Ukukhanya okuncane emehlweni kungasho okuningi! - Singakhuluma ngokuhlolwa kwe-Corneal Light Reflex (ukuhlolwa kwe-Hirschberg)?

Wake wezwa ngalolu vivinyo olubizwa ngokuthi i-Corneal Light Reflex Test? Udokotela wakho kungenzeka ukuthi ukwenzele wena noma ingane yakho encane lokhu. Luhlolo olulula kakhulu, olungenabuhlungu olungenziwa ngomzuzu noma emibili. Ukuze kube sobala, lwenziwa ukuze kubonakale ukuthi amehlo akho aqondene kahle yini.

Lokhu kubaluleke kakhulu ukuthola izimo ezifana ne-strabismus noma i-amblyopia (iso elivilaphayo) kusenesikhathi. Cabanga ngakho, ezinye izingane ezincane zingase ziphenduke kancane ohlangothini olufanayo. Lokhu kuhlolwa kusiza ekutholeni ngokushesha izinto ezinjalo.
• Ngesikhathi sokuhlolwa kwempilo kwaminyaka yonke kwabantu abadala: Odokotela bangakwenza lokhu ngesikhathi sokuhlolwa kwakho ngokomzimba kwaminyaka yonke noma ukuhlolwa kwezinzwa. Lokhu kuyingxenye yenqubo ejwayelekile yokuhlola impilo.

Ngakho-ke uyabona, lesi isivivinyo esibalulekile esingase senziwe yinoma ubani, kusukela enganeni encane kuya kumuntu omdala.

Lolu vivinyo lusebenza kanjani?

Kulula kakhulu. Udokotela ubheka ingxenye ecacile yeso lakho (i-cornea) ezungeze indandatho emnyama , ngenkathi ekhanyisa ukukhanya okuvela kuthoshi elincane emehlweni akho. Uma amehlo akho eqondene kahle, ukukhanya okuvela kuthoshi kufanele kube sendaweni efanayo kuwo womabili amehlo, okungukuthi, engxenyeni efanayo yendandatho emnyama.

Cabanga nje, uma amehlo akho ebefana namakhamera amabili, okwenzekayo lapha kufana nokuhlola ukuthi womabili amakhamera agxile yini esihlokweni esifanayo.

Yilokho kuphela. Lokhu kuzophela ngemizuzwana embalwa.

Kwenzekani ngemva kokuhlolwa?

Okwenzekayo ngemva kokuhlolwa kuncike kulokho udokotela akubonayo. Kunezinto ezimbili eziyinhloko ezingenzeka:

• Uma amehlo akho eqondene kahle: Akukho nkinga. Udokotela uzokubhala lokhu kurekhodi lakho lezokwelapha bese eqhubekela ezingxenyeni ezilandelayo zokuhlolwa.
• Uma amehlo akho ebonakala engaqondile: Uma kunjalo, udokotela wakho angenza ezinye izivivinyo ezimbalwa ezilula ukuqinisekisa ukungahambisani kahle nokulinganisa ukuthi kuhamba ibanga elingakanani. Ungakhathazeki, konke kulula kakhulu.

Ithini imiphumela yalolu vivinyo?

Udokotela uzokutshela ukuthi kukhona yini ukungahambi kahle emehlweni akho, kungaba ngesikhathi sokuhlolwa noma ngemva kokuphela kwawo.

• Uma amehlo esesimweni esijwayelekile: okungukuthi, uma ukukhanya kusendaweni efanayo emehlweni womabili, udokotela uzokuphawula lokhu embikweni wakho ngegama elithi "symmetry" noma elithi "ortho." Igama elithi "Ortho" lisho isiGreki elithi "straight."
• Uma uneso eliphambene: Ngezinye izikhathi, noma ngabe awunalo ngempela iso eliphambene, lingabonakala njengelinye. Lokhu kubizwa ngokuthi i-pseudostrabismus . Lokhu kungabangelwa izici ezithile zobuso bakho. Isibonelo, abanye abantu banezimbobo ze-epicanthal ezinkopheni zabo, noma izinguquko endaweni yamathambo abo obuso, noma uma ibanga elisuka phakathi kweso elimnyama liye phakathi nekhala (ibanga le-pupillary) lingafani nhlangothi zombili. Yingakho odokotela benza ezinye izivivinyo ukuqinisekisa lokhu.

Uma kuqinisekiswa ukuthi kukhona ngempela ukudikiza emehlweni, udokotela uzophawula nokuthi hlobo luni lokudikiza emehlweni. Nazi ezinye izibonelo:

• I-Esotropia: Iso elilodwa noma womabili aphendukela ngaphakathi ekhaleni.
• I-Exotropia: Iso elilodwa noma womabili aphendukela ngaphandle.
• I-Hypertropia: Iso elilodwa libekwe phezulu kunelinye.
• I-Hypotropia: Iso elilodwa libekwe phansi kunelinye.

Ungakhathazeki uma la magama ebonakala enzima kuwe. Udokotela uzokuchazela wona ngamazwi alula.

Uma ukudikiza kwamehlo kuqinisekiswa, yini oyenzayo ngokulandelayo?

Uma udokotela wezingane noma womndeni wakho ethola ukuthi wena (noma ingane oyinakekelayo) ninekhala elisesweni lakho, bazokudlulisela kudokotela wamehlo . Udokotela wamehlo angahlonza imbangela eqondile yokukhala futhi akutshele ukuthi yiluphi ukwelashwa okudingekayo.

Into ebaluleke kakhulu ukuqaphela lezi zimo ezinganeni ezincane kusenesikhathi bese uqala ukwelashwa. Kulapho kuphela lapho imiphumela emihle kakhulu ingatholakala khona.

Kuthiwani uma lokhu kudonswa kubangelwa inkinga yobuchopho?

Ngezinye izikhathi, odokotela bezinzwa basebenzisa lolu vivinyo lwe-corneal light reflex ukuhlola izinkinga zobuchopho. Isibonelo, lolu vivinyo lungabaluleka ezimweni ezifana nesifo sohlangothi noma ukuxhuzula . Ezimweni ezinjalo, izinyathelo ezilandelayo kanye nokwelashwa kuzoncika embangela eyinhloko kanye nezinye izici eziningana. Udokotela wakho uzokuchazela lokhu ngaleso sikhathi.

Kufanele ngimbone nini udokotela?

Njengoba ukudikiza kwamehlo kukhula kancane kancane, kungase kube nzima ukukubona ekuqaleni.

• Uma ubona noma yiziphi izimpawu zokufiphala emehlweni engane encane oyinakekelayo, hlela isikhathi sokubonana nodokotela wezingane ngokushesha okukhulu. Izimo ezifana ne -lazy eye (amblyopia) zingelapheka ngokuphelele uma zelashwa kusenesikhathi. Kodwa-ke, uma zingalashwanga ngemva kweminyaka ethile, zingaholela ekulahlekelweni umbono unomphela. Ngakho-ke, kungcono ukungalibazisi ukuxilongwa nokwelashwa.
• Uma umuntu omdala ebona ukugoba kancane kancane kwamehlo, kufanele nakanjani ubonane nodokotela wamehlo.

Uma uhlangabezana nokulahlekelwa umbono okungazelelwe, okukhulu, noma ngisho nokweqile, phakathi nemizuzu noma amahora, kuyisimo esiphuthumayo sezokwelapha. Uma lokhu kwenzeka ngemva kokulimala ekhanda noma ngezimpawu zokuxwayisa ngesifo sohlangothi, shayela u-1990 (isevisi ye-ambulensi ephuthumayo yaseSri Lanka) ngokushesha.
