Emphasize the following points during the examination to distinguish POAG from either secondary causes of glaucoma or from OHT in patients with only elevated IOP and no damage.

Compare visual acuity with previous known acuities. If declining, rule out secondary causes of vision loss, whether it is from cataracts, age-related macular degeneration (ARMD), ocular surface disorders (eg, dry eye), or adverse effects from topical medications (especially if using miotics).
