b. noting any changes in the patient's visual field.
c. asking the patient to rate the pain using a 0 to 10 scale.
d. assessing the patient's depth perception when climbing stairs.

POAG develops slowly and without symptoms except for a gradual loss of visual fields. Acute closed-angle glaucoma may present with excruciating pain, colored halos, and blurred vision. Problems with depth perception are not associated with POAG.
