufanele uthathe malini, ngoba kungenzeka ukuthi uthathe kakhulu.

Kubalulekile ukuthi uhlolwe ngokuphelele ukuze kutholakale imbangela, okungenzeka ukuthi iyelapheka. Shayela udokotela wamehlo akho uma izimpawu zokungaboni ebusuku ziqhubeka noma zithinta kakhulu impilo yakho.

Umhlinzeki wakho uzokuhlola wena namehlo akho. Inhloso yokuhlolwa kwezokwelapha ukuthola ukuthi inkinga ingalungiswa yini (ngokwesibonelo, ngezibuko ezintsha noma ukukhishwa kwe-cataract), noma uma inkinga ingenxa yento ethile engalapheki.

Umhlinzeki angakubuza imibuzo, kufaka phakathi:

• Bunzima kangakanani ubumpumputhe basebusuku?
• Zaqala nini izimpawu zakho?
• Ingabe kwenzeka ngokuzumayo noma kancane kancane?
• Ingabe kwenzeka ngaso sonke isikhathi?
• Ingabe ukusebenzisa amalensi okulungisa kuthuthukisa ukubona kwasebusuku?
• Wake wahlinzwa iso?
• Yimiphi imithi oyisebenzisayo?
• Kunjani ukudla kwakho?
• Ngabe usanda kulimaza amehlo noma ikhanda lakho?
• Unomlando womndeni wesifo sikashukela?
• Ingabe unezinye izinguquko zombono?
• Yiziphi ezinye izimpawu onazo?
• Ingabe unengcindezi engajwayelekile, ukukhathazeka, noma ukwesaba ubumnyama?

Ukuhlolwa kwamehlo kuzobandakanya:

• Ukuhlolwa kombono wombala
• I-reflex light yomfundi
• Ukuhlehlisa
• Ukuhlolwa kwe-retinal
• Sika ukuhlolwa kwelambu
• Ubukhali obubukwayo

Olunye uvivinyo lungenziwa:

• I-Electroretinogram (ERG)
• Inkambu ebonakalayo

INyctanopia; INyctalopia; Ubumpumputhe basebusuku

• Ukwakheka kwamehlo kwangaphandle nangaphakathi
