Ngaba wakha wajongwa amehlo akho? Emva koko ngequbuliso ufumana uvavanyo apho uvuthela umoya emehlweni akho uze uzive unesizungu? Namhlanje siza kuthetha ngezinye zeendlela zokulinganisa uxinzelelo ngaphakathi kwamehlo akho, kuquka uvavanyo abantu abaninzi abaluqhelileyo. Oku akoyikisi njengoko unokucinga. Enyanisweni, luvavanyo olubaluleke kakhulu lokukhusela ukubona kwakho.
Yintoni iTonometry?
Ngamafutshane, i-tonometry luvavanyo lwezonyango olulinganisa uxinzelelo olungaphakathi kweliso lakho (uxinzelelo lwangaphakathi kweso). Olu lolunye lolona vavanyo lubalulekileyo lokufumanisa imeko ebizwa ngokuba yi-glaucoma. Kukho iindlela ezahlukeneyo zokwenza olu vavanyo. Zonke zikhawuleza kakhulu kwaye azinantlungu.
Kutheni olu vavanyo lubaluleke kangaka?
Iingcali zamehlo zisebenzisa olu vavanyo ikakhulu ukuvavanya nokuxilonga i-glaucoma. Ngokwesiqhelo lwenziwa njengenxalenye yovavanyo lwamehlo oluqhelekileyo. Lwenziwa naxa kukho ukwenzakala kweliso okanye ezinye iimpawu.
Ngamanye amaxesha, oogqirha basebenzisa olu vavanyo ukujonga ukuba uxinzelelo lwamehlo luyanda na njengesiphumo esingesihle samayeza athile owasebenzisayo (uxinzelelo lwamehlo).
Ukuba sele une-glaucoma, kunokufuneka ukuba olu vavanyo lwenziwe rhoqo ukuze kubonwe ukuba unyango lwakho luyasebenza na. Le yeyona ndlela ilungileyo yokuqinisekisa ukuba uxinzelelo lwamehlo akho luphantsi kolawulo.
Oku kulinganisa njani uxinzelelo lwamehlo?
Ngaphakathi kwamehlo ethu, ingakumbi igumbi elingaphambili, lizaliswe lulwelo olubizwa ngokuba yi-aqueous humor . Olu lwelo lunexinzelelo ngaphakathi kweliso, nto leyo elinika imo yalo engqukuva. I-Tonometry ilinganisa uxinzelelo lolu lwelo.
Iyunithi esetyenziselwa ukulinganisa olu xinzelelo yimilimitha yemercury (mmHg). Iyunithi efanayo esetyenziselwa ukulinganisa uxinzelelo lwakho lwegazi isetyenziselwa oku.
Ziziphi iindlela eziphambili ze-tonometry?
Kukho iindlela ezininzi ugqirha wakho anokuzisebenzisa ukulinganisa uxinzelelo lwamehlo akho. Makhe sijonge ukuba zeziphi.
| Indlela yovavanyo | Kalula nje, kwenzeka ntoni? |
|---|---|
| I-tonometry engeyiyo eyokuchukumisa (i-Air-puff) | Olu luvavanyo "lomoya" abantu abaninzi abaluqhelileyo. Umatshini uthumela umoya omncinci kwi-cornea yeliso lakho. Umatshini ulinganisa uxinzelelo olusesweni lakho njengoko umoya uhamba kulo ubuye uphume. |
| I-tonometry ye-applanation | Le yeyona ndlela ichanekileyo ekhoyo. Apha, kufakwa amaconsi eliso athomalalisa iintlungu, kwaye incam yesixhobo esincinci ichukunyiswa kancinci kumphezulu weliso lakho. Uxinzelelo lulinganiswa ngamandla asetyenziswa liliso kumphezulu weliso ukuze lithambe. |
| I-Rebound tonometry | Oku kusebenzisa isixhobo esincinci kakhulu, esimile okwebhola yeplastiki esinencam. Silinganisa uxinzelelo ngesantya esisondela ngaso elisweni, sichukumise umphezulu, size sibuyele umva. Le yindlela ethambileyo nengenabuhlungu. |
Ezinye iindlela
Ukongeza kwezi ndlela ziphambili, kukho ezinye iindlela ezifana ne-'Dynamic contour tonometry' kunye ne-'Electronic indentation tonometry'. Kwakhona, iindlela ezilinganisa uxinzelelo rhoqo ngelixa unxibe ilensi yoqhagamshelwano okwangoku ziphantsi kophando.
Ngaba kufuneka ndilungiselele nantoni na ngaphambi kovavanyo?
Ngokubanzi, akukho nto kufuneka uyenze ngokukodwa ukuze ulungiselele olu vavanyo.
Kodwa kukho into enye encinci. Ukuba kunokwenzeka, musa ukunxiba ihempe okanye i-T-shirt evala intamo yakho ngomhla wovavanyo. Ukuba unxiba ihempe enekhola, yigcine ikhululekile kancinci. Kuba xa intamo yakho ivalekile, uxinzelelo olusesweni lakho lunokunyuka kancinci, olunokubhalwa gwenxa kwingxelo yovavanyo.
Luhlobo luni lwamava olufumanayo xa ubhala uvavanyo?
Oku kunokwahluka kancinci ngokuxhomekeke kwindlela yovavanyo oluthathayo.
- Ukuba usebenzisa i-applanation tonometry, ugqirha wakho uza kubeka amaconsi e-anesthetic kunye nedayi etyheli ebizwa ngokuba yi-fluorescein esweni lakho.
- Kodwa akukho nanye kwezi zinto efunekayo kuvavanyo olungelulo olokuqhagamshelana.
Uninzi lweemvavanyo luthatha imizuzwana embalwa nje. Ngamanye amaxesha ugqirha unokuthatha ukufundwa kabini okanye kathathu ukuze afumane ukufundwa okuchanekileyo. Ngoko ke musa ukucinga, "Owu, ngaba kukho into engalunganga endiyenzileyo?" Yinkqubo eqhelekileyo.
Akukho nanye kwezi mvavanyo ebuhlungu. Ukuba uziva iintlungu, xelela ugqirha wakho ngoko nangoko.
Zithini ixabiso eliqhelekileyo? Yintoni omawuyenze ukuba iziphumo ziyatshintsha?
Uxinzelelo olusesweni lwabantu abaninzi abasempilweni luphakathi kwe -10 kunye ne-21 millimeters ye-mercury (mmHg - 21 mmHg) . Ukuba iziphumo zakho zingaphaya kolu luhlu, kukho izinto ezimbalwa ezinokwenzeka ngokulandelayo.
Ukuba iziphumo ziphezulu kunesiqhelo
Ukuba uvavanyo olulula lubonisa ukuba uxinzelelo lwakho luphezulu, ugqirha wakho uya kuzama ukuluqinisekisa ngendlela echanekileyo ngakumbi, efana ne-applanation tonometry. Ukuba uxinzelelo lwakho luqinisekisiwe ukuba luphezulu, ugqirha wakho unokugqiba ekubeni aqhubeke nokujonga imeko yakho okanye aqale unyango. Uza kucwangciselwa idinga lokulandelela.
Ingxamiseko: Ngamanye amaxesha, imeko engxamisekileyo (i-angle-closure glaucoma) inokwenzeka, apho uxinzelelo olukwiliso lukhula ngequbuliso kakhulu, nto leyo ebangela iintlungu zamehlo kunye nokungaboni kakuhle. Le yingxamiseko yezonyango. Ukuba oku kuyenzeka, kufuneka uye kwi -ETU (iYunithi yoNyango oluNgxamisekileyo) ngoko nangoko. Ngaphandle koko, ungaphulukana nokubona kwakho ngonaphakade.
Ukuba iziphumo zingaphantsi kwexabiso eliqhelekileyo
Uxinzelelo oluphantsi lwamehlo (ngaphantsi kwe-`5 mmHg` okanye `6 mmHg`) nalo luyingxaki. Oku kungonakalisa iliso kwaye kubangele ukulahleka kokubona. Ukuba uxinzelelo lwakho luphantsi, ugqirha wakho uza kukuchazela amanyathelo alandelayo kunye nonyango.
Ndingakwazi ukuqhuba imoto emva kovavanyo?
Le yinto ekufuneka uyicinge. Ukuba ubunovavanyo loxinzelelo lwamehlo kuphela, bekungayi kubakho ngxaki yokuqhuba imoto.
Nangona kunjalo, ukongeza ekulinganiseni uxinzelelo olusesweni, kusetyenziswa ukwandiswa (ukwandiswa kwamehlo) ukuhlola ingaphakathi lelihlo. Ukuba uwandisa amehlo akho ngolu hlobo, unokuba nobunzima bokuqhuba. Usenokuba novelwano ekukhanyeni kwaye usenokungakwazi ukubona izinto ngokucacileyo kufutshane nawe kangangeeyure ezimbalwa.
Kungoko ke, kungcono ukuba umntu akuqhubele okanye asebenzise enye imoto ngomhla wokuhlolwa kwamehlo akho. Kungcono ukucela ingcebiso kugqirha wakho ngale nto.
Umyalezo Wokuya Ekhaya
- I-Tonometry luvavanyo olukhawulezayo nolungenabuhlungu olulinganisa uxinzelelo lwamehlo kwaye lubalulekile ekufumaneni i-glaucoma kwangethuba.
- Uxinzelelo oluqhelekileyo lwamehlo luphakathi kwe-10 mmHg kunye ne-21 mmHg.
- Ukuba iziphumo zakho zingaphaya komlinganiselo oqhelekileyo, ungoyiki kwaye ulandele imiyalelo kagqirha wakho.
- Ukuba ukhe wafaka iyeza lokubulala iintlungu esweni lakho, kuphephe ukulichukumisa okanye ukulihlikihla iliso lakho de kuphele ukuhlaba.
- Ukuba uxinzelelo lunyuka ngequbuliso xa kukho intlungu enkulu emehlweni, yingxaki enkulu leyo. Funa uncedo lwezonyango ngokukhawuleza.
- Xa usiya kuhlolwa amehlo, kungcono ukuba umntu akuqhubele ekhaya, kuba kungasetyenziswa ii-puril ezivulelekileyo.
