, Lichtreflex
Voorbereiding
Doel: het grove screenen op het vermogen om te fixeren en het objectief schatten van de
scheelzienshoek met behulp van een fixatielichtje.
Leg uit: dat je een test gaat doen om te kijken naar de oogstand
Omstandigheden: verlichting normaal, met gebruikelijke refractieve correctie
Benodigdheden: fixatielampje / transilluminator
Toepassing: patiënten met een manifest scheelzienshoek, die onvoldoende coöperatief zijn.
Uitvoering
Leg de test uit
Ga recht voor de cliënt zitten en laat de cliënt op ooghoogte naar een fixatielichtje kijken op
30cm.
o Ook uitvoerbaar op 1m, 2,5m, 5m en 6m.
Vergelijk de positie van de lichtreflexen OD met OS.
Bepaal de plaats van het reflexbeeldje
Schat de grootte van de scheelzienshoek.
Voer deze test uit met en zonder correctie.
Voer deze test uit met en zonder torticollis.
Noteer de uitkomst.
Notatie
Noteer de gebruikte test LR
Noteer de afstand
Noteer de uitkomst met en zonder correctie
Noteer alle factoren die opvallen betreffende:
o Plaats van de reflexbeeldjes
o Positieve / negatieve hoek kappa
o Symmetrisch of asymmetrisch, indien asymmetrisch wordt de grootte en richting van
de geschatte scheelzienshoek en het aangedane oog genoteerd.
o Nystagmus
o Pupilafwijkingen (bv coloboom of anisocorieMogelijkheid tot fixeren
o Stands veranderingen
o Oogstand
o Unilateraal of alternerend strabismus
o Helderheid corneae
o Littekens
o Irisafwijkingen
Voorbeeld:
LR: recht
LR: sp pos hoek kappa
