This was my sons day when he was 2-3 years old ,pacing ,walking along counters ,table tops ,the backs of chairs etc etc...,he would look sidways out of the corner of his eye the whole time,he would also line things up to do this ,and even did it in public alot.
The good news is there was nothing wrong with his eyes,and at around 3.5 it started to slowdown and had almost disappeared until school started ,its back but not as often,and now he mostly does it when he spins.
Good Luck,Linda
I think it's definitely worth a professional pediatric eye exam. Your child doesn't have to know how to talk or read symbols or letters to get his vision evaluated. The issue might not be near or far sightedness, but an issue of how well the eyes cooperate together, which I understand can affect depth perception and even give double vision.
Here's a checklist for sensory issues, which might be helpful to you. The website has lots of ideas for various sensory activities, so it's worth a browse.

As far as stimming goes, here's an article that I think is a very good introduction to the subject, including what to do about it.

Good luck with everything.
My son is 25 months old, and is doing really really great with all of his therapies, the main concern I have for him is stimming behaviors, they seem to be on the rise and I am not sure what to do about it. Almost all of his stimming is visual in nature, he paces perimeters especially those with lines or special angles, flushes toilets to watch the swirl, closely examines objects, walks along our kitchen counters looking at the angle of the countertops, he even looks at the walls in our house this way, I can go on and on about the odd way he looks at things that would not be of interest to most kids :) I know his vision is OK because he can see the teeny tiniest plane in the sky (loves airplanes) , I wonder though if he doesn't have a problem with depth perception, I notice when we are at the playground, he often gets freaked out if he looks through the grates that the playgym's are often constructed with, like he doesn't know to focus on the grate ( floor he is standing on ) or the ground, He sometimes drops to his knees and starts whining if he looks at it for too long and it's like he gets dizzy and can't stand up. Is this common with ASD kids, and is there anything I can do about it? I know the stimming itself is common, does anyone know of any more socially accepted alternate ways I can give him the sensory input he needs that may help him out? Could there be a physical cause for this type of stimming? I just can't imagine why he needs to do it and why so frequently....
