She's a neighbour I met for the first time yesterday. I thought it was unusual when I met her yesterday, and she asked us over for coffee this morning - I noticed it again. Basically with - I think - both her eyes you get a white reflection back from the back of they eye - sort of like redeye in a photo - but white. It wasn't cataracts as it wasn't milky or at the front. Perhaps one of you knows more about this than me, but I am guessing she and her family all know about it.
The only thing is I have read of people having this noticed by other people (from a photo in one case) - and it's an indicator of an eye cancer (retinoblastoma).
is it something that people just 'have'??
