Pono - bofofu ba bosiu

Bofofu bosiu ha bo bone hantle bosiu kapa ha bo bobebe.

Bofofu ba bosiu bo ka baka mathata ka ho khanna bosiu. Batho ba nang le bofofu bosiu hangata ba na le bothata ba ho bona linaleli bosiung bo hlakileng kapa ba tsamaea ka phapusing e lefifi, joalo ka lebala la lifilimi.

Hangata mathata ana a ba mabe le kamora hore motho a be sebakeng se khanyang. Maemo a Milder a ka ba le nako e thata ea ho tloaela lefifi.

Lisosa tsa bofofu ba bosiu li oela likarolong tse peli: lia phekoleha ebile ha li phekolehe.

Lisosa tse ka phekolehang:

• Likotsi
• Ho se bone haufi
• Ts'ebeliso ea lithethefatsi tse itseng
• Ho haella ha vithamine A (ka seoelo)

Lisosa tse sa phekoleheng:

• Liphoso tsa tsoalo, haholoholo bofofu bosiu bo emeng bosiu
• Retinitis pigmentosa

Nka mehato ea polokeho ho thibela likotsi libakeng tsa khanya e tlase. Qoba ho khanna koloi bosiu, ntle le haeba u fumane tumello ho ngaka ea mahlo.

Lisebelisoa tsa vithamine A li ka thusa haeba u na le khaello ea vithamine A. Botsa mofani oa tlhokomelo ea bophelo hore na u lokela ho nka bokae, hobane ho a khonahala ho nka haholo.

Ho bohlokoa ho etsa tlhahlobo e felletseng ea mahlo ho fumana sesosa, se ka alafatsoang. Letsetsa ngaka ea mahlo haeba matšoao a bofofu bosiu a ntse a tsoela pele kapa a ama bophelo ba hau haholo.

Mofani oa hau o tla u hlahloba le mahlo a hau. Morero oa tlhahlobo ea bongaka ke ho bona hore na bothata bo ka lokisoa (mohlala, ka likhalase tse ncha kapa ho tlosoa ha lera la leihlo), kapa haeba bothata bo bakoa ke ho hong ho sa phekoleheng.

Mofani oa hau a ka u botsa lipotso, ho kenyelletsa:

• Bofofu ba bosiu bo matla hakae?
• Matšoao a hau a qalile neng?
• Na e etsahetse ka tšohanyetso kapa butle-butle?
• Na e etsahala ka linako tsohle?
• Na ho sebelisa lilense tsa tokiso ho ntlafatsa pono ea bosiu?
• Na u kile ua etsoa opereishene ea mahlo?
• U sebelisa meriana efe?
• Lijo tsa hau li joang?
• Na u sa tsoa lematsa mahlo kapa hlooho?
• O na le nalane ea lelapa ea lefu la tsoekere?
• O na le liphetoho tse ling tsa pono?
• U na le matšoao afe a mang?
• Na u na le khatello ea maikutlo e sa tloaelehang, ho tšoenyeha kapa ho tšaba lefifi?

Tlhahlobo ea mahlo e tla kenyelletsa:

• Ho lekoa ha pono ea mebala
• Seithuti se khanyang leseli
• Ho qhekella
• Tlhahlobo ea Retina
• Hlakola tlhahlobo ea lebone
• Matla a pono

Liteko tse ling li ka etsoa:

• Electroretinogram (ERG)
• Tšimo ea pono
