Inkambu ebonakalayo

Inkambu ebonakalayo ibhekisa endaweni ephelele lapho izinto zingabonakala khona embonweni ohlangothini (wokuzungeza) njengoba ugxilisa amehlo akho ephuzwini eliphakathi.

Lo mbhalo uchaza isivivinyo esikala inkambu yakho ebonakalayo.

Ukuhlolwa kwensimu yokubukwa kokubhekana. Lesi isheke esheshayo nesisekelo senkambu ebonakalayo. Umhlinzeki wezempilo uhlala ngqo phambi kwakho. Uzomboza iso elilodwa, bese ubheka phambili ngqo kwelinye. Uzocelwa ukuthi utshele ukuthi ungasibona nini isandla somhloli.

Isikrini seTangent noma ukuhlolwa kwenkambu yeGoldmann. Uzohlala cishe ngamamitha amathathu (amasentimitha angama-90) kude nescreen sendwangu eyisicaba, emnyama enenhloso phakathi nendawo. Uzocelwa ukuthi ubheke kulokho okubhekiswe kukho futhi wazise umhloli ukuthi ungabona nini into ehamba ngombono wakho oseceleni. Into leyo ivamise ukuba yiphini noma ubuhlalu ekugcineni kwenduku emnyama enyakaziswa ngumhloli. Lokhu kuhlolwa kudala ibalazwe lamadigri wombono wakho ophakathi angama-30. Lokhu kuhlolwa kuvame ukusetshenziselwa ukuthola izinkinga zobuchopho noma zemizwa (neurologic).

I-perimetry yeGoldmann kanye ne-Automated perimetry. Kokukodwa kokuhlolwa, uhlala phambi kwedome ebunjiwe bese ubuka ilitshe phakathi. Ucindezela inkinobho lapho ubona ukukhanya okuncane embonweni wakho wangaphandle. Ngokuhlolwa kweGoldman, ukukhanya kuyalawulwa futhi kwenziwe imephu ngumhloli. Ngokuhlolwa okuzenzakalelayo, ikhompyutha ilawula ukukhanya nokuhlelwa kwemephu. Izimpendulo zakho zisiza ekutholeni ukuthi ngabe unenkinga ethile emkhakheni wakho wokubuka. Kokubili ukuhlolwa kuvame ukusetshenziselwa ukulandelela izimo ezingase zibe zimbi ngokuhamba kwesikhathi.

Umhlinzeki wakho uzoxoxa nawe ngohlobo lokuhlolwa kwenkambu yokubuka okufanele kwenziwe.

Akukho ukulungiselela okukhethekile okudingekayo.

Akukho ukungaphatheki kahle ngokuhlolwa kwenkambu ebonakalayo.

Lokhu kuhlolwa kwamehlo kuzokhombisa ukuthi ngabe ulahlekelwe yini ukubona noma yikuphi emkhakheni wakho wokubuka. Iphethini lokulahleka kombono lizosiza umhlinzeki wakho ukuthola imbangela.

Umbono womngcele ujwayelekile.

Imiphumela engajwayelekile ingahle ibangelwe yizifo noma ukuphazamiseka kohlelo oluphakathi lwezinzwa (CNS), njengezicubu ezilimaza noma ezicindezela (ukucindezela) izingxenye zobuchopho eziphathelene nombono.

Ezinye izifo ezingathinta inkambu yokubuka kweso zihlanganisa:

• Isifo sikashukela
• I-Glaucoma (ingcindezi yamehlo eyandisiwe)
• Umfutho wegazi ophezulu
• Ukwehla kwe-macular okuhlobene nobudala (ukuphazamiseka kwamehlo okubulala kancane umbono obukhali, ophakathi)
• I-Multiple sclerosis (ukuphazamiseka okuthinta i-CNS)
• I-optic glioma (isimila semizwa ye-optic)
• Indlala yegilo eyeqile (hyperthyroidism)
• Izinkinga ze-pituitary gland
• Ukuhlukaniswa kwe-retinal (ukuhlukaniswa kwe-retina ngemuva kweso kusuka ezingxenyeni zayo ezisekelayo)
• Unhlangothi
• I-arteritis yesikhashana (ukuvuvukala nokulimala kwemithambo ehambisa igazi ekhanda nakwezinye izingxenye zekhanda)

Ukuhlolwa akunazingozi.
