Okudingeka ukwazi nge-'Anterior Chamber' ngaphakathi kweso

Wake wazibuza ukuthi kungakanani okwenzeka ngaphakathi kwalesi sitho esincane esibizwa ngokuthi iso lethu, ukuthi sisebenza kanjani? Iso liyindalo emangalisayo ngempela. Namuhla sizokhuluma ngengxenye ebaluleke kakhulu yeso esingakhulumi kakhulu ngayo. Leyo 'igumbi elingaphambili' leso, noma ngokwezokwelapha , i-Anterior Chamber . Nakuba le ndawo incane, iyingxenye ebalulekile yokubona kwakho.

Kalula nje, iyini le gumbi elingaphambili?

Kulula kakhulu. Ingxenye ecacile, eyindilinga engaphambili kwelihlo lakho ibizwa ngokuthi i-cornea . Isikhala esincane ngemuva kwe-cornea sibizwa ngokuthi ikamelo elingaphambili. Leli gumbi alinalutho nje kuphela. Ligcwele uketshezi olukhethekile ngaphakathi. Sibiza lolo ketshezi ngokuthi i-aqueous humor .

Manje ungase ucabange, "Iyini le ndawo encane kanye nalo lonke uketshezi olukuyo?" Lokhu empeleni kufeza indima ebaluleke kakhulu.

Zicabange uthatha ilensi eqondile futhi ukhulisa okuthile. Ukuze ukubone kahle, kumele kube nebanga elithile phakathi kwento, ilensi, kanye neso lakho. Yileyo ndlela amehlo ethu anjalo. Sidinga ukugcina ibanga elithile phakathi kwelensi, i -retina, kanye ne-cornea engaphakathi kwamehlo ethu.

Igumbi elingaphambili libalulekile ekugcineni leli banga. Uketshezi olungaphakathi kwalo (Aqueous Humor) ludala ingcindezi ethile ngaphakathi kweso. Lokhu sikubiza ngokuthi ingcindezi yangaphakathi kweso . Njengoba nje uma uphefumula umoya ube yibhola, liyafutha bese libuyela esimweni salo esifanele, kungenxa yalokhu kucindezela ukuthi inhlamvu yeso 'ifutha', okungukuthi, inesimo esifanele. Yingakho zonke izingxenye zeso zisezindaweni ezifanele, futhi sikwazi ukubona kahle.

Lolu ketshezi (aqueous humor) luhamba kanjani ngaphakathi kweso?

Lena inqubo emangalisayo kakhulu. Uma konke kusebenza kahle ngaphakathi kwamehlo ethu, lolu ketshezi (Aqueous Humor) luyakhiqizwa, lunyakaze, futhi lususwe ngenani elidingekayo. Lokhu kunikeza amehlo ukudla okunomsoco nomoya-mpilo, futhi kusiza nesimiso somzimba sokuzivikela samehlo. Ibhalansi yalolu ketshezi ibaluleke kakhulu. Uma uketshezi lukhuphuka, umfutho wamehlo uyanda, futhi uma luncipha, umfutho uyancipha. Akukho kulokhu okuhle emehlweni.

Nansi indlela le nqubo esebenza ngayo:

1. Lo msindo wamanzi uqala ukwenziwa yingxenye yeso ebizwa ngokuthi umzimba we-ciliary .

2. Lolu ketshezi lugeleza luye ' ekamelweni elingemuva ' ngemuva kwengxenye enombala yeso, i-iris .

3. Ukusuka lapho, iso lidlula kumfundi bese lingena ' eKamelweni Elingaphambili ' esikhuluma ngalo.

4. Ngemva kokuba igumbi elingaphambili seligcwele, uketshezi oluningi ludinga ukuphuma. Lokhu kwenzeka ngohlelo olukhethekile lokukhipha amanzi ekhoneni legumbi elingaphambili. Silubiza ngokuthi i-Trabecular Meshwork .

5. Uketshezi oludlula kulolu hlelo lokukhipha amanzi lugcina luqoqana emithanjeni yegazi engxenyeni emhlophe yeso (i-sclera) bese luhlangana negazi.

Lo mjikelezo uqhubeka njalo. Uma nje usebenza kahle, amehlo ethu ahlala ephilile.

Yiziphi izimo ezivamile ezithinta ikamelo elingaphambili?

Izinkinga ezithinta igumbi elingaphambili zingahlukaniswa ngezigaba ezine eziyinhloko.

• Ukwanda kwengcindezi ekamelweni elingaphambili.
• Ukuncipha kwengcindezi ekamelweni elingaphambili.
• Izinguquko ngobukhulu noma ukuma kwegumbi elingaphambili.
• Izinto ezingavamile ezingena ekamelweni elingaphambili.

Ukucindezela okwandayo ngaphakathi kweso

Njengoba ngishilo ngaphambili, kufanele kube nokucindezeleka ngaphakathi kweso. Kodwa uma lokhu kucindezela kukhula kakhulu (i-Ocular Hypertension) , kubangela ukuthi izingxenye ezingaphakathi kweso zibuyele emuva. Lokhu kucindezela kuqala ukulimaza i -optic nerve . Yilokho esikubiza ngokuthi i-glaucoma . Uma ingelashwa kahle, ingaholela ngisho nasekungabonini. I-Glaucoma iyimbangela ehamba phambili yobumpumputhe emhlabeni.

Ukuncipha kwengcindezi yangaphakathi kweso

Njengoba nje ukucindezeleka okuphezulu kungaba yingozi, ukucindezeleka okuphansi kungaba yingozi. Lokhu kubizwa ngokuthi i-ocular hypotension . Uma lokhu kwenzeka, iso lingavuvukala, njengebhaluni eliphumile. Lesi yisimo esiphuthumayo sezokwelapha. Lokhu kungaholela ekulimaleni okungapheli kweso kanye nokungaboni. Ukulimala kwamehlo kanye nokuhlinzwa kungabangela ukuvuza koketshezi kusuka ekamelweni elingaphambili, okubangela ukucindezeleka kwehle.

Izinguquko esimweni noma ngobukhulu begumbi elingaphambili

Abanye abantu bazalwa benegumbi elingaphansi elincane noma elingajulile. Lokhu kwenza kube lula ukuthi indlela okugeleza ngayo uketshezi ivaleke. Lokhu kwandisa ingcindezi ngaphakathi kweso, okwandisa ingozi yokuthola i-glaucoma.

Izinto ezingafaneleki endaweni engaphambili

Ngezinye izikhathi, izinto ezingezona ezalapho zingangena kulolu ketshezi (aqueous humor). Isibonelo:

• Izingcezu zemibala: Izingcezu zemibala engxenyeni enombala yeso (iris) zingaphuka zingene kulolu ketshezi. Lokhu kubizwa ngokuthi i-Pigmentary Dispersion Syndrome . Uma lezi zingcezu ziphuka futhi zivimba uhlelo lokukhipha amanzi, ingcindezi iyanda futhi kuvele i-glaucoma.
• Ukutheleleka: Uma amabhaktheriya noma amanye amagciwane engena esweni, ukutheleleka okukhulu okubizwa ngokuthi i-endophthalmitis kungavela.
• Amaseli omdlavuza: Uma umdlavuza uvela ngaphakathi kweso (i-intraocular melanoma) , lawo maseli anganqwabelana kulolu ketshezi.
• Ukuvuvukala: I-Uveitis (ukuvuvukala kweso) ingabangela nokuthi lolu ketshezi lungcole futhi lubangele izinkinga.

Ziyini izimpawu zalolu hlobo lwenkinga?

Kunezimpawu eziningana ezingase zivele uma kunenkinga ekamelweni elingaphambili. Ezinye zivele ngokuzumayo, kanti ezinye zingase zivele kancane kancane. Kubaluleke kakhulu ukuqaphela lokhu.

Yiziphi izindlela zokuhlola ikamelo elingaphambili?

Uma uvakashela udokotela wamehlo, uzohlola ikamelo lakho langaphambili njengengxenye yokuhlolwa okuvamile. Kungasetshenziswa izivivinyo ezahlukahlukene ngale njongo.

• Ukuhlolwa Kwesibani Esiqhekekile: Kusetshenziswa i-microscope ekhethekile ukukhulisa ingaphakathi leso lakho, njengegumbi elingaphambili kanye nelensi.
• I-Tonometry: Lokhu kusetshenziselwa ukukala ingcindezi engaphakathi kweso. Lokhu kubaluleke kakhulu ekutholeni i-glaucoma.
• I-Gonioscopy: Lokhu kuhlola ukuthi i-engeli yokukhipha amanzi, ekhipha uketshezi oluvela ekhoneni legumbi elingaphambili, ivulekile noma ivaliwe.
• I-Pachymetry: Lokhu kulinganisa ukujiya kwe-cornea. Lokhu kusiza futhi ekuhloleni ngokunembile ukucindezeleka kwamehlo.

Ngaphezu kwalokhu, udokotela wakho angakuthumela kwezinye izivivinyo ezithile kuye ngezimpawu zakho.

Yini esingayenza ukuze sivikele amehlo ethu?

Kunezinto eziningana ongazenza ukuze ugcine amehlo akho ephilile, okuhlanganisa negumbi elingaphambili.

• Into ebaluleke kakhulu ukuhlolwa kwamehlo njalo . Ngisho noma ungazigqoki izibuko, bona udokotela wamehlo okungenani njalo eminyakeni emibili ukuze uhlolwe amehlo ngokuphelele. Uma unomlando womndeni wezimo ezifana ne-glaucoma, kuwukuhlakanipha ukuhlolwa ngokushesha.
• Vikela amehlo akho. Qiniseka ukuthi ugqoka izibuko zokuphepha lapho udlala imidlalo, usebenza engadini, usebenza ngemishini, futhi usebenzisa amakhemikhali.
• Lawula izifo zakho ezingamahlalakhona.Uma unezifo ezifana nesifo sikashukela noma umfutho wegazi ophakeme, zilawule ngendlela efanele, njengoba lezi zifo zithinta ngqo impilo yamehlo.
• Nakekela impilo yakho iyonke. Yidla ukudla okunempilo. Gcina isisindo esinempilo esikufanele. Lezi zinto zibaluleke kakhulu empilweni yamehlo akho.

Igumbi elingaphambili liyingxenye yeso lethu ephambi kwamehlo ethu futhi libalulekile kithi ukuze sibone umhlaba. Ngakho-ke, uma uhlangabezana nanoma yiziphi izimpawu zamehlo, ungazinaki. Ukuthola ukuxilongwa okufanele kanye nokwelashwa ngesikhathi kungasiza ekuvikeleni umbono wakho oyigugu.
