Which group is not included in glaucoma sampling?

• A. Over age 60
• B. Under age 18
• C. Ages 45-60
• D. Ages 20-30

Answer: (B)

Glaucoma studies focus on adults because the condition is largely age-related, with prevalence increasing as people get older. Pediatric glaucoma exists but is rare and has different causes and patterns, so it’s treated as a separate area from standard glaucoma sampling. That’s why the group not included is those under 18 years old. The other age ranges shown—over 60, 45–60, and 20–30—fall within typical adult sampling frames where glaucoma is studied. If a study specifically looked at pediatric glaucoma, it would use a different design and eligible population.
