Hi.
I've just found this forum while searching for something else, and I wish I'd found it earlier!
I was born with congenital cataracts, and am now legally blind, and my younger two children (boy and girl twins) have also got it - I didn't know it was a genetic thing until they were born.
My son has also had glaucoma in his left eye.
My kids are nearly ten, and they are doing really well. Those parents with kids getting ready to go into preschool or childcare, from personal experience, you need to go to the place and let them know, and try and let them know EXACTLY what your child can and can't see. Do it early, like two or three months before they start there. Tell them how you deal with situations at home so they can do the same there. I did this with both playgroup and preschool, and the teachers said it was useful to have advance warning, as well as info on what to do, because they could look stuff up to help as well and not just get thrown in the deep end.
Hope everyone's operations and tests go okay.
Michelle
