Ziphuma njani iinyembezi emehlweni akho? Masithethe ngesixhobo seLacrimal!

Sonke sinamaxesha apho siba lusizi, sonwabile, kwaye ngamanye amaxesha simane nje sineenyembezi, akunjalo? Kodwa ngaba wakha wazibuza ukuba ezi nyembezi zenziwa njani ngokwenene, kutheni sineenyembezi, kwaye yintoni indlela emangalisayo ebangela oku? Leyo yindlela emangalisayo yokunyembeza ekhusela kwaye ifumisa amehlo ethu, okanye njengoko ibizwa kwisayensi yezonyango, ``Lacrimal Apparatus``, nto leyo esiza kuthetha ngayo namhlanje.

Yintoni inkqubo yokukrazula? Kutheni ibalulekile kuthi?

Ngamafutshane, inkqubo yakho yokukrazula yinethiwekhi entsonkothileyo yamadlala, iingxowa, kunye nemibhobho eyenza iinyembezi emehlweni akho kwaye isuse iinyembezi ezisetyenzisiweyo. Unezimbini kwezi nkqubo, enye ijongene neliso ngalinye.

Cinga ngayo njengenkqubo yokunkcenkceshela egcina ingca yakho iluhlaza kwaye iluhlaza. Njengokuba kukho izixhobo zokunkcenkceshela ezinkcenkceshela igadi yakho, imibhobho engaphantsi komhlaba, kunye nenkqubo yokukhupha amanzi amadala, le nkqubo yokukrazula ikwasebenza ukugcina amehlo ethu esempilweni kwaye emanzi.

Iinyembezi eziveliswa yile nkqubo, ekwaziwa ngokuba yi-'lacrimal fluid' ngokwezonyango, zifumisa kwaye zithambise umphezulu wamehlo ethu. Zikhusela iindawo ezibuthathaka, ngakumbi i-membrane yangaphandle yomhlophe weliso 'conjunctiva' kunye ne-membrane ecacileyo egubungela umnyama weliso 'cornea'. Ayipheleli apho, ezi inyembezi zikwahlanza uthuli, ukungcola, kunye nezinto ezibangela i-allergens ezingena elisweni. I-nerve ebusweni bethu, i-'Facial Nerve okanye i-Seventh Cranial Nerve', ilawula izihlunu ezipompa ezi inyembezi emehlweni kwaye izisuse.

Iinyembezi zakheka njani kwaye ziphuma njani?

Indawo ephambili apho kuvela khona iinyembezi kukwi-lacrimal glands, ezikwi-lacrimal glands, ezikwi-outside of your eyes. Kulapho kuvela khona umxube wetyuwa namanzi. Xa uqhwanyaza, olu lwelo lusasazeka kulo lonke iliso lakho. Emva koko luxutywa ne-oily secretions ezivela kolunye uhlobo lwe-gland, i-meibomian glands, ezikwi-edges of your eyes. Kulapho kuvela khona i-full drap drop.

Olu layer lunamafutha lubaluleke kakhulu kuba luthintela amanzi ukuba angatshi ngokukhawuleza. Kwakhona, inani elincinci lale oyile lihlala emaphethelweni eliso kwaye lithintele iinyembezi ukuba zingaphumi eliso.

Ngoko ke, emva kokuba ucoce kwaye umanzise amehlo akho, ezi nyembezi zindala kufuneka zikhutshwe emehlweni akho. Yiyo loo nto inkqubo yemibhobho yeenyembezi yenzelwe. Ezi nyembezi zidlula kwimingxuma emincinci ecaleni kwempumlo yakho zize ziqokelele ngasemva kwempumlo yakho. Yiyo loo nto xa ukhala kakhulu, impumlo yakho iziva ixinene kwaye ufumana impumlo egobhozayo. Iinyembezi ezingaphezulu zingena empumlweni yakho nasemphinjeni wakho.

Ziziphi iindawo eziphambili zenkqubo yokukrazula?

Ngoku makhe sijonge iindawo eziphambili ezenza yonke le nkqubo yokukrazula.

• Ii-Lacrimal Glands:Ezi zifana neefektri eziphambili zokwenza iinyembezi. Ezi glands zifumaneka ngaphantsi kwejwabu lakho eliphezulu, ngasekoneni engaphandle yejwabu lakho. Zilingana nobukhulu be-almond encinci. Zivelisa amanzi anetyuwa kwiinyembezi zethu.

• Ii-Meibomian Glands: Ezi zifumaneka emaphethelweni eenkophe zakho eziphezulu nezisezantsi. Ezi glands zivelisa ulwelo olunamafutha oluyila iinyembezi zakho. Le oli, ixutywe namanzi avela kwiiglands zeenyembezi, inceda ekwenzeni ulwelo oluvela kumphezulu weliso lakho. Le maleko inamafutha inceda ukugcina amehlo akho emanzi ixesha elide, ithintela iinyembezi zakho ukuba zingatshi ngokukhawuleza.

• I-Lacrimal Puncta: Le yimingxunya emincinci ekhupha iinyembezi ezisetyenzisiweyo emehlweni akho. Le mingxunya (i-punctum - isinye, i-puncta - isininzi) ikwiikona zangaphakathi zeenkophe zakho eziphezulu nezisezantsi, ngasempumlweni yakho. Ngalo lonke ixesha uqhwanyaza, le mingxunya isebenza njengezivalo ezincinci, ikhupha iinyembezi ezindala emehlweni akho.

• Iingxowa zeLacrimal: Iinyembezi eziphuma kwimibhobho yeenyembezi ziqokelelana kwezi ngxowa ze-lacrimal. Ezi zikwikona engaphakathi yeliso, kumacala omabini empumlo. Ezi ngxowa zisebenza njengetanki elincinci lexeshana elithintela iinyembezi ezindala ukuba zingabuyeli kwimibhobho yeenyembezi.

• I-Nasolacrimal Duct (Ii-Knock Ducts): Ezi zizinto esizibiza ngokuba yi-cnock ducts. Iinyembezi ezindala eziphuma kwi-cnock ducts nakwii-cnock sacs ekugqibeleni ziphuma kule ducts kumacala omabini empumlo. Le ducts iphela ngasemva kwempumlo. Njengoko besitshilo ngaphambili, yingakho amanzi ephuma empumlweni yakho xa ulila.

Khawucinge nje, zonke ezi ndawo zidibene kwaye zisebenza njengeqela, yiyo loo nto amehlo ethu ehlala esempilweni kwaye ecocekile. Ukuba kukho ingxaki encinci kwenye indawo, inokuchaphazela yonke inkqubo.

Ziziphi iimeko eziqhelekileyo ezichaphazela inkqubo yethu yokukrazula iinyembezi?

Ngamanye amaxesha, iingxaki ezahlukeneyo zinokuvela kule nkqubo yokukrazula. Nazi ezinye zezona meko zixhaphakileyo esizifumanayo xa oku kusenzeka:

• Amehlo Omileyo: Le yingxaki eqhelekileyo kubantu abaninzi. Xa amehlo engaveli ngokwaneleyo iinyembezi, okanye xa umgangatho weinyembezi eziveliswayo uncipha (umzekelo, xa ubungakanani beoyile eveliswa zii-meibomian glands buncipha), amehlo anokuba omile, abe bomvu, kwaye arhawuzelele. Ngamanye amaxesha, kunokuvakala ngathi kukho into emehlweni.

• Ukukrazula okugqithisileyo (Epiphora): Oku kuchasene noko. Kuvakala ngathi kukho iinyembezi ezininzi eziphumayo, kwaye ngamanye amaxesha iinyembezi zinokuhla ezidleleni zakho. Oku kusenokubangelwa kukwanda kwemveliso yeinyembezi, okanye kusenokubangelwa kukuvaleka kwemibhobho yeinyembezi okuthintela iinyembezi ukuba zingaphumi kakuhle.

• Ukuvaleka kweMibhobho yeNkumba:Le meko ixhaphake kakhulu kwiintsana ezincinci. Ngenxa yokuba imibhobho yokukrazula ayivuleki ngokupheleleyo, iinyembezi zinokuqokelelana ngaphakathi kweliso, ngamanye amaxesha zikhokelele kwiintsholongwane.

• I-Dacryoadenitis: Oku kukudumba kunye nokudumba kwamadlala eenyembezi . Oku kunokubangelwa lusulelo okanye ezinye izizathu.

• I-Dacryocystitis: Oku kukudumba okanye usulelo lwe-lacrimal sac. Oku kudla ngokubangelwa kukuvaleka kombhobho wokukrazula.

Uyazi njani ukuba kukho ingxaki kwinkqubo yokukrazula?

Kukho iimpawu ezimbalwa ezibalulekileyo zokuba usenokuba unengxaki kwinkqubo yakho yokukrazula iinyembezi. Eyona nto ibalulekileyo kukuba ukuba uhlala uziva amehlo omile, okanye ukuba uneenyembezi ezimanzi (`Epiphora`) , oko kungaba luphawu lokuba kukho into engalunganga kwinkqubo yakho yokukrazula iinyembezi.

Khawucinge nje, ukuba ii-Meibomian Glands zakho azisebenzi kakuhle, azivelisi ioyile eyaneleyo yokulila. Emva koko iinyembezi azihlali emehlweni akho kakuhle, kwaye ziyaphela ngokukhawuleza, okanye ziphele emehlweni akho. Usenokucinga ukuba ukhupha ezinye iinyembezi, kodwa into eyenzekayo kukuba amehlo akho awakwazi ukugcina iinyembezi azivelisayo kakuhle.

Ngoko ke, ukuba ubona into eyahlukileyo emehlweni akho – nokuba yinto encinci njengamehlo omileyo – eyona nto ingcono onokuyenza kukubona ingcali yokhathalelo lwamehlo (Ophthalmologist) ukuze ihlolwe. Banokufumanisa ukuba yintoni kanye kanye ingxaki baze bakunike unyango olufunekayo.

Singayigcina njani inkqubo yethu yokukrazula iinyembezi isempilweni?

Njengamehlo ethu, kufuneka siqaphele ukugcina le nkqubo yokukrazula iphilile.

• Fumana uhlolo lwamehlo rhoqo: Ugqirha akayi kujonga kuphela ukubona kwakho, kodwa nempilo iyonke yamehlo akho, kuquka nokusebenza kwenkqubo yakho yokukrazula iinyembezi.
• Ukuba ubona naluphi na utshintsho ekuboneni kwakho, xelela ugqirha wakho ngoko nangoko. Ukuba unxiba iiglasi okanye iilensi zokunxibelelana, mazihlolwe rhoqo kwaye mazitshintshwe ukuba kuyimfuneko.
• Ukuba unesifo esifana nesifo seswekile, ngokuqinisekileyo kuya kufuneka ubone ugqirha wamehlo ubuncinane kanye ngonyaka, njengoko isifo seswekile sinokuchaphazela amehlo.
• Nxiba isikhuselo samehlo esifanelekileyo xa udlala imidlalo okanye usenza umsebenzi onokuba yingozi emehlweni.

Isishwankathelo (Umyalezo Wokuya Ekhaya)

Mhlawumbi uyaqonda ngoku ukuba isixhobo sethu sokukrala asiyondawo nje apho kuvela khona iinyembezi, yinkqubo ebalulekileyo ethambisa, ikhusela, kwaye igcina amehlo ethu esempilweni. Iinyembezi eziveliswa yile nkqubo zinceda amehlo ethu ukuba asebenze kakuhle kwaye ahlale esempilweni.

Ngoko ke, ukuba ukhe wajongana namehlo omileyo okanye uzive ngathi amehlo akho agcwele amanzi, musa ukungayinaki nje into eqhelekileyo uze ubone ugqirha wamehlo. Nangona ezi mpawu ngamanye amaxesha zinokubangelwa zizinto ezincinci, zinokuba luphawu lwemeko enokwenzakalisa amehlo akho okanye umbono wakho ukuba ayinyangwa. Nokuba yintoni na imbangela, oogqirha banokukunceda ukubuyisela ibhalansi kwinkqubo yakho yokukrazula.

Ngoko ke, khathalela amehlo akho, kuba zezona zinto zixabisekileyo ezikunceda ubone ihlabathi!
