Ukubuka konke

IHemianopsia ukulahleka kombono engxenyeni yenkambu yakho yokubuka yeso elilodwa noma womabili amehlo. Izimbangela ezivamile yilezi:

• unhlangothi
• isimila sobuchopho
• ukuhlukumezeka ebuchosheni

Imvamisa, uhhafu wesobunxele wobuchopho bakho uthola imininingwane ebonakalayo ohlangothini lwesokunene lamehlo womabili, futhi ngokufanayo.

Olunye ulwazi oluvela emithanjeni yakho ye-optic luwela kolunye uhlangothi lobuchopho kusetshenziswa isakhiwo esimise okwe-X esibizwa nge-optic chiasm. Lapho noma iyiphi ingxenye yalesi simiso yonakele, umphumela ungaba ukulahleka kombono okuyingxenye noma okuphelele emkhakheni wokubuka.

Yini ebangela i-hemianopsia?

IHemianopsia ingenzeka uma kukhona ukulimala ku:

• Izinzwa ze-optic
• i-optic chiasm
• izikhungo zokucubungula ezibukwayo zobuchopho

Izimbangela ezivame kakhulu zokulimala kobuchopho okungaholela ku-hemianopsia yilezi:

• unhlangothi
• izimila
• ukulimala ekhanda okubuhlungu

Ngokuvamile, ukulimala kobuchopho nakho kungabangelwa:

• i-aneurysm
• ukutheleleka
• ukuvezwa ubuthi
• ukuphazamiseka kwe-neurodegenerative
• izehlakalo zesikhashana, njengokuquleka noma i-migraines

Izinhlobo ze-hemianopsia

Nge-hemianopsia, ungabona kuphela ingxenye yenkambu ebonakalayo kweso ngalinye. I-Hemianopsia ihlukaniswa yingxenye yenkambu yakho ebonakalayo engekho:

• okuncane: ingxenye engaphandle yenkambu ngayinye ebonakalayo
• homonymous: isigamu esifanayo senkambu ngayinye ebonakalayo
• kwesobunxele: uhhafu ongakwesokudla wenkambu ngayinye ebonakalayo
• kwesobunxele: kwesokunxele kwesigamu senkundla ngayinye yokubukwayo
• okuphezulu: uhhafu ophezulu wenkundla ngayinye yokubukwayo
• -phansi: uhhafu ophansi wenkambu ngayinye ebonakalayo

Ngifunani ku-hemianopsia?

Izimpawu zingadideka kalula nalezo ezinye izifo, ikakhulukazi ezimweni ze-hemianopsia engaphelele. Uma usola ukuthi ungaba ne-hemianopsia, bheka umhlinzeki wakho wezokunakekelwa kwempilo. Uma i-hemianopsia ivela ngokushesha noma ngokuzumayo, funa usizo lwezokwelapha ngokushesha.

Izimpawu zingafaka:

• ukuzwa ukuthi kukhona okungahambi kahle ngombono wakho
• ukushayisa izinto ngenkathi uhamba, ikakhulukazi ozimele bezicabha nabantu
• ukushayela kanzima, ikakhulukazi uma ushintsha imizila noma uvikela izinto eceleni komgwaqo
• ukulahlekelwa njalo indawo yakho ngenkathi ufunda noma unenkinga yokuthola ukuqala noma ukuphela komugqa wombhalo
• ubunzima bokuthola noma ukufinyelela ezintweni emadeskini noma kuzitafula noma kumakhabethe nasemakhabetheni

Ihlonza kanjani i-hemianopsia?

I-Hemianopsia ingatholakala ngokuhlolwa kwenkambu ebonakalayo. Ugxila ephuzwini elilodwa esikrinini ngenkathi amalambu akhonjiswa ngenhla, ngezansi, kwesobunxele, nangakwesokudla sendawo yaleyo ndawo yokugxila.

Ngokunquma ukuthi iziphi izibani ozibonayo, ukuhlolwa kuhlola ingxenye ethile yensimu yakho ebonakalayo eye yonakaliswa.

Uma ingxenye yensimu yakho yokubuka ingasebenzi kahle, kuvame ukuphakanyiswa ukuskena kwe-MRI. Iskena singabonisa ukuthi kukhona yini ukulimala kobuchopho ezindaweni zobuchopho obhekele ukubona.

Yelashwa kanjani i-hemianopsia?

Udokotela wakho uzokunikeza ukwelashwa okukhuluma ngesimo esibangela i-hemianopsia yakho. Kwezinye izimo, i-hemianopsia ingathuthuka ngokuhamba kwesikhathi. Lapho kwenzeka khona ukulimala kobuchopho, i-hemianopsia ivame ukuhlala unomphela, kepha ingasiza ngezindlela zokwelapha ezimbalwa.

Izinga lomsebenzi ongabuyiselwa lincike embangela nobukhulu bomonakalo.

Ukwelashwa kokubuyiselwa kombono (i-VRT)

I-VRT isebenza ngokuvuselela kaninginingi imiphetho yenkambu yombono engekho. Ingqondo yabantu abadala inekhono elithile lokuzifaka kabusha. I-VRT ibangela ubuchopho bakho ukuthi bukhulise ukuxhumana okusha ezindaweni ezonakele ukubuyisa imisebenzi elahlekile.

Kutholakale ukubuyisa okungaba ngamadigri ama-5 enkambu yokubuka elahlekile kwabanye abantu.

Usizo lwe-visual field expander

Izibuko ezikhethekile zingakufakela i-prism kulensi ngayinye. Lawa ma-prism agobisa ukukhanya okungenayo ukuze kufinyelele engxenyeni engonakalanga yenkambu yakho ebonakalayo.

Ukuskena ukwelashwa (ukuqeqeshwa kokunyakaza kwamehlo kwe-saccadic)

Ukuskena ukwelashwa kukufundisa ukuthuthukisa umkhuba wokuhambisa amehlo akho ukuze ubheke engxenyeni yenkambu ebonakalayo ongakwazi ukuyibona. Ukuguqula ikhanda lakho futhi kunweba insimu yakho yombono etholakalayo.

Ngokwakha lo mkhuba, ekugcineni uzofunda ukubheka njalo nenkambu yokubuka esasebenza kahle.

Amasu wokufunda

Amasu amaningi angenza ukufunda kungabi yinselele kangako. Ungabheka amagama amade ongawasebenzisa njengezindawo zokukhomba. Irula noma inothi elinamathelayo lingamaka ukuqala noma ukuphela kombhalo. Abanye abantu baphinde bazuze ngokuguqula umbhalo wabo ubheke eceleni.

Izinguquko zendlela yokuphila

Uma une-hemianopsia, ukwenza izinguquko ezimbalwa zendlela yokuphila kungasiza:

• Lapho uhamba nomunye umuntu, beka lowo muntu ohlangothini oluthintekile. Ukuba nomuntu lapho kuzokuvimbela ungqubuzana nezinto ezingaphandle kwensimu yakho yombono.
• Esikhathini semidlalo yaseshashalazini, hlala ubheke ohlangothini oluthintekile, ukuze isikrini sibe kakhulu ngasohlangothini lwakho olungathintekile. Lokhu kuzokhulisa inani lesikrini osibonayo.
• Ikhono lokushayela lizohluka kuye ngomuntu nomuntu. I-simulator yokushayela noma ukubonisana nomhlinzeki wezokunakekelwa kwempilo kungakusiza ukunquma ukuphepha.
