Iyini futhi kanjani ukunquma ukucindezeleka kweso? Umkhuba wokucindezeleka kweso.

Iketshezi elisegumbini elingaphakathi, ekamelweni elingemuva, nasemzimbeni we-vitreous we-eyeball, linengcindezi ethile ezindongeni zeso. Ngenxa yokuthi ama-chambers omabili awawona amasongo angenalutho, axoxisana omunye nomunye ngokusebenzisa i-pupillary, futhi kusukela emzimbeni we-vitreous ikamelo elingaphansi lihlukaniswa kuphela yi-zinn ligament eguquguqukayo kakhulu. Ngakho-ke, uma ingcindezi kulezi zintathu zihlukile, khona-ke lo mthelela ulingana ngokushesha. Konke lokhu kusivumela ukuba sicabange iso njengelinye elilodwa eligcwele i-intraocular fluid. Ukucindezela ukuthi lokhu ketshezi okwenziwe ezindongeni zeso kubizwa ngokuthi i-intraocular, noma iso leso, i.e. I-ophthalmotonus yayo.

Ukucindezeleka kwamehlo , okujwayelekile okuhloswe ngawo isilinganiso esiphakathi komthamo we- eyeball kanye nenani lokuqukethwe kwalo, kungahlukahluka phakathi nenkathi yosuku, futhi lokhu ngeke kube ukugula. Ukucindezelwa kwegazi kunomthelela omkhulu emvelaphi yenani elifana nokucindezeleka kweso . Umkhuba wethoni yokuguqula ingu-120/80 mm Hg. Art. Lokhu kungenxa yokujwayelekile kwezitsha ezondla iso. Kodwa-ke, ukufana okuphelele phakathi kokucindezela komzimba kanye ne-ophthalmotonus ngomqondo wokuthi ngaphezulu kwezinga lokuqala, ngaphezulu kwesibili, cha. Ukucindezeleka kweso, okuyinto evame ukuhluka phakathi kuka-18 no-24 mm Hg. Art., Ngokukhululekile ngokuzimela. Lokhu kungenxa yokuthi ingcindezi yegazi yendawo ezingxenyeni zilawulwa ngokuzimela futhi hhayi njalo efana nezikebhe ezinkulu. Eyesweni, inkambo eyingozi kakhulu yezikebhe ezihamba phambili kanye ne-caliber yabo encane kakhulu ithambisa ukucindezela kwegagasi. Ngakolunye uhlangothi, inamba encane yezinkukhu ezinkulu ezinomsoco yenza kube lula ukuphuma kwegazi esweni, ukuvimbela ukwakheka kokungqubuzana kwe-venous kule sakhiwo. Kunesinye isici esinciphisa kakhulu ukucindezelwa kwengcindezi yegazi esweni. Lokhu kungukucindezela osmotic wezingxenye zeprotheyini zegazi.

Njengoba kuphawuliwe ngenhla, kukhona ukuguquguquka kwe-diurnal okunomshini wokucindezela iso, umkhuba wobubanzi obunjalo obungadlula u-3-5 mm Hg. Art. Noma yini ehamba ngaphesheya kwalolu bubanzi ichazwa njengokucindezela kweso eliphansi noma eliphakeme. Futhi lokhu kuyimvelo yokugula. Ushintsho lokuqala lubizwa nge-hypotension noma hypotension, kanti lesibili kuthiwa yi-hypertension, i-glaucoma. Ukuncipha kweso kungathathwa cishe, ngosizo lokucwaninga ngomunwe, kanye nosizo lwezinsimbi ezikhethekile, ikakhulukazi i- tonometer yeMaklakov. Uma ulinganisa ukucindezelwa kwe-intraocular nge-tonometer ye-iso, iso kumele kuqala li-anesthetized, kusukela Insimbi izobekwa ngqo kwi-cornea, okuyinto engxenyeni ebucayi kakhulu yembuthano yombono, kodwa yonke inyama yonke. Ukuze uthembeke, amasampuli amaningana athathwa kwelinye iso. Ukuze isibonakaliso sibe mthunzi, sebenzisa ama-dyes akhethekile ngokusekelwe ezinkingeni zesiliva (collargol) noma ezinye izinto. Ukulungisa idatha, ukubonakala kwendawo eshiywe yi-cornea yeso kusetshenziswe ephepheni, ngaphambilini kukhishwa ngoboya bekotini obugcwele utshwala. Isithombe kufanele sivunyelwe ukuba some kahle ukuze singagcini. Khona-ke izinga lokucindezelwa kwe-intraocular lithathwa ababusi abakhethekile. Indawo encane yokudlala, i-ophthalmotonus iphakeme, futhi, ngokuphambene, i-width indawo yokuphrinta, iyanciphise ukucindezeleka kweso. Esikhathini samanje, kunezindlela ezilula kakhulu zokunquma i-ophthalmotonus, ngokwesibonelo, i-tonometry engaxhunyiwe. Noma kunjalo, indlela yokuxhumana isasebenza kakhulu futhi, okubaluleke kakhulu, indlela ephumelelayo yokulinganisa ukucindezeleka kweso.

Uma amazinga aphezulu okucindezelwa kweso atholakala, kuhlolwa okuningiliziwe, kuhlanganise nokuqapha kwansuku zonke. Uma i-ophthalmotonus ephakanyisiwe noma eyanda ihlale ishintshiwe, i-glaucoma iyatholakala. Kungabangela ukulahlekelwa kancane kancane kombono. Ukuze ugweme ubumpumputhe obuphelele, ukucindezeleka kweso lesiguli (njengoba isazi singanquma ukuthi singayiphatha kanjani) kudinga ukusabela okusheshayo nokwanele, ukuhlushwa nokubekezela.
