What is a red reflex?
Red Reflex refers to a reddish reflection that is observed when the eye doctor shines light into the healthy eye of the patient. This reflex is produced when a doctor's light, called an ophthalmoscope, passes through the pupil and reflects back from the retinal cells on the back of the eye. The clear transmission of this reddish light shows that the eye is healthy, while the lack of red reflex or the presence of stains or asymmetry between the two eyes can indicate different two weeks and two months of life. The test should then be repeated regularly as needed throughout the child's time. Most abnormalities detected by this test dramatically improved the outcome when detected early, and for this reason this test is ordered by law in some countries. The red reflex test should be carried out in a darkened room and the doctor should shine light into the child's eye from a distance of approximately one foot (0.3 m).
the most common abnormalities observedIn this test, the production of white light and/or whitish spots or no light, rather than a typical reddish color, are at all. This usually shows that something unusual in the eye blocks the transmission of light through the pupil and on the retina. The absence of light is usually caused by a certain type of bleeding or bleeding in the eye, but can also be caused by any large foreign object in the eye that prevents the transmission of light. Asymmetric red reflex can be a sign of serious developmental abnormalities, but it can also simply indicate that both eyes have completely different refractive errors.
abnormal white or white spots can be caused by cataract or glaucoma. They may also be caused by retina, such as retina or retina infections. All these conditions may endanger the eyes of the child and should therefore be immediately solved any red reflective abnormality.
Another abnormality that can cause whitish light or stains in the red reflex test is the presence ofT Retinoblastoma or eye tumor, which usually occurs in young children. This tumor tends to occur in families, but may also occur in children who do not have a family history of this condition. It may be possible to remove this tumor by laser surgery, although larger and aggressive tumors can lead to eye loss if it is the only way to stop cancer. The result of the retinoblastoma is usually good if it is caught in front of the tumor to spread out of the eyes, but the prognosis is less favorable after spreading.
