Xa wakha waya kuhlolwa iliso, ngaba ugqirha wafaka into ethile elisweni lakho njengomoya? Okanye bafaka inaliti encinci elisweni lakho bayijonga? Abantu abaninzi bacinga ukuba olu luvavanyo nje lokujonga ukuba yintoni na. Kodwa into elinganiswayo luxinzelelo olungaphakathi kweliso lakho. Namhlanje, masithethe ngokuba yintoni na olu xinzelelo lwamehlo, okanye into ebizwa ngokuba yi -Intraocular Pressure (IOP) ngokwezonyango.
Yintoni kanye kanye uxinzelelo lwangaphakathi kweso?
Ngamafutshane, oku kubhekisa kuxinzelelo lolwelo olungaphakathi kweliso lakho. Cinga ngeliso lethu njengebhola encinci ezele ngamanzi. Ukuze loo bhola ihlale imile kakuhle, kufuneka kubekho uxinzelelo ngaphakathi. Yiyo loo nto olu xinzelelo lubaluleke kakhulu kwimpilo yamehlo ethu kunye nokubona kwethu.
Kukho iintlobo ezimbini eziphambili zolwelo ngaphakathi kwamehlo ethu.
- Ihlaya Elimanzi: Olu lulwelo olufana namanzi olufumaneka kwinxalenye engaphambili yeliso (phakathi kwe-sclera kunye nelensi).
- I-Vitreous Humor: Le yinto etyebileyo, efana nejeli ekwigumbi elikhulu ngasemva kweliso.
Umzimba wethu ulawula uxinzelelo emehlweni ethu ngendlela emangalisayo. Njengoko kuveliswa i-aqueous humor entsha ngaphakathi kweliso, inani elilinganayo lolwelo oludala likhutshwa elisweni. Olu lwelo lukhutshwa ngenkqubo yokukhupha amanzi entle kakhulu elisweni. Oku sikubiza ngokuba yi-drainage angle. Le nkqubo ifana nokuvula itephu kunye nokuvula i-drain kwisinki. Amanzi ayangena aze aphume, ngoko ke isinki ayizalisi kwaye ayiphumi. Kodwa xa le balance ilahlekile, iingxaki ziyaqala.
Xa uxinzelelo olukwiliso lunyuka ngaphezu kwenqanaba eliqhelekileyo, silubiza ngokuba yi -Ocular Hypertension . Ukuba oku akunyangelwanga, kungonakalisa iindawo ezibuthathaka ngaphakathi kweliso, ingakumbi i-optic nerve ethwala umbono wethu ukuya engqondweni. Lo monakalo kwi-optic nerve unokukhokelela kwimeko ebizwa ngokuba yiGlaucoma , enokubangela ukulahleka kombono okungapheliyo ukuba ayinyangwa.
Kutheni uxinzelelo lwamehlo lusanda?
Nangona imizimba yethu idla ngokulawula olu xinzelelo, ngamanye amaxesha olu lungelelwano lunokuphazamiseka. Nazi izizathu eziphambili zokuba kutheni.
| Unobangela | Kalula nje... |
|---|---|
| Ukuveliswa ngokugqithisileyo kwe-aqueous humor | Ulwelo oluninzi kakhulu luqokelelana ngaphakathi kweliso. Emva koko, ulwelo oluninzi luqokelelana ngaphakathi kunelo luphumayo. |
| Ukuvaleka kwe-engile yokukhupha amanzi | Umjelo wokukhupha amanzi oqokelelana uyavaleka, nto leyo enyusa uxinzelelo ngaphakathi kweliso. |
| Ukulimala Kwamehlo/Ukwenzakala Kwamehlo | Xa into ibetha okanye yenzakalisa iliso, le nkqubo ibuthathaka ngaphakathi inokuphazamiseka. |
| Amanye amayeza | Le meko inokubangelwa ngamayeza, ingakumbi ii-corticosteroids (amathontsi amehlo, iipilisi, amafutha okugcoba). Ngoko ke, musa ukuzisebenzisa ezi zinto ngaphandle kwengcebiso kagqirha. |
Uxinzelelo lwamehlo lulinganiswa njani?
Olu vavanyo loxinzelelo lubizwa ngokuba yi-tonometry . Ingcali yakho yokhathalelo lwamehlo iya kwenza oku ngexesha lovavanyo lwamehlo. Lulinganiswa ngeemilimitha ze-mercury (mmHg). Le yiyunithi efanayo apho uxinzelelo lwegazi lwakho lulinganiswa khona.
Uxinzelelo oluqhelekileyo kwiliso eliphilileyo luphakathi kwe-10 mmHg kunye ne-20 mmHg .
Olu vavanyo ludla ngokwenziwa ngeendlela ezimbini:
1. I-Air Puff Tonometry: Oku kubandakanya umatshini ovuthela umjelo womoya omncinci elisweni lakho. Uxinzelelo lulinganiswa ngokulinganisa ukuba inxalenye ecacileyo engaphambili yeliso (i-cornea) ityhala kangakanani kumjelo womoya.
2. I-Contact Tonometry: Ngale ndlela, ugqirha ubeka amathontsi abangela ukuba amehlo akho angaboni kakuhle aze achukumise kancinci isixhobo esincinci kakhulu kumphezulu weliso lakho ukuze alinganise uxinzelelo.
Kuvakala njani xa uxinzelelo lwamehlo lusanda?
Le yeyona nto iyingozi kakhulu ngesi sifo kwaye yinto ekufuneka siyiqwalasele.
Uninzi lwexesha, uxinzelelo oluphezulu lwamehlo alubangeli zimpawu. Indlela ekuphela kwayo yokwazi ukuba unalo kukuhlolwa kwamehlo. Iimpawu zihlala ziqala ukubonakala emva kokuba umthambo wokubona wonakele kwaye umbono wakho uchaphazelekile. Ngelo xesha, omnye umonakalo sele wenziwe.
Kungoko ke kubaluleke kakhulu ukuba uhlolwe amehlo rhoqo, ingakumbi emva kweminyaka engama-40, nokuba akukho ntlungu.
Ufanele uye nini kugqirha?
Nangona uxinzelelo lwamehlo oluphezulu ludla ngokungabangeli zimpawu, iimpawu ezithile zinokuvela kwiimeko ezithile ezingxamisekileyo okanye njengoko i-glaucoma iqhubeka.
| Ixesha lokufuna ingcebiso kwezonyango | |
|---|---|
| Ukuba unale mpawu, bonana nogqirha ngokukhawuleza: | |

| Yiya kwiSebe leeNgxamiseko (i-ETU) ngoko nangoko ukuba ezi zinto zenzeka: | |

Ngaba uxinzelelo lwegazi luyinto enye, uxinzelelo lwamehlo luyinto enye, okanye zimbini izinto?
Ewe. Eli lithuba apho abantu abaninzi badideka khona. Uxinzelelo lwegazi oluphezulu (uxinzelelo lwegazi oluphezulu) kunye noxinzelelo lwamehlo oluphezulu (uxinzelelo lwegazi oluphezulu) ziimeko ezimbini ezahlukeneyo. Ukuba unoxinzelelo lwegazi oluphezulu akuthethi ukuba uxinzelelo lwamehlo luphezulu. Enye ayibangeli enye ngokuthe ngqo.
Kodwa, khumbula oku: Abantu abanoxinzelelo lwegazi oluphezulu basengozini enkulu yokufumana i-glaucoma. Kwakhona, ukuba uxinzelelo lwegazi luphezulu kakhulu okanye luphantsi kakhulu, ukuhanjiswa kwegazi kwi-optic nerve kunokuchaphazeleka, okubangela ukulahleka kokubona. Ngoko ke, ukuba unoxinzelelo lwegazi oluphezulu, kubalulekile ukuthetha nogqirha wakho, uqaphele umngcipheko wakho we-glaucoma, kwaye ufumane uvavanyo lwamehlo rhoqo.
Ugqirha wakho unokukunika amaconsi emehlweni, unyango lwelaser, okanye notyando njengonyango. Oku kuya kuqinisekiswa ngokuhlola izinto ezininzi, kuquka uxinzelelo lwamehlo akho kunye nemeko yemithambo-luvo yakho.
Umyalezo Wokuya Ekhaya
- Uxinzelelo lwe-intraocular (IOP) lubalulekile kwimpilo yamehlo ethu, kodwa kufuneka luhlale lukwinqanaba elithile (10-20 mmHg).
- Ekubeni uxinzelelo lwamehlo oluphezulu (uxinzelelo lwamehlo oluphezulu) ludla ngokungabonisi zimpawu, kubaluleke kakhulu ukuba uhlolwe amehlo rhoqo.
- Ukuba le meko ayilawulwa, inokukhokelela kwi-glaucoma, enokubangela ukulahleka kombono okungapheliyo.
- Ukuba uneminyaka engaphezu kwama-40 ubudala, unembali yentsapho yakho ye-glaucoma, okanye uneemeko ezifana nesifo seswekile okanye uxinzelelo lwegazi oluphezulu, qiniseka ukuba uhlola amehlo akho ubuncinane kanye ngonyaka.
- Landela imiyalelo kagqirha wakho ngokuchanekileyo. Kubaluleke kakhulu ukusebenzisa amathontsi amehlo ngexesha elifanelekileyo nangedosi efanelekileyo.
👩🏽⚕️ Imibuzo eyongezelelweyo (Ii-FAQ)
💬 Inaliti/iipilisi zeprocainamide liyeza elinamandla kakhulu elinikwa isifo esinjani?
Eli asiloyeza liqhelekileyo! Eli liyeza elinamandla kakhulu elisetyenziswa ezibhedlele ukusindisa ubomi kwiimeko ezinzima ze-'Antiarrhythmic - Class 1A', ingakumbi xa amagumbi asezantsi entliziyo ebetha ngequbuliso ngokungalawulekiyo kwaye isigulana siza kufa (ii-Ventricular Arrhythmias ezisongela ubomi / i-V-Tach)!
💬 Xa intliziyo ibetha kakhulu, ungayilungisa njani indlela intliziyo ebetha ngayo ngokunika eli yeza (iProcainamide)?
Intliziyo ibetha ngokukhawuleza ngenxa yombane (Action Potentials)! Kwisigqi sokuqala, kufuneka amasuntswana 'eSodium' angene ukuze atshaje iiseli. Xa le pilisi ingena entliziyweni, ivala kwaye itshixe zonke iingcango ezivumela i-sodium ukuba ingene. Ukongeza, yandisa ixesha elithathwayo ukuze iiseli zitshaje kwaye ziphinde ziqalise ukusebenza (ngokuvimba i-potassium nge-metabolite ye-NAPA)! Oku kuthintela intliziyo ekubetheni ngokukhawuleza kwaye kunciphise isigqi.
💬 Zeziphi 'iingozi ezibulalayo (Isilumkiso seBlack Box / Lupus)' ekufuneka abantu abasebenzisa eli yeza (Procainamide) bazi ngazo?
Eyona ngozi inkulu kukuba inokubangela 'isigqi sentliziyo esitsha nesibulalayo (iProarrhythmia)' (yiyo loo nto inikwa kuphela ngexesha likaxakeka)! Enye ingozi enkulu nephazamisayo kukuba emva kokusebenzisa oku iinyanga ezimbalwa, ngaphezulu kwama-30% ezigulana ngokuqinisekileyo ziya kuba nesifo esibi esibizwa ngokuba yi-'Lupus-like Syndrome' (ububomvu bobuso obufana nebhabhathane, iintlungu zamalungu)! Kukwakho nomngcipheko omkhulu wokufa ngenxa yokutshatyalaliswa ngokupheleleyo kweeseli ezimhlophe zegazi (i-Agranulocytosis).
