Ngaba wakha wahlolwa amehlo ngugqirha waza wakuxelela ukuba ulinganise ubukhulu be-cornea yakho? Usenokuba uxelelwe ukuba wenze 'uVavanyo lwePachymetry'. Abantu abaninzi baziva bengaqhelekanga xa besiva eli gama, becinga ukuba luvavanyo olukhulu okanye luza kubuhlungu. Ngoko ke namhlanje, masithethe ngokuba luyintoni olu Vavanyo lwePachymetry, kutheni lwenziwa, kwaye nokuba ufanele uloyike na.
Ngamafutshane, yintoni le Pachymetry Test?
Ngamafutshane, uvavanyo lwePachymetry luvavanyo olulinganisa ubukhulu be-cornea yakho. Ngoku usenokuba uzibuza, "Yintoni le cornea?"
I-cornea yinwebu ebhityileyo, ebonakala ngokucacileyo, efana newotshi ngaphambili kweliso lethu. Inemisebenzi emibini ephambili:
1. Isinceda sibone ngokucacileyo ngokugxila ekukhanyeni okungena emehlweni.
2. Ukukhusela amehlo eluthulini nakwiintsholongwane.
Ngoko ke, olu vavanyo lwePachymetry lulinganisa ubukhulu be-cornea ngee-micrometer. Oku kunika ugqirha ulwazi olubaluleke kakhulu malunga nempilo yeliso. Ngamanye amaxesha olu vavanyo lwenziwa kunye novavanyo olubizwa ngokuba yi-'Corneal Topography', oludala imephu yomphezulu we-cornea.
Kweziphi iimeko olu vavanyo lwenziwa kuzo?
Ugqirha angayalela olu vavanyo ngezizathu ezahlukeneyo. Ezona zixhaphakileyo zezi:
- Ukuxilongwa kunye noNyango lweGlaucoma: I-Glaucoma sisifo apho uxinzelelo ngaphakathi kweliso (Uxinzelelo lwe-Intraocular - IOP) lunyuka kwaye lunokonakalisa umthambo we-optic. Oogqirha balinganisa olu xinzelelo ngovavanyo olubizwa ngokuba yi-'Tonometry'. Nangona kunjalo, ubukhulu be-cornea budlala indima enkulu apha.
- Ngaphambi kotyando lokususa iiglasi zamehlo: Abantu abaninzi ngoku benza utyando olufana ne-'LASIK' ukuze basuse iiglasi zabo. Olu tyando lubandakanya ukutshintsha imo ye-cornea kusetyenziswa imisebe yelaser. Ngoko ke ngaphambi kokuba wenze olu tyando, kufuneka wazi kakuhle ukuba i-cornea yakho ityebile ngokwaneleyo na ukuze imelane nayo. Ukuba i-cornea incinci, iingxaki ezifana ne-'(corneal ectasia)' zinokwenzeka emva kotyando. Ke ngoko, olu vavanyo ngokuqinisekileyo lwenzelwe ukhuseleko.
- Ezinye iimeko ezinxulumene ne-cornea:Olu vavanyo lukwasetyenziselwa ukujonga iimeko ezichaphazela ubukhulu be-cornea, ezifana ne-'keratoconus' (ukubonakala kwe-cornea okumile okwekhowuni), i-'Fuchs' dystrophy`, kunye ne-'corneal hydrops`.
- Ukulimala kwamehlo: Oku kunceda ukubona ukuba i-cornea yonakele okanye ubukhulu bayo butshintshile na xa kukho ukwenzakala kwamehlo.
- I-Optical Pachymetry (indlela yokungachukumisi) ayinazo iingozi.
- I-Ultrasonic Pachymetry (indlela echukumisa indlebe) ayinazo iingozi ezininzi. Nangona kunjalo, eziIzinto ezinokwenzeka rhoqo.
- Usulelo (oku akunakwenzeka kuba izixhobo zicociwe kakuhle).
- Ukuva ukungonwabi okanye ukucaphuka okuncinci emehlweni.
- Ukunganyamezelani kwamathontsi okuphelelwa ziingcinga.
- Umonakalo wesikhashana kwi-cornea, njengokukrweleka okuncinci kakhulu, ngenxa yokudibana nesixhobo.
- Uvavanyo lwePachymetry luvavanyo olulula kakhulu, olungenabuhlungu, nolukhawulezayo olulinganisa ubukhulu be-cornea yakho.
- Oku kubalulekile ukuze kufunyanwe ngokuchanekileyo i-glaucoma kwaye kuqinisekiswe ukhuseleko ngaphambi kotyando olufana ne-LASIK.
- Kukho iindlela ezimbini zokuvavanya: enye ayichukumisi iliso, enye ibandakanya ukuchukumisa iliso kancinci ngesixhobo esincinci emva kokulifaka iziphazamiso.
- Iziphumo zovavanyo zimbalwa nje. Ngugqirha wakho kuphela onokukunika ingcaciso engcono kakhulu malunga nokuba kuthetha ukuthini na kunye nempilo yamehlo akho. Ngoko ke musa ukutsiba ugqibe kwelokuba ungowakho wedwa.
- Ukuba unemibuzo malunga novavanyo lwakho lwamehlo okanye olu vavanyo, ungathandabuzi ukubuza ugqirha wakho.
Umzekelo, ukuba i-cornea yakho ityebile kunesiqhelo, uxinzelelo olungaphakathi kweliso lunokuba phezulu kunokuba lunjalo ngokwenene. Ngokufanayo, ukuba i-cornea incinci , uxinzelelo lunokuba ngaphantsi kunokuba lunjalo ngokwenene. Ngoko ke ukwazi olu bukhulu kubaluleke kakhulu kugqirha ukuze aqinisekise ukuba unayo na i-glaucoma okanye awunayo.
Ziziphi iindlela zokwenza olu vavanyo?
Zimbini iindlela eziphambili zokwenza olu vavanyo. Zombini zikhawuleza kwaye zilula. Akunyanzelekanga ukuba wenze nantoni na ekhethekileyo ukuze ulungiselele oku.
| Indlela yovavanyo | Kwenzeka njani oku |
|---|---|
| I-Optical Pachymetry | Kule meko, akukho sixhobo sichukumisa iliso lakho. Okufuneka ukwenze kukuhlala phambi komatshini uze ubeke isilevu sakho kunye nebunzi kwindawo ethile kuwo. Ubukhulu bulinganiswa ngemifanekiso ethathwe ngumatshini. I-Optical Coherence Tomography (OCT) yenye indlela enjalo. |
| I-Ultrasonic Pachymetry | Kule nkqubo, kuqala kufakwa amathontsi abangela ukuba ungabi nazintloni esweni lakho. Ukuze ungaziva nto. Emva koko, incam yesixhobo esincinci, esifana nepeni engenazintsholongwane (i-pachymeter) ibekwa kancinci kwi-cornea yakho imizuzwana embalwa. Ubukhulu bulinganiswa kusetyenziswa amaza e-ultrasound . |
Isikhumbuzo esincinci
Ukuba uyazi ukuba uza kunikwa amathontsi anciphisa ubukhali okanye amathontsi avulekayo xa uvavanywa amehlo akho, kukhuselekile ukukhwela nomnye umntu, njengoko la mathontsi enokukwenza ubone izinto ezingafunekiyo okwethutyana.
Ngaba kukho umngcipheko kule nto?
Olu luvavanyo olukhuselekileyo kakhulu.
Ukuba uyaqhubeka nokuba nentlungu yamehlo okanye ukubona izinto ezingacacanga emva kolu vavanyo, fowunela ugqirha wakho ngoko nangoko.
Masifumanise ngeziphumo zovavanyo.
Eyona nto ilungileyo ngolu vavanyo kukuba iziphumo zifumaneka ngoko nangoko. Ugqirha angathetha nawe ngalo mbuzo ngoko nangoko.
Ubukhulu obuqhelekileyo be-cornea ephakathi yeliso eliphilileyo buphakathi kwama -micrometer angama-540 nama-550 .
Kodwa khumbula, eli lixabiso eliqhelekileyo nje. Linokwahluka ngokuxhomekeke kwiminyaka yakho, uhlanga, kunye nezinye iimeko zempilo. Ngoko ke ungakhathazeki ukuba ixabiso lakho lingaphandle kancinci kweli nqanaba. Amehlo akho asenokuba aphilile ngokupheleleyo. Ngugqirha wakho kuphela onokutolika ngokuchanekileyo iziphumo.
Ngokusekelwe kwiziphumo, ugqirha wakho unokugqiba indlela yokunyanga i-glaucoma yakho okanye ukuba ungumntu ofanelekileyo na utyando lwamehlo.
