Ngaba wakha wazibona izibane ezinemibala, amachaphaza akhanyayo, okanye iinkwenkwezi xa uvala amehlo akho okanye ukwigumbi elimnyama kakhulu? Kwizonyango, ezi zinto sizibiza ngokuba yiPhosphenes kuba sizibona ngaphakathi kwamehlo ethu, nokuba akukho kukhanya. Ngamanye amaxesha oku kunokuba yinto eqhelekileyo, engenabungozi. Nangona kunjalo, ngamanye amaxesha kunokuba luphawu lokuqala lwengxaki ngaphakathi kweliso okanye engqondweni. Ke namhlanje, masithethe ngezi Phosphenes ngendlela elula.
Zinjani ezi phosphenes zibonakalayo?
Abantu abaye bakubona oku bakuchaza ngeendlela ezahlukeneyo. Abanye bathi kubonakala ngathi yimpuphu ekhazimlayo edada phambi kwamehlo abo. Abanye bathi kubonakala ngathi ziinkwenkwezi ziyabhabha. Ngamanye amaxesha, ungabona neemilo ezahlukeneyo zejometri. Into ebalulekileyo kukuba akukho kukhanya kwangaphandle kufuneka kungene emehlweni ukuze ubone ezi zinto.
Kutheni sibona ii-phosphenes ngolu hlobo? Zithini izizathu eziphambili?
Zininzi izizathu ze-phosphenes. Ngamanye amaxesha zinokwenzeka ngaphandle kwesizathu esicacileyo. Makhe sijonge ezona zizathu ziphambili.
Izizathu ezilula neziqhelekileyo
Khawucinge nje ukuba uvala amehlo akho uze uwacinezele kancinci ngesandla sakho, okanye ukuba uvula amehlo akho, xa uwavula, ngequbuliso ubona ukukhanya, akunjalo? Lo ngumzekelo olula wePhosphenes. Kwakhona,
- Xa intloko ibetha into ethile: Sikwathi "Ndibone iinkwenkwezi." Xa intloko ibetha into ethile ngamandla, uxinzelelo olusesweni lunokuvuselela iiseli ze-photoreceptor ngaphakathi kweliso, nto leyo ebangela ukuba ukukhanya kukhanye.
- Xa ukhohlela okanye uthimla kakhulu: Ii-Phosphenes nazo zinokwenzeka ngeli xesha ngenxa yoxinzelelo entlokweni namehlo.
- Xa usukuma ngokukhawuleza: Abanye abantu, ingakumbi abo banegazi eliphantsi, banokubona iinkwenkwezi zibhabha phambi kwamehlo abo xa bema ngequbuliso behleli. Oku kungenxa yokuba ukuhamba kwegazi ukuya ebuchotsheni kuyehla ngequbuliso.
Ii-phosphenes ezibangelwa zizinto ezilula ezifana nezi azisoloko zixhalabisa. Zivela apha naphaya zize zinyamalale.
Izizathu zonyango ekufuneka ziqwalaselwe
Ii-phosphenes zinokwenzeka ngezizathu ezilula, kunye nophawu lwezinye izifo ezinzulu. Masizihlukanise zibe ziindidi ezimbini: iingxaki zamehlo kunye neengxaki zenkqubo yemithambo-luvo.
1. Iingxaki zeRetina
I-retina yi-membrane ebonakala ekukhanyeni ngaphakathi kwamehlo ethu ebamba ukukhanya. Ifana nefilimu ekwikhamera. Iingxaki ngale nto zinokubangela ii-phosphenes.
| Imeko yezonyango | Ingcaciso elula |
|---|---|
| Ukuhlukaniswa kweRetinal | Le yingxamiseko yezonyango. I-retina iyahlukana nezicubu ezixhasayo. Ukuba ayinyangwa ngokukhawuleza, inokubangela ubumfama. Ukuba ubona ii-floaters phambi kwamehlo akho kunye ne-phosphenes, bona ugqirha ngokukhawuleza. |
| Ukususwa kweVitreous yangasemva | Ijeli ye-vitreous engaphakathi kweliso iyasuka kwi-retina. Le yimeko eqhelekileyo eyenzekayo njengoko sikhula. |
| Ukonakala kwamehlo ngenxa yesifo seswekile (i-Diabetic Retinopathy) | Ukuba isifo seswekile asilawulwa, le meko inokubangelwa kukonakala kwemithambo yegazi esweni. |
| Ukonakala kweMacular okunxulumene nobudala | Oku kuchaphazela kakhulu umbono ophakathi kwaye kubangelwa kukonakala kwe-macula, inxalenye ye-retina. |
2. Iingxaki ze-neurological
Ii-phosphenes zinokuba luphawu lweengxaki zengqondo kunye nemithambo-luvo.
| Imeko yezonyango | Ingcaciso elula |
|---|---|
| I-Optic Neuritis | Ukudumba okanye usulelo lwe-optic nerve, edibanisa iliso nengqondo. Le meko ngamanye amaxesha inokuba luphawu lokuqala lwesifo esibizwa ngokuba yiMultiple Sclerosis (MS). |
| Intloko ebuhlungu | Abanye abantu bafumana ukuphazamiseka kokubona (visual auras) ngaphambi kokuba bahlaselwe yi-migraine. Ngeli xesha, banokubona ii-phosphenes, ezizizibane okanye iimilo ezahlukeneyo. |
| Ukuxhuzula | I-Mesmerism ibangelwa ngumsebenzi wombane ongalawulekiyo engqondweni. Olu vuselelo lombane lunokubangela ii-phosphenes. |
| Ezinye izifo ze-neurological | Oku kunokubonwa nakwiimeko ezifana ne-dementia, isifo sikaParkinson, kunye nokungasebenzi kakuhle kwemisipha. |
| Ukulimala Kwengqondo Okubuhlungu | Ii-phosphenes zinokubakho njengophawu lomonakalo wengqondo obangelwa kukwenzakala entloko. |
Ezinye izizathu
Ukongeza kwezi zizathu zingasentla,
- Unyango lwemitha lomhlaza, ingakumbi entloko, entanyeni, okanye emehlweni.
- Unyango lweTranscranial Magnetic Stimulation (TMS) lweengxaki zemithambo-luvo ezifana nokudakumba.
- Ukusetyenziswa kwamayeza athile, iziyobisi, okanye utywala.
- Njengeempawu zokurhoxa xa uyeka utywala okanye amayeza athile.
Sifanele siye kugqirha nini ngale nto?
Le yeyona nxalenye ibalulekileyo. Nangona kuqhelekile ukuzibona ezi zinto xa ufinya amehlo, ukuba unezinye zeempawu ezilandelayo, ngokuqinisekileyo kuya kufuneka ubone ugqirha, ingakumbi ugqirha wamehlo.
- Ukuba ubona rhoqo ii-phosphenes: Ukuba uhlala ubona izibane phambi kwamehlo akho ngaphandle kwesizathu.
- Ukuba ubona izinto ezidadayo: Ukuba ubona izinto ezifana ne-spider webs okanye amachaphaza amnyama edada phambi kwamehlo akho xa ujonge ukukhanya, oku kungaba luphawu lokuqhekeka kwe-retina.
- Ukuba umbono wakho uba luzizi (umbono ofipheleyo) okanye ubona izinto njengezimbini (iDiplopia).
- Ukuba unesifo seswekile: Ukuba umntu onesifo seswekile ufumana ezi mpawu, isenokuba luphawu lokuba kukho umonakalo emehlweni.
- Ukuba inxalenye yombono wakho ivakala imnyama.
Ii-Phosphenes azisoloko ziyingozi. Nangona kunjalo, ngamanye amaxesha zinokuba luphawu lokuqala lwesifo esinzima. Ngoko ke ukuba unamathandabuzo, okanye ukuba unempawu entsha, kungcono ukuthetha nogqirha wakho uze uyilungise ngaphandle kokuyityeshela.
Ii-phosphenes ziphathwa njani?
Ngamafutshane, akukho nyango lukhethekileyo lweempawu ze-phosphenes. Oogqirha bazama ukufumana unobangela oyintloko baze banyange loo nobangela.
Umzekelo, ukuba unobangela sisifo seswekile, isifo seswekile kufuneka silawulwe kakuhle. Ukuba unobangela kukwahlukana kwe-retina, kufuneka sinyangwe ngoko nangoko. Ukuba yi-migraine, kufuneka kuthathwe amayeza afanelekileyo. Ngoko ke, ukufumana unobangela linyathelo lokuqala nelibalulekileyo kunyango.
Umyalezo Wokuya Ekhaya
- Iiphosphenes zizinto ezibonakalayo apho iliso libona khona izibane, iinkwenkwezi, okanye iimilo ezahlukeneyo ngaphandle kokukhanya kokwenyani.
- Ii-phosphenes ezibangelwa zizinto ezilula ezifana nokukhuhla amehlo, ukukhohlela, okanye ukubetha intloko azisoloko zixhalabisa.
- Nangona kunjalo, zinokubakho njengophawu lwezifo ezinzulu ezifana neengxaki ze-retina, iimeko zemithambo-luvo, kunye nesifo seswekile.
- Ukuba ufumana ii-phosphenes rhoqo, ezihamba nezinye iimpawu ezifana nokungaboni kakuhle okanye ukubona izinto ezidadayo, funa ingcebiso kagqirha ngokukhawuleza, ingakumbi kwingcali yamehlo.
- Unyango alukho kwi-phosphenes ngokwazo, kodwa lulolwemeko yempilo ebangela ezo ngxaki. Ukuba unenkxalabo malunga nokubona kwakho, ungaze uyityeshele loo nto.
