The redreflex, more accurately known as the fundus reflex, is the coloration of the pupil from light reflecting off the back inner surface of your eye. In children, testing for the fundus reflex can help catch serious eye issues, including a rare form of eye cancer.
The redreflextest uses transmission of light from an ophthalmoscope through all the normally transparent parts of a subject's eye, including the tear film, cornea, aqueous humor, crystalline lens, and vitreous humor.
Redreflextesting is a valuable tool for detection of abnormalities in the normally transparent visual axis or in the retina. Loss of transparency in any of these structures can alter the redreflex, including from front to back; the tear film, cornea, aqueous humor, lens, vitreous gel, and retina.
The red reflex from the retina is a quick and non-invasive test used to identify opacities in the visual axis, such as a corneal abnormality or cataract, as well as abnormalities in the posterior segment of the eye, such as retinoblastoma.
Generally, it is a physical exam done on neonates and children by healthcare providers but occasionally occurs in flash photography seen when the pupil does not have enough time to constrict and reflects the fundus known as the red-eye effect.
The Bruckner Test is a test which is performed with a direct ophthalmoscope to identify gross ametropia and other abnormalities of the eye. A large circle aperture of Direct Ophthalmoscope is used to illuminate both eye simultaneously and reflex of both eyes are observed and compared.
The redreflextest is a simple, non-invasive screening method that involves shining a light into the pupil to observe the reflection from the back of the eye, similar to the “red eye” effect seen in flash photography.
The redreflex should be checked at every well-child visit. This video offers instruction on how to perform this test along with examples of normal and abnormal results.
The redreflex (RR) test, also known as the Bruckner test, is vital for the early detection of potential eye health and vision problems in neonates, infants and children.2 Numerous eye disorders of the neonatal and childhood period can lead to permanent visual impairment.
To address these issues, we conducted an exploratory study to gather objective and subjective evidence of the ‘normal’ appearance of this test across different ethnic groups.
