Hello. This is Dr Geyik and I will be assisting you today.

Is your baby growing and developing normally or have you noticed anything else unusual?

Customer: replied 10 days ago.
Everything seems ok
Expert:  Dr Geyik, MBBS replied 10 days ago.

Finally, is there anyone else whose pupil size is different or was different as a baby?

Customer: replied 10 days ago.
Mine aren't different sizes from each other but I've got huge pupils & a squint eye I can't remember the name they gave it
Expert:  Dr Geyik, MBBS replied 10 days ago.

In dim light or dark, the size of the pupils goes up to accommodate more light to see better. Both pupils normally increase in size equally.

In some babies, one pupil can be bigger or smaller than the other one and this doesn't always mean there is an underlying cause. It could be just a benign variation or rarely a genetic cause.

If they don't have any other symptoms, then I do not suspect anything sinister; but you should still see their GP for a routine assessment to ensure we are not missing anything else.

What other symptoms would be worrying

If you noticed that he has vision problems, signs of pain or headache, vomiting, developmental delay, etc?
