ocd or vision therapy

My child is 5 yrs old and diagnosed with autism.  Since he could walk he loved opening and closing doors besides opening /dvd and in and out vcr etc.  My main concern is doors b/c it affects our every day living when we go out.  We started him on Prozac 8 wks ago and school has been great.  But home is still a nightmare.  I can't go anywhere with him b/c he just wants doors or elevators.  So am wondering now is this OCD or vision thing.  He also loves to watch numbers count down...microwave.  As commonly told to me, he is very unique...smart, good eye contact at times and still puzzles doctors.  His Hyperactivity with his door behavior is what keeps him unable to handle.  No social groups, or outings nor babysitters.  Any suggestions?
