Red Reflex
The Red Reflex is a reflection from the lining of the eye that is observed when using an ophthalmoscope or retinoscope. It is a crucial part of the eye examination, particularly in infants and children, as it can reveal significant information about the health of the eye and the visual system.
Overview[edit | edit source]
The red reflex test is a routine screening examination performed on newborns and infants. The test involves shining a light into the eye and observing the reflection off the retina. The normal appearance is a reddish-orange reflection, similar to the "red eye" seen in flash photography. Abnormalities in the red reflex can indicate a range of eye diseases and conditions.
Procedure[edit | edit source]
The red reflex test is performed using an ophthalmoscope, a handheld device that shines a light through the pupil and allows the examiner to see the back of the eye. The patient is usually asked to look in the distance, and the examiner observes the reflection from the retina.
Abnormalities[edit | edit source]
Abnormalities in the red reflex can indicate a range of eye diseases and conditions. These may include cataracts, retinoblastoma, retinal detachment, and refractive errors.
Importance in Pediatric Examination[edit | edit source]
The red reflex examination is particularly important in infants and children. It is a crucial part of the newborn examination and is usually repeated at all routine child health checks. An abnormal red reflex is a significant finding and requires further investigation by an ophthalmologist.
