Sample Schirmer: izinkomba, inqubo ukusebenza, imiphumela

indlela Test, okuzoxoxwa, ubizwa ngokuthi behlonipha kudokotela wezifo zamehlo, uklanyelwe - Otto Schirmer. Lokhu Assay inquma lizinga ethakwa uketshezi izinyembezi, degree of umswakama nokugcinwa ebusweni corneal.

Izinkomba kanye contraindications

ukuhlolwa Schirmer sika sisetshenziswa esolwa ngokuba:

• ukuvuvukala corneal we conjunctiva;
• syndrome ka "izinyembezi";
• Sjögren Syndrome (a okungamahlalakhona, ukulahlekelwa okuqhubekayo ezicutshini esithinta nezindlala ezikhiqiza uketshezi yangaphandle - ngamathe kwamangqamuzana);
• iziyaluyalu slezoobrazovaniya ngenxa kokuthola amalungiselelo wezokwelapha.

Zenzele syndrome ka "izinyembezi" kungase kube ngenxa yezizathu eziningana:

1. Ukuphelelwa amanzi emzimbeni.
2. nesineke Asebekhulile.
3. Conjunctivitis noma ezinye izifo iso.
4. Vitamin A ukuntula (yokuntuleka uvithamini A).
5. Iva iso.
6. inkinga postoperative noma unomphela ngemva laser umbono ukulungiswa.
7. Lokho okubizwa ngokuthi i syndrome yesibili, esizibonakalisa rheumatoid arthritis, wegazi, lymphoma.

ukuhlolwa Schirmer sika is contraindicated ku:

• perforations (reshaping) we uthinta inhlamvu yeso;
• fistula;
• isilonda corneal ekuthuthukiseni ungqimba;
• isikali Ukuwohloka corneum stratum.

Izindlela ukuhlolwa

emapheshana yokuhlola isampula Schirmer - a ehlungiwe esayizini ekhethekile iphepha: 5 mm ububanzi 35 mm ubude. Ukuhlehlela Emuva 5 mm ukusuka strip onqenqemeni wabonisa, ophthalmologist uphendulela engela yayo 45 degrees, futhi kwehlisa ukuba ijwabu leso engezansi isiguli, ukugxila engxenyeni phakathi yangaphandle futhi phakathi ingxenye. Kubalulekile phakathi naleyo nqubo akusho ubuhlungu cornea.

Ngokusho kweminye izindlela isiguli ngesikhathi inqubo ukuvala amehlo, ngakolunye - ukuba ame isibindi futhi kancane phezulu. Ukukhanyisa egumbini kufanele kube ukhululekile - awazona hhayi elikhanyayo kakhulu.

Schirmer ukuhlolwa kuthatha cishe imizuzu emihlanu. Phakathi nalesi sikhathi, emapheshana iphepha amunca izinyembezi ifilimu prekornealnuyu futhi umswakama echibini lacrimal.

Izinhlobo amasu test

Sample Schirmer olwenziwa ngezindlela ezimbili:

1. With ukusetshenziswa izinzwa wendawo. angakwazi izinzwa sinezela basal ukukhululwa reflex likhiphe fluid ukushukuma ephepheni. Ngemva instillation of izinzwa wendawo fornix engezansi conjunctiva omisiwe ukulahla izidakamizwa ngokweqile ungafakiwe uketshezi lacrimal, ngaleyo ndlela kwande umthamo yayo.
2. Ngaphandle ukusetshenziswa ejenti imithi ebulala izinzwa. ukuhlolwa okunjalo bamehlo elilandelayo kubhekwe esinembile ngoba iqeda kuhlangana izinyembezi kanye izidakamizwa iqondiswa, sibonisa kuphela yi athi 'okuhlanzekile'. Lolu hlobo lwe-isampula ungachazwa ekuxilongeni uphawu "izinyembezi".

Futhi ukuhlolwa Schirmer sika ihlukaniselwe I neyesi-II. Eyokuqala Kwenziwa besebenzisa emapheshana test ngokuthintana indlela wathi. Uhlobo lwesibili kusiza ukuhlola inani reflex (asabela ngayo ezintweni) uketshezi lacrimal. Wayeqhuba efanayo, kodwa kuvusa ukukhululwa ophthalmologist lacrimal uketshezi by inkanuko amavesi acinene tesifundvo nge swab ukotini.

YeSampuli Schirmer: kuyinsakavukela kanye nokusuka

Ezimweni ezimbi kakhulu, lesi sifo "iso ezomile" ukusebenza isivivinyo strip kungenzeka ezingeni ka zero. Kuyinsakavukela kuyinto Encane labantu nesineke izibalo ezidlula 15 mm. Uma amazinga aphansi - ke examinee uhlushwa uhlobo "izinyembezi" syndrome:

• 14-9 mm - okuncane ukushintshashintsha ukucindezelwa Kwabiwa lachrymal uketshezi;
• 8-4 mm - ezingeni isilinganiso ukuthuthukiswa yalesi sifo;
• esingaphansi 4 mm - amafomu okunzima sifo ukoma corneal.

ukusebenza kahle: ayi-10-30 mm. Uma iminyaka yobudala lesiguli iminyaka engaphezu kwengu-60, isibalo sabantu strip test angaphansi kuka-10 mm kuzofundwa sivamile kuye Nokho, bavame ukugxila akazange kufanele.

Sivamile isampula II, inquma Kwabiwa lemali reflex izinyembezi, hhayi ngaphansi kuka 15 mm. Obalulekile kokubili izinhlobo amasampula abhekwa umehluko imiphumela yokuhlola i-pair of amehlo ngaphezu kuka-27%.

Ukuhlolwa kwakamuva emuva kokwenziwa Schirmer:

• luhlolo umqhewu isibani;
• rose ibala bengal noma flyuores-inja;
• Ucwaningo yokuthola isikhathi izinyembezi isikhawu ifilimu ukudabuka.

Sample Schirmer - lula futhi fast, indlela ephumelelayo for ukuxilongwa sokuqala lesi sifo of "izinyembezi" futhi izinkulumo ezinjalo kuye, Izifo eziphatha ukwabiwa uketshezi lachrymal. Ukuhlolwa kusiza ophthalmologist ngokushesha kutholakale izinga ethakwa uketshezi izinyembezi (basal, reflex) nemathothali yabo isiguli ngaphansi luhlolo.
