An abnormal white or gray reflection seen in the pupil, instead of the normal red-orange reflection (red reflex) observed during ophthalmoscopy or flash photography. It is also known as Leukocoria (white pupil).
read more about white light reflex ...The white reflex is a critical diagnostic sign, particularly in pediatrics, as it indicates an opacity or mass blocking the visualization of the retina.
The most serious cause is Retinoblastoma (a malignant tumor). Other causes include congenital cataract, Coats' disease (retinal vascular anomaly), or persistent fetal vasculature.
Pediatricians and ophthalmologists screen for this reflex during routine exams using the ophthalmoscope to shine light into the pupil and observe the reflection.
The normal reflex is red-orange (red reflex), which is light reflecting off the vascular retina.
Because one of the main causes is retinoblastoma, a white reflex requires urgent referral and investigation to rule out a life-threatening, blinding malignancy.
Yes. A dense congenital cataract (clouding of the lens) prevents light from reaching the retina and causes a white or gray pupillary reflection.
