Izinyembezi zifika kanjani emehlweni akho? Ake sixoxe nge-Lacrimal Apparatus!

Sonke sinezikhathi lapho sidabukile, sijabule, futhi ngezinye izikhathi simane nje sinamehlo agcwele izinyembezi, akunjalo? Kodwa wake wazibuza ukuthi lezi zinyembezi zakheka kanjani ngempela, kungani sinezinyembezi, futhi iyini indlela emangalisayo esetshenziswayo lokhu? Leso yisimiso esihle sezinyembezi esivikela futhi simanzise amehlo ethu, noma njengoba sibizwa kanjalo kwezesayensi yezokwelapha, "i-Lacrimal Apparatus", okuyilokho esizokhuluma ngakho namuhla.

Iyini uhlelo lwezinyembezi? Kungani lubalulekile kithi?

Kalula nje, uhlelo lwakho lokudabuka luyinethiwekhi eyinkimbinkimbi yezindlala, amasaka, kanye nemigudu eyenza izinyembezi emehlweni akho futhi isuse izinyembezi esezisetshenzisiwe. Unezinhlelo ezimbili zalezi, eyodwa yeso ngalinye.

Cabanga ngakho njengohlelo lokunisela olugcina utshani bakho buluhlaza futhi buluhlaza. Njengoba nje kukhona ama-sprinkler anisela ingadi yakho, amapayipi angaphansi komhlaba, kanye nohlelo lokukhipha amanzi olukhipha amanzi amadala, lolu hlelo lokuklebhula lusebenza futhi ukugcina amehlo ethu ephilile futhi emanzi.

Izinyembezi ezikhiqizwa yilolu hlelo, olwaziwa nangokuthi 'uketshezi lwe-lacrimal' ngokwezokwelapha, zimanzisa futhi zithambise ubuso bamehlo ethu. Zivikela izindawo ezibucayi, ikakhulukazi ulwelwesi lwangaphandle lomhlophe weso 'conjunctiva' kanye nolwelwesi olubonakalayo olumboza umnyama weso 'cornea'. Akukhona lokho kuphela, lezi zinyembezi ziphinde zihlanze uthuli, ukungcola, kanye nezinto ezibangela ukungezwani komzimba ezingena esweni. Inzwa ebusweni bethu, 'i-Facial Nerve noma i-Seventh Cranial Nerve', ilawula imisipha epompa lezi zinyembezi esweni futhi izisuse.

Izinyembezi zakheka kanjani futhi zigeleza kanjani?

Indawo eyinhloko lapho kukhiqizwa khona izinyembezi kusezinhlayiyeni ze-lacrimal, ezitholakala ngaphandle kwamehlo akho. Yilapho kukhiqizwa khona ingxube kasawoti namanzi. Uma ucwayiza, lolu ketshezi lusakazeka kulo lonke iso lakho. Lube seluxutshwa noketshezi olunamafutha oluvela kolunye uhlobo lwe-gland, izinhlayiya ze-meibomian, ezitholakala emaphethelweni amajwabu akho. Yilapho-ke kwakheka khona ithonsi eligcwele lezinyembezi.

Lolu ngqimba olunamafutha lubaluleke kakhulu ngoba luvimba amanzi ukuthi angashisi ngokushesha. Futhi, inani elincane lala mafutha lihlala emaphethelweni ejwabu futhi livimbele izinyembezi ukuthi zingagelezi ejwabu.

Ngakho-ke, ngemva kokuhlanza nokumanzisa amehlo akho, lezi zinyembezi ezindala zidinga ukukhishwa emehlweni akho. Yilokho okwenziwa uhlelo lwemibhobho yezinyembezi. Lezi zinyembezi zidlula ezimbotsheni ezincane ohlangothini lwekhala lakho bese ziqoqana ngemuva kwekhala lakho. Yingakho uma ukhala kakhulu, ikhala lakho lizizwa likhungathekile futhi uthola ikhala eligobhozayo. Izinyembezi ezengeziwe zingena ekhaleni lakho nasemphinjeni wakho.

Yiziphi izingxenye eziyinhloko zesistimu yokudabuka?

Manje ake sibheke izingxenye eziyinhloko ezakha lonke lolu hlelo lokudabuka.

• Izindlala zeLacrimal:Lezi zifana nezimboni ezinkulu ezenza izinyembezi. Lezi zindlala zitholakala ngaphansi nje kwejwabu lakho eliphezulu, ngasekhoneni elingaphandle lejwabu lakho. Zicishe zibe usayizi we-alimondi encane. Zikhiqiza amanzi anosawoti ezinyembezini zethu.

• Izindlala zeMeibomian: Lezi zitholakala emaphethelweni ezinkophe zakho ezingaphezulu nangaphansi. Lezi zindlala zikhiqiza uketshezi olunamafutha olwenza izinyembezi zakho. Lawa mafutha, axutshwe namanzi avela ezinkopheni zezinyembezi, asiza ekwakheni ifilimu yezinyembezi ebusweni beso lakho. Lolu ngqimba olunamafutha lusiza ukugcina amehlo akho emanzi isikhathi eside, luvimbele izinyembezi zakho ukuthi zingashisi ngokushesha.

• I-Lacrimal Puncta: Lezi yizimbobo ezincane ezikhipha izinyembezi ezisetshenzisiwe emehlweni akho. Lezi zimbobo (i-punctum - eyodwa, i-puncta - ubuningi) zitholakala emakhoneni angaphakathi ezinkopheni zakho zamehlo eziphezulu nezangaphansi, ngasekhaleni lakho. Njalo uma ucwayiza, lezi zimbobo zisebenza njengama-valve amancane, zikhipha izinyembezi ezindala emehlweni akho.

• Amasaka E-Lacrimal: Izinyembezi eziphuma emigudwini yezinyembezi ziqoqana kulezi zikhwama ze-lacrimal. Lezi zitholakala ekhoneni elingaphakathi leso, kuzo zombili izinhlangothi zekhala. Lezi zikhwama zisebenza njengethangi elincane lesikhashana elivimba izinyembezi ezindala ukuthi zingaphindeli emuva emigudwini yezinyembezi.

• Ipayipi Lokudabula Ikhala (Ipayipi Lokudabula Ikhala): Lezi yizinto esivame ukuzibiza ngokuthi ipayipi lokudonsa izinyembezi. Izinyembezi ezindala eziphuma emifuleni yokudonsa izinyembezi kanye nezikhwama zokudonsa izinyembezi zigcina zigeleza kule misele kuzo zombili izinhlangothi zekhala. Le misele iphela ngemuva kwekhala. Njengoba sishilo ngaphambili, yingakho amanzi ephuma ekhaleni lakho uma ukhala.

Cabanga nje, zonke lezi zingxenye zixhumene futhi zisebenza njengeqembu, yingakho amehlo ethu ehlala ephilile futhi ehlanzekile. Uma kunenkinga encane engxenyeni eyodwa, ingathinta lonke uhlelo.

Yiziphi izimo ezivamile ezithinta uhlelo lwethu lwezinyembezi?

Ngezinye izikhathi, kungavela izinkinga ezahlukahlukene kulesi simiso sokukhala. Nazi ezinye zezimo ezivame kakhulu esibhekana nazo uma lokhu kwenzeka:

• Amehlo Omile: Lena inkinga evamile kubantu abaningi. Uma amehlo engakhiqizi izinyembezi ezanele, noma lapho ikhwalithi yezinyembezi azikhizayo yehla (isibonelo, lapho inani lamafutha akhiqizwa yizindlala ze-meibomian lehla), amehlo angaba omile, abomvu, futhi alume. Ngezinye izikhathi, kungazwakala sengathi kukhona okuthile emehlweni.

• Ukudabuka ngokweqile (i-Epiphora): Lokhu kuphambene nalokho. Kuzwakala sengathi kunezinyembezi eziningi kakhulu eziphumayo, futhi ngezinye izikhathi izinyembezi zingase zehle ezihlathini zakho. Lokhu kungase kube ngenxa yokwanda kokukhiqizwa kwezinyembezi, noma kungase kube ngenxa yokuvaleka kwemigudu yokudonsa izinyembezi okuvimbela izinyembezi ukuthi zingaphumi kahle.

• Ukuvalwa Kwepayipi Lasekhaleni:Lesi simo sivame kakhulu ezinganeni ezincane. Ngenxa yokuthi imigudu yokukhala ayivuleki ngokuphelele, izinyembezi zinganqwabelana ngaphakathi kweso, ngezinye izikhathi okuholela ezifweni.

• I-Dacryoadenitis: Lokhu ukuvuvukala nokuvuvukala kwezindlala zezinyembezi . Lokhu kungabangelwa ukutheleleka noma ezinye izimbangela.

• I-Dacryocystitis: Lokhu ukuvuvukala noma ukutheleleka kwesikhwama se-lacrimal. Lokhu kuvame ukubangelwa ukuvaleka komsele wokukhala izinyembezi.

Wazi kanjani ukuthi kunenkinga ngesistimu yokudabuka?

Kunezimpawu ezimbalwa ezibalulekile zokuthi ungase ube nenkinga ohlelweni lwakho lokudabuka. Into ebaluleke kakhulu ukuthi uma uzwa amehlo omile njalo, noma uma unezinyembezi ezimanzi (`Epiphora`) , kungaba uphawu lokuthi kukhona okungahambi kahle ohlelweni lwakho lokudabuka.

Cabanga nje, uma izindlala zakho zaseMeibomian zingasebenzi kahle, azikhiqizi uwoyela owanele wezinyembezi zakho. Khona-ke izinyembezi azihlali kahle emehlweni akho, futhi ziyanyamalala ngokushesha kakhulu, noma ziphele emehlweni akho. Ungase ucabange ukuthi ukhipha ezinye izinyembezi, kodwa okwenzekayo ngempela ukuthi amehlo akho awakwazi ukugcina izinyembezi azikhipha kahle.

Ngakho-ke, uma ubona noma yini ehlukile emehlweni akho - noma ngabe kuyinto encane njengamehlo omile - into engcono kakhulu ongayenza ukubonana nochwepheshe wokunakekelwa kwamehlo (Ophthalmologist) ukuze ahlolwe. Bangakwazi ukuthola ukuthi yini ngempela engalungile futhi bakunikeze ukwelashwa okudingekayo.

Sigcina kanjani uhlelo lwethu lwezinyembezi luphilile?

Njengamehlo ethu, sidinga ukunakekela ukugcina lesi simiso sezinyembezi siphilile.

• Thola ukuhlolwa kwamehlo njalo ngezikhathi ezithile: Udokotela ngeke ahlole nje kuphela ukubona kwakho, kodwa futhi nempilo yonke yamehlo akho, okuhlanganisa nokusebenza kwesistimu yakho yezinyembezi.
• Uma ubona noma yiziphi izinguquko ekuboneni kwakho, tshela udokotela wakho ngokushesha. Uma ugqoka izibuko noma ama-contact lens, zihlole njalo bese uzishintsha uma kudingeka.
• Uma unesifo esifana nesifo sikashukela, kufanele nakanjani ubonane nodokotela wamehlo okungenani kanye ngonyaka, njengoba isifo sikashukela singathinta amehlo.
• Gqoka isivikelo samehlo esifanele lapho udlala imidlalo noma wenza umsebenzi ongaba yingozi emehlweni.

Isifinyezo (Umyalezo Wokuya Nawe Ekhaya)

Cishe usuyaqonda manje ukuthi ithuluzi lethu lokuzwa ikhala aliyona nje indawo lapho kukhiqizwa khona izinyembezi, liyisimiso esibalulekile esithambisa, sivikele, futhi sigcine amehlo ethu ephilile. Izinyembezi ezikhiqizwa yilesi simiso zisiza amehlo ethu ukuba asebenze kahle futhi ahlale ephilile.

Ngakho-ke, uma uke waba namehlo omile noma umuzwa wamehlo anamanzi, ungamane nje ungakunaki njengokujwayelekile bese ubona udokotela wamehlo. Nakuba lezi zimpawu ngezinye izikhathi zingabangelwa izinto ezincane, zingaba uphawu lwesimo esingalimaza amehlo akho noma umbono wakho uma singelashwa. Kungakhathaliseki ukuthi imbangela iyini, odokotela bangasiza ekubuyiseleni ibhalansi ohlelweni lwakho lokudabuka.

Ngakho-ke, nakekela amehlo akho, ngoba ayizinto eziyigugu kakhulu ezikusiza ukuthi ubone umhlaba!
