Wake wahlolwa amehlo ngudokotela wabe esekutshela ukuthi ulinganise ubukhulu be-cornea yakho? Kungenzeka ukuthi utshelwe nokuthi wenze 'i-Pachymetry Test'. Abantu abaningi bazizwa bengajwayelekile uma bezwa leli gama, becabanga ukuthi liyisilingo esikhulu noma ukuthi lizolimaza. Ngakho-ke namuhla, ake sixoxe ngokuthi iyini le Pachymetry Test, ukuthi kungani yenziwa, nokuthi kufanele uyesabe yini.
Kalula nje, luyini lolu vivinyo lwe-Pachymetry?
Kalula nje, i-Pachymetry Test iyisivivinyo esilinganisa ubukhulu be-cornea yakho. Manje ungase uzibuze, "Iyini le cornea?"
I-cornea iyi-membrane encane, esobala ngokuphelele, efana newashi ngaphambili kweso lethu. Inemisebenzi emibili eyinhloko:
1. Kusisiza sibone ngokucacile ngokugxila ekukhanyeni okungena esweni.
2. Ukuvikela amehlo othulini namagciwane.
Ngakho-ke, lolu vivinyo lwe-Pachymetry lulinganisa ubukhulu be-cornea ngama-micrometer. Lokhu kunikeza udokotela ulwazi olubaluleke kakhulu mayelana nempilo yeso. Ngezinye izikhathi lolu vivinyo lwenziwa kanye nokuhlolwa okubizwa ngokuthi i-'Corneal Topography', okudala imephu yobuso be-cornea.
Kukuziphi izimo lapho kwenziwa khona lokhu kuhlolwa?
Udokotela angase acele lokhu kuhlolwa ngezizathu eziningana. Ezivame kakhulu yilezi:
- Ukuxilongwa Nokwelashwa Kwe-Glaucoma: I-Glaucoma yisifo lapho ingcindezi engaphakathi kweso (Intraocular Pressure - IOP) ikhuphuka khona futhi ingalimaza i-optic nerve. Odokotela balinganisa le ngcindezi ngokuhlolwa okubizwa ngokuthi i-`Tonometry`. Kodwa-ke, ukujiya kwe-cornea kudlala indima enkulu lapha.
- Ngaphambi kokuhlinzwa kokususwa kwengilazi yamehlo: Abantu abaningi manje sebehlinzwa njenge-'LASIK' ukuze balahle ingilazi zabo. Lokhu kuhlinzwa kuhilela ukushintsha isimo se-cornea kusetshenziswa imisebe ye-laser. Ngakho-ke ngaphambi kokuhlinzwa, udinga ukwazi kahle ukuthi i-cornea yakho ijiyile ngokwanele yini ukuze imelane nayo. Uma i-cornea incane, izinkinga ezifana ne-'(corneal ectasia)' zingase zenzeke ngemva kokuhlinzwa. Ngakho-ke, lokhu kuhlolwa kwenziwa ngokuqinisekile ukuze kuphephe.
- Ezinye izimo ezihlobene ne-cornea:Lokhu kuhlolwa kusetshenziselwa futhi ukuqapha izimo ezithinta ukujiya kwe-cornea, njenge-'keratoconus' (ukuphuma kwe-cornea okumise okwekhoni), i-'Fuchs' dystrophy', kanye ne-'corneal hydrops'.
- Ukulimala kwamehlo: Lokhu kusiza futhi ukubona ukuthi i-cornea yonakele noma ukujiya kwayo kushintshile yini uma kwenzeka ukulimala kwamehlo.
- I-Optical Pachymetry (indlela yokungathintani) ayinazo izingozi.
- I-Ultrasonic Pachymetry (indlela ethinta indlebe) inezingozi ezimbalwa kakhulu. Kodwa-ke, leziIzinto ezingenzeka kaningi kakhulu.
- Ukutheleleka (lokhu akunakwenzeka ngoba imishini ihlanzwe kahle).
- Ukuzwa ukungakhululeki okuncane noma ukucasuka esweni.
- Ukungezwani komzimba okuthile namaconsi okubangela ukuba nomuzwa wokungezwani.
- Umonakalo wesikhashana ku-cornea, njengokuklwebheka okuncane, ngenxa yokuthintana nedivayisi.
- Ukuhlolwa kwe-Pachymetry kuyindlela elula kakhulu, engenabuhlungu, futhi esheshayo elinganisa ubukhulu be-cornea yakho.
- Lokhu kubalulekile ukuze kutholakale ngokunembile i-glaucoma futhi kuqinisekiswe ukuphepha ngaphambi kokuhlinzwa okufana ne-LASIK.
- Kunezindlela ezimbili zokuhlola: enye ayithinti iso, kanti enye ihilela ukuthinta iso kancane ngethuluzi elincane ngemva kokulifaka izinzwa.
- Umphumela wokuhlolwa umane nje uyinombolo. Udokotela wakho kuphela ongakunikeza incazelo engcono kakhulu yokuthi kusho ukuthini kanye nempilo yamehlo akho. Ngakho-ke ungasheshi ufinyelele eziphethweni ngakho wedwa.
- Uma unemibuzo mayelana nokuhlolwa kwamehlo akho noma lokhu kuhlolwa, ungangabazi ukubuza udokotela wakho.
Isibonelo, uma i-cornea yakho ijiyile kunokujwayelekile, ingcindezi engaphakathi kweso ingaba phezulu kunalokho eyikho ngempela. Ngokufanayo, uma i-cornea incane , ingcindezi ingaba phansi kunalokho eyikho ngempela. Ngakho-ke ukwazi lobu bukhulu kubaluleke kakhulu kudokotela ukuze anqume ukuthi une-glaucoma noma cha.
Yiziphi izindlela zokwenza lokhu kuhlolwa?
Kunezindlela ezimbili eziyinhloko zokubhala lesi sivivinyo. Zombili zishesha kakhulu futhi zilula. Awudingi ukwenza lutho olukhethekile ukuze ulungiselele lokhu.
| Indlela yokuhlola | Kwenzeka kanjani |
|---|---|
| I-Optical Pachymetry | Kulokhu, akukho mishini ethinta iso lakho. Okudingeka ukwenze nje ukuhlala phambi komshini bese ubeka isilevu sakho nebunzi endaweni ethile kuwo. Ubukhulu bulinganiswa ngezithombe ezithathwe umshini. I-Optical Coherence Tomography (OCT) ingenye indlela enjalo. |
| I-Ultrasonic Pachymetry | Kule nqubo, kuqala kufakwa amaconsi aqeda izinhlungu esweni lakho. Ngakho ngeke uzwe lutho. Ngemuva kwalokho, isihloko sethuluzi elincane, elifana nepeni elihlanzekile (i-pachymeter) sibekwa ngobumnene kakhulu ku-cornea yakho imizuzwana embalwa. Ubukhulu bulinganiswa kusetshenziswa amaza e-ultrasound . |
Isikhumbuzo esincane
Uma wazi ukuthi uzonikezwa amaconsi okufaka izinzwa noma amaconsi okukhulisa amehlo ukuze uhlolwe amehlo akho, kuphephile ukugibela nomunye umuntu, njengoba la maconsi angafiphaza umbono wakho okwesikhashana.
Ingabe kukhona ingozi kulokhu?
Lolu vivinyo luphephile kakhulu.
Uma uqhubeka nokuba nobuhlungu bamehlo noma ukubona okufiphele ngemva kwalokhu kuhlolwa, shayela udokotela wakho ngokushesha.
Ake sithole ngemiphumela yokuhlolwa.
Into engcono kakhulu ngalolu vivinyo ukuthi imiphumela itholakala ngokushesha. Udokotela angakhuluma nawe ngakho ngokushesha.
Ubukhulu obujwayelekile be-cornea ephakathi kweso eliphilile buphakathi kwama -micrometer angu-540 no-550 .
Kodwa khumbula, lokhu kumane kuyinani elimaphakathi. Lingahluka kuye ngeminyaka yakho, uhlanga, kanye nezinye izimo zempilo. Ngakho ungakhathazeki uma inani lakho lingaphandle kwaleli banga. Amehlo akho angase abe nempilo ephelele. Udokotela wakho kuphela ongachaza umphumela ngokunembile.
Ngokusekelwe emiphumeleni, udokotela wakho anganquma ukuthi angayilapha kanjani i-glaucoma yakho noma ukuthi ungumuntu ofanelekile yini ukuhlinzwa kwamehlo.
