Uke wakubona ukukhanya noma imicu yokukhanya ezingxenyeni zeso lakho futhi wazibuza ukuthi kwenzekani? Ukukhanya esweni lakho uhlobo lwe-photopsia, noma ukuphazamiseka kombono.

Ukukhanya kokukhanya kungenzeka emehlweni akho noma womabili futhi kunezimo ezihlukile, imibala, imvamisa nobude besikhathi. Kunezimbangela eziningi zalokhu.

Ake sihlolisise izimbangela zokukhanya okukhanyayo esweni lakho nokuthi yini ongayenza ngazo.

Ukwakheka kwamehlo nokukhanya

Ake sicabangele umsebenzi we-retina nama-vitreous humor ukuze sikuqonde kangcono lokhu kukhanya.

• I-retina iyisicubu esincanyana esinozwela olula ngemuva ngaphakathi kweso lakho. Idlulisela amasiginali kagesi ebuchosheni bakho nge-optic nerve. Umsebenzi we-retina ukucubungula ukukhanya okugxile okuza ngomfundi wakho nokuvumela ubuchopho bakho buguqule lolu lwazi lube isithombe.
• I-vitreous humor iwuketshezi olucacile olufana ne-jelly oluthatha ingxenye enkulu engemuva kweso lakho. Ivikela i-retina futhi isiza iso lakho ligcine isimo salo.

Ngenkathi kunezizathu eziningi ongabona ukukhanya kokukhanya esweni lakho, ingcindezi noma amandla ku-retina imvamisa kuyizimbangela. Lokhu kukhanya kokukhanya kwenzeka engxenyeni engemuva yeso lakho lapho kutholakala khona i-retina.

Imicu emincane intanta ku-vitreous fluid futhi inamathiselwe ku-retina. Lapho le micu idonswa noma ihlikihlwa, kungadala ukukhanya noma izinhlansi zokukhanya kusuka ekuxabaneni.

Ukukhanya kokukhanya esweni ngokuvamile akusona isimo sisodwa. Esikhundleni salokho, bavame ukuba uphawu lwesinye isimo.

Yiziphi izimbangela ezingaba khona?

Ngokwe-American Academy of Ophthalmology, ukubona ukukhanya kokukhanya ekhoneni leso lakho kungadalwa yizimo noma izimo ezahlukahlukene. Ezinye izimbangela zingahlobene nempilo yamehlo akho, kanti ezinye zingahle zihlobene nezinye izinhlobo zezimo zezempilo.

Izinkinga ezihlobene neso

Izinhlobo eziningi zezinkinga ezihlobene neso zingadala ukuthi ukukhanya kokukhanya kuvele ekhoneni leso lakho noma emkhakheni wokubona.

Izimbangela ezihlobene neso

• Ibutho le-poster vitreous. Lesi ngesinye sezimbangela ezivame kakhulu zokukhanya kokukhanya esweni lakho. Ngokuvamile kwenzeka njengoba ukhula. Ngokwehlukaniswa kwe-vitreous ngemuva, i-vitreous humor iyasuswa kwi-retina. Uma kwenzeka ngokushesha okukhulu, kungadala ukukhanya okuncane, imvamisa ekhoneni lombono wakho. Kungadala nokuntanta. Lesi simo asidingi ukwelashwa.
• I-optic neuritis. I-optic neuritis yenzeka lapho i-optic nerve ivutha. Lokhu kungabangelwa ukutheleleka noma ukuphazamiseka okuhlobene nemizwa okunjenge-multiple sclerosis. Ukukhanya kokukhanya kungaba uphawu lwalesi simo.
• Ukuhlukaniswa kwe-retinal. Ukuhlukaniswa kwe-retinal yisimo esibi esingadala ukulahleka okuncane noma okuphelele kombono. Lapho lokhu kwenzeka, i-retina iyanqamuka, ishintshe noma isuke odongeni lwangemuva lweso.
• Ukucindezela ku-retina. Uma uhlikihla amehlo akho, ukhwehlela kanzima, noma ushayeke ekhanda, ungahle ubone ukukhanya okukhanya ngenxa yengcindezi eyengeziwe ku-retina.

Ezinye izindaba zezempilo

Ukukhanya kokukhanya esweni lakho kungenzeka kungabangelwa inkinga ehlobene neso. Kungaba uphawu lwesimo sempilo esihlukile.

Ezinye izimbangela ezihlobene nempilo

• Isithuthwane emsebenzini. Lolu hlobo lokuthwebula olungavamile ku-lobe ye-occipital yobuchopho lungadala ukukhanya okubonakalayo esweni. Kungaba uphawu lomsebenzi wokubamba. Lokhu kwesinye isikhathi kutholakala ngephutha njenge-migraine aura. Ngokuvamile, noma kunjalo, isithuthwane se-occipital sifushane (imizuzu emibili) uma kuqhathaniswa ne-migraine aura (imizuzu engu-15 kuye kwengu-60).
• Migraine. Ukuphazamiseka okubonakalayo kuvamile nge-migraine aura. Ungabona ukukhanya, imigqa yama-zigzag, izinkanyezi, noma amachashazi wokukhanya emehlweni akho. Lezi zimpawu zivame ukuphela kungakapheli imizuzu engama-60.
• Ukuhlaselwa kweschemic kwesikhashana (TIAs). Ngokuvamile okubizwa ngokuthi ama-ministrokes, ama-TIA ayenzeka lapho ihlule legazi livimbela okwesikhashana ukugeleza kwegazi kuya ebuchosheni bakho. Ama-TIA angadala ukuphazamiseka okubukwayo, kufaka phakathi ukukhanya kokukhanya emehlweni akho.
• Isifo sikashukela. Ukukhanya kwamalambu okukhanya noma okuntanta kungaba uphawu lokuphindaphindwa kwesifo sikashukela.
• Izimila. Izimila ezindaweni ezihlukene zamehlo noma zobuchopho zingakhipha ukukhanya lapho uhambisa ikhanda noma intamo yakho.
• Ukulimala. Ukulimala ngqo esweni lakho kungadala ukuthi ubone ukukhanya noma "izinkanyezi" ngenxa yengcindezi kwi-retina.
• Imithi. Eminye imithi ingadala ukukhanya noma okuntantayo emehlweni akho. Lokhu kufaka:
  • i-bevacizumab (Avastin)
  • I-sildenafil (Viagra, Revatio)
  • clomiphene (Clomid)
  • i-digoxin (Lanoxin)
  • i-paclitaxel (Abraxane)
  • i-quetiapine (iSeroquel)
  • i-quinine
  • i-voriconazole (Vfend)

Ukubonana nodokotela nini

Ukuhlukaniswa kwe-retinal kuyisimo esiphuthumayo sezokwelapha futhi kudinga ukunakekelwa kwezokwelapha ngokushesha ukuvimbela ukulahleka kombono. Uma unezimpawu ezilandelayo, thola usizo lwezokwelapha ngokushesha:

• ukukhanya okungazelelwe kokukhanya, ikakhulukazi uma ubheka eceleni
• ukulahleka kombono okuyingxenye noma umbono omnyama
• ukungaboni kahle
• isiyezi
• ezinye izinkinga ezihlobene nombono ngokuzumayo

I-TIA kaningi ingaba uphawu oluyisixwayiso sohlangothi. Yingakho kubalulekile ukuthi ungazinaki izimpawu. Uma ubona noma yiziphi kulezi zimpawu ezilandelayo, thola usizo lwezokwelapha ngokushesha okukhulu:

• ubuthakathaka noma ukuba ndikindiki kolunye uhlangothi lomzimba wakho
• ukukhuluma okungaqondakali noma ubunzima bokukhuluma noma ukuqonda abanye
• ukuphazamiseka okubukwayo noma izinguquko ezibukwayo
• isiyezi
• ikhanda elibi kakhulu

Yenza i-aphoyintimenti yokubona udokotela wamehlo, udokotela wamehlo, noma udokotela wakho oyinhloko uma:

• ube nokwanda okungazelelwe kokukhanya kokukhanya esweni noma emehlweni akho
• qaphela ukwanda kosayizi nenani lamafulethi
• ube noshintsho olungazelelwe kumbono wakho
• ube nokwanda kwama-auras abukwayo ane-migraine

Udokotela wakho anganquma imbangela yokukhanya kokukhanya ngokuya ngohlobo, ubude besikhathi nendawo yalokhu kuphazamiseka okubukwayo.

Noma yikuphi ukulimala okungathi sína esweni lakho nakho kudinga usizo lwezokwelapha ngokushesha.

Kuphathwa kanjani ukukhanya kweso?

Ukukhanya kokukhanya esweni lakho ngokuvamile kuwuphawu lwenkinga ehlobene namehlo akho noma esinye isimo sempilo. Ukwelashwa kuzoya ngombangela oyimbangela.

Lapho ubona udokotela wakho, qiniseka ukuthi uphenya yonke imithi oyiphuzayo njengamanje. Eminye imithi ingadala imiphumela emibi ehlobene nombono.

Kwezinye izimo, njenge-optic neuritis, ukwelapha imbangela yokuvuvukala noma ukutheleleka kungamisa ukukhanya.

Izinyembezi ku-retina noma ebuthweni le-retinal zingadinga ukuhlinzwa.

Akukho ukwelashwa kokuncipha kwe-vitreous okujwayele ukwenzeka ngokukhula.

Okubalulekile

Ukukhanya kokukhanya kungadalwa yizinkinga ezahlukahlukene. Ezinye kungenzeka zihlobene neso lakho kanti ezinye zingaba uphawu lolunye uhlobo lwesimo, njenge-migraine, isithuthwane, isifo sikashukela, noma ama-TIA.

Ukuhlala ngaphezulu kwempilo yeso lakho, qiniseka ukubona udokotela wamehlo wakho ukuze ahlolwe okungenani kanye ngonyaka. Ukuhlolwa kwamehlo njalo kungasiza udokotela wakho ukuthi anqume ukuthi ngabe kube khona ushintsho kumbono wakho noma impilo yamehlo akho.
