A white reflex: A white reflexion can be seen in a photograph where the flash has been used. Often one eye will have "red eye" which is normal but the other eye may look white, yellow or orange. This may be seen in just one or many photographs of the child.
A squint: A squint can be a sign of retinoblastoma, although a squint can also be nothing more than a squint. It is always worth having it checked out quickly just to make sure. Some people call a squint a "lazy eye"; it is where one or both eyes look in or out.
Red, sore or swollen eye without infection: A child's eye may become very red and enflamed for no reason. This sign is usually linked with other signs.
A change in color to the iris: The iris, the colored part of the eye, can sometimes change colour in one eye, sometimes only in one area.
An absence of 'red eye' in flash photographs: In a photograph where one eye has 'red eye' (which is normal) the other eye may look black or looks 'wrong'. This can also be a sign that something is not right.
Deterioration in vision: A child may have deterioration in their vision or they may have had poor vision from birth. You may notice that your child does not focus or fix & follow as well as other children or babies of the same age.
