Izindlela amehlo biomicroscopy

Biomicroscopy esweni - indlela yesimanje lekutfola ucwaningo owenziwa usebenzisa idivayisi ekhethekile - isibani umqhewu. Isibani Special siqukethe umthombo wokukhanya, okungase ukushintsha ukugqama, futhi ngesibonakhulu stereoscopic. Ukusebenzisa indlela yokuqhuba isifundo of biomicroscopy ka anterior ingxenye iso.

ubufakazi

Le ndlela isetshenziswa ngesikhathi esifanayo ne kudokotela wezifo zamehlo ejwayelekile umbono ukuhlolwa kanye ukuxilongwa fundus. Biomicroscopy ziyasebenza uma umuntu esola khona sihlahla esweni. Ngeziphambeko lapho udokotela ekunika inhlolovo zihlanganisa: conjunctivitis, ukuvuvukala, imizimba angaphandle iso, izimila, keratitis, uveitis, dystrophies, opacities, lolu ngwengwezi nezinye. Biomicroscopy ilihlo wabonisa luhlolo ukwelashwa ngaphambi nangemuva kuhlinzwa esweni. Futhi, inqubo esiyakuqokwa njengoba okungeziwe izifo kohlelo endocrine.

inqubo kanjani?

Inqubo iso biomicroscopy abezindaba akakubangeli ubuhlungu esigulini. Umuntu uyaphawula kuphela wokukhanya begodu enze udokotela isicelo. Inqubo Akudingi ukuqeqeshwa okukhethekile futhi kuyashesha. Biomicroscopy wenziwa egumbini mnyama. Udokotela wamehlo uyaqikelela ukuthi umuntu uye wathatha isikhundla kwesokudla: kwesilevu ivuliwe ukwesekwa okukhethekile ikhanda futhi encike ebunzini lakhe nge indawo kubha. Uma isiguli libekwe kahle ekhanda isinyathelo, kudokotela wamehlo okunethiwethi iqala ukufunda inqubo. Udokotela kushintsha isiqondiso futhi ukukhanya ugongolo ukukhanya, kuyilapho sigcina ijwabu ususwe ukushintshwa okukhanyisa. Inqubo anterior ingxenye biomicroscopy ikuvumela ukuba ufunde mayelana nesimo se-lens kanye phambi indawo emzimbeni Vitreous. Futhi, udokotela ehlola ifilimu izinyembezi, imiphetho Isivalo kanye eyelashes. Inqubo ihlala cishe imizuzu engu-10. Ngokuvamile ngalesi sikhathi kwanele ukuxilonga izifo.

ultrasound luhlolo

Ukusetshenziswa ultrasound njengoba ithuluzi zokuxilonga zamehlo yesimanje kusekelwe izakhiwo amagagasi ultrasonic. Wave, ekujuleni izicubu zomzimba ezithambile esweni, ukushintsha ezakheke kuncike Sakhiwo sangekhatsi iso. Ngokusekelwe idatha ukusatshalaliswa amagagasi ultrasonic iso, udokotela wamehlo onganquma okufanele ukwenze oyiyo. I inhlamvu yeso yakhiwa izingxenye kokuba isakhiwo ezahlukene ngokuya acoustic. Lapho i wave ultrasonic hits umngcele phakathi izindawo ezimbili, kukhona inqubo reflection kwalungiswa izinkunga zokubona. Ngesisekelo idatha emayelana kuveza ophthalmologist kuphetha izinguquko sokugembula kule nokwakheka yeso.

Izimpawu ze-ultrasound

Isifundo iso ultrasound - tech indlela zokuxilonga okuyinto sigcwalisa izindlela classical uzingela pathologies we inhlamvu yeso. Sonography ngokuvamile ilandela izindlela zasendulo ukuhlola isiguli. Endabeni esolwa umzimba angaphandle iso, isiguli kuqala kuboniswe esimweni; naphambi kuwuphawu lwesimila - transillumination.

Ultrasound sitholakele yeso kulezi zimo ezilandelayo:

• sokutadisha anterior ekamelweni engela iso, ikakhulukazi nesimo sendawo yayo nezakhiwo;
• ukufunda ku isimo lens intraocular ;
• I-retrobulbar izicubu nesilinganiso nokuhlola emsipheni optic;
• ngesikhathi luhlolo yomzimba ciliary. Isifundo esweni (semithambo kanye yokumboza) ezimweni kanzima ngesikhathi ophthalmoscopy;
• ekunqumeni okubekwayo zemizimba angaphandle yeso; ekuhloleni degree of Ukungena futhi ukuhamba; ukuthola idatha izakhiwo magnetic nomzimba angaphandle.

Ultrasound biomicroscopy esweni

Njengoba sekunama-ephezulu ukucacisa imishini digital uyakwazi ukufeza eliphezulu ngokucubungula amasignali echo wathola phakathi kwamehlo biomicroscopy. Ubungcono siyithola ngokusebenzisa isofthiwe professional. Ngo uhlelo ophthalmologist ekhethekile uyakwazi ukuhlaziya ulwazi olutholakele inqubo inhlolovo, futhi ngemva kwaso. Indlela ultrasound biomicroscopy ukweleta ukubukeka kwayo ukuze ezobuchwepheshe, ngoba zisuselwa ekuhlaziyweni kolwazi kusukela isici Piezo we probe digital. Ukuze ucwaningo izinzwa asetshenziswa nge imvamisa 50 MHz.

Izindlela ukuhlolwa ultrasonic

Lapho ultrasound isetshenziswa pin nokucwiliswa izindlela.

Imininingwane indlela Ngaphezu elula. Kule ndlela, ipuleti Uphenyo nabo ebusweni iso. Sibekezele ukwenza instillation we izinzwa phezu inhlamvu yeso, bese ibekwe esihlalweni. Omunye isandla ophthalmologist elawula uphenyo, ucwaningo izifundo, kanye amasethi lisebenze yesibili. Ekhuluma ewukuhlakanipha okwenziwe konemimoya elihlangana likhiphe izenzo uketshezi kulolu hlobo inhlolovo.

Babecwiliswa iso biomicroscopy indlela kuhilela ukubeka phakathi probe futhi ungqimba cornea ebusweni uketshezi ekhethekile. Esikhathini iso isiguli isethwe umlomo wombhobho ekhethekile, esishukumisela inzwa uphenyo. Anesthesia ngesikhathi indlela ukucwiliswa alisetshenziswa.
