Ngaba wakha wajonga amehlo akho esipilini? Ungayibona isangqa esimnyama embindini wenxalenye enemibala yeliso (siyibiza ngokuba yi-iris). Yiloo nto siyibiza ngokuba yi-pupil. Ubungakanani bayo buyatshintsha ngamaxesha athile. Kodwa ngamanye amaxesha, ukuba le pupil ihlala incinci nokuba ukukhanya kutshintsha kangakanani na, inokuba luphawu lwengxaki yempilo. Yiyo leyo esiyibiza ngokuba yi-Miosis ngokwezonyango.
Ngamafutshane, yintoni iMiosis?
I-Miosis kuxa i-pupil yeliso iba ncinci kunesiqhelo, ifane nesigcawu. Ubukhulu be-pupil bulawulwa zimisipha ezikwindawo enemibala yeliso lethu, i-iris.
Njengokuba ujika amehlo xa usiya elangeni elikhanyayo, abafundi bethu nabo bayancipha ekukhanyeni okuqaqambileyo. Kwakhona, kwiindawo ezimnyama, abafundi bayakhula (bavuleke) ukuze babone ngcono. Le yinkqubo eqhelekileyo. Nangona kunjalo , kumntu one-miosis, abafundi bahlala bebancinci nokuba ukukhanya kutshintsha kangakanani na . Abanye abantu bababiza ngokuba 'zii-pinpoint pupils' kuba zifana ngqo nencam yenaliti.
Le meko inokwenzeka kwiliso elinye kuphela (elicala elinye) okanye kuwo omabini amehlo (elicala elinye).
Umahluko Phakathi kweMiosis kunye neMydriasis
Ezi zimbini ziimeko ezichaseneyo. I-Miosis kuxa iris inciphile. I-Mydriasis kuxa iris inkulu ngokungaqhelekanga (ivuleke kakhulu).
Ziziphi izizathu eziphambili ze-miosis?
Kunokubakho izizathu ezininzi zokuba iliso libe lincinci. Nangona ezinye ziqhelekile, ezinye zinokuba yingozi ngakumbi.
| Unobangela | Isiphumo |
|---|---|
| Amanye amayeza (umz., ii-opioids) | Idla ngokuchaphazela amehlo omabini . |
| Isifo sikaHorner | Icala elinye lobuso lichaphazeleka. |
| Ityhefu | Idla ngokuchaphazela amehlo omabini . |
| Ukudumba kwamehlo (i-Uveitis/Iritis) | Idla ngokuchaphazela iliso elinye , kodwa ngamanye amaxesha ingazichaphazela zombini. |
| I-Pontine Stroke | Amehlo omabini ayachaphazeleka. |
| Iintloko ezibuhlungu zeCluster | Ichaphazela icala elinye kuphela. |
1. Amanye amayeza
Amanye amayeza, ingakumbi ii-opioids, asetyenziselwa iintlungu eziqatha anokubangela ukuba i-iris ibe ncinci emehlweni omabini. Amanye amathontsi amehlo asetyenziselwa i-glaucoma, njenge-pilocarpine, nawo anokubangela oku.
2. Isifo sikaHorner
Le yimeko ebangelwa kukuphazamiseka kwemithambo-luvo ephuma engqondweni yethu iye emehlweni nasebusweni. Kule meko, iimpawu ezifana nokugoba kwamehlo kunye nokugoba kwamehlo zinokubonakala kwicala elinye lobuso.
3. Utyhefa
Le meko inokubangelwa kukutya ezinye izibulali-zinambuzane, ingakumbi ii-organophosphates . Ingabangelwa kukusebenzisa kakhulu ezinye iziyobisi, ezifana nee-benzodiazepines.
Ukuba kukho norhano oluncinci ngento enjalo, isigulana kufuneka sisiwe kwiYunithi yoNyango oluNgxamisekileyo (ETU) yesibhedlele esikufutshane ngoko nangoko. Kubaluleke kakhulu ukufowunela iZiko loLwazi lweeTyhefu zeSizwe kwiSibhedlele sikaZwelonke saseColombo ukuze ufumane ingcebiso engaphezulu.
4. Ukudumba kwamehlo
Ukudumba ngaphakathi kweliso, okubangela ukuba bomvu kwaye kube neentlungu, kunokubangela ukungasebenzi kakuhle kwe-iris. I-Uveitis kunye ne-iritis zimbini zezi meko.
5. Ukulimala Kwengqondo okanye Kwamehlo
Oku kunokwenzeka naxa into ibetha iliso ize ibangele ukwenzakala, okanye ngenxa yestroke (iPontine stroke) eyenzeka kwiindawo ezithile zobuchopho, ingakumbi i-brainstem.
6. Ezinye izizathu
Ukongeza, i-miosis inokubonwa nakwiimeko ezifana neempundu zika-Argyll Robertson, ezenzeka kwizigaba zokugqibela ze-syphilis enganyangwanga, kunye neentloko ezibuhlungu zeqela.
Masifunde nange-Miosis eyenzeka ngexesha lotyando lwe-cataract.
Ngexesha lotyando lwe-cataract, iris kufuneka ivulwe ukuze kube lula ukwenza utyando. Nangona kunjalo, ngamanye amaxesha iris inokushwabana ngequbuliso ngexesha lotyando. Oku kubizwa ngokuba yi-intraoperative miosis. Amanye amayeza, anjenge-alpha-1 antagonists yoxinzelelo lwegazi oluphezulu okanye ukwanda kwe-prostate, asemngciphekweni omkhulu. Ke ngoko, kubalulekile ukuxelela ugqirha wakho malunga nawo onke amayeza owasebenzisayo ngaphambi kokuba wenze naluphi na utyando.
Zithini iindlela zonyango zoku?
I-Miosis luphawu, ayisosifo, ngoko ke unyango lujoliswe kwimeko ebangela oko.
- Ukuba kungenxa yeyeza: Ugqirha wakho uya kugqiba ukuba aliyeke okanye alitshintshe na iyeza.
- Ukuba sisifo samehlo: uza kunikwa amayeza okulwa nokuvuvukala okanye amayeza okulwa nosulelo.
- Isifo sikaHorner: Kunokufuneka utyando ukuba lubangelwa yinto efana nethumba.
- Xa kukho isifo sohlangothi: Unyango olungxamisekileyo kufuneka lunikwe esibhedlele.
Ngaba i-Miosis ingathintelwa?
Singayithintela i-miosis ebangelwa zizizathu ezithile.
- Ukuziphepha iziyobisi: Ukuziphepha ngokupheleleyo ukusebenzisa iziyobisi, ingakumbi ii-opioids.
- Ukunxiba izixhobo zokuzikhusela: Kubaluleke kakhulu ukunxiba izixhobo zokukhusela amehlo ezifanelekileyo, ezifana neeglasi, xa udlala imidlalo okanye usenza umsebenzi onobungozi.
- Ukwazisa ugqirha wakho ngokuchanekileyo: Soloko wazisa ugqirha wakho malunga nawo onke amayeza owasebenzisayo.
Khumbula, olu hlobo lotshintsho kumbala wamehlo akho, ingakumbi ukuba lwenzeka ngequbuliso okanye luhamba nezinye iimpawu (ezifana nokungaziva mnandi kwelinye icala lobuso, intloko ebuhlungu, amehlo abomvu), lunokuba luphawu lwesifo esinzulu. Ngoko ke musa ukusityeshela.
Umyalezo Wokuya Ekhaya
- I-Miosis ngumntwana omncinci ngokungaqhelekanga, onokungasabeli kakuhle ekukhanyeni.
- Esi asisosifo, kodwa luphawu lwenye imeko.
- Izizathu zingaqala kwiimeko ezilula ukuya kwezinzima ezifana namayeza, ityhefu, izifo zemithambo-luvo, isifo sohlangothi, kunye nosulelo lwamehlo.
- Ukuba ubona olu hlobo lotshintsho kwi-iris yakho, ingakumbi ukuba luza nezinye iimpawu, bonana nogqirha ngokukhawuleza.
- Soloko wazisa ugqirha wakho malunga namayeza owasebenzisayo.
