Hoping for someone has an experience that could help. DD 5 weeks had very noticeable difference in her pupil size on Wednesday evening. I’m attaching a pic. She was completely well within herself and the only thing that could have been a factor is that her right eye - which had the larger pupil - had a tiny bit of fluff stuck in it a few mins earlier. No idea if that’s relevant.
she’s seen the gp who checked her red reflection reflex and was satisfied nothing is wrong. He said this can be normal in young babies. He has made a non-urgent referral to opthalmology anyway. Since weds evening the difference seems to have settled down and I think today I’d say i haven’t noticed it at all. When it was noticeable yesterday it was more so in dim light. In bright light both pupils were equally small. The gp observed this too.
i have read lots online about how common this can be however the thing concerning me is the scale of the difference on Wednesday night. Everything I’m reading about what’s normal would suggest hers was too significant to be physiological (and therefore not a concern). So I’m wondering if anyone else has experienced similar. She’s had no droopiness over either eye and as I said is well within herself. I am most concerned about Horner’s syndrome as her birth was an elective c section which would rule out birth trauma as a cause and leave some scarier options - hence the worry!
