Question about describing ocular motility

I know that when describing decreased ocular motility, many people draw out a diagram with numbers in each direction to indicate deficits. So I'm reading this note today that showed your standard cross and 4 numbers in each direction. For example, 60 superior, 15, medial, 30 lateral and inferior. So with numerical notations, do larger values indicate greater eye motility, or less?

This sounds like muscle balance. Was it a cross or tic tac toe diagram. If the later then those numbers are showing deviation in prism diopters.

Usually motility is graded from 0 ( no trouble) to -4 ( complete deficit).

It was a cross. And yes, I've usually seen the 0 to -4 scale before. My other question is, when people describe "full"/normal ocular motility, does it have to be 0 in each direction, or can you have, say -1 in two directions and 0 in two other directions? My reason for asking is that in the exact same diagram I saw today, it was labeled 60, 45, 45, 45, then next to it, it was labeled "full". I guess I'm just a little confused about that different notations that are out there, and how those are interpreted.

Like MR said, it was probably a deviation measured in diopters, and Full referring to motility. You can have a decrease in motility in any number of directions

I looked at the same note again and there was indeed a tic tae toe diagram next to it. In the diagram, a zero with a slash through it was drawn in the center and in the middle of every side of the tic tac toe. What would that indicate?

So that one is showing muscle balance. It shows the amount of deviation in each direction of gaze. The other cross must be eom and they must just notate it with different numbers.

Ok, thanks!

Sorry guys, got another basic question:

When the retina for both eyes are drawn in a note, the drawing on the left = right eye, correct? And the drawing on the right = left eye?

^ Yes. Most of the exam is written from the examiner's perspective except for the visual field. Visual fields are usually documented from the patient's perspective (ie, what the patient sees).

The zero with the slash means "ortho," i.e., the eyes were aligned in those directions of gaze.

Gotcha, thanks.
