Hi there. I had severe retinopathy after the birth of my first child. I ended up having a bleed about a year later and thought I may lose the eye at one point. I was told not to conceive at this time.
I've now had five laser sessions on my left eye and four on my right,plus a vitrectomy on my left eye. The retinopathy has stabilised and I got the go ahead to conceive and am now 14 weeks pregnant with my second.
Two things I did which were unfortunately quite costly but totally worth it. I paid to see the top consultant in my part of the world to ask his opinion on whether it was safe to conceive again. He said yes, but to have 'top up' laser to protect my eyes. This is laser which is not essential at the time but additional laser to prevent any further problems. You're unlikely to get this on the NHS as they only laser when they have to (although it's worth a try).
Hopefully this is now all keeping me stable - I'm 3 months in and so far no sign of any problems.
I think it depends on how bad your eyes are and how much laser you've already had, but I was pretty bad, my left eye was riddled with really bad retinopathy that would probably have caused a detachment had I not had the operation. My right eye was not as bad but not great either. And I was told it would probably be ok to have a second child.
One word of warning though it can take many months after childbirth for the retinopathy to develop. I had a little bit of laser in one eye towards the end of my pregnancy, about a year later, my other eye caught up and went a bit mental which is why I eventually needed the op.
Good luck
