Unayo amehlo obomvu, anamehlo? Kungenzeka ukuthi ubhekene nesimo esithinta izigidi zabantu baseMelika: izifo zeso. Izifo zamehlo ngezinye izikhathi zibangela ukunganaki okukhulu, ngokuvamile ziphazamisa imisebenzi yansuku zonke nezimpawu ezicasulayo.
Izimbangela
Umuntu uhlakulela isifo somzimba lapho isimiso somzimba sokuzivikela sithinta kakhulu i-allergen. I-allergen iyigama nganoma yisiphi isici esingabangela ukusabela okweqile.
Ama-allergen angatholakala ngaphakathi kwendlu noma ngaphandle futhi afaka izinto ezinjengotshani, umuthi nokhula we-pollen, uthuli, nesilwane sesilwane. Lapho evezwa lezi zifo, amangqamuzana emehlo akhulula i-histamines namanye amakhemikhali ngomzamo wokuvikela amehlo. Yilokho ukusabela kwamakhemikhali okubangela ukuthi imithwalo yegazi ingene ngaphakathi kwamehlo ukuvuvukala, futhi amehlo abe yinhlanzi, obomvu namanzi. Amagciwane angabangela nezinye izinkinga, njenge- conjunctivitis (iso elincane) .
Izinhlobo ze-Eye Allergy
Amagciwane omzimba ngokuvamile ahlukaniswe ngezigaba ezimbili: i-conjunctivitis ye-allergenic (SAC) kanye ne-endergical conjunctivitis (PAC) ehlala njalo.
- I-SAC:
Uhlobo oluvame kakhulu lwamehlo okungahambi kahle; abantu abathintekayo yi-SAC izimpawu zabo ngezikhathi ezithile zonyaka. - I-PAC:
Lezi zinhlobo zezilonda zamehlo zivame ukubangelwa uthuli, isilwane sezilwane noma ezinye izifo ezivame ukwenziwa unyaka wonke.
Izimpawu
Izimpawu ezilandelayo zivame ukwenzeka nge-eye allergies:
- Itching
- Ukubomvu
- Ukukhipha
- Ukuvuvukala
- Ukuvutha
- Umbono ogqamile
- I-eye mucous
Nakuba izimpawu zesifo somzimba zingase zicasule kakhulu futhi zingakhathazeki, ngokuvamile azibangeli ukulimaza amehlo.
Izingozi Zezingozi
Ukusabela kwe-eyeergic iso kwenzeka uma umuntu ezwela ku-allergen. Izifo zamehlo ngokuvamile zithinta i-conjunctiva, isembozo esicacile esihlanganisa ingxenye yangaphambili ye-eyeball.
Lesi simbozo esicacile siwuhlobo olufanayo lwezinto ezibonakala ngaphakathi kwenkemba. Ngenxa yokuthi lezi zindawo ezimbili zifana kakhulu, izifo zitholakalayo zingabangela impendulo yokugula ezindaweni zombili. Ngakho-ke, abantu abanezinyosi zomzimba bangase babe nezinkinga zokuzizwa kweso.
Ukuxilongwa
I-optometrist noma i-ophthalmologist ngokuvamile ingase ihlolwe izifo zamehlo ezisekelwe ezimpawu zesiguli. Ukuqinisekisa ukuxilongwa, udokotela wezilanga angasebenzisa isibani sokubheka ukuze ahlole ingxenye yangaphambili yeso. Lokhu kuhlolwa kungabonisa ukuba khona kwemithi ye-conjunctival kanye nejwabu leso lokuvuvukala negazi elihlanjululwayo, okuzoqinisekisa ukuxilongwa. Kwezinye izimo, udokotela angasebenzisa ithuluzi ukuze ahlasele i-conjunctiva ukuze ahlole ukutholakala kwama-eosinophils, amangqamuzana asekhona ezimweni ezinzima zokwelashwa kweso.
Ukwelapha
Imithi yokwelapha iso isobala kunazo zonke ihlanganisa ukunciphisa ukuvezwa kwezilonda ezibangelwa impendulo ye-allergenic. Lokhu kungabandakanya ukuhlala ngaphakathi endlini lapho izibalo ze-pollen ziphezulu, zifaka izibuko zokubukela ukuze zivimbele ama-pollens ukungena emehlweni, ukunciphisa inani lothuli olukhona ekhaya, nokuhlanza phansi ngesikhwama semvula esikhundleni somswakama owomile. Labo abanesifo somzimba bangase bazame nokugwema ukucasuka, njengokungcolisa ugwayi, ukungcola komoya kanye namafutha anamandla.
Ama-lens okuxhumana nawo kufanele agwenywe ngenkathi izimpawu zokungezwani zikhona, njengoba izimpawu zingabangela ukungathandeki nama-contact lensi.
Imithi
Kokubili imithi ye-prescription kanye ne-over-the-counter (OTC) ingabazuzisa kulabo ababhekene nesifo somzimba. Izinyembezi ze-OTC, ama-decongestants kanye nama-antihistamine angaphumelela ekwelapheni izimpawu zesikhashana. Izinyembezi zokuzikhandla zisiza ukuxosha ama-allergen ngaphandle kwamehlo. I-eyedrops ye-decongestant iyatholakala ngaphandle kwemithi yokusiza ukunciphisa ukubomvu kweso.
Imithi ye-prescription iphumelela kakhulu ekunciphiseni izimpawu. Ama-Antihistamine anciphisa ukucheka, ukubomvu nokuvuvukala, ngokuvamile kunalokho ngokushesha.
Ama-cell stabilizers angasetshenziswa ukusiza ukuvimbela ukukhululwa kwama-histamine, ngaleyo ndlela kunciphise izimpawu
