Ukukhanya okuncinci emehlweni kunokuxela lukhulu! - Singathetha ngovavanyo lweCorneal Light Reflex (uvavanyo lweHirschberg)?

Ngaba wakha weva ngolu vavanyo lubizwa ngokuba yiCorneal Light Reflex Test? Ugqirha wakho usenokuba wenze oku kuwe okanye kumntwana wakho omncinci. Luvavanyo olulula kakhulu, olungenabuhlungu olunokwenziwa ngomzuzu okanye emibini. Ukuchaneka, lwenziwa ukuze kubonwe ukuba amehlo akho alungelelene kakuhle na. Ngoko ke, masithethe kancinci ngalo, akunjalo?

Yintoni uvavanyo lweCorneal Light Reflex?

Ngamafutshane, olu luvavanyo olukhanyisa ukukhanya okuncinci kwi -cornea, inxalenye ecacileyo yenxalenye emhlophe yamehlo akho, kwaye lujonge indlela ukukhanya okukhanya ngayo ukuze kuchongwe ukuba amehlo akho ajonge okanye ajikelezwe kumacala ahlukeneyo. Oku akudingi zixhobo zintle. Okufunekayo nje sisibane esincinci (ukukhanya kwepen) kwaye igumbi lifiphale.

Olu vavanyo lwaqala ukufunyanwa yingcali yamehlo yaseJamani, uJulius Hirschberg. Yiyo loo nto lukwabizwa ngokuba luvavanyo lweHirschberg . Kulula kakhulu, akunjalo?

Ngubani odla ngokwenza olu vavanyo? Ngawaphi amaxesha?

Olu luvavanyo oluqhelekileyo kakhulu. Kukho iindlela ezahlukeneyo onokuhlangabezana nazo oku:

• Xa usiya kuhlolwa amehlo: Iingcali zamehlo okanye iingcali zamehlo ngokuqinisekileyo ziya kwenza olu vavanyo. Luyinxalenye yovavanyo lwabo lwamehlo oluqhelekileyo.
• Xa kuhlolwa uphuhliso lwabantwana abancinci: Oogqirha babantwana badla ngokwenza oku xa bezisa iintsana ezincinci kunye nabantwana abancinci ukuze batyelele rhoqo impilo-ntle yabo. Oku kubaluleke kakhulu ukuze kufunyanwe iimeko ezifana ne -strabismus okanye i-amblyopia (iliso elivila) kwasekuqaleni. Cinga ngako, abanye abantwana abancinci banokuba namehlo aphambuke kancinci kwicala elinye. Olu vavanyo lunceda ekuchongeni ngokukhawuleza ezo zinto.
• Ngexesha lokuhlolwa kwempilo kwabantu abadala minyaka le: Oogqirha banokukwenza oku ngexesha lovavanyo lwakho lomzimba okanye uvavanyo lwemithambo-luvo. Oku kuyinxalenye yenkqubo yokuhlolwa kwempilo rhoqo.

Ngoko ke ungabona, olu luvavanyo olubalulekileyo olunokwenziwa ngumntu wonke, ukususela kumntwana omncinci ukuya kumntu omdala.

Lusebenza njani olu vavanyo?

Kulula kakhulu. Ugqirha ujonga inxalenye ecacileyo yeliso lakho (i-cornea) ejikeleze indandatho emnyama , ngelixa ekhanyisa ukukhanya okuvela kwithotshi encinci emehlweni akho. Ukuba amehlo akho alungelelene ngokugqibeleleyo, ukukhanya okuvela kwithotshi kufuneka kube kwindawo enye emehlweni omabini, oko kukuthi, kwinxalenye efanayo yendandatho emnyama.

Khawuthelekelele, ukuba amehlo akho ebefana neekhamera ezimbini, okwenzekayo apha kufana nokujonga ukuba zombini ezi khamera zijolise kwindawo enye na.

Yintoni onokuyilindela ngexesha lovavanyo?

Oku kulula kakhulu. Akukho sizathu sokukhathazeka.

1. Okokuqala, ugqirha okanye ugqirha wamehlo uza kucima izibane egumbini ukuze bakwazi ukubona ngokucacileyo ukukhanya okusemehlweni akho.

2. Emva koko, ugqirha uhlala phambi kwakho aze abambe itotshi encinci esandleni sakhe ecaleni kobuso bakho.

3. Uza kuxelelwa ukuba ujonge ngqo ekukhanyeni kwelo totshi.

4. Ngelixa ulindile, ugqirha uza kujonga amehlo akho ngononophelo aze ajonge ukuba iindawo ezimbini apho ukukhanya kubonakaliswa khona ziyafana na.

Yiyo leyo. Oku kuza kuphela kwimizuzwana embalwa.

Kwenzeka ntoni emva kovavanyo?

Okwenzekayo emva kovavanyo kuxhomekeke kwinto ebonwa ngugqirha. Kukho izinto ezimbini eziphambili ezinokwenzeka:

• Ukuba amehlo akho alungelelene ngokugqibeleleyo: Akukho ngxaki. Ugqirha uza kubhala oku kwirekhodi yakho yezonyango aze adlulele kwiindawo ezilandelayo zovavanyo.
• Ukuba amehlo akho akabonakali ehambelana: Ukuba kunjalo, ugqirha wakho unokwenza ezinye iimvavanyo ezilula ukuqinisekisa ukuba ayilunganga kwaye alinganise ukuba ihamba kangakanani na. Ungakhathazeki, zonke zilula kakhulu.

Zithini iziphumo zolu vavanyo?

Ugqirha uza kukuxelela ukuba kukho na ukungahambi kakuhle kwamehlo akho, nokuba kuxa uhlolwa okanye emva kokuba ephelile.

• Ukuba amehlo akwindawo eqhelekileyo: oko kukuthi, ukuba ukukhanya kukwindawo enye emehlweni omabini, ugqirha uya kukuphawula oku kwingxelo yakho ngegama elithi "symmetry" okanye "ortho." Igama elithi "Ortho" lithetha "ngqo" ngesiGrike.
• Ukuba uneliso elijijekileyo: Ngamanye amaxesha, nokuba awunalo iliso elijijekileyo, lingabonakala ngathi lelinye. Oku kubizwa ngokuba yi-pseudostrabismus . Oku kunokubangelwa ziimpawu ezithile zobuso bakho. Umzekelo, abanye abantu banemiqolo ye-epicanthal kwiinkophe zabo, okanye utshintsho kwindawo yamathambo abo obuso, okanye ukuba umgama ukusuka embindini weliso elimnyama ukuya embindini wempumlo (umgama we-pupillary) awufani kumacala omabini. Yiyo loo nto oogqirha benza olunye uvavanyo ukuqinisekisa oku.

Ukuba kuqinisekiswa ukuba kukho ukuxhuzula emehlweni, ugqirha uya kuphawula nokuba loluphi uhlobo lokuxhuzula emehlweni. Nazi ezinye zemizekelo:

• I-Esotropia: Iliso elinye okanye omabini ajika ajonge ngaphakathi empumlweni.
• I-Exotropia: Iliso elinye okanye omabini ajika abheke ngaphandle.
• I-Hypertropia: Elinye iliso libekwe phezulu kunelinye.
• I-Hypotropia: Iliso elinye libekwe phantsi kunelinye.

Ungakhathazeki ukuba la magama abonakala enzima kuwe. Ugqirha uza kukuchazela wona ngokulula.

Ukuba iliso liqinisiwe, wenza ntoni emva koko?

Ukuba ugqirha wakho wezifo zabantwana okanye wosapho ufumanisa ukuba wena (okanye umntwana omkhathalelayo) unenyembezi elisweni lakho, baya kukuthumela kwingcali yamehlo . Ingcali yamehlo inokuxilonga unobangela wokukrazuka aze akuxelele ukuba loluphi unyango olufunekayo.

Eyona nto ibalulekileyo kukubona ezi meko kubantwana abancinci kwangethuba kwaye uqale unyango. Kulapho kuphela apho iziphumo ezilungileyo zinokufumaneka khona.

Kuthekani ukuba oku kutsalwa kubangelwa yingxaki yobuchopho?

Ngamanye amaxesha, iingcali ze-neurologists zisebenzisa olu vavanyo lwe-corneal light reflex ukujonga iingxaki zobuchopho. Umzekelo, olu vavanyo lunokuba lubalulekile kwiimeko ezifana ne-stroke okanye i-concussion . Kwiimeko ezinjalo, amanyathelo alandelayo kunye nonyango luya kuxhomekeka kwisizathu esiyintloko kunye nezinye izinto ezininzi. Ugqirha wakho uya kukuchazela oku ngelo xesha.

Ndifanele ndimbone nini ugqirha?

Njengoko ukuxhuzula kwamehlo kusanda kancinci kancinci, kunokuba nzima ukukubona ekuqaleni.

• Ukuba ubona naziphi na iimpawu zokuqhekeka kwamehlo komntwana omncinci onyamekelayo, yenza idinga nogqirha wezilwanyana ngokukhawuleza. Iimeko ezifana neliso elivilaphayo (i-amblyopia) zinokunyangwa ngokupheleleyo ukuba zinyangwa kwangethuba. Nangona kunjalo, ukuba azinyangwa emva kweminyaka ethile, zinokukhokelela ekulahlekelweni kokubona okungapheliyo. Ke ngoko, kungcono ukungalibazisi ukuxilongwa kunye nonyango.
• Ukuba umntu omdala ubona ukugoba kancinci kancinci kwamehlo, ngokuqinisekileyo kuya kufuneka ubonane nogqirha wamehlo.

Ukuba ubona ngequbuliso, kakhulu, okanye kakhulu, emehlweni kwimizuzu okanye iiyure, yingxamiseko yezonyango. Ukuba oku kwenzeka emva kokwenzakala entloko okanye ngeempawu zesilumkiso sestroke, fowunela u-1990 (inkonzo ye-ambulensi engxamisekileyo yaseSri Lanka) ngoko nangoko.

Okokugqibela, izinto ekufuneka uzikhumbule (Umyalezo Wokuya Ekhaya)

Ukukhanya kwamehlo akho kubalulekile ngaphezu nje kweembongo zothando. Ukukhanya okubonakaliswa kumphezulu weliso lakho kunika oogqirha ulwazi oluninzi olubalulekileyo malunga nendawo yamehlo akho. Olu vavanyo lwe-corneal light reflex (olwaziwa ngokuba luvavanyo lweHirschberg) luluncedo kakhulu kubantwana abancinci nakubantu abadala ngokufanayo. Luvavanyo olukhawulezayo nolungenabuhlungu.

Ukuba unemibuzo malunga nolu vavanyo okanye indawo amehlo akho ami kuyo, ungathandabuzi ukuthetha nogqirha wakho okanye ugqirha wamehlo. Baza kukwazi ukukuxelela okungakumbi ngalo kwaye bakuncede uphelise nakuphi na ukuthandabuza onokuba nakho. Khumbula, amehlo akho sisitho esixabisekileyo. Yiyo loo nto kubaluleke kakhulu ukuwanyamekela!

Ukuhlolwa kwamehlo , i-corneal light reflex, uvavanyo lweHirschberg, intshukumo yamehlo, iliso elivilaphayo, impilo yomntwana, impilo yamehlo
