What are the two methods used to set a target IOP?

• A. Visual field criteria and optic nerve color
• B. Percent reduction from pre-treatment max IOP, and IOP range
• C. Age and race
• D. Blood pressure and heart rate

Answer: (B)

Setting a target IOP means choosing a pressure level you aim to keep the eye at to slow or prevent glaucoma progression. The first approach personalizes the goal by taking a percentage drop from the highest IOP the patient had before treatment—so the target reflects how high pressure could get historically and ensures a meaningful reduction. The second approach looks at the range of IOP values the patient has tolerated without progression; the target is chosen to sit within that range or slightly below its lower end to provide a safety margin. Together, these methods tailor the goal to both the patient’s past peak pressure and how their IOP has behaved over time, which helps balance effectiveness with safety. Other factors like visual field loss, optic nerve appearance, age, race, blood pressure, or heart rate aren’t the primary ways to set the target IOP, though they may influence overall risk assessment and management decisions.
