When doing an exam, if I checked the right eye by covering the lefy and the left eye by covering the right, and they are both 20/20. Is it correct to put, OU 20/20 and OS 20/20? OR…can i document, OS 20/20? In other words, if they both tested 20/20, do I have to document them separately. Or can I simply put OU 20/20?
Thank you

Please ignore my previous question. I got my letters mixed up. The question below makes better sense. Thanks

You have to document it as OD 20/20 and OS 20/20. OU 20/? means the vision you are getting without covering either eye.

The explanation is very helpful. Just wondering, “oculus dexter”, “oculus sinister” and “oculus uterque”, are they Latin or other language origins? Thanks.

They are Latin!

OU OS and OD are for accurately documenting each or both eye, since the pronunciations are in Latin, we must understand that Latin is considered a dead language, so I feel pronunciation is not as important as understanding the symbolism.
