Ngaba wakha wazibuza ukuba kungakanani okwenzekayo ngaphakathi kweli lungu lincinci elibizwa ngokuba liliso lethu, ukuba lisebenza nzima kangakanani? Iliso liyindalo emangalisayo ngokwenene. Namhlanje siza kuthetha ngenxalenye ebaluleke kakhulu yeliso esingathethi kakhulu ngayo. Leyo 'yigumbi elingaphambili' leliso, okanye ngokwezonyango , iGumbi elingaphambili . Nangona le yindawo encinci, yinxalenye ebalulekileyo ekuboneni kwakho.
Kalula nje, yintoni le gumbi lingaphambili?
Kulula kakhulu. Inxalenye ecacileyo, engqukuva engaphambili kweliso lakho ibizwa ngokuba yi-cornea . Isithuba esincinci esingasemva kwe-cornea sibizwa ngokuba yi-anterior chamber. Le chamber ayipheleli nje kuphela. Izaliswe lulwelo olukhethekileyo ngaphakathi. Silubiza olo lwelo ngokuba yi-aqueous humor .
Ngoku usenokuba ucinga, "Yintoni le ndawo incinci, kunye nolwelo olukuyo?" Oku kunendima ebaluleke kakhulu.
Khawuthelekelele uthatha ilensi ejijekileyo kwaye ukhulisa into ethile. Ukuze uyibone ngokucacileyo, kufuneka kubekho umgama othile phakathi kwento, ilensi, kunye neliso lakho. Yiyo loo nto amehlo ethu anjalo. Sidinga ukugcina umgama othile phakathi kwelinsi, i -retina, kunye ne-cornea engaphakathi kwamehlo ethu.
Igumbi elingaphambili libalulekile ekugcineni lo mgama. Ulwelo olungaphakathi kulo (Aqueous Humor) ludala uxinzelelo oluthile ngaphakathi kweliso. Olu xinzelelo silubiza ngokuba luxinzelelo lwangaphakathi kweliso. Njengokuba xa uvuthela umoya kwibhola, uyafutha uze ubuyele kwimo yawo efanelekileyo, kungenxa yolu xinzelelo ukuba iliso 'lifutha', oko kukuthi, linemilo efanelekileyo. Yingakho zonke iindawo zeliso zikwindawo ezifanelekileyo, kwaye sinokubona ngokucacileyo.
Olu lwelo (i-aqueous humor) luhamba njani ngaphakathi kweliso?
Le yinkqubo emangalisayo kakhulu. Ukuba yonke into isebenza kakuhle ngaphakathi kwamehlo ethu, olu lwelo (Aqueous Humor) luyaveliswa, lushukume, kwaye lususwe ngomlinganiselo ofunekayo. Oku kunika amehlo isondlo kunye neoksijini, kwaye kunceda nenkqubo yomzimba yokuzikhusela. Ukulinganisela kolu lwelo kubaluleke kakhulu. Ukuba ulwelo luyanda, uxinzelelo lwamehlo luyanda, kwaye ukuba luyancipha, uxinzelelo luyancipha. Akukho nanye kwezi ilungileyo emehlweni.
Nantsi indlela esebenza ngayo le nkqubo:
1. Olu hlobo lolwelo olumanzi luqala ngokuveliswa yinxalenye yeliso ebizwa ngokuba yiCiliary Body .
2. Olu lwelo luqokelelana 'kwigumbi elingasemva ' emva kwenxalenye enemibala yeliso, i-iris .
3. Ukusuka apho, iliso lidlula kumfundi lize lingene ' kwigumbi elingaphambili ' esithetha ngalo.
4. Emva kokuba igumbi elingaphambili lizaliswe, ulwelo olugqithisileyo kufuneka luphume. Oku kwenzeka ngenkqubo yokukhupha amanzi ekhethekileyo ekhoneni legumbi elingaphambili. Siyibiza ngokuba yiTrabecular Meshwork .
5. Ulwelo oludlula kule nkqubo yokukhupha amanzi ekugqibeleni luqokelelana kwimithambo yegazi kwinxalenye emhlophe yeliso (i-sclera) luze luxubane negazi.
Lo mjikelo uqhubeka rhoqo. Lo gama nje usebenza kakuhle, amehlo ethu ahlala esempilweni.
Ziziphi iimeko eziqhelekileyo ezichaphazela igumbi elingaphambili?
Imiba echaphazela igumbi elingaphambili inokwahlulwahlulwa ibe ziindidi ezine eziphambili.
- Uxinzelelo oluphezulu kwigumbi elingaphambili.
- Uxinzelelo oluphantsi kwigumbi elingaphambili.
- Utshintsho kubungakanani okanye kwimo yegumbi elingaphambili.
- Izinto ezingaqhelekanga ezingena kwigumbi elingaphambili.
Uxinzelelo oluphezulu ngaphakathi kweliso
Njengoko benditshilo ngaphambili, kufuneka kubekho uxinzelelo ngaphakathi kweliso. Kodwa ukuba olu xinzelelo lunyuka kakhulu (i-Ocular Hypertension) , lubangela ukuba iindawo ezingaphakathi kweliso zityhalele umva. Olu xinzelelo luqala ukonakalisa umthambo wokubona . Yiloo nto siyibiza ngokuba yi-glaucoma . Ukuba ayinyangwa kakuhle, inokukhokelela ekubeni yimfama. I-Glaucoma yeyona nto iphambili ebangela ubumfama ehlabathini.
Uxinzelelo oluphantsi lwangaphakathi kweso
Njengokuba uxinzelelo oluphezulu lunokuba yingozi, uxinzelelo oluphantsi lunokuba yingozi. Oku kubizwa ngokuba yi-ocular hypotension . Ukuba oku kuyenzeka, iliso linokuvuvukala, njengebhaluni ephuma amanzi. Le yingxamiseko yezonyango. Oku kunokukhokelela kumonakalo ongunaphakade kweliso kunye nokungaboni. Ukulimala kwamehlo kunye notyando kunokubangela ukuba ulwelo luphume kwigumbi elingaphambili, okubangela ukuba uxinzelelo lwehle.
Utshintsho kwimilo okanye ubungakanani begumbi elingaphambili
Abanye abantu bazalwa benegumbi elingaphantsi elincinane okanye elinganzulu kangako. Oku kwenza kube lula ukuba indlela ehamba ngayo ulwelo ivaleke. Oku kwandisa uxinzelelo ngaphakathi kweliso, okwandisa umngcipheko wokuba ne-glaucoma.
Izinto ezingafanelekanga kwigumbi elingaphambili
Ngamanye amaxesha, izinto ezingezizo ezo ndawo zinokungena kolu lwelo (ihlaya lamanzi). Umzekelo:
- Iziqwenga zemibala: Iziqwenga zemibala kwinxalenye enombala yeliso (iris) zinokuqhekeka zingene kolu lwelo. Oku kubizwa ngokuba yiPigmentary Dispersion Syndrome . Ukuba ezi ziqwenga ziyaqhekeka zize zivale inkqubo yokukhupha amanzi, uxinzelelo luyanda kwaye kuvela iglaucoma.
- Usulelo: Ukuba iintsholongwane okanye ezinye iintsholongwane zingena elisweni, usulelo olubi olubizwa ngokuba yi-endophthalmitis lunokukhula.
- Iiseli zomhlaza: Ukuba umhlaza uvela ngaphakathi kweliso (i-intraocular melanoma) , ezo seli zinokuqokelelana kolu lwelo.
- Ukudumba: I-Uveitis (ukudumba kweliso) inokubangela ukuba olu lwelo lube mdaka kwaye lubangele iingxaki.
Zithini iimpawu zolu hlobo lwengxaki?
Kukho iimpawu ezininzi ezinokwenzeka xa kukho ingxaki kwigumbi elingaphambili. Ezinye zibonakala ngequbuliso, ngelixa ezinye zinokuvela kancinci kancinci. Kubaluleke kakhulu ukukwazi oku.
| Uphawu | Inkcazo |
|---|---|
| Ukuba unale mpawu, bonana nogqirha ngokukhawuleza! | |
| Ukuzaliswa kwegazi ngaphakathi kweliso (Hyphema) | Igazi lihlangana phambi kweliso elimnyama. Oku kungaba luphawu lwengozi enkulu. |
| Amehlo amakhulu okanye avele ngaphandle (iBuphthalmos) | Amehlo, ingakumbi kubantwana abancinci, abonakala emakhulu ngendlela engaqhelekanga. |
| Isicaphucaphu nokuhlanza kunye nentlungu yamehlo | Isenokuba luphawu lokunyuka ngequbuliso koxinzelelo lwamehlo (i-Acute Glaucoma). |
| Ukubona izangqa zomnyama zijikeleze ukukhanya | Ukubona imibala emininzi ejikeleze ibhalbhu okanye isibane xa usijonga. |
| Ukulahlekelwa ngumbono ngequbuliso | Ukulahlekelwa ngumbono ngequbuliso, nokuba kuphelele okanye kuncinci, ngaphandle kwesizathu esicacileyo. |
| Iimpawu ezibonakala kancinci kancinci kodwa ezifanele ukuqwalaselwa | |
| Intlungu yamehlo okanye ubunzima | Ukuva intlungu enzulu okanye uxinzelelo oluvela ngaphakathi kweliso. |
| Intloko ebuhlungu | Intloko ebuhlungu, ingakumbi ejikeleze amehlo. |
| Ubomvu bamehlo | Amehlo abomvu rhoqo. |
| Umbono ofipheleyo | Ukulahleka kancinci kancinci kombono ngokuhamba kwexesha. |
Into ebalulekileyo kukuba ngamanye amaxesha iimeko ezifana ne-glaucoma azibonisi zimpawu kwasekuqaleni. Yiyo loo nto kubalulekile ukuba uhlolwe amehlo akho rhoqo.
Ziziphi iindlela zokuhlola igumbi elingaphambili?
Xa undwendwela ugqirha wamehlo, uza kuhlola igumbi lakho langaphambili njengenxalenye yovavanyo oluqhelekileyo. Iimvavanyo ezahlukeneyo zingasetyenziselwa le njongo.
- Uvavanyo lweLampu yeSilayidi: Kusetyenziswa imakroskopu ekhethekileyo ukukhulisa ingaphakathi lelihlo lakho, njengegumbi elingaphambili kunye nelensi.
- I-Tonometry: Le isetyenziselwa ukulinganisa uxinzelelo ngaphakathi kweliso. Oku kubaluleke kakhulu ekufumaneni i-glaucoma.
- I-Gonioscopy: Oku kujonga ukuba i-engile yokukhupha amanzi, ekhupha ulwelo kwi-engile yegumbi elingaphambili, ivulekile okanye ivaliwe.
- I-Pachymetry: Oku kulinganisa ubukhulu be-cornea. Oku kunceda nokuvavanya ngokuchanekileyo uxinzelelo lwamehlo.
Ukongeza kwezi, ugqirha wakho unokukuthumela kwezinye iimvavanyo ezithile ngokuxhomekeke kwiimpawu zakho.
Singenza ntoni ukuze sikhusele amehlo ethu?
Zininzi izinto onokuzenza ukuze ugcine amehlo akho esempilweni, kuquka negumbi elingaphambili.
- Eyona nto ibalulekileyo kukuhlolwa amehlo rhoqo . Nokuba awuzinxibi iiglasi, bonana nogqirha wamehlo ubuncinci rhoqo emva kweminyaka emibini ukuze uhlolwe amehlo ngokupheleleyo. Ukuba unembali yosapho lwakho enezigulo ezifana neglaucoma, kulungile ukuba uhlolwe kwangoko.
- Khusela amehlo akho. Qiniseka ukuba unxiba iiglasi zokhuseleko xa udlala imidlalo, usebenza egadini, usebenza ngoomatshini, kwaye usebenzisa iikhemikhali.
