Answer 1

In the evaluation of the levator muscle to determine myogenic ptosis, a measurement less than -2mm would be considered abnormal.

Step-by-step explanation:

In the evaluation of the levator muscle to determine myogenic ptosis, a measurement less than -2mm would be considered abnormal. Myogenic ptosis refers to drooping of the upper eyelid due to a problem with the levator muscle. The levator muscle is responsible for lifting the eyelid, and when it is not functioning properly, the eyelid droops.
