I-Tonometry: Ake sixoxe ngalokhu kalula!

Wake wahlolwa amehlo? Ngesikhathi wenza kanjalo, cishe wahlolwa lapho wanikezwa khona ifasitela elincane lomoya noma ithuluzi elincane lokubuka iso lakho. Yilokho esivame ukukubiza ngokuthi i-tonometry. Lokhu kuhlolwa okubaluleke kakhulu, ikakhulukazi ekutholakaleni kusenesikhathi kwezimo zamehlo njenge-glaucoma. Ngakho-ke, ake sixoxe ngalokhu ngemininingwane ethe xaxa namuhla, akunjalo?

Kuyini i-tonometry? Kalula nje...

I-Tonometry ukuhlolwa kwamehlo okukhethekile okulinganisa ingcindezi engaphakathi kweso lakho, okubizwa ngokuthi ingcindezi yangaphakathi kweso . Kufana nokuhlola ingcindezi yegazi lakho, kodwa kuqondene ngqo namehlo akho. Kungenye yezivivinyo ezibaluleke kakhulu zokuxilonga i-glaucoma. Kunezindlela eziningana zokwenza lokhu kuhlolwa. Zonke ziyashesha futhi azibuhlungu.

Lolu vivinyo lwenziwa nini?

I-Tonometry ivame ukwenziwa ochwepheshe bamehlo, okungukuthi odokotela bamehlo kanye nodokotela bamehlo. Kunezizathu eziningana zalokhu:

• Hlola futhi uhlole i-glaucoma: Lena imbangela eyinhloko. I-Glaucoma yisifo lapho ukucindezeleka okukhulu emehlweni konakalisa khona i-optic nerve futhi kungaholela ekulahlekelweni kokubona.
• Njengengxenye yokuhlolwa kwamehlo okuvamile: Uma uhlolwa amehlo njalo, lokhu kungaba yingxenye yalokho kuhlolwa.
• Uma kukhona ukulimala noma izimpawu ezingaba khona emehlweni: Lokhu kuhlolwa kungenziwa uma kwenzeka okuthile esweni, noma uma ubona okuthile okuhlukile emehlweni akho kunokujwayelekile.
• Uma uthatha imithi ethile: Uma uthatha imithi yesinye isimo, lokhu kwenziwa futhi ukuhlola ukuthi ukucindezeleka kwamehlo kuyanda yini njengomphumela ongemuhle walowo muthi (umfutho wegazi ophakeme wamehlo).
• Ukuqapha ukwelashwa kwabantu abane-glaucoma: Uma usuvele une-glaucoma, lokhu kuhlolwa kwenziwa njalo ukuze kubonakale ukuthi ukwelashwa kwakho kuyasebenza yini nokuthi ukucindezeleka kwamehlo akho kuyalawulwa. Ngezinye izikhathi odokotela batusa amadivayisi ongawasebenzisa ukukala ukucindezeleka kwamehlo akho ekhaya.

Lolu vivinyo (lwe-Tonometry) lusebenza kanjani?

Kulula kakhulu. I-Tonometry ilinganisa ingcindezi ekamelweni elingaphambili leso lakho. Leli gumbi litholakala ngemuva kwe-cornea. Liqukethe uketshezi olubizwa ngokuthi i-aqueous humor. Ingcindezi evela kulolu ketshezi yiyo egcina amehlo ethu eyindilinga. Iyunithi yokulinganisa yalolu xinzelelo ingamamilimitha e-mercury (mmHg) . Yiyunithi efanayo esetshenziselwa ukukala ingcindezi yegazi.

Manje ake sibone ukuthi yiziphi izindlela ezahlukene zokwenza lokhu kuhlolwa.

Yiziphi izindlela ezahlukene ze-tonometry?

Udokotela wakho wamehlo angasebenzisa izindlela eziningana ukwenza lokhu kuhlolwa:

• I-tonometry ye-applanation:Igama elithi "Applanation" lisho "ukuthamba." Kule ndlela, idivayisi encane, efana nediski eyisicaba icindezelwa ngobumnene ebusweni belihlo lakho. Lokhu kulinganisa ukuthi udinga ukufaka ingcindezi engakanani ngaphambi kokuba ubuso belihlo lakho buqale ukuthamba. Lokhu kuthiwa kuyindlela enembe kakhulu . Isetshenziselwa ukuqinisekisa imiphumela engavamile evela kwezinye izindlela.
• Ukuqapha okuqhubekayo: Kule ndlela, ugqoka inzwa, njengelensi yokuxhumana, esweni lakho. Abacwaningi baphenya futhi ngale nzwa egqokwayo, kanye nendlela yokufaka inzwa ngokuhlinzwa esweni.
• I-Dynamic contour tonometry: Lawa madivayisi ane-sensor tip encane ethinta iso, kodwa ayenzi i-inbot.
• I-tonometry yokugoba nge-elekthronikhi: Imishini esetshenziswa kule ndlela ine-probe encane ethintwa ebusweni beso kuze kube yilapho kudalwa ukugoba nge-indent.
• I-Non-contact tonometry: Yilokhu abantu abaningi abakwaziyo ngokuthi ukuhlolwa kwe-"air puff". Lawa madivayisi aqondisa umfudlana womoya ngokumelene ne-cornea yeso lakho. Njengoba umoya ushaya futhi ubuyela emuva, alinganisa izinguquko ezincane esimweni se-cornea ezenzeka phakathi nemizuzwana embalwa. Ama-air puff tonometer asebenzisa i-puff encane yomoya, kuyilapho ama-ocular response analyzer esebenzisa i-stream yomoya.
• I-Rebound tonometry: Kule ndlela, into encane efana nebhola lepulasitiki ixhunyaniswa ngokushesha neso bese ima ngokushesha nje lapho ithinta indawo. Idivayisi ilinganisa ingcindezi yangaphakathi kweso lapho ibhola lithinta indawo kancane futhi ngaphandle kobuhlungu. Amanye amadivayisi asebenzisa le ndlela anganconywa ukuthi uwasebenzise ekhaya.

Cabanga nje, zonke lezi zindlela zenzelwe ukukala ukucindezeleka kwamehlo ngokunembe ngangokunokwenzeka, ngaphandle kokukubangela ukungakhululeki noma ubuhlungu.

Kufanele silungiselele kanjani lokhu?

Ngokuvamile akukho ukulungiselela okukhethekile okudingekayo ukuze kuhlolwe i-tonometry. Okuwukuphela kwento okufanele uyenze ukungagqoki lutho oluvimba intamo yakho (isb. ikhola eqinile) ngesikhathi sokuhlolwa. Uma kungenzeka, gqoka ihembe elihlukile noma ukhulule ikhola kancane. Ukucindezela okuzungeze intamo yakho okuvela ezingutsheni kungabangela ukuthi ukufundwa kwengcindezi yangaphakathi kwamehlo kubonakale kuphakeme kancane.

Yini okufanele uyilindele lapho ubhala isivivinyo?

Lokho okutholayo ngesikhathi sokuhlolwa kwe-tonometry kungahluka kancane kuye ngendlela esetshenzisiwe. Isibonelo, uma wenza i-applanation tonometry, udokotela wakho uzofaka i-anesthetic kanye nedayi ebizwa ngokuthi i-fluorescein emehlweni akho. Kodwa-ke, ezinye izindlela eziningi, njenge-non-contact tonometry, azidingi noma iyiphi yalezi.

Iningi lezindlela ezisetshenziswayo lithatha imizuzwana embalwa kuphela ukwenza isivivinyo. Ukuze uthole imiphumela emihle kakhulu kulezi zindlela ezisheshayo, kungcono ukuthatha izilinganiso eziningana bese uzilinganisa. Ngakho-ke ungamangali uma udokotela wakho ethatha izilinganiso eziningana noma ecabanga ukuthi wenze into engalungile. Ezinye izindlela, njenge-applanation tonometry, zingathatha imizuzu embalwa. Uchwepheshe wakho wokunakekelwa kwamehlo uzokutshela okwengeziwe ngalokho ongakulindela ngesikhathi sokuhlolwa.

Ngemva kokuhlolwa?

Udokotela angakutshela imiphumela ngokushesha nje lapho ukuhlolwa sekuqediwe.

Uma unikezwe amaconsi amehlo abulala izinzwa, ungafaki lutho emehlweni akho kuze kube yilapho ukungabi namizwa kuphelile. I-anesthetic izokuvimbela ukuthi ungezwa ubuhlungu, ngakho-ke kungenzeka ukuthi ulimaze amehlo akho ngenkathi engaboni kahle.

Ingabe lokhu kuyalimaza?

I-Tonometry ayibuhlungu , yize indlela esetshenziswayo ingase ihilele ukuthintana nenhlamvu yeso lakho. Uma uzwa ubuhlungu ngesikhathi sokuhlolwa, tshela udokotela wakho wamehlo. Ungambuza futhi ngobuhlungu, ukuthi buzohlala isikhathi esingakanani, nokuthi yini engenziwa ngakho.

Kufanele libe yini izinga lomfutho wegazi elijwayelekile?

Kubantu abaningi, ibanga elijwayelekile libhekwa njengeliphakathi kuka -10 mmHg no-21 mmHg . Uma imiphumela yakho ingaphandle kwaleli banga elijwayelekile, kunezinto ezimbalwa ezingase zenzeke.

Kuthiwani uma imiphumela iphezulu kakhulu?

Uma ukuhlolwa okulula kubonisa ukuthi umfutho wakho uphezulu, udokotela wakho wamehlo cishe uzoncoma ukuhlolwa kwe-applanation tonometry ukuqinisekisa ukulinganiswa. Uma umfutho wakho usephezulu ngenxa ye-applanation tonometry, udokotela wakho angase awuqaphe eduze noma asikisele izinketho zokwelapha. Bangase futhi bakuyise ukuze uhlolwe njalo.

Udokotela wakho wamehlo angase akucebise nokuthi ulinganise umfutho wamehlo akho ekhaya. Uma kunjalo, qiniseka ukuthi ubuza ukuthi wenzeni uma ukufundwa kwakho kungaphandle kwesilinganiso esijwayelekile. Uma ukufundwa kwakho kuphakeme kancane kunokuvamile, ungadinga ukulandelwa ngudokotela onguchwepheshe. Kodwa-ke, uma ukufundwa kwakho kuphakeme kakhulu kunalokho, ungadinga usizo lwezokwelapha oluphuthumayo .

Okubalulekile: Ukwanda kwengcindezi esweni ngenxa ye-glaucoma evalekile yisimo esiphuthumayo sezokwelapha esidinga ukwelashwa ngokushesha. Uma singelashwa ngokushesha, lesi simo singaholela ekulimaleni kwamehlo kanye nokulahlekelwa umbono unomphela.

Ezinye izinyathelo zingase zihluke kuye ngesimo sakho kanye nezidingo zakho. Uchwepheshe wakho wokunakekelwa kwamehlo uzokutshela okwengeziwe ngalokho ongakulindela kuye ngesimo sakho.

Kuthiwani uma imiphumela iphansi kakhulu?

Ukucindezeleka okuphansi kwamehlo nakho kuyindaba ekhathazayo, njengoba kungalimaza iso futhi kubangele ukulahlekelwa umbono. Ukucindezeleka okuphansi kwamehlo ngokuvamile kungaphansi kuka-5 mmHg noma u-6 mmHg . Uma ukucindezeleka kwamehlo akho kuphansi kakhulu, uchwepheshe wamehlo akho uzokhuluma nawe ngezinketho zokwelapha kanye nokuvakasha okulandelayo ukuze aqaphe impilo yamehlo akho.

Ngingakwazi yini ukushayela imoto ngemva kokuhlolwa?

Ungase ukwazi ukushayela noma ungabi nakho ukushayela ngemva kokuhlolwa komfutho wamehlo. Lokhu kuncike ezintweni eziningana. Isici esibalulekile ukuthi ngabe abafundi bakho bavulwe yini (ekuhlolweni kwamehlo okuvamile, abafundi bavulwe ngemva kokuhlolwa kwe-tonometry). Ukukhulisa amehlo akho kungakwenza uzwele kakhulu ekukhanyeni, futhi kungaba nzima ukubona noma ukufunda izinto eduze. Le miphumela ivame ukuhlala amahora ambalwa.

Ochwepheshe bamehlo bavame ukuba nezibuko ezilahlwayo ongazigqoka ngemva kokuhlolwa (uma ugqoka izibuko, lezi zibuko zingagqokwa phezu kwezibuko zakho). Lezi zibuko zingakusiza ukuthi ubone futhi uhlale ukhululekile ngokunciphisa ukukhanya nokukhanya kokukhanya. Abantu abaningi bathola ukuthi basengakwazi ukushayela ngemva kokukhulisa amehlo abo. Kodwa-ke, uma unokungabaza ngokuthi ungashayela yini ngemva kokuhlolwa kwamehlo, kungumqondo omuhle ukucabangela ezinye izindlela zokuhamba ohambweni lwakho oluya nolubuya kuchwepheshe wamehlo .

Okokugcina, izinto okufanele uzikhumbule

Yebo, ungase ungawuthandi umoya noma umqondo wokubamba idivayisi ephathwayo eduze kwamehlo akho. Kodwa kunesizathu esihle salokho. I-Glaucoma yisimo esivamile, kodwa ukucindezeleka okuphezulu esweni okubangela lokhu kungatholakala ngaphambi kokuba ubhekane nezimpawu noma umonakalo ohlala njalo.

Uma unengcindezi ephezulu emehlweni akho, uchwepheshe wakho wamehlo ulapha ukuzokusiza. Ukusekelwa kwabo kungaba yilokho kanye okudingayo ukulawula ingcindezi engaphakathi kwamehlo akho. Kungasiza futhi ekunciphiseni ukucindezeleka okuzwayo ngempilo yakho iyonke yamehlo. Ngakho-ke, kubalulekile ukuhlolwa amehlo akho njalo, ngaphandle kokwesaba noma ubuvila.
