Iso, noma ngaphezulu, ukucindezelwa kwe-intraocular (i-IOP) ingcindezi ye-vitreous neyayilitha emzimbeni we-capsule yeso ngaphakathi, okuqinisekisa ukugcinwa kwayo ngezwi. Kungaphakanyiswa futhi ezimweni ezingavamile zinciphise, ezibangelwa izifo ezihlukahlukene ze-ophthalmologic noma izici ezifakwe esibhedlela zeso. Sizokhuluma ngomkhuba wokucindezeleka kweso, okujwayelekile kumuntu onempilo.
Yini evamile yokucindezela kweso?
Akunakwenzeka ukwahlulela izinkomba zokucindezela okunempilo ngaphakathi kweso ngokungalindelekile, ngoba kunezindlela ezihlukahlukene zokulinganisa kanye nezinsimbi ezihambisanayo ngesikhathi esisodwa. Ubufakazi babo abufanele ukuqhathanisa, futhi lokhu kufanele kukhunjulwe ngokubuza umbuzo ovamile "Yini evamile yokucindezela kweso?". Eqinisweni, impendulo yalo mbuzo iyoba ngumbuzo ophikisanayo: "Iyiphi indlela yokucindezela eyayilinganisiwe?".
Ukucindezelwa kweso kuhlolwe kanjani?
Ukucacisa ukucindezela kwangaphakathi kwe-intraocular kungaba indlela ye-manometric, efaka ukufakwa kwesaliti esikhethekile yokulinganisa ekamelweni langaphakathi le-cornea. Ungesabi - le ndlela iwukuthi i-theory kuphela, odokotela emisebenzini yomtholampilo angayisebenzisi.
Ehhovisi le-ophthalmologist, ungaphakamisa izindlela ezingaqondile zokulinganisa ukucindezelwa kwe-fundus (okuvamile, njengoba sesibonile kakade, kuzohluka esimweni ngasinye):
- I-Tonometry ngokusho kweMaklakov;
- i-tonometry engenaxhunyiwe;
- Amanani we-tonometer;
- I-tonometers ye-Goldman;
- Pascal tonometers.
Kuzo zonke izinsimbi, izilinganiso ziyafana: idivaysi inyathelo impendulo yamehlo kumandla asetshenziswe kuyo. Ama-ophthalmologists abanolwazi angathola izimpawu zokuphambuka kwesimiso sokucindezeleka kwamehlo ngisho nangaphandle kokulinganisa, ngokucindezela iminwe esweni lesiguli. Kodwa-ke, ekwelapheni izifo ezinzima (i- glaucoma , isibonelo), fanisa lesi sibalo ngaphakathi kwe-millimeter ye-mercury.
Izici zokulinganisa
Ngakho-ke, ngokuphendula umbuzo, yikuphi ukucindezelwa kweso okubhekwa njengesijwayelekile, siyabona ukuthi zonke izindlela ezibalwe ngaphandle kokuqala zikhombisa i-IOP yeqiniso, futhi inani layo lishintsha ngaphakathi kwemingcele ka-10 - 21 mm Hg. Art. (indlela ye-Goldman ne-ICare: 9 - 21 mm Hg). Ngesikhathi esifanayo, i-tonometry ngokuya kuMaklakov, emazweni e-CIS iyindlela ejwayelekile kakhulu yokulinganisa i-IOP, ihilela ukufuduka komthamo omkhulu wamanzi okuphuma emaceleni ejozi ngenkathi kwenziwa inqubo, ngakho-ke izindinganiso zendlela evamile yokucindezela kwamehlo kwabesifazane nabesilisa ziphakeme kunezindlela zangaphambilini. Ngomuntu onempilo, idivayisi yeMaklakov ibonisa i-IOP ngaphakathi kobubanzi buka-12 kuya ku-25 mm Hg. futhi lokhu kucindezela kubizwa nge-tonometric.
Indlela ye-pneumotonometry isiye yaphela, nakuba kwezinye izikhungo zezokwelapha zisasetshenziswa. Ngokuvamile i-pneumotonometry ididekile ne-tonometry engaxhunyiwe, okusho nokuthi ukufakwa kwe-cornea ngokugeleza komoya.
Ingabe kubuhlungu ukukala i-IOP?
Inqubo yokulinganisa ukucindezeleka kwamehlo ngokusebenzisa indlela yeMaklakov ihilela ukubeka isisindo esikhethekile emehlweni evulekile. Ngaphambi kwalokho, i-anesthetic ijojowe emehlweni, kodwa ingozi yokutheleleka ngokuthuthukiswa okulandelayo kwe- conjunctivitis nokungahambi kahle ihamba nalokhu akuyona indlela yesimanje kodwa isandelwa kakhulu.
I-tonometry engaxhunywanga nayo inikezwa yimitholampilo eminingi yangasese futhi ayifaki ukuxhumana ngokuqondile ngeso elimnandi. Ukulinganisa
I-Tonometers ICare, i-Goldman ne-Pascal nayo ibangela ukungenani okungenani okungajabulisi, kodwa ngenxa yenkimbinkimbi yalezi zinsiza kanye nezindleko ezinkulu, akuzona zonke izikhungo zezokwelapha ezikwazi ukukhokhela lezo zifundo.
Kumele uqaphele ukuthi ekwelapheni noma yisiphi isifo sofuba kungcono ukusebenzisa indlela efanayo njalo-ngokwesibonelo, ukucindezeleka kweso ku glaucoma akubekezeleli ukungalungi, ngakho-ke akulungile ukwenza izilinganiso ezinhlobonhlobo ezihlukile futhi eziyingozi.
