Ukugcina isimo sesimo saso, itoni yayo, i-metabolism in tiscu kunye ne-microcirculation echanekileyo inikeza uxinzelelo olunzulu lwe-intraocular - umgangatho oqhelekileyo kubantu abadala balolu hlobo (ophthalmotonus) kufuneka uhlale unqanaba elimisiweyo. Ubungakanani bayo bubekwe ngokuhambelana nomthamo wokungena kunye nokuphuma kwamanzi.
Uxinzelelo lwe-intraocular lufanele lwenze ntoni?
Okokuqala, kufuneka kuqatshelwe ukuba kukho i-ophthalmotonus yinyani kunye ne-tonometric.
Kwimeko yokuqala, ixabiso elichanekileyo loxinzelelo lwamehlo linokumiselwa kuphela yindlela enye: faka inaliti yesomometer ekamelweni langaphakathi lelihlo nge-cornea, yenza umlinganiselo othe ngqo. Le ndlela ayizange isetyenziswe kwinkqubo yekliniki ixesha elide.
I-ophthalmotonus ye-Tonometric imiselwe ngamacebo ahlukeneyo kunye nezixhobo:
- I-Tonometry ngokweMaklakov;
- i-tonometry engaqhagamshelwanga;
- I-tonometer yeGoldmann;
- Iimitha zeeonometers;
- Pascal tonometers.
Ngaphezu koko, i-ophthalmologist enamava inokulinganisela ukulinganisa inani lexinzelelo, ngokunyanzela iminwe kwiminwe yamehlo anezikhwebu ezivaliweyo.
Kukholelwa ukuba ixabiso eliqhelekileyo le-ophthalmotonus kufuneka libe li-10-21 mm Hg. Ubugcisa. Naluphina ukuphambuka kwimida ebonisiweyo yintlupheko kwaye ichaphazela kakubi i-homeostasis yamehlo.
Imigangatho yokunyanzeliswa kwe-intraocular nge minyaka
Imida emiselweyo yobukhulu obucatshangelwayo ifanelekileyo kubasetyhini banoma yiphi iminyaka. Kodwa utshintsho kwi-eyeball kunye nezicubu ezinama-corneal ezenzeka ngokuguga komzimba zichaphazela izibonakaliso ezicacisiweyo ze-ophthalmotonus.
Ngaloo ndlela, umda ophezulu wesigxina soxinzelelo lwe-intraocular emva kweminyaka engama-50-60 yanda kakhulu - ixabiso le-23 mm Hg livumelekile. Ubugcisa.
Izigulane ezi zilandelayo ziguqula i-ophthalmotonus:
- ubukho bomzimba wasemzini kweliso;
- uxinzelelo lwegazi oluphantsi okanye i-hypotension;
- ukungena entlungu;
- izifo ezikhuselekileyo kunye nezinye iimeko ezihambelana nokudambisa amanzi;
- izifo ezivuthayo zamehlo (irites, uveitis);
- isifo sikashukela esine-ketoacidosis, i-ketoacidotic coma;
- i-detinal detachment ;
- isifo esingasigxina sesibindi;
- iingxaki emva kokuhlinzwa;
- izifo zeengtso;
- ukuphuhliswa kweso
- ukunyamezela, uxinzelelo;
- isifo esiyingozi.
Iinguqu ezinokuthi zitshintshe kwi-eye pressure kwi-glaucoma, ngokukodwa kubasetyhini abangaphezu kweminyaka engama-40. Ngoko ke, i-ophthalmologists incomela ukutyelela ugqirha ngamnye unyaka ukulungiselela uviwo olukhuselekileyo oluqhelekileyo, oluvumela ukuhlolwa okubanzi kokusebenza kwamalungu ombono kunye nobukhulu be-ophthalmotonus.
Yintoni eqhelekileyo yoxinzelelo lwe-intraocular kwi-glaucoma?
Inkcazo echazweyo ixhomekeke ekumeni nasebunzima be- glaucoma . Ingqikithi kukho i-degrees ezi-4 zezi zifo zeso, ngasinye ngasinye esinamaxabiso aso ophthalmotonus:
- Okokuqala. Uxinzelelo lwe-intraocular kuthathwa njengesiqhelo kwaye aludluli kwi-26 mm Hg. Ubugcisa.
- Phuhliswa. I-Ophthalmotonus ngokukhawuleza iphakanyisiwe - 27-32 mm Hg. Ubugcisa.
- Kude emva. Uxinzelelo lwe-intraocular luyanda kakhulu, lugqitha kwi-33 mm Hg. Ubugcisa.
- Terminal. Ixabiso le-ophthalmotonus likhulu kunama-33 mm Hg. Ubugcisa.
Uxinzelelo lwe-intraocular kwi-glaucoma luyaphambukela kwimimiselo engaqhelekanga, kodwa ngokuthe ngcembe, njengoko eso sifo siyaqhubeka kwaye ukuchasana nokuphuma kwe-fluid kwiinkamelo zamehlo kwanda. Ngenxa yesi sizathu, isigulane asiva nangoko ukunyuka kwi-ophthalmotonus, eyenza ukuba i-glaucoma ixilwe ngokukhawuleza.
