Patients who are monocular from either ptosis or ocular patching and patients with diplopia should not climb on high places, drive a vehicle, or operate heavy machinery.

Patients should avoid any other activity where limitation of peripheral vision poses danger.

The monocular nasal crescent is lost when one eye is occluded, which effectively shrinks the field by some 20-30° on the side of the closed eye. Loss of depth perception with one eye poses another set of potential risks for activities that depend on accurate assessment of depth.
