Tonometry ke teko ea ho lekanya khatello mahlong a hau, a bitsoang khatello ea mahlo a "intraocular eye" (IOP). Ho lekanya khatello ea mahlo ke karolo ea bohlokoa ea tlhahlobo ea mahlo . Haeba khatello ea mahlo a hao e feta ho tloaelehileng, u ka ba kotsing ea ho ntlafatsa mafu a mahlo a kang glaucoma . Matšoao a mahlo a phahameng a ka senya maqheqha a thata a ka morao a leihlo la hao, ka linako tse ling a baka bofofu.
Tonometer ke sesebelisoa se khethollang khatello ea li-intraocular ka ho lekanya ho hanyetsa ha cornea ea hau ho isa holimo. Ngaka ea hau ea mahlo e ka sebelisa e 'ngoe ea mekhoa e mengata ho lekanya khatello mahlong a hau.
Goldman Tonometry
Toneometer e tloaelehileng ka ho fetisisa eo litsebi tsa tlhokomelo ea mahlo li e sebelisang ke tonomone ea goldman ea tonometer e entsoeng ke Zeiss. Hangata tonometer ea Goldman e khomaretsoe nyenyane ea litebelisoa tsa lebone. Mahlaseli a mahlo a mahlahahlaha a kenya letsoho mahlong a hao, a lateloa ke tee e nyenyane ea dae ea fluorescein. Leseli le leputsoa la cobalt ebe le khantša flurorescein le tonometer. Sesebelisoa se senyenyane se hatelloa ka leihlong la hao, se kenyelletsa cornea. Khatello eo cornea e phunyeletsang tonometer e nkoa ka lik'hilograma tse mercury, e fa ngaka ea hau ea mahlo nomoro e ka e ngolang le e bapisoang le eona selemo le selemo.
E seng ea Contact Tonometry
Tsela e sa amaneng le tonometry (NCT) e atisa ho bitsoa "tlhahlobo ea moea ".
Batho ba bangata ba khetha mofuta ona oa tonometry hobane ha o ame ho ama leihlo. Ho e-na le hoo, moea o bonolo o sebelisoa ho pata cornea. NCT tonometry ha e nkoe e nepahetse joaloka Goldman tonometry empa e fana ka tsela e sebetsang haholo le e potlakileng ea ho lekanya khatello ea mahlo ho bana kapa batho ba baholo ba nang le kutloelo-bohloko.
Electronic Tonometry
Toneometry ea elektronike e bua ka lisebelisoa tse tsamaisoang ka letsoho, mochine o sebelisoang ke ngaka ea mahlo ho tloha ka kamoreng ho ea ho e 'ngoe ho hlahloba khatello ea mahlo Ha u ngola pene ea ho ngola, tonometer ea mobile e bonolo ebile e sebelisoa kapele ho cornea ea hau. Ngaka ea hau e ka 'na ea fumana lipalo tse tharo tse balang e le hore u fumane tekanyo e nepahetseng. Toneometry ea elektronike ha e nkoa e le ea tšeptjoang kapa e nepahetseng joaloka Goldman tonometry empa e na le thuso e kholo bakeng sa ngaka e phathahaneng.
Schiotz Tonometry
Schiotiz tonometry ke mofuta oa indentation ea tonometry. Tsela ea tonometer ea khatello ea mali e hatella khatello ea mahlo ka ho lekanya botebo ba ho holofala ho bakoang ke pente e nyenyane ea tšepe ha e ntse e le holim'a cornea. Litsebi tsa kajeno tsa tlhokomelo ea mahlo ha li sebelise indentation tonometry. Ka linako tse ling tonometry ea limela e sebelisoa liofising tse tloaelehileng tsa lingaka le masole.
Khatello ea mahlo e tloaelehileng e fapana pakeng tsa batho. Haeba khatello ea mahlo a hao e phahametse tloaelehileng, kotsi ea ho hlahisa glaucoma e ka eketseha.
