I-Eye, okanye ngokuthe ngqo, uxinzelelo lwe-intraocular (IOP) luxinzelelo lwe-vitreous kunye neliso lomswakama kwi-capsule yeso ngaphakathi ngaphakathi, okuqinisekisa ukugcinwa kwetoni. Inokuphakanyiswa kwaye kwiimeko ezinqabileyo ezincitshiswayo, ezibangelwa zizifo ezahlukeneyo ze-ophthalmologic okanye iimpawu zobunzima bokuzalwa zesakhiwo kweso. Siza kuthetha ngokuqhelekileyo kwesoxinzelelo lwamehlo, oluqhelekileyo kumntu onempilo.
Yintoni eqhelekileyo yongcinezelo lwamehlo?
Akunakwenzeka ukugweba izibonakaliso zengcinezelo enempilo ngaphakathi kweso ngokungabonakaliyo, kuba kukho iindlela ezahlukeneyo zokulinganisa kunye nezixhobo ezihambelana ngokukhawuleza. Ubungqina babo alunganga ukuthelekisa, kwaye oku kufanele kukhunjulwe ngokubuza umbuzo oqhelekileyo "Yintoni eqhelekileyo yongcinezelo lwamehlo?". Enyanisweni, impendulo yalo mbuzo iya kuba ngumbuzo wokuphendula: "Yiyiphi indlela yoxinzelelo eyalinganiswa?".
Uxinzelelo lwamehlo luhlolwe njani?
Ukucacisa ukunyanzeliswa kwe-intraocular ingaba yindlela ye-manometric, ebandakanya ukungeniswa kwenaliti ekhethekileyo yokulinganisa ekamelweni langaphakathi le-cornea. Ungesabi - le ndlela yenzelwe i-theory, oogqirha ekwenzeni iiklinikhi akayi kukhangela kuyo.
Kwiofisi ye-ophthalmologist, unokubonisa iindlela ezichanekileyo zokulinganisa uxinzelelo lwe-fundus (umgaqo, njengokuba sele siqaphele, kuya kwahluka kwimeko nganye):
- I-Tonometry ngokweMaklakov;
- i-tonometry engaqhagamshelwanga;
- Iimitha zeeonometers;
- I-tonometers yeGoldman;
- Pascal tonometers.
Kuzo zonke izixhobo, imilinganiselo iyafana: ifowuni imanyanisa impendulo yamehlo kumandla asetyenziswa kuyo. I-Ophthalmologists abanamava banokubona iimpawu zokuphambuka kweso siqhamo soxinzelelo lwangaphandle ngaphandle kokulinganisa, nje ngokucinezela iminwe kwamehlo omguli. Nangona kunjalo, ekonyango kwezifo ezinzulu (i- glaucoma , umzekelo), lanisa lo mzobo kwi-millimeter ye-mercury.
Imilinganiselo yokulinganisa
Ngoko, ekuphenduleni umbuzo, ukuba ingcinezelo yamehlo ithathwa njengesiqhelo, siyaqaphela ukuba zonke iindlela ezidweliswe ngaphandle kweyokuqala zibonisa i-IOP yangempela, kwaye ixabiso layo liyashintsha kwimida eyi-10 ukuya kwe-21 mm Hg. Ubugcisa. (indlela yeGoldman kunye neCare: 9 - 21 mm Hg). Ngexesha elifanayo, i-tonometry ngokweMaklakov, e-CIS amazwe yindlela eqhelekileyo yokulinganisa i-IOP, ibandakanya ukufuduka komthamo omkhulu wamanzi kwiinkamelo zamehlo ngethuba le nkqubo, ngoko ke ixabiso lemiqathango yokunyamezela kwamehlo kwabasetyhini kunye namadoda iphezulu kuneendlela zangaphambili. Ngomntu onempilo, isixhobo seMaklakov sibonisa i-IOP ngaphakathi kwe-12 ukuya kwi-25 mm Hg. kwaye olu xinzelelo lubizwa ngokuba yi-tonometric.
Indlela ye-pneumotonometry iphantse iphume, nangona kwamanye amaziko ogqirha isasetyenziswa. Ngokuqhelekileyo i-pneumotonometry ididekile kunye ne-tonometry engaxhunyekanga, nto leyo ibonisa ukufakwa kwe-cornea ngokukhupha komoya.
Ngaba kubuhlungu ukulinganisa i-IOP?
Inkqubo yokulinganisa ixinzelelo lwamehlo isebenzisa indlela kaMaklakov ibandakanya ukubeka isisindo esithile kwisigulane esovulekileyo. Ngaphambi kwangaphambili, i-anesthetic ijojowe emehlweni, kodwa umngcipheko wokusuleleka kwintsebenziswano elandelelanayo ye- conjunctivitis kunye nokungahambi kakuhle iyaqhubeka ihamba neli xesha lingaqhelekanga kodwa liyindlela ephandwayo yokuphanda.
I-tonometry engaxhamliyo inikwe iiklinikhi ezininzi zabucala kwaye ayifaki ukudibanisa ngqo kunye neliso elimnyama. Imitha
I-Tonometers ICare, i-Goldman ne-Pascal nayo ibangela ukuba ubuncinci bezinto ezibuhlungu, nangona kunjalo, ngenxa yezinto eziyinkimbinkimbi kwezi zixhobo kunye neendleko zazo, akuzona zonke iziko lonyango elinokukwazi ukufumana ezo zifundo.
Kufuneka ukuba uqaphele ukuba kunyango lwaluphi na uhlobo lwesifo se-ophthalmic lungcono ukubhekisela kwindlela efanayo ngexesha ngalinye - umzekelo, uxinzelelo lwamehlo kwi-glaucoma aluxhomekekanga ngokungalunganga, ngoko ke akuphosakeli ukwenza amanyathelo kwizinto ezihlukeneyo kwaye ziyingozi.
