Rare eye problems
Often inherited (genetic diseases), these are rarely seen in young children but may be diagnosed 1st from around 10 to 20 years old. There are a large range of unusual or rare retinal diseases that children can develop.
The retina converts light rays to electric signals, and the optic nerve carries huge numbers of these signals to the brain all the time. 1.5 million nerve fibres exit the eyeball and travel to the brain where the information they carry is converted into what we “see”. If significant numbers of the fibres are damaged some of the signal never reaches the brain.
Children suffer less problems of the tissue around the eye than adults, and less overall cancers in or around it. But these are very important to diagnose and treat early.
