"Uvavanyo lwe-puff air" lusetyenziso lwexesha le-tonometry (non-contact) ye-tonometry (NCT), uvavanyo olwenziwe ngexesha lokuhlolwa kwamehlo ukulinganisa uxinzelelo ngaphakathi kweso lakho. Uvavanyo lwe-puff air lunikeza ugqirha weziliso ukuba ufunde ukunyanzeliswa kwamehlo, eyaziwa ngokuba nguxinzelelo lwe-intraocular (IOP), enceda ukufumana i- glaucoma .
"I-tonic tonometry" kukuvavanya ukuvavanya kwezilwanyana zamehlo kodwa ngezinye izihlandlo.
Olu vavanyo alunakulungile njengoko i-tonometry yendabuko kodwa lubuhlungu kakhulu ekufumaneni iingxaki zengcinezelo. Abantu abaninzi banqwenela ukuvavanya ukukhwabanisa ngomoya kungabikho nxu lumnxeba olwenziwe ngeso. Ukuqhayisa umoya oya kuziva ukuba akubuhlungu.
Ukunyaniseka kwamehlo
I-tonometry ngqo ebusweni bamehlo isilinganisi esicacile ngakumbi seengcinezelo zeso. Nangona kunjalo, olu hlobo lovavanyo lufuna isicwecwe sekhono ukwenza ngokuchanekileyo. Ngaphambi kokuba uvavanyo luqhutywe, i-technician iya kuphazamisa iliso nge-anesthetic. Ngexesha loviwo, i-sensor ifakwe ngenyameko ebusweni belihlo, ukunika ukufunda ngokuchanekileyo kwe-IOP. Ngenxa yokuba i-tonometer yendabuko kufuneka idibanise nelihlo ukuze ifumane umlinganiselo wokunyanzeliswa, abaninzi abantu bacela ukuhlolwa kwe-puff air. Uvavanyo lwe-puff air lukhupha umoya omnene kwi-iso, ngoko ulinganisa ixesha elithathayo ukuba umoya udibanise indawo encinane ye-cornea kwaye ubuyele kwisixhobo.
Ukunyamezela kwamehlo okuphakanyisiweyo
Kuthekani kuthi ukuba uvavanyo lwe-puff air luphumela ekufundeni okuphezulu? I-IOP ephakamileyo ngamanye amaxesha ibizwa ngokuba yi-ocular blood pressure. Uxinzelelo lwemehlo oluphakamileyo alubonakalisi ngokuzenzekelayo i-glaucoma, kodwa likubeka engozini yokuphuhlisa eso sifo. Ugqirha lakho kwamehlo liya kufuna ukujonga ingcinezelo yamehlo akho rhoqo xa uvakatye, ukuqinisekisa ukuba ezinye iimpawu ze-glaucoma azihlakuleli.
I-Glaucoma iyisifo esibalulekileyo seso esingabangela ukulahlekelwa kombono xa kungaphathwa unyango. Ngenxa yokuba loo mqathango ayivelisi iimpawu ezicacileyo, ukuvavanya komoya ngamanye amaxesha kuyindlela kuphela yokuba ugqirha ayibone. Nangona kunjalo, ukwanda ngokukhawuleza kwenycinezelo yamehlo, ngokukodwa kwimeko ye-glaucoma ye-angle-closure-closure, inokuvelisa ezinye iimpawu ezibandakanya umbono ophazamisayo, ii-halos ezijikelezileyo izibane, intlungu yesohlo kunye nentloko. I-glaucoma yokuvalwa kwe-Angle iyabunqabile kodwa inzima. Ngaphandle kokuba uphathwe ngokukhawuleza, loo mqathango inokubangela ukuba ungaboni. Ukuba ufumana iimpawu ezingentla, khangela unyango ngokukhawuleza ukuze uhlalutye.
Oko Okufanele Uyazi
Uvavanyo lwe-puff air luzuzisa kwi- tonometry yendabuko ekubeni lunokwenziwa ngekhono elingaphantsi kwaye lwenziwa ngutitshala. Kwakhona, ayithinti iso, ngoko akukho nto ixhalabisa ngayo. Ngaphezu koko, akukho manzi amaconsi ayadingeka phambi kovavanyo.
Abanye oogqirha banomuvo wokuvavanya ukuba uvavanyo lwe-puff air aluchanekanga njengetoniometer yendabuko echaphazela ngamehlo. Nangona kunjalo, oku kunokuxhomekeka ngakumbi kwi-brand yangempela ye-NCT kunye neepropati zesiguli seziliso.
Eyaziwa ngokuba njenge- Non-Contact Tonometry (NCT)
