Ntoni na nendlela ukujonga uxinzelelo kwi iliso? UNorma xi amehlo.

Le engamanzi ise egumbini ngaphambili, egumbini ngasemva, kwakunye ngomzimba vitreous lweliso lakho, kukho uxinzelelo eludongeni iliso. Ngenxa yokuba zombini magumbi nemingxuma uninsulated, ethetha nabanye kwikroba lokuvula pupillary Igumbi abasemva ezahlulwe sisithuba kuphela inyanda bhetyebhetye kakhulu Zinn vitreous. Ngoko ke, ukuba uxinzelelo kwezi nemingxuma ezintathu ezahlukeneyo, umahluko ngokukhawuleza ezihambelana. Konke oku kubonisa umngxuma neso elilodwa ezaliswe ulwelo intraocular. Uxinzelelo apho ulwelo enalo eludongeni iliso, ebizwa intraocular okanye TENSO iliso, ngamanye ocular yakhe.

Ocular wegazi, izinga olumisela umlinganiselo phakathi amandla lweliso lakho kunye isixa imixholo zisenokwahluka ngandlel emini, kwaye ngeke ngezifo. uxinzelelo lwegazi kunempembelelo enkulu phezu imvelaphi wukulu ezifana ocular uxinzelelo. emithanjeni oqhelekileyo Ithoni imizuzu-80 120 / mmHg. Art. Oku kungenxa iimpahla eziqhelekileyo sikhule iliso. Noko ke, okukhona epheleleyo phakathi uxinzelelo lwegazi kunye ocular ngengqiqo ukuba liphakamile ixabiso lokuqala, i ephakamileyo kunye yesibini, akukho. uxinzelelo Eye, leyo iyahluka izinga-18 ukuya kuma-24 mm HG. v., ubukhulu becala ngokuzimeleyo. Oku kungenxa yokuba abantu basekuhlaleni uxinzelelo yegazi kwi amalungu self-ilawulwa kwaye akusoloko zifana ezityeni ezinkulu. Emehlweni kwekhosi jiko kakhulu ehamba neempahla, kunye nobukhulu yabo encinane kakhulu athambe lencinibakazi xi ukubetha. Kwelinye icala, kukho inani elincinane iziqu ezinkulu lwemithambo lula kakhulu yayikukuphuphuma igazi iliso, ziyibuyisela ukuyilwa kwalo isakhiwo stasis lwemithambo. Kukho nenye into leyo kunciphisa kakhulu yengcinezelo wegazi iliso, oko - uxinzelelo osmotic amaqhekeza protein igazi.

Njengoko sele kutshiwo ngentla apha, kukho ukwehla ngemihla lubandakanya lwegazi ocular, izinga loo awo oscillation akuthethi ngaphezulu 3-5 mm imizuzu HG. Art. Yonke into engaphaya lo umda kuchazwa koxinzelelo iliso ophantsi okanye phezulu. Le yimeko yezifo. Shintsho lokuqala ibizwa ngokuba hypotension okanye uxinzelelo lwegazi esezantsi, kwaye eyesibini - lwegazi, glaucoma. Tensa Alinako kumiselwa kalukhuni ngokuyincina digital, kwakunye ngoncedo bezixhobo ezizodwa, ezifana ibe tonometer of Maklakov. Xa intraocular uxinzelelo kumetwa tonometer ocular ngaphambili kufuneka anesthetize iliso, ekubeni isixhobo iya kufakwa ngqo kwi inwebu, nto leyo nxalenye vakalelo lomzimba ukujonga nje kuphela, kodwa yonke eziphilayo. Kuba ukuthembeka unaliso linye Ususe iisampulu ezimbalwa. Afune ndahamba ukusetyenziswa imibala ezikhethekileyo izisombululo zesilivere-based (isilivere colloid) okanye ezinye izinto. Kuba ilungisa yamanyala data site, kushiywe inwebu ye iliso, lisetyenziswa iphepha, ngaphambili wazisula kunye yomqhaphu desensitised notywala. Lo mfanekiso kufuneka bunikwe zome ngononophelo, ukuze bagcobe. Emva koko, umgca okhethekileyo kugqiba inqanaba xi intraocular. I ayemxinwa endle, kwangalo ophthalmotonus ngasentla, yaye, icala, yembutho yamanyala ngokubanzi, uxinzelelo iliso usezantsi. Ngelo langoku Okwangoku, kukho iindlela lula ngakumbi ukumisela uxinzelelo intraocular, umzekelo, non-contact tonometry. Nangona kunjalo, indlela contact sisabalulekile kakhulu yaye, okona kubaluleke kakhulu, indlela ephumelelayo ukulinganisa amehlo tensor.

Xa kwafunyanwa kumanqanaba aphezulu yengcinezelo eye, ukuqhuba uviwo oluneenkcukacha, equka esweni yabo yemihla ngemihla. Ukuba ngokusisigxina ophthalmotonus ephakamileyo ngoko bene glaucoma kunye. Oku kungakhokelela kwilahleko kancane umbono. Ukwenzela ukuphepha kubumfama iyonke, umguli a xi ophezulu iliso (ukuba inyangwa njani na ukufumanisa kuphela oyingcali) lifuna impendulo ekhawulezileyo kunye olwaneleyo iliso, ingqondo kunye nomonde.
