Anatomy scan results. Outer orbital diameter

We went for our anatomy scan at 21 weeks 2 days. This is after a scary first trimester with a very slightly thickened NT. All chromosomal tests, etc came back normal. So the NT wasn’t indicative of anything. And at the anatomy scan we were told everything looked great/normal. Such a relief.

However, I just got the report back from the scan which included all of the measurements taken with the percentile our son lies. He was pretty average on most things...within the 50-57th percentile range. A couple of things were big. Feet at over 95th percentile (my husband is tall and had big feet his whole life to prove he’d grow even though he was a late bloomer. So we laughed at him having his dads feet)

But the only item that was in a range that concerns me was the OOD..outer orbital diameter. The distance between the outer edge of each of the eyes. He was in the 18th percentile. The IOD (distance between the inner edge of each eye) was in the 56th. So it doesn’t seem like his eyes are abnormally close together or anything. I’m just trying to figure out what the small OOD could mean. Just small-ish eye sockets in general?

I have an appointment tomorrow so it’s on my list to ask. Just wondering if anyone has any idea.
