Abanye abantu bacinga ukuba bajonga ukuba amehlo akho ayabona na. Kodwa eneneni luvavanyo olunzulu nolubaluleke ngakumbi. Olu vavanyo alunakujonga nje kuphela impilo yamehlo akho, kodwa lukwafumana neempawu malunga nezinye izifo emzimbeni wakho wonke. Namhlanje sithetha ngolu vavanyo lubizwa ngokuba yiFundoscopy.
Yintoni kanye kanye i-fundoscopy?
Ngamafutshane, i-Fundoscopy kuxa ugqirha wakho ehlola udonga olungasemva lweliso lakho. Eli candelo leliso libizwa ngokuba yi-'fundus' ngokwezonyango. Yiyo loo nto olu vavanyo lubizwa ngokuba yi-Fundoscopy.
Isixhobo esisetyenziselwa oku sibizwa ngokuba yi-ophthalmoscope . Yiyo loo nto olu vavanyo lubizwa ngokuba yi-ophthalmoscopy . Esi sisixhobo esincinci esineelensi zokukhulisa kunye nokukhanya okuncinci. Sinokukhanyisa iliso lakho size sibone iindawo ezibalulekileyo ngaphakathi kweliso lakho ngokucacileyo size sikhulise.
Amehlo afana nefestile kungekuphela nje emphefumlweni wethu, kodwa nakwimpilo yethu yomzimba. Uvavanyo lwe-fundoscopy lunokubonisa okuninzi ngokujonga ngaphakathi ngaloo festile.
Kukho iindlela ezimbini eziphambili zokwenza olu vavanyo.
Zimbini iindlela eziphambili ugqirha angenza ngazo olu vavanyo. Izixhobo ezisetyenziswayo zahlukile kancinci.
| Indlela yovavanyo | Inkcazo |
|---|---|
| I-Ophthalmoscopy ethe ngqo | Oku kusebenzisa isixhobo esincinci esiphathwa ngesandla. Ugqirha uhlala phambi kwakho, abeke isixhobo kufutshane neliso lakho, aze ajonge ngaphakathi. Le yindlela oogqirha abadla ngokuyisebenzisa uninzi lwexesha. |
| I-Ophthalmoscopy engathanga ngqo | Kule meko, ugqirha usebenzisa isixhobo esinxitywa entloko (esifana nesibane sentloko). Ukongeza, ubamba enye ilensi phambi kweliso lakho. Le ndlela ikuvumela ukuba ubone indawo ebanzi ngaphakathi kweliso, ekhuliswe kakhulu, kwaye ibe nobukhulu obuthathu (3D). Iingcali zamehlo zisebenzisa le ndlela rhoqo. |
I-fundoscopy yenziwa nini?
Olu luvavanyo oluqhelekileyo kakhulu. Nazi ezinye iimeko apho unokufuneka wenze oku:
- Ngexesha lovavanyo lwezonyango ngokubanzi (uvavanyo lomzimba): Xa usiya kuvavanyo oluqhelekileyo, ugqirha angenza oku.
- Ixesha lokubonana nogqirha wabantwana: Oku kufuneka kwenziwe xa kufikwa kuvavanyo lwempilo yabantwana abancinci.
- Uvavanyo lwamehlo: Oku kuyimfuneko xa ubona ugqirha wamehlo xa uneengxaki zamehlo okanye iiglasi zamehlo.
- Uvavanyo lwe-neurological: Olu vavanyo lubaluleke kakhulu kwiimeko zengqondo kunye neemeko ezinxulumene nemithambo-luvo.
- Kubantu abanezifo ezifana nesifo seswekile kunye noxinzelelo lwegazi oluphezulu: Yiyo loo nto oogqirha becebisa ukuba abantu abanezi zifo bahlolwe amehlo abo rhoqo.
Kwenzeka ntoni ngaphambi nangexesha lovavanyo?
Akukho nto yokoyika ngolu vavanyo. Lulula kakhulu kwaye alunabuhlungu.
Ngaphambi kovavanyo
Ixesha elininzi, akuyi kufuneka wenze naluphi na ulungiselelo olukhethekileyo. Nangona kunjalo, ngamanye amaxesha, ingakumbi kwikliniki yamehlo, ukuba ugqirha ufuna ukubona kakuhle ngaphakathi kweliso lakho, banokufaka amaconsi athile emehlweni akho ukuze bavule iliso lakho.
Emva kokusebenzisa la mathontsi, amehlo akho aya kuba makhulu, ngoko ke usenokuba novelwano kancinci ekukhanyeni. Umbono wakho usenokuba lufifi kancinci. Oku kungathatha iiyure ezimbalwa.
Kubalulekile: Ukuba unezithontsi zamehlo ezenza amehlo akho abe makhulu, kuphephe ukuqhuba ngaloo mini. Ukuba kunokwenzeka, yiba nomnye umntu. Ukunxiba iiglasi zelanga kuya kunceda namehlo akho.
Ngexesha lovavanyo
Ugqirha uza kukucela ukuba uhlale esitulweni okanye ulale ebhedini. Olu vavanyo ludla ngokwenziwa ngezibane ezisegumbini ezifiphalisiweyo ukuze ukwazi ukubona kakuhle ingaphakathi leliso lakho.
Uza kucelwa ukuba ujonge phambili, kwaye ngamanye amaxesha uza kucelwa ukuba ujonge kwicala elahlukileyo. Ugqirha uza kuthatha i-ophthalmoscope yakhe aze ajonge elisweni lakho. Oku kuza kuthatha imizuzu embalwa. Awuyi kuva ntlungu ngeli xesha.
Olu vavanyo lujonga ntoni ngaphakathi kweliso?
Ugqirha akajongi nje ngaphakathi kweliso lakho. Kukho izinto ezimbalwa aza kuziqwalasela ngokukodwa:
- I-Retina: Le yinwebu ebonakala ekukhanyeni ngaphakathi kweliso. Ifana nefilimu ekwikhamera. Ijongwa ukuba ayinamonakalo na, ikhupha igazi, okanye ezinye iinguqu.
- I-Optic Nerve: Le 'yintambo' ethwala imiyalezo esuka elisweni ukuya engqondweni. Isiseko sale nerve (i-optic disc) sijongwa ukuba asidumbanga okanye asitshintshi umbala.
- Imithambo yegazi engaphakathi kweliso: Ngokujonga imithambo yegazi emincinci engaphakathi kweliso, ungafumana umbono wemeko yemithambo yegazi emzimbeni wonke.
- Impendulo yomfundi: Sikwaqwalasela nendlela amehlo akho asabela ngayo ekukhanyeni.
Zithini iziphumo zovavanyo?
Le yeyona nxalenye ibalulekileyo. I-Fundoscopy ingatyhila ulwazi oluninzi kungekuphela nje ngezifo zamehlo, kodwa nangezinye izifo emzimbeni.
Khawucinge nje, ugqirha wakho usenokufumanisa izinto ezinje ngolu vavanyo:
- Isifo seswekile: Isifo seswekile singonakalisa imithambo yegazi emincinci esweni. Oku kunokubangela ukopha okuncinci okanye ukuqokelelana kolwelo (ii-exudates) esweni . Le meko ibizwa ngokuba yiDiabetic Retinopathy .
- Uxinzelelo Lwegazi Oluphezulu: Uxinzelelo lwegazi oluphezulu lunokubangela ukuba imithambo yegazi engaphakathi kweliso ibe bhityile, ijijeke, kwaye iqine. Ngamanye amaxesha, oku kunokubangela ukopha.
- Uxinzelelo Oluphezulu Lwengqondo: Xa uxinzelelo ngaphakathi kwengqondo lusanda ngenxa yethumba lobuchopho, ukopha kwegazi, okanye esinye isizathu, ingcambu yemithambo-luvo ye-optic iyadumba. Le meko ibizwa ngokuba yi-papilloedema . Oku kunokubonwa lula nge-fundoscopy.
- IiCataracts: Olu vavanyo lunokubona ukufiphala kwelensi yeliso ukuya kuthi ga kwinqanaba elithile.
- I-Glaucoma: Olu vavanyo lunokufumanisa umonakalo kwi-optic nerve obangelwa kukunyuka koxinzelelo lwamehlo.
Emva kovavanyo, ugqirha uza kukuchazela oko akubonileyo. Ukuba kukho naziphi na iingxaki, banokucebisa ukuba kwenziwe olunye uvavanyo, olufana nokufota i-fundus (ukuthatha umfanekiso wangaphakathi kweliso) okanye uvavanyo lwesibane esiqhekekileyo , ukuze kufunyanwe unobangela.
