Tindlela amehlo biomicroscopy

Biomicroscopy iso - yindlela mihla diagnostic zophando oluqhutywa usebenzisa isixhobo okhethekileyo - isibane noqhoqhoqho. isibane Special iquka umthombo wokukhanya, nto leyo ukutshintsha ukugqama, kunye ngemicroscope eyodwa. Ukusebenzisa le ndlela yokuqhuba uphando biomicroscopy of cipande ingxenye amehlo.

ubungqina

Le ndlela isetyenziswa ngokusebenzisana kunye uvavanyo umbono zamehlo umgangatho kunye lokufunyaniswa fundus. Biomicroscopy kwakhona isicelo ukuba umntu ekrokrela ebusweni ngezifo iso. Ezinxaxhileyo apho ugqirha imisela le saveyi ziquka: conjunctivitis, nangokurhala, amaqumrhu amazwe iliso, nangezilonda, keratitis, uveitis, dystrophies, opacities, cataract kunye nezinye. Biomicroscopy le iliso eboniswe iimviwo unyango phambi nasemva-zoqhaqho esweni. Kwakhona, le nkqubo iya kuqeshwa njengenyathelo ezongezelelweyo izifo kwinkqubo yonyango.

Njani na indlela?

Inkqubo eye biomicroscopy eendaba a ukuvise intlungu kumguli. Umntu uthi kuphela msebe wokukhanya kwaye ithwala isicelo gqirha. Inkqubo ayidingi uqeqesho olulodwa kwaye ngokukhawuleza. Biomicroscopy lwenziwa kwigumbi mnyama. Kugqirha wamehlo uyaqinisekisa ukuba umntu uthathe indawo ekunene: kwesilevu ivuliwe ngenkxaso eyodwa intloko ungqiyame ibunzi lakhe indawo kwi bar. Xa isigulane ibekwe kakuhle phezu kwentloko koseko, wamehlo uqala ukufunda le nkqubo. Ugqirha lutshintsha indlela kunye nokuqaqamba umqadi ukukhanya, lo gama ukugcina iliso ijwabu reaction neenguqu ukhanyiso. Inkqubo cipande ingxenye biomicroscopy ikuvumela ukuba ufunde imeko lens kanye kwindawo ephambi umzimba vitreous. Kwakhona, ugqirha wasikhangela iinyembezi umboniso, kungqameko iinkophe kunye ngeenkophe. Le nkqubo ithatha malunga 10 imizuzu. Ngokuqhelekileyo eli xesha kwanele ukufumanisa isifo.

loviwo ultrasound

Ukusetyenziswa ultrasound njengesixhobo zokuxilonga izifo zamehlo mihla isekelwe phezu iimpawu namaza cuke. Wave, engena inyama elithambileyo iliso, ukutshintsha imilo yayo kuxhomekeka kubume lwangaphakathi esweni. Ngokususela kwidatha kunikezo kwamaza cuke kwi iliso, ugqirha wamehlo onokugweba isakhiwo sayo. Yeso ubunjwe macandelo ukuba isakhiwo eyahlukileyo ngokwalo ive. Xa wave cuke hits umda phakathi kwiindawo ezimbini, kukho inkqubo bokucingisisa kwaye refraction. Ngokusekelwe data malunga vangama zamehlo iqukumbela utshintsho zophendlo lwezifo kubume lweliso lakho.

Ubungqina obubonakalayo buxela ukuba ultrasound

Study eye ultrasound - tech indlela diagnostic zongeza iindlela ezivunywa uzingela ezimbi lweliso lakho. Sonography ngokuqhelekileyo ilandela iindlela wezinto uviwo malunga nesigulane eso. Kwimeko kukrokrelwa umzimba angaphandle kweli iliso, isigulane kuqala kuboniswa ray; kwaye kukho ithumba - transillumination.

Ultrasound lokufunyaniswa lweliso lakho kwezi meko zilandelayo:

• ngokuba ukufunda kwigumbi engile Icipande iliso, ingakumbi ukuma kwayo kunye nezakhiwo;
• ukufunda ngemeko lens intraocular ;
• ngokuba retrobulbar inyama umlinganiselo iimviwo ze-luvo optic;
• ngethuba loviwo umzimba ciliary. Study of iliso (olujikeleza kunye elibanjiswe) kwiimeko ngenkankulu ngexesha ophthalmoscopy;
• ekugqibeni ezihanjiswa amaqumrhu amazwe yeso; nokuhlola iqondo elalana kunye nokuhamba; ukufumana idata kwi iimpawu kazibuthe umzimba amazwe.

Ultrasound biomicroscopy iso

Nokufika ophezulu-ngqo izixhobo digital bakwazi ukufikelela processing ophezulu umgangatho iziganeko echo efunyenwe ngexesha amehlo biomicroscopy. Ukuphucuka eziphunyelelweyo ukusetyenziswa software yobungcali. Kwinkqubo zamehlo ezizodwa bakwazi ukuhlalutya iinkcukacha efunyenwe kwinkqubo survey, kwabe emva kwazo. Indlela ultrasound biomicroscopy unetyala inkangeleko yayo kwitheknoloji yedijithali, ekubeni isekelwe kucazululo yolwazi evela piezo elementi uphenyo lwedijithali. Kuba phando boluvo zisetyenziswa kunye rhoqo 50 MHz.

Iindlela lokuhlolwa abaphucuke

Xa ultrasound kusetyenziswa pin kunye emanzini iindlela.

indlela Iinkcukacha kulula ngakumbi. Kule ndlela, kwipleyiti probe wadibana kumphezulu iliso. Nomonde ukwenza instillation le ndindisholo kwi lweliso lakho, uze emva koko ibekwe esihlalweni. Enye zamehlo isandla elilawula uphenyo, eqhuba uphando, kwaye iiseti wesibini sixhobo. Xa indima yokuba kufuphi nokuhlangana medium ningazikrazuli izenzo fluid kolu hlobo saveyi.

indlela ukuntywiliselwa kubandakanya ukubeka biomicroscopy iliso phakathi uphenyo kunye umaleko inwebu phezu ulwelo okhethekileyo. Xa iliso isigulane ibekwe umlomo ezizodwa, leyo ihambisa woluvo probe. Ukubulawa ngexesha indlela ukuntywiliselwa ayisetyenziselwanga.
