CLP,
Orbital ultrasonography (OU),is a test which evaluates soft tissue causing exopthalmos. It is commonly used by a surgeon prior to keratoplasty or cataract surgery with great confidence intead of beginning surgery blindly. It’s a non invasive procedure and is well tolerated.
Another frequent use is determination of certain ocular measurements as depth and global length.
Hope this helps a little,:>)
