Ingcindezi Intraocular - Izinga

Ukuze wenze kubukeke kangcono ingcindezi intraocular (IOP), cabanga ibhaluni. ezakheke alondolozwa umfutho womoya ngaphakathi kwalo. Mayelana efanayo ngenxa ingcindezi zangaphakathi ezivukayo ngenxa izinqubo kwamakhemikhali okwenzeka uzimisele futhi ukuma kabi noma isiphi isitho emzimbeni womuntu. It kuncike futhi ukugcwaliseka imisebenzi. Ngenxa nesenzakalo ngesikhathi esisodwa izinqubo ezimbili okuphambene - a inflow njalo futhi outflow ka uketshezi ngaphakathi inhlamvu yeso - futhi okwenyanga ingcindezi intraocular. IOP Jwayelekile luphakathi 16-24 mm HG. Art. Kuyingozi ngoba iso njengenhlangano anda eside (glaucoma) futhi yehlise eside (hypotension) ingcindezi intraocular.

Iziphi izizathu kungaholela izithelo zawo? Uma uketshezi ngaphakathi inhlamvu yeso ikhishwe obuningi, noma uma ephazanyiswa flow yayo, umphumela uba ukwanda ingcindezi intraocular. izici ngamunye yokwakheka isakhiwo kanye nezifo ze-uhlelo senhliziyo nemithambo yegazi iso futhi kungase kuphakame ushintsho IOP.

Uma ingcindezi intraocular luyanda ngokuhamba kwesikhathi, siyabhubha izinqubo umzimba ngaphakathi iso, wabulala amaseli we emsipheni optic futhi amaseli ngwengwzi. Konke lokhu angaliboni umuntu, ngoba kusukela ezindaweni neuropathy. Kancane kancane unciphise emkhakheni buka, futhi umphumela kungaba ubumpumputhe ephelele. Ngakho-ke kubalulekile ukwazi izimpawu uma zivela, kufanele ubone onguchwepheshe, futhi ukukala ingcindezi intraocular. Norma can eqiwe, uma amehlo akhathala ngokushesha uma njalo bazizwa ukusinda kuyo, uma uvame ngiphethwe yikhanda. Akubalulekile ukumchazela lokhu ukukhathala evamile, ingozi izinhlungu zokugula okungathí sina sikhulu kakhulu. Ngemva iminyaka engamashumi amane luhlolo ngu kudokotela wezifo zamehlo, kuhlanganise nesilinganiso IOP, ezibukwayo ensimini test futhi isimo emsipheni optic, kutuswa ngonyaka.

Indlela ukukala ingcindezi intraocular?

Kwesinye isikhathi abantu silahle evakashele udokotela wamehlo ngoba besaba IOP inqubo ukulinganiswa. Mhlawumbe lokhu kungenxa yokuthi indlela evamile yokulinganisa ingcindezi intraocular akuyona ngempela kumnandi kakhulu. Iso bemba izidakamizwa analgesic ewela Sinker iso ebusweni, ngaleso sikhathi udokotela ngeke kutholakale izinga IOP ngoba corneal degree kuka. Le ndlela nzima, kudinga magciwane ngokuphelele Sinker ukuvimbela ukutheleleka nesineke futhi akuzona olunembile kakhulu. Indlela yokuxhumana tonometry bancishwa emizweni ezingemnandi (nesineke azizwa okuncane kuphela emoyeni ukunyakaza) iphinde ivimbele ukutheleleka.

Ukuze wehlise IOP Udokotela angase anikeze isiguli amathonsi. Inqubo ukwelashwa lide futhi, naphezu alula okwakubonakala kuwukuphikisana, kudinga liqashelwe. Okokuqala, ukuze ungalahlekelwa nesenzakalo amathuba okuba nemiphumela engemihle, futhi okwesibili, ngesikhathi esifanele iso ingasetshenziswa dropwise. Kulezi zimo, udokotela kuzoshintsha lwemithi yokwelapha. Ngaphezu kwalokho, kungase kwenzeke ukuba ngingehlelwa nangeyodwa kulezi amathonsi ngeke babe ukuthonywa ngokungafanele ku ingcindezi intraocular, ilinganise Awukwazi ukuthola isikhathi eside. Kulokhu, ukuhlinzwa wenziwa (laser noma microsurgery) ukwakha izindlela ezintsha outflow uketshezi kusukela iso.

Khumbula ukuthi nakuba glaucoma ongakwazi ukulinganisela umthwalo ezibukwayo, kunezinye Izimo. Ngokwesibonelo, akunakwenzeka ukuba baphuze ketshezi isikhathi esingaphezu 2 amalitha ngosuku, nokuphakamisa izinsimbi, futhi isikhundla esiphendula esibhekisa phansi.

Kwehliswe ingcindezi intraocular lingaphansi ezivamile kuka okusezingeni eliphezulu, futhi ngokuvamile akuyona isifo ezimele. Ngokuvamile yenzeka ngemuva ukuvuvukala futhi yokulimala kwamehlo. Nokho, akusona kancane kuyingozi. Ngenxa wehlise IOP iphula iso umsoco, futhi lokhu kugcina kubangele ukufa ijwabu.

Ingozi njengoba iyokhushulwa futhi kwehlisa ingcindezi intraocular isikhathi eside. Norm, sikhumbula, ungaphakathi uhla kusuka 16 kuya 24 mm HG. Art. Wenzani uma uzithola izimpawu ingcindezi intraocular (eliphezulu kakhulu noma eliphansi)? Yiqiniso, ngokushesha kudokotela uyofuna icebiso, kudokotela wamehlo okunethiwethi.
