Xa wakha waya kuhlolwa amehlo, ngaba ugqirha wafaka into efana nolwelo olumthubi esweni lakho ngephepha elincinci? Okanye wafaka amathontsi atyheli kulo? Ngaba iinyembezi zakho zajika zaba mthubi emva kokuba efake? Abantu abaninzi bayoyika kancinci xa bebona oku. Kodwa eneneni akukho nto yokoyika. Le yidayi ekhethekileyo ebizwa ngokuba yiFluorescein, ebaluleke kakhulu kwiimvavanyo zamehlo. Ngoko ke masithethe ngayo yonke into ngokulula namhlanje.
Yintoni iFluorescein?
Ngamafutshane, iFluorescein yidayi etyheli-luhlaza okotshani, okanye i-pigment . Yinto engenabungozi engenabungozi emehlweni. Isebenza njengokudaya ilaphu, yenza izinto ezithile ngaphakathi kweliso zibonakale kuthi.
Oku kudla ngokuza ngeendlela ezimbini:
- Imicu: Le dayi isetyenziswa kwincam yomcu obhityileyo wephepha. Ugqirha uza kumanzisa incam yomcu ngesisombululo setyuwa encinci aze ayibeke ngobunono phantsi kwejwabu leso lakho.
- Amaconsi amehlo: Ngamanye amaxesha oku kuza ngendlela yamaconsi.
Kungakhathaliseki ukuba uyisebenzisa ngayiphi na indlela, xa uvala amehlo akho, le dayi ixubana neenyembezi zakho kwaye isasazeke emehlweni akho.
Kutheni oogqirha besebenzisa oku?
I-Fluorescein ifana nesixhobo somcuphi kugqirha wamehlo. Ingatyhila izinto ezininzi ezingenakubonwa ngamehlo enyama. Makhe sijonge izizathu eziphambili.
| Imeko yokusetyenziswa | Kwenzekani? |
|---|---|
| Chonga ii-Corneal Abrasions | Isuntswana lothuli, isinambuzane esincinci, okanye uzipho lunokubangela umkrwelo. Le mikrwelo ayisoloko ibonwa. Xa kusetyenziswa i-fluorescein, idayi iyahlanjwa kwiindawo eziphilileyo zeliso, kodwa umbala otyheli uhlala apho kukho umkrwelo okanye inxeba. Xa ugqirha ekhanyisa isibane esiluhlaza okwesibhakabhaka esikhethekileyo (isibane esiluhlaza okwesibhakabhaka se-cobalt), indawo apho ishiywe khona ikhanya ngombala oluhlaza okwesibhakabhaka. Oku kuvumela ugqirha ukuba abone ngqo apho inxeba likhona kwaye likhulu kangakanani. |
| Jonga ukuba iilensi zoqhagamshelwano zilingana kakuhle na. | Le dayi isetyenziselwa ukujonga, ingakumbi xa kufakwa iilensi zoqhagamshelwano eziqinileyo neziqinileyo ezingena kwigesi, ukuba zilingana kakuhle na iliso, nokuba ziqinile na naphi na, okanye ukuba ifilimu yokukrazula phakathi kweliso nelensi ayitshintshanga na. |
| Ukulinganisa uxinzelelo lwamehlo (iTonometry) | Le dayi isetyenziswa nezinye izixhobo ezilinganisa uxinzelelo lwamehlo (applanation tonometry) ukujonga izifo ezifana neglaucoma. Ifilimu yokukrazula eyenziwe yidayi inceda isixhobo ukuba silinganise uxinzelelo ngokuchanekileyo. |
| Jonga ukuba imibhobho yokukrazula ivaliwe na. | Iinyembezi zabanye abantu ziqokelelana emehlweni endaweni yokuba ziphume. Ukuze kubonwe ukuba imibhobho yeenyembezi (imibhobho yeenyembezi) ivaliwe na, kwenziwa uvavanyo lokujonga ukuba ihlala ixesha elingakanani esweni (ixesha lokuqhekeka kwenyembezi) ngokufaka iFluorescein esweni. |
Izinto ekufuneka uzixelele ugqirha wakho ngaphambi kokuba usebenzise le nto
Nangona i-fluorescein iyinto ekhuselekileyo kakhulu, njengakuvavanyo lwezonyango, kukho izinto ezimbalwa ekufuneka uzixelele ugqirha wakho.
- Ukuba unxiba iilensi ezithambileyo zokunxibelelana: Oku kubaluleke kakhulu. Le dayi inokungcolisa iilensi zakho ezithambileyo zokunxibelelana ngokusisigxina. Ngoko ke, kufuneka uzisuse iilensi zakho ngaphambi kovavanyo.
- Malunga ne-allergies zakho: Qiniseka ukuba uyakhankanya ukuba ukhe waba ne-allergy kwi-fluorescein, amanye amayeza, ukutya, ezinye iidayi, okanye izithinteli.
- Ukuba ukhulelwe okanye uzama ukukhulelwa: Nangona oku kudla ngokuthathwa njengokukhuselekileyo ngexesha lokukhulelwa, kubaluleke kakhulu ukwazisa ugqirha wakho ngemeko yakho.
- Ukuba ungumama oncancisayo: Thetha nogqirha wakho ngale nto.
Ngokuxelela ezi zinto kwangaphambili, ugqirha wakho unokugqiba ukuba yeyiphi eyona ilungileyo nekhuselekileyo kuwe.
Ngaba oku kungabangela iziphumo ebezingalindelekanga?
Iziphumo ezibi kakhulu nge-fluorescein azixhaphakanga, kodwa kulungile ukwazi ukuba yintoni enokwenzeka.
Khumbula, le yinto esetyenziswa ngugqirha okanye yingcali yezonyango eqeqeshiweyo kuphela ngexesha lovavanyo lwamehlo. Awuyi kuvunyelwa ukuyithatha uye nayo ekhaya. Ngoko ke akukho ngxaki yokungayisebenzisi idosi okanye ukuthatha kakhulu.
| Iziphumo ebezingalindelekanga ezinzulu ekufuneka zixelwe kugqirha wakho/kwi-ETU ngoko nangoko (azifane zenzeke) | |
|---|---|
| Iimpendulo Ezinzima Zokwaliwa Yi-Allergic | Yimeko engxamisekileyo ukuba ufumana iimpawu ezifana nokurhawuzelela eluswini, ukurhawuzelela, ukurhawuzelela okukhulu, ukudumba kobuso, imilebe okanye ulwimi, okanye ubunzima bokuphefumla. Nangona kunjalo, oku kunqabile kakhulu xa usebenzisa iFluorescein. |
| Akukho nto idla ngokuxhalabisa ngayo, kodwa ukuba iyaqhubeka, nazi izinto onokuzixelela ugqirha wakho: | |
| Iinyembezi zijika zibe tyheli | Kuqhelekile ukuba iinyembezi zakho zibe tyheli kangangemizuzu embalwa okanye iiyure emva kokufaka i-fluorescein. Oku kuya kuphela emva kwexesha elithile. Ukuba kukho nantoni na ephuma empumlweni yakho, inokuba tyheli. |
| Utshintsho lombala kwiilensi zoqhagamshelwano ezithambileyo | Njengoko benditshilo ngaphambili, ukuba unxiba iilensi ezithambileyo zokunxibelelana, oku kungazingcolisa ngonaphakade. Yiyo loo nto kufuneka uzisuse iilensi zakho ngaphambi kovavanyo. |
Izinto ekufuneka uzilumkele emva kokusebenzisa iFluorescein
Eyona nto ibalulekileyo kukuba ukuba unxiba iilensi ezithambileyo zokunxibelelana , ungaziphindi uzifake ubuncinane iyure emva kokusebenzisa iFluorescein. Ugqirha wakho angakuxelela ukuba ulinde ixesha elide, njengoko idayi eseleyo esweni lakho inokujika umbala weelensi zakho ngonaphakade. Landela imiyalelo kagqirha wakho ngokuchanekileyo.
Ekubeni iinyembezi zakho zimthubi, ukuba uzisula ngethishu, nazo ziya kuba mthubi. Yinto eqhelekileyo leyo, ungakhathazeki. Kwakhona, ungaziva urhawuzelelwa kancinci xa ufaka amaconsi eliso, kodwa oko kuya kuphela kwimizuzwana embalwa.
Umyalezo Wokuya Ekhaya
