Xa usiya kugqirha, okanye esibhedlele, mhlawumbi ukhe wambona ugqirha okanye umongikazi ethatha ithotshi encinci aze ayikhanyise emehlweni akho, akunjalo? Abanye abantu bacinga ukuba oku kukubona nje ukuba amehlo akho ayakwazi ukubona na. Kodwa eneneni, olu vavanyo lulula lunokutyhila ulwazi oluninzi olubalulekileyo malunga nempilo yamehlo ethu, kunye nempilo yomzimba wethu wonke, ingakumbi ingqondo. Masithethe ngolu vavanyo namhlanje.
Yintoni kanye kanye iPERRLA?
Ngamafutshane, i-PERRLA sisifinyezo esisetyenziswa ngoogqirha kunye neengcali zezempilo. Kufana nokufinyeza amagama ethu. Yindlela yokuba bajonge ngokulula ukuba abafundi bakho basebenza kakuhle na. Ibala elincinci elimnyama phakathi kwendandatho emnyama yeliso lakho yiloo nto siyibiza ngokuba yi-pupil. Unobumba ngamnye kwigama elithi PERRLA umele into ethile. Masibone ukuba bathetha ukuthini.
| Ileta | Intsingiselo kunye nengcaciso |
|---|---|
| Abafundi | Oku kumalunga neempundu zakho. Ezi mazibe phakathi kwenxalenye enemibala yeliso lakho (iris). |
| Ngowuphi na? | Amehlo amabini omntu ophilileyo afanele abe nee-pupil ezilinganayo ngobukhulu (ezilinganayo) . Ukuba elinye likhulu kwaye elinye lincinci, oko kungaba yingxaki. |
| Ijikelezileyo | Ii-cornea eziphilileyo mazibe ngqukuva ngokugqibeleleyo . Ukuba azilunganga, loo nto nayo ibalulekile. |
| Isabela kwi | Oku kuthetha ukuphendula. Uphendula ntoni? Ileta elandelayo iyatsho. |
| Ukukhanya | Impendulo ekukhanyeni. Xa ugqirha ekhanyisa ithotshi, i-cornea ephilileyo kufuneka inciphe ukuze ilawule ubungakanani bokukhanya okungenayo. Ebumnyameni, kufuneka ivuleke ukuze kungene ukukhanya okungakumbi. |
| Indawo yokuhlala | Oku kunzima kancinci. Kalula nje, xa ujonga into ekufutshane nento ekude, ubungakanani babafundi bakho kufuneka butshintshe. Xa ujonga into ekufutshane (umz. umnwe), abafundi baba bancinci, kwaye xa ujonga into ekude (umz. iwotshi eludongeni), abafundi baba bakhulu. Oku kuvavanya amandla amehlo akho okugxila. |
Lwenziwa njani olu vavanyo lwe-PERRLA?
Olu luvavanyo olulula kakhulu, olungenabuhlungu. Kusenokwenzeka ukuba nawe ukhe walufumana olu vavanyo.
Ngokwesiqhelo, ugqirha uza kukusa kwigumbi elimnyama kancinci aze akuhlalise esitulweni. Emva koko, baza kwenza izinto ezimbalwa ezifana nezi:
- Okokuqala, baza kujonga nje amehlo akho baze bajonge ukuba ubungakanani kunye nokuma kwee-cornea ziyafana na.
- Emva koko, uza kucelwa ukuba ujonge phambili, kwaye kuya kusetyenziswa itotshi encinci (i-penlight) ukukhanyisa ukukhanya kwelinye iliso imizuzwana embalwa, emva koko kwelinye iliso. Oku kukwabizwa ngokuba yi-"light reflex test." Oku kwenzelwa ukubona ukuba umfundi uyakhula na ukuze akhanyise.
- Ngelinye ixesha, itotshi itshintshwa ngokukhawuleza ukusuka kwelinye iliso ukuya kwelinye. Oku kubizwa ngokuba yi-"Swinging light test." Oku kunokubonelela ngolwazi olubalulekileyo malunga nokusebenza kwemithambo-luvo.
- Okokugqibela, uza kucelwa ukuba ujonge omnye weminwe yabo okanye ipeni. Emva koko baza kuyisondeza ebusweni bakho, kude, nasemacaleni. Oku kuya kuvavanya ukuba amehlo akho asebenza kakuhle na kumgama okufutshane nowakude (indawo yokuhlala).
Lonke olu vavanyo luthatha malunga nomzuzu, kodwa ulwazi olulunikayo alunakuthelekiswa nanto.
Kutheni iziphumo zolu vavanyo zibaluleke kangaka?
Ukuba iziphumo 'ziqhelekile', oko kuthetha ukuba ii-cornea zakho zisebenza kakuhle. Kodwa ukuba iziphumo 'aziqhelekanga', zinokunika izikhokelo ngezinto ezahlukeneyo. Kungaba yinto elula njengokudinga iiglasi, okanye kungaba luphawu lwesilumkiso semeko embi kakhulu engaphantsi.
Iingxaki ezinokunxulunyaniswa namehlo ngokwawo
- I-Anisocoria: Le yimeko apho ubukhulu beencam ezimbini zamehlo bahlukile. Kwabanye abantu, le isenokuba yimeko eqhelekileyo ebakho ukususela ekuzalweni. Nangona kunjalo, ukuba yenzeka ngequbuliso, kufuneka ihlolwe.
- Ukulimala kwamehlo: Xa into ibetha iliso, inokonakalisa izihlunu okanye imithambo-luvo engaphakathi.
- I-Glaucoma: Isifo apho umthambo we-optic wonakala ngenxa yoxinzelelo lwamehlo oluphezulu.
- I-Optic neuritis: Ukudumba kwemithambo-luvo edibanisa iliso nengqondo.
Iingxaki ezinokubandakanya ingqondo kunye nenkqubo yemithambo-luvo
Kukho unxibelelwano oluqinileyo phakathi kwamehlo ethu nengqondo yethu, ngoko ke utshintsho kwindlela amehlo ethu asebenza ngayo ngamanye amaxesha lunokuba luphawu lwengxaki engqondweni.
- Istroke: Ukuphazamiseka kokuhamba kwegazi ukuya engqondweni.
- Ithumba lobuchopho: Ukukhula okungaqhelekanga kweeseli engqondweni.
- I-Aneurysm: Umthambo wegazi obuthathaka engqondweni ovuthuluka njengebhaluni.
- Ukubetheka kwengqondo: Ukulimala kwengqondo okubangelwe kukubetheka entloko .
- Ukuxhuzula: Utshintsho olukhawulezileyo kumsebenzi wombane wengqondo.
Kwiimeko ezinjalo, iziphumo ezingaqhelekanga ezivela kuvavanyo lwe-PERRLA zinokuba luphawu lokuqala lokuba kufuneka uvavanyo olongezelelweyo ukuze kufunyanwe isifo . Yiyo loo nto oogqirha beqala ngokujonga amehlo ngethotshi, nokuba emva kwengozi.
Ixesha lokunyamekela amehlo akho
Olu vavanyo ludla ngokwenziwa ngugqirha, kodwa ukuba ubona into engaqhelekanga emehlweni akho, kufuneka ukhathazeke.
- Ukuba uzijonga esipilini uze ubone ukuba amehlo akho omabini awafani.
- Ukuba umbono wakho ubonakala ungacacanga ngequbuliso, okanye ukuba ubona izinto ezimbini okanye ngaphezulu.
- Ukuba unentloko ebuhlungu enganyamezelekiyo ehamba notshintsho kwindlela obona ngayo.
- Ukuba ubona utshintsho embonweni kunye nokuhlanza kunye nesiyezi emva kokubetheka entloko ndaweni ithile.
Kwimeko enjalo , bonana nogqirha ngokukhawuleza. Kwimeko yongxamiseko, njengengozi, musa ukulibazisa ukuya kwiYunithi yoNyango oluNgxamisekileyo (ETU) yesibhedlele esikufutshane.
Umyalezo Wokuya Ekhaya
- I-PERRLA yindlela elula, engenabuhlungu esetyenziswa ngoogqirha ukujonga impilo yamehlo akho.
- Olu vavanyo lulula lunokubonelela ngeenkcukacha ezibalulekileyo kungekuphela nje ngempilo yamehlo, kodwa nangeemeko ezinzulu ezinxulumene nengqondo kunye nenkqubo yemithambo-luvo.
- Ukuba ubona utshintsho olukhawulezileyo, ubona utshintsho kubukhulu be-cornea yakho, okanye wenzakele entloko , bona ugqirha ngokukhawuleza.
- Ekubeni umngcipheko wokufumana izifo zamehlo usanda ngokukhula, kubaluleke kakhulu ukuba uhlolwe amehlo rhoqo , nokuba akukho zimpawu.
