I would guess that the doctor is talking about a theoretical risk of retinoblastoma, a type of uncommon eye tumour found in babies, that can be induced by somatic mutations or inherited. Theoretically, radiation exposure might be a risk factor…

I still don’t get this.
How can sunlight shining on the mother induce a mutation in the foetus?
And if the condition is inherited than even direct radiation of the foetus isn’t going to change that. Either it was inherited or it wasn’t.
It seems like you are suggesting that the MOTHER can develop the mutation inher retina and somehow the tumour migrates to the foetus.
