To be considered normal, a red reflex should emanate from both eyes and be symmetric in character. Dark spots in the red reflex, a markedly diminished reflex, the presence of a white reflex, or asymmetry of the reflexes (Bruckner reflex) are all indications for referral to an ophthalmologist who is experienced in the examination of children.

The red reflex was documented as positive or abnormal if the reflex was white, yellow, nonuniform, absent, asymmetric, markedly diminished, unusually brighter, or having spots in it. Comprehensive eye examinations, serving as the reference standard, included external inspection, pupil examination, hand-held slit lamp examination, and RetCam imaging.
What does red reflex indicate?
Examination of pupil reflections, also known as the red reflex text, can reveal problems in the cornea, lens and sometimes the vitreous, and is particularly useful in young children. These photographs show what can occur in the case of certain major eye conditions, the most serious of which is retinoblastoma.
Is red reflex normal?
To be considered normal, a red reflex should be seen in both eyes symmetrically and equivalent in color, intensity, and clarity. An absent or black reflex may indicate an obstruction that is preventing light from reflecting back to the examiner.

An absent red reflex usually suggests sight-threatening pathology (cataract) and may mean life-threatening pathology (retinoblastoma).
What causes abnormal red reflex?
An abnormal red reflex can result from mucus or other foreign bodies in the tear film, corneal opacities, aqueous opacities, iris abnormalities affecting the pupillary aperture (pupil), cataracts, vitreous opacities, and retinal abnormalities including tumors or chorioretinal colobomata.
At what age do you stop checking red reflex?
For the well-baby check up at 1 month, check for the red reflex. For visits from 2 to 18 months of age, in addition to the red reflex, you need to check for the corneal light reflexes and ocular mobility, as well as to perform cover- uncover tests.
What if red reflex is white?
The red reflex is either absent or white with leukocoria. This occurs because of abnormal reflection or blockage of light coming out of the eye. Pediatricians will refer patients with “abnormal red reflex” on their exam for a more thorough exam by a pediatric ophthalmologist.
What is a white reflex?
Leukocoria (also white pupillary reflex) is an abnormal white reflection from the retina of the eye. Leukocoria resembles eyeshine, but leukocoria can also occur in animals that lack eyeshine because their retina lacks a tapetum lucidum. Leucocoria. Other names. Leucocoria, white pupillary reflex.

Why do human eyes reflect red?
Let us explain. The problem with red pupil reflex in photography is a common one, especially in children because of their relatively large pupils. It occurs when the flash reflects off of the blood-rich retina. If both eyes show up red, that can indicate that all is well (normal).

How to treat red reflexes in the eye?
Instil a drop of tropicamide 0.5% into both eyes and reassess the red reflexes through dilated pupils. If the red reflex is still absent then an urgent referral should be made to the local paediatric ophthalmologist. Occasionally, a white reflex is seen instead of a dark one. This kind of reflex is the hallmark of a retinoblastoma in the eye; and it is the light reflecting from the tumour’s white surface that can be seen when light reflects from a certain angle ( Figure 3 ).
What does it mean when a paediatric ophthalmologist says there is no red reflex?
The single most important piece of clinical information that a paediatric ophthalmologist requires is the presence or absence of a red reflex. An absent red reflex usually suggests sight-threatening pathology (cataract) and may mean life-threatening pathology (retinoblastoma).
What is the BME reflex?
In a BME baby, it is symmetrical and similar to the red reflexes of the parents. It is often more like the sun than orange, but the parents should have similar reflexes.

What does it mean when your eyes are red?
In case of healthy eyes where there is no obstruction in the optical pathway, red reflex is present, which means that a reddish-orange reflection of light from the retina would be observed. Absence of red reflex is indicative of certain serious eye conditions, which is why, this test is conducted in newborns to rule out vision-related problems.
Why is my red reflex absent?
If the reddish-orange reflection of the light is not observed in one or both eyes, it implies that the red reflex is absent. This indicates the presence of an obstruction or abnormalities in the structures located at the back of the eye. In some cases, lack of symmetry in the red reflex might be indicative of unequal or high refractive errors.
Is the red reflex absent in infants?
