there is no right or wrong answer, because every condition is different, and every person is different.
My xh has a genetic condition which results in visual impairment. Virtually his whole family has it, added to that, his mum has a different genetic condition, although neither of her children have inherited that one, only the one from his dad.
As someone who is myself VI, I knew that if I had a baby with VI I would be best placed to deal with it. but I still weighed up the odds when I was deciding about whether to have children.
When ds was born he was tested, and found not to have inherited the condition. And I have to say that while being VI would not have been the end of the world or a serious disability, I am glad that he hadn't inherited a condition which meant he would be VI. HAd he inherited it I think I would have actually felt guilty because I would have had a child knowing that they might inherit the condition.
For me what mattered was the percentage. I had a 50/50 chance of having a baby with a genetic condition. therefore there was a 50% chance my baby wouldn't have inherited it. If the ods had been greater I think I would have re-evaluated, and if it had been a 100% chance I wouldn't have had children.
It's one thing to take a chance on your child inheriting a condition, quite another to knowingly inflict that condition on them. IMO.
I don't consider visual impairment to be a life-limiting or debilitating condition. I love my life. I am fully independent, but I do think that any kind of disability should be thought about if there is a chance of your child having it, and the implications of doing so.
