Uyazi ngempela ngalokhu kuhlolwa kwamehlo okukhethekile (i-Pachymetry Test)? Ake sixoxe!

Wake waya kudokotela wamehlo wezwa into efana nokuthi, "Sidinga ukuhlola ukujiya kwe-cornea yakho"? Ungase ucabange ukuthi lokho kuyaxaka kancane. Kuyini lokhu kulinganisa ukujiya kwe-cornea? Yilokho esikubiza ngokuthi ukuhlolwa okwenziwa ngenxa yayo, "Ukuhlolwa kwe-Pachymetry" noma "Ukuhlolwa kwe-Corneal Pachymetry." Kalula nje, kulinganisa ukujiya kwe-"Cornea" yakho, ungqimba olucacile phambi kweso lakho.

Kuyini ukuhlolwa kwe-Pachymetry? Kungani kubalulekile?

Kulungile, ake siqale sibheke ukuthi iyini le `(Cornea)`. Uneso, futhi linolwelwesi olucacile noluqinile kancane ngaphambili, njengengilazi. Njengengilazi yewashi. Yilokhu okusisiza sibone izinto ngokucacile, okungukuthi, kusisiza sigxilise ukukhanya ngokukuqondisa esweni. Kusebenza futhi njengesivikelo esibalulekile esivikela iso ezintweni ezinjengothuli namagciwane.

Ngakho-ke, lokhu kuhlolwa kwe-`(Pachymetry)` kulinganisa ngqo ukuthi i-`(Cornea)` ikhulu kangakanani. Lokhu kuhlolwa okubaluleke kakhulu, ngoba kuye ngokuthi i-`(Cornea)` ikhulu kangakanani, kusiza ukunquma ukuthi unezifo ezithile zamehlo noma cha, kanye nokubona ukuthi uyakufanelekela yini ukwelashwa okuthile.

Enye into, kukhona ukuxhumana okuncane phakathi kwalolu vivinyo lwe-`(Pachymetry)` kanye nolunye uvivinyo olubizwa ngokuthi `(Corneal Topography)`. `(Corneal Topography)` idala imephu yombala ye-`(Cornea)` yakho. Inganikeza ulwazi oluningi mayelana nesimo kanye nobuso be-`(Cornea)`.

Lolu vivinyo lwe-pachymetry lwenziwa nini?

Kunezimo eziningana lapho udokotela wakho wamehlo angase anqume ukwenza lolu vivinyo lwe-"Pachymetry". Ake sibheke ukuthi ziyini:

• I-Glaucoma: Lesi yisifo esingalimaza i-optic nerve futhi siphazamise ukubona ngenxa yokwanda kwengcindezi yangaphakathi kweso (IOP). Ngakho-ke, uma usola ukuthi une-glaucoma, noma uyelashwa ngayo, kubaluleke kakhulu ukukala ubukhulu be-cornea yakho. Lokhu kungenxa yokuthi ubukhulu be-cornea yakho bungathinta imiphumela yokuhlolwa kwe-tonometry okulinganisa ukucindezeleka kwamehlo.
• Ukuhlinzwa kwamaphutha okubuyisa i-refraction: Uma uhlela ukwenza ukuhlinzwa okufana ne-LASIK kokubona eduze noma ukubona kude okudinga ukugqoka izibuko, kuzodingeka nakanjani wenze ukuhlolwa kwe-Pachymetry. Lokhu kwenzelwa ukuthola ukuthi i-cornea yakho ijiyile ngokwanele yini ukwenza ukuhlinzwa.
• Izifo ze-Corneal: Kunezinye izifo ezithinta i-cornea, njenge-corneal hydrops (isimo lapho i-cornea iba namanzi), i-keratoconus (isimo lapho i-cornea ivelela phambili), kanye ne-Fuchs' dystrophy (isimo esithinta ungqimba lwangaphakathi lwe-cornea). Lokhu kuhlolwa kungasiza ekuxilongeni lezi zifo nokuhlela ukwelashwa.
• Ukulimala kwamehlo:Uma kwenzeka okuthile esweni, liphinde lisetshenziswe ukubona ukuthi i-cornea yonakele noma ukujiya kwayo kuthintekile.

Kalula nje, idatha yobukhulu be-cornea etholwe kulolu vivinyo lwe-Pachymetry iwusizo kakhulu ekuqondeni ngokunembile imiphumela yokuhlolwa kwe-Tonometry, okulinganisa ingcindezi esweni lakho.

Lolu vivinyo lwe-pachymetry lwenziwa kanjani? Ingabe kuyinto enkulu?

Akudingeki ulungiselele okuningi ngalolu vivinyo. Ngokuvamile lungaqedwa ngemizuzu embalwa. Kunezindlela ezimbili eziyinhloko zokwenza lokhu:

1. Indlela ye-Optical Pachymetry

Okwenzekayo kulokhu ukuthi wenziwa uhlale esihlalweni phambi komshini. Ikhanda lakho nesilevu kufanele kubekwe endaweni ethile emshinini. Bese umshini uthatha izithombe zeso lakho, uhlaziye lezo zithombe bese ulinganisa ubukhulu be-`(Cornea)`. Kule ndlela, akukho lutho oluthinta iso lakho. Ngezinye izikhathi amasu esimanje anjenge-`(Optical Coherence Tomography - OCT)` ayasetshenziswa kulokhu. Lena indlela esheshayo kakhulu futhi engenabuhlungu.

2. Indlela ye-Ultrasonic Pachymetry

Ngale ndlela, udokotela uqala ngokufaka ithonsi elibangela ukungakhululeki esweni lakho. Lokhu kwenza iso lakho lingabi namizwa okwesikhashana, ukuze ungazizwa ungakhululekile. Ngemuva kwalokho, ithuluzi elihlanzekile, elihlanziwe, elifana nepeni elibizwa ngokuthi i-pachymeter libekwa ngokucophelela ebusweni be-cornea yakho imizuzwana embalwa. Leli thuluzi lisebenzisa amaza e-ultrasound, angamaza omsindo avame kakhulu, ukukala ubukhulu be-cornea yakho. Ngokuvamile, ubukhulu bulinganiswa maphakathi ne-cornea, kodwa ngezinye izikhathi nezinye izindawo zingalinganiswa.

Okubalulekile: Uma wazi ukuthi uzothola amaconsi amehlo ngesikhathi sokuhlolwa kwamehlo akho, kungcono ukuthi omunye umuntu akushayele esikhundleni sokushayela. Amanye amaconsi amehlo angabangela ukuthi umbala omnyama uvuleke, okungabangela ukufiphala kombono. Amaconsi okufiphaza amehlo ngezinye izikhathi angaba nomthelela omncane ekuboneni.

Ingabe zikhona izingozi ngalolu vivinyo?

Lokhu kungaba yinto oyicabangayo nawe. Ake sibone.

• Indlela ye-Optical Pachymetry: Njengoba iso lingathinteki kule ndlela, azikho izingozi esingakhuluma ngazo. Iphephile kakhulu.
• I-Ultrasonic Pachymetry: Le ndlela futhi ayinazo izingozi ezinkulu, kodwa kunezinto ezimbalwa ezincane ezingenzeka kaningi kakhulu:
• Kunethuba elincane lokutheleleka kwamehlo (yingakho kusetshenziswa imishini ehlanzekile).
• Amehlo angase abe bomvu kancane, avuvuke, noma alume (ukucasuka kwamehlo).
• Abanye abantu bangase babe nokusabela okuncane kokungezwani komzimba namaconsi amehlo angasebenzi kahle.
• Uma i-Pachymeter icindezelwa esweni, ngezinye izikhathi ingashiya umkrwelo omncane, wesikhashana ebusweni be-Cornea. Lokhu kuzophola ezinsukwini ezimbalwa.

Into ebaluleke kakhulu ukuthi uma uhlangabezana nanoma yiziphi izinkinga zokubona, ubuhlungu bamehlo, noma yini enye engavamile ngemva kokuhlolwa kwamehlo, kufanele wazise udokotela wakho wamehlo ngokushesha.

Uthola kanjani imiphumela yokuhlolwa? Ikutshelani?

Ingxenye engcono kakhulu ukuthi uthola imiphumela ngokushesha ngemva kokuhlolwa. Udokotela wakho angakhuluma nawe ngayo khona lapho.

Ngokusho kocwaningo olwenziwe e-United States, ubukhulu obujwayelekile bomzimba womuntu ophilile (i-Cornea) (i-Central Corneal Thickness - CCT) buphakathi kwama-micrometer angu-540 no-550 (ama-micrometer) noma ama-microns (ama-microns). Kodwa lokhu kuyinani elimaphakathi nje, khumbula. Udokotela wakho ngeke acabangele leli nani kuphela, kodwa futhi nezinye izici eziningi, njengobudala bakho, impilo yakho iyonke, nokuthi unezinye izifo zamehlo, lapho enquma ukuthi uzothini kule miphumela. Ngakho-ke, noma ngabe ubukhulu bakho (i-Cornea) bungaphandle kwaleli banga elijwayelekile, amehlo akho angase abe nempilo enhle.

Uma imiphumela ingavamile, yini okufanele ngiyenze ngokulandelayo?

Cabanga ukuthi imiphumela yakho yokuhlolwa kwe-Pachymetry ayikho phakathi kwebanga elijwayelekile. Kwenzekani-ke? Udokotela usebenzisa le miphumela ukuze anqume ukuthi yini okufanele ayenze ngokulandelayo.

• Nge-Glaucoma: Uma une-glaucoma, lolu lwazi lokujiya kwe-cornea lungasiza ekunqumeni ukuthi usabela kanjani ekwelashweni kwakho nokuthi ingabe ukwelashwa kwakho kuyadingeka yini.
• Ngokuhlinzwa kwamehlo: Uma ulungiselela ukuhlinzwa okufana ne-`(LASIK)`, ubukhulu be-`(Cornea)` bubaluleke kakhulu. Ngoba, uma i-`(Cornea)` ingajiyile ngokwanele ukwenza ukuhlinzwa, isimo esibizwa ngokuthi i-`(Corneal ectasia)` singase senzeke ngemva kokuhlinzwa. Lokho kusho ukuthi i-`(Cornea)` iba buthakathaka futhi ivele phambili. Lokho kungaba nomthelela omkhulu ekuboneni. Ngakho-ke, lokhu kuhlolwa kwenziwa ngaphambi kokuhlinzwa ukuze kuncishiswe leyo ngozi.

Kusho ukuthini uma i-cornea yakho ijiyile?

Ama-cornea abanye abantu angase abe mancane kunokujwayelekile. Kusho ukuthini lokho?

• Ngokuvamile, kutholakale ukuthi abantu abane-cornea ejiyile basengozini encane yokuba ne-glaucoma.
• Futhi, uma kulinganiswa umfutho wamehlo (IOP) womuntu one-cornea ejiyile, kungabonisa inani eliphakeme kunengcindezi yangempela. Lokho kusho ukuthi, ngenxa yokuthi i-cornea ijiyile, i-pressure gauge ingase inikeze ukufundwa okungalungile.

Ngakho-ke, ngokwazi ukujiya okuqondile kwe-cornea yakho, udokotela wakho angenza ukuhlolwa okunembile kokucindezeleka kwamehlo akho futhi akuxilonge ngokunembile.

Ngakho-ke, yiziphi izinto okufanele sizikhumbule kule ndaba?

Kulungile, ngithemba ukuthi usunombono omuhle mayelana ne-`(Pachymetry Test)`. Kalula nje, lokhu ukuhlolwa okungenabuhlungu, okusheshayo okubaluleke kakhulu empilweni yamehlo akho.

Khumbula:Uma udokotela wakho wamehlo encoma ukuhlolwa kwe-Pachymetry, kusho ukuthi badinga ukwazi ukujiya kwe-cornea yakho, bahlole ngokunembile ukucindezeleka kwakho kwangaphakathi kweso (i-IOP), futhi banqume ukuthi ungumuntu ofanele yini ukuhlinzwa kwamehlo noma ukuhlela ukwelashwa kwezimo ezifana ne-glaucoma. Lesi esinye isinyathelo esingasiza ekuvikeleni umbono wakho.

Ngakho-ke, kubalulekile ukulandela iseluleko sezokwelapha. Uma unemibuzo, ungesabi ukubuza udokotela wakho.
